Chapter 1 Introduction Product Description The DIGITAL MultiSwitch 300 is a 12-port Fast Ethernet switch featuring eight autonegotiating 10/100BaseTX ports and up to four additional 10/100BaseTX/FX uplink ports. The MultiSwitch 300 provides a cost-effective solution for increasing the available bandwidth and distance of Fast Ethernet installations by dividing the network into segments and insulating each from the others’ local traffic.
The MultiSwitch 300 can operate as a standalone unit or with any other Ethernet offering from Digital Equipment Corporation. The unit does not require an NMS agent; however, it can be monitored and controlled through any SNMP-based NMS, if desired.
Features Features • 8 RJ45 STP autonegotiating 10/100 ports • Two expansion slots supporting up to 2 TX, 2 FX • Standard 19-inch rack-mount chassis (rack-mount kit included) • Auto-ranging power supply (automatically adjusts to any voltage between 90 Vac and 264 Vac at 50/60 Hz) • Half/full duplex selectable on each port via management • Flow control selectable on each port • 4096 address cache entries • Extensive custom filtering table • Serial console port with password protection • Do
Switch and Network Management Systems Switch and Network Management Systems The MultiSwitch 300 can be monitored and controlled through the DIGITAL MultiSwitch 300 Manager application, or through a generic SNMP NMS. See the DIGITAL MultiSwitch 300 Manager User’s Guide for information about how the DIGITAL NMS works. The MultiSwitch 300 does not require an NMS; however, network management functions greatly assist monitoring and controlling your network.
Chapter 2 Typical Configurations Configuring Your Network Links to a file server and links between switches often create bandwidth bottlenecks. When a dedicated 10 Mb/s link is not fast enough, or when a network-wide upgrade path is planned, Fast Ethernet is a viable solution. Links to a File Server Intense client/server traffic on the LAN may limit the overall performance of a network.
Finally, if a network’s bandwidth needs outstrip even 100 Mb/s shared workgroups, the MultiSwitch 300 can be used with the DIGITAL MultiSwitch 600 family of products to create a fully switched Fast Ethernet network.
Configuration Examples Configuration Examples Single Server Environment In a network with a single server, or even in a collapsed backbone with a single server, a good way to achieve bandwidth improvement is to use a dedicated 100 Mb/s Fast Ethernet link to the server. Both the 10 Mb/s workgroups and the 100 Mb/s server can be connected directly to the MultiSwitch 300 (Figure 2-1).
Configuration Examples Multiple Server Environment With multiple servers, a variety of approaches may be taken depending on your network’s traffic patterns. If each of your network users has a particular primary server that they use, then that server should be connected to one of the fast ports of the MultiSwitch 612EX.
Configuration Examples 100 Mb/s Environment In a 100 Mb/s environment, workgroup clients should be connected to a 100 Mb/s hub such as the MultiSwitch Hub 612TX (Figure 2-3). All hubs should be connected to the MultiSwitch 300. By connecting the hubs to a switched environment, the 100 Mb/s BaseTX distance limitation applies only to the workgroups.
Configuration Examples Multiple Server/WAN Environment If the users typically utilize more than one server extensively, then it may be beneficial to configure their network so that machines that serve multiple groups are given their own port on the switch. For instance, suppose that there are several departments, each with its own file server, and there is a single firewall router connected to the backbone.
Excessive Flow Control Excessive Flow Control During times of peak network usage, you may occasionally see the flow control indicator (Fc) flash. This is normal. However, either of the following conditions could indicate a problem with your network configuration: if the indicator stays lit for more than a few seconds at a time, or there is an excessive number of flow controls reported by the NMS.
Full-Duplex Flow Control Full-Duplex Flow Control Normally, flow control is not available on full-duplex ports. This is because the switch generates flow controls by sending a JAM signal whenever it is unable to forward a frame. When the host NIC receives the JAM, it will retransmit the packet from hardware buffers. This is faster than relying on higher level software transport layers, which must first detect the dropped packet via a time-out mechanism, then regenerate and re-queue it.
Repeater Count Limits Repeater Count Limits A switch does not count as a repeater. Each of the segments connected to a switch port can support a full Ethernet LAN; there can be up to two Class II hubs or one Class I hub between the switch and any station(s). If you have specific questions about your network configuration, or have a particularly difficult network, please call your DIGITAL Service Representative. (See Chapter 4, MultiSwitch 300 Troubleshooting.
Chapter 3 Installation and Setup Installing the MultiSwitch 300 The following instructions will enable you to successfully install the MultiSwitch 300 in your network. Step 1: Determine the Best Location for the Switch Install the unit in a 19-inch rack using the enclosed rackmount ears, or place the unit on a secure, flat surface after attaching the enclosed rubber feet.
To use full-duplex mode: • Step 4: Full-duplex mode may be selected via management. Consult Chapter 6, Accessing the SNMP Agent, or the DIGITAL MultiSwitch 300 Manager User’s Guide for port configuration. What to Do Next If you are using the MultiSwitch 300 as a standalone device (not under NMS control), you have completed the installation and setup of the Switch.
Using the MultiSwitch 300 Using the MultiSwitch 300 Operation of the switch requires minimal user intervention. The unit automatically learns the addresses of new stations as they appear, and will relearn addresses (up to a limit of 4096) of new stations dynamically, if the network is reconfigured. Understanding the LEDs Each of the 10/100 ports has six status LEDs, as shown in Figure 3-1. Xmt Lights when this port transmits packets.
Using the MultiSwitch 300 allowing simultaneous transmission and reception, eliminating collisions. With this combination, a 200 Mb/s link can be established between two switches separated by any supported distance. This should be more than sufficient for most LAN applications. TX Cabling The MultiSwitch 300 is an MDI-X device. Connections to other MDI-X devices, such as another MultiSwitch 300 or a hub, should be made with a crossed Category 5 patch cable (DIGITAL BN25G).
Chapter 4 Troubleshooting the MultiSwitch 300 Procedure for Troubleshooting If there are any operating problems with the MultiSwitch 300, follow the troubleshooting steps below (in order). If you find that the switch is still not functioning correctly, please contact your DIGITAL Service Representative. 1) Ensure that the unit is plugged into a grounded, functioning ac outlet providing between 90 Vac and 264 Vac at 50/60 Hz. Check the power fuse and replace it if blown.
8) Ensure that the equipment attached to the switch is properly configured. If you encounter any situations or problems you cannot solve, obtain, if possible, the following information, then contact your DIGITAL Service Representative: • The serial number of your switch and its hardware address. • The hardware version number from the label on the unit. • The firmware version number from the console screen or MultiSwitch 300 Manager application.
Chapter 5 The SNMP Agent Overview The MultiSwitch 300 contains a built-in SNMP agent running on the SNMP processor board. This allows each MultiSwitch 300 to be managed from a centralized management station with any SNMP-compliant NMS.
The MultiSwitch 300 may be managed by any SNMP manager that conforms to the above standards. It may be fully managed by the DIGITAL MultiSwitch 300 Manager application.
Chapter 6 Accessing the SNMP Agent Connecting to the Administrative Interface This section provides instructions for connecting a terminal to the console port on the right-hand side of the front panel of the switch. The terminal must be used for the initial setup of the SNMP Agent software and may be used to test the connection to the network management station. Cabling The console port is a serial port with a male DB-9 connector and a DTE-type pinout.
Configuring the SNMP Agent Configuring the SNMP Agent Logging In to the Administrative Interface The Administrative Interface is protected against usage by inappropriate personnel. To access the Administrative Interface, the Network Administrator has to provide a name and a password. Please Login username: userseven password: (not echoed) As configured at the factory, the password consists of a null string. To enter the first time, just press .
Configuring the SNMP Agent Testing the Installation After you have completed the installation and configured the IP address, use the Administrative Interface ping command to test for connectivity. The ping command sends an echo request to the host specified in the command line. For example, to test connectivity from the switch to a workstation with an IP address of 192.168.1.2, use the following command: SYS_console> ping 192.168.1.2 2 SYS_console> Use CTRL-C or ping-stop to stop the ping process 192.168.
Chapter 7 Using the Administrative Interface Features of the Administrative Interface The Administrative Interface provides the following: • Configuration of system parameters, including the serial line and/or the console’s parameters • Configuration of the switch’s SNMP Agent parameters • Configuration of the ports’ physical and bridging parameters • Network performance monitoring • A fail-safe backup for in-band management Entering Commands Enter commands by typing the command name followed by
If you enter a command incorrectly, a message is displayed indicating the type of error that occurred.
When, as a result of a command, more than one screen-full of text is to be printed, you may continue to scroll or stop the process: SYS_console> ip IP related commands -------------------------------------------------------------get-ip show current IP address set-ip set IP address get-ip-cfg show current IP configuration set-ip-cfg set IP address , netmask and broadcast clear-ip-cfg clears the NVRAM based IP configuration set-slip set slip IP address get-slip get slip IP address get-slip-cfg show current IP

Console Commands Console Commands The console commands contain a set of commands that allows you to configure the Administrative Interface parameters and user interface. ? Typing ? at the Administrative Interface prompt displays a list of all the available command topics and a short explanation about each. Typing one of the names on this list will yield a list of the commands under that topic.
Console Commands login The login command exits the Administrative Interface, but does not disconnect a Telnet session. This allows you to test a password (or other activity) without reconnecting. logout The logout command finishes the actual Administrative Interface session. Any further access requires that you log in again. set-prompt Usage: set-prompt The set-prompt command allows you to set a new command line prompt for the Administrative Interface.
Console Commands If the password change succeeds, the system responds accordingly: SYS_console> set-passwd Enter old password: Enter new password: Enter new password again: CLI running password changed CLI password change in NVRAM OK Password changed! SYS_console> _ Using the Administrative Interface 7-7
System Commands System Commands The system commands allow you to display and set the system-related parameters. sys-stat The sys-stat command displays general status information about the Ethernet switch and its SNMP Agent hardware and software: SYS_console> sys-stat MultiSwitch 300 SNMP Agent Software - Version V0.1x Feb 8 1997 01:27:29 SNMP Object ID is : < 1.3.6.1.4.1.36.2.15.3.
System Commands warm-reset The warm-reset command resets the SNMP Agent software without resetting the switch. Nevertheless, the switch configuration is changed according to the values stored in the NVRAM. This command permits you to refresh the switch configuration after a change of the NVRAM parameters. The statistics counters are also reset by the warm-reset command. cold-reset This command causes the switch to cold-reset. Cold reset is equivalent to power cycling the switch.
System Commands Sets the name of the file downloaded by TFTP. This name must match the name of the agent software file on the TFTP server. When TFTP is used, the per-packet retransmission timeout value on the server must be increased to 10 seconds because the SNMP Agent must first erase its flash EEPROM, which takes about 30 seconds. get-rsw-file This command retrieves the SNMP Agent software’s remote filename.
System Commands For example: 00-00-F8-00-01-23 : public : private set-fg-parm Usage: set-fg-param This command sets the frame generator parameters. The dest and source parameters are dash-separated hardware addresses in hexadecimal. The fill_byte parameter is a single byte used to fill the entire packet except for the first 12 bytes. The length parameter is the total length of the packet excluding CRC.
System Commands firmware download software on the serial port. If, after 5 seconds, no download request is detected, the bootloader will run the self-test out of ROM space. The selftest then runs in 10-Mbit loopback mode and performs these three tests: 1) Loopback test. This tests the basic send/receive functionality of each port with varying frame sizes. 2) Broadcast test. This tests the basic forwarding capabilities of the bus by sending broadcast frames from each port with varying frame sizes.
IP Configuration Commands IP Configuration Commands This section lists general IP configuration commands available to the command line interface. Sections that follow cover additonal IP commands including commands pertaining to the ping ability of the SNMP Agent and pertinent features of the Address Resolution Protocol. get-ip Shows the device’s current IP address, if any. SYS_console> get-ip The device has no IP Address defined SYS_console> _ SYS_console> get-ip The device IP address is: 129.001.001.
IP Configuration Commands set-ip-cfg Usage: set-ip-cfg Sets IP address, network IP address, and broadcast IP address. If no IP configuration was previously set (as is the default factory configuration), the new values are used immediately and saved into NVRAM. If a previous IP configuration was being used, the new configuration is saved in NVRAM for the next session. To use the newly defined values immediately, reset the system using the warm-reset command.
IP Configuration Commands set-bootp Usage: set-bootp {enable|disable} This command enables or disables BootP. get-slip This command retrieves the current SLIP address. get-slip-cfg This command retrieves the current SLIP configuration. set-slip Usage: set-slip This command sets the SLIP address, see set-ip above for more information. set-slip-cfg Usage: set-slip-cfg This command sets the SLIP configuration.
IP Configuration Commands SYS_console> set-gatew 129.1.1.1 Device Default Gateway change in the NVRAM OK Device Default Gateway changed to : 129.1.1.1 SYS_console> get-gatew Device default gateway address is : 129.001.001.001 SYS_console> _ get-def-ttl This command returns the running default IP Time To Live value. This value (between 1 and 255) is the number of seconds this frame will be kept alive by routers along its path.
Ping Commands Ping Commands The ping command sends an ICMP echo request packet to a station. The ping process is independent of the process that serves the Administrative Interface console. Thus, the ping result (if any) printouts will be interleaved with the Administrative Interface input/output. Issuing further commands while the ping process is active is not recommended. Starting a new ping session while another one is active is not supported and an error message will be displayed.
Ping Commands If the host does not respond, the console prompt is printed and no output is added. Failure to get an echo response from a host may be due to: • A bad physical connection. • A non-existent or inactive host. • Network Unreachable no corresponding entry in the routing table. • Destination Unreachable the default gateway failed to route the datagram. • Outdated ARP table information which requires flushing the ARP table with the del-arp-entry command.
Address Resolution Protocol Commands Address Resolution Protocol Commands get-arp-tbl Shows the ARP table. The ARP table contains information relating IP addresses to MAC addresses and interface numbers. SYS_console> get-arp-tbl IfIndex IpAddress MAC Address ==================================================== 1 129.001.001.001 00-00-F8-2D-73-9C SYS_console> add-arp-entry 129.1.1.
SNMP Commands SNMP Commands This section lists commands pertinent to configuring the SNMP Agent itself, that is, access and trap configuration. It is split into two parts: SNMP community strings lists the access modifications, and the trap section lists SNMP traps configuration commands. SNMP Community Strings SNMP community strings authenticate access to the Management Information Base (MIB). Community strings function as passwords embedded in every SNMP packet.
SNMP Commands SNMP Trap Message Commands When the switch detects an extraordinary event, it generates a trap. A trap is a notification message that may be sent to predefined network manager stations. A trap event may be a reset (cold or warm), detection of a interface link status change, an SNMP authentication failure due to an incorrect community string, etc.
SNMP Commands SYS_console> add-trap 129.1.1.76 rnd Entry 129.1.1.76 - rnd added SNMP TRAP TABLE =============== IPADDR COMMUNITY ------------------------------------------129.001.001.065 ----public 129.001.001.007 ----trapcomm 129.001.001.076 ----rnd ------------------------------------------- del-trap Usage: del-trap The del-trap command can be used to remove a station from the trap table. The station IP address must be provided. SYS_console> del-trap 129.1.1.7 Entry 129.1.1.
Switching Database Commands Switching Database Commands This section contains instructions for managing the switching database with the Administrative Interface. The switching database consists of 4096 entries. Each active entry contains the information relevant to an end station, characterized by its Ethernet MAC address. Each entry contains the following information: • lock If on (denoted as a +), the entry will not be deleted by the switch aging process (static entry).
Switching Database Commands SYS_console> get-lt-entry 19 Entry ---- MAC Address ---- LOCK SELF DPORT MGMT ============================================================== 19 00-00-F8-00-59-E6 8 SYS_console> The entry described is: • Entry number 19 • MAC address 00-00-F8-00-59-E6 • Not a static entry (it will be aged out. Lock is off.) • Is not a system address (Self is off.) • The frame will be forwarded only to the port 8 • Not forwarded to the management (Mgmt is off.
Switching Database Commands SYS_console> get-lt-16 * Entry ---- MAC Address ---- LOCK SELF DPORT MGMT ============================================================== 26 00-00-F8-11-06-AD 12 27 00-00-F8-2B-59-EA 3 28 00-00-F8-2D-99-3A 7 29 00-00-F8-16-80-7C 5 30 00-00-C0-60-A7-B9 5 31 00-00-F8-1A-A1-69 5 32 00-00-F8-29-1E-EB 11 33 00-00-F8-2E-DF-15 5 34 00-00-F8-28-B4-1A 7 35 00-00-F8-2F-93-A7 4 36 00-40-33-32-A6-58 12 37 00-00-F8-15-70-5E 5 38 00-00-F8-1A-A1-5F 11 39 00-00-F8-28-B7-2A 5 40 00-00-F8-2B-16-3D
Switching Database Commands If the requested MAC address is not in the learn table, an error message is displayed: SYS_console> find-lt-addr 00-00-F8-2b-59-66 MAC Address - 00-00-F8-2b-59-66 - not in LT SYS_console> _ del-lt-entry Usage: del-lt-entry Deletes the learn table entry at the specified index. If the entry deletion was successful or if the entry is not ACTIVE, then the command will be successful. Deleting entries with the self field set is prohibited since they are system addresses.
Switching Database Commands add-lt-addr Usage: add-lt-entry {lock-off|lock-on} Adds a learn table entry to the switching database. The command parameters are described at the beginning of this chapter. Note that dport is a decimal number representing the number of the destination port. get-lt-age Displays the switching database aging time in seconds. The aging time is the timeout period for aging out dynamically learned forwarding information entries.
Switching Database Commands Custom Filtering Commands The custom filter entry for an address is shown on the screen as a matrix, in the following format: Here, the SRC column lists the available source ports (1 through the number of ports on the switch). The other columns each represent an available destination port. If a + mark is encountered, it represents a forwarding path. For example, as displayed below, each source port (with the exception of port 3) will forward this frame to port 3.
Switching Database Commands (bit 0 is the management port, bit 1 is port 1...). Packets arriving at the switch with mac_address destination address from any port specified in sport will be transmitted to all ports specified in dport.
Switching Database Commands This command deletes the custom filter learn table entry for address mac_address from source port sport. The run option indicates that the entry will be deleted only from the current running table. The all option indicates that the entry should be removed from the non-volatile memory as well as from the current running table. get-nv-cftbl This command displays the custom filter table stored in nonvolatile memory.
Switching Database Commands get-dport-hex Usage: get-sport-hex This command displays the list of destination ports in hexadecimal. One or more port numbers may be entered for the port_number value, separated by the hyphen symbol (-).
Virtual LAN Commands Virtual LAN Commands Virtual LANs can be used to limit the broadcast domain and to establish virtual workgroups. • The run option indicates that only the currently running configuration is changed. Changes are not restored after a reset. • The nvram option indicates that only the configuration stored in nonvolatile memory is changed. Changes do not take effect until a reset.
Virtual LAN Commands get-vbc-matrix Retrieves the current broadcast domain matrix for the switch. See above for a description of the resulting table. Here, though, only the broadcast address will be affected.
Virtual LAN Commands This command retrieves the list of defined virtual broadcast domains. SYS_console> get-vbc-tbl run RUNTIME VIRTUAL BROADCAST DOMAIN TABLE =========================================== VBC ID P1 P2 P3 P4 P5 P6 P7 P8 P9 P10 P11 P12 =========================================================== 1: + + + SYS_console> set-sec-vlan Usage: set-sec-vlan {run|nvram|all} This command establishes a security virtual LAN. The arguments are identical to setvbc-domain.
Virtual LAN Commands set-mon-port Usage: set-mon-port This command sets the port to be monitored. The value port is a decimal port number. All traffic from this port will be duplicated on the monitoring port specified by the monitor command. monitor Usage: monitor This command sets the monitoring port. All traffic from the port specified by set-monport will be duplicated on port. The value port is a decimal port number. stop-mon This command ends port monitoring.
Spanning Tree Commands Spanning Tree Commands Spanning Tree automatically configures a loop-free topology in a bridged environment. The Spanning Tree agent is implemented in conformance to the IEEE 802.1d standard. Below are listed the configuration commands pertinent to the operation of the Spanning Tree algorithm. get-stp Retrieves the current state of Spanning Tree. Either enable or disable. set-stp Usage: set-stp {enable|disable} This command enables or disables the Spanning Tree protocol.
Spanning Tree Commands set-br-maxage Usage: set-br-maxage This command sets the Spanning Tree bridge MaxAge. This is the amount of time between Spanning Tree configuration messages. Note that maxage is in units of seconds in the range 6...40, while the corresponding MIB variable, dot1dStpBridgeMaxAge (RFC 1493), is in units of hundreths of a second, in the range 600...4000, and must be a multiple of 100.
Spanning Tree Commands set-prt-enb Usage: set-prt-enb {enable|disable} This command enables or disables a port in the Spanning Tree. The port_number value is the integer port number. This is equivalent to setting the MIB variable dot1dStpPortEnable (RFC 1493). set-prt-pcost Usage: set-prt-pcost This command sets the Spanning Tree port path cost. The port_number value is the integer port number, and the path_cost value is an integer path cost in the range 1...
Port Configuration Commands Port Configuration Commands This section contains instructions for configuring and displaying the ports’ parameters with the Administrative Interface. get-port-cfg The get-port-cfg command displays the current port configuration.
Port Configuration Commands set-port-dplex Usage: set-port-dplex {half|full} The set-port-dplex command specifies if the given port will be active in full-duplex or in half-duplex (standard Ethernet) mode. The default is half-duplex mode. SYS_console> set-port-dplex 2 full Port configured in mode Parameter change in NVRAM OK SYS_console> _ NOTE The 10 Mb/s, full-duplex, and flow control options are mutually exclusive.
Port Configuration Commands If the port is in full-duplex mode, the status of the flow control option has no effect, unless the connection is 100 Mb/s and both ports are on MultiSwitch 300s.
Switching Statistics Commands Switching Statistics Commands This section contains instructions for displaying the switching statistics using the Administrative Interface. The following commands provide full physical layer information as well as inter-port switching statistics. clr-cnt This command clears the Ethernet and bridging counters. get-eth-cnt Usage: get-eth-cnt This command displays the Ethernet statistics counters for the specified port number.

Chapter 8 Using an SNMP Manager Overview This chapter contains instructions regarding the configuration and management of the MultiSwitch 300 with an SNMP management system. The MultiSwitch 300 with an SNMP Agent board installed is a plug and play device. Once connected to the network and powered ON, the MultiSwitch 300 starts operating according to factory set default values.
Check that the actual IP configuration matches the desired one: SYS_console> get-ip-cfg The device IP address, netmask and broadcast are: IP address : 129.001.001.064 IP netmask : 255.255.255.000 IP broadcast : 129.001.001.255 2) Set the default gateway address using the set-gatew command (For more details, see Chapter 7, IP Commands.) This should be a station that can route IP packets to non-local IP networks. For example: SYS_console> set-gatew 129.1.1.
Chapter 9 Troubleshooting the SNMP Manager Procedure for Troubleshooting This chapter provides troubleshooting hints for problems you may encounter when trying to manage the MultiSwitch 300 using an SNMP management system. • If your SNMP manager has trouble communicating with the SNMP Agent in the switch, check your SNMP configuration parameters. Your Network Administrator can help determine if your IP configuration (IP address. netmask, and broadcast address) is correct.
