Using straight cable When using straight cable, this is done from the uplink (MDI-II) port of the Switch (Switch A) to any of the 10 Mbps or 100 Mbps (MDI-X) port of the other switch (switch B) or other devices (see figure 4-4).
10/100 Fast Ethernet Switch User’s Guide 5 5 S WITCH MANAGEMENT Local Console Managament Local console management involves the administration of the DES-3208 Switch via a direct connection to the RS-232 DCE console port. From the Main Menu screen of the console program, a Super User or General User (defined in the next chapter) has priviledge and access to manage, control and monitor the many functions of the Switch. The components of the Switch allow them to be part of a manageable network.
10/100 Fast Ethernet Switch User’s Guide Console port (RS-232 DCE Out-of-band )management requires connecting a PC (with a SNMP management platform) to the RS-232 DCE console port of the Switch. Switch management using terminal emulation/ VT100 when connected to the RS-232 DCE console port is called Local Console Managment to differentiate it from management done via management platforms.
10/100 Fast Ethernet Switch User’s Guide Traps Trap managers are special users of the network who are given certain rights and access in overseeing the maintenance of the network. Trap managers can receive traps sent from the Switch; they must immediately take certain actions to avoid future failure or breakdown of the network. Traps are messages that alert you of events that occur on the Switch.
10/100 Fast Ethernet Switch User’s Guide election as the new root. This implies that upon expiration of the Topology Change Timer the new root trap is sent out immediately after the Switch’s selection as a new root. ♦ Topology Change: A Topology Change trap is sent by the Switch when any of its configured ports tranisitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a new root trap is sent for the same transition.
10/100 Fast Ethernet Switch User’s Guide Read-write MIBs are variables usually related to user-customized configurations. Examples of these are the Switch’s IP Address, Spanning Tree Algorithm parameters and port status. If you use a third-party vendors’ SNMP software to manage the Switch, a diskette listing the Switch’s propriety enterprise MIBs can be obtained by request.
10/100 Fast Ethernet Switch User’s Guide 5. Calculation and configuration of Switched Local Area Network topology. Aging Time The Aging Time is a parameter that affects the auto-learn process of the Switch in terms of the network configuration. Dynamic Entries, which make up the auto-learned-node address, are aged out of the address table according to the Aging Time that you set. The Aging Time can be from 10 seconds to 1,000,000 seconds.
10/100 Fast Ethernet Switch User’s Guide cost as the active path, while blocking the other path and using it as the backup path. ♦ Automatic topology re-configuration. When the path for which there is a backup path fails, the backup path will be automatically activated, and STA will automatically reconfigure the network topology. STA Operation Levels STA operates on two levels: the bridge level and the port level.
10/100 Fast Ethernet Switch User’s Guide ♦ Root Path Cost: The Root Path Cost of a Switch is the sum of the Path Cost of the Root Port and the Root Path Costs of all the Switches that the packet goes through. The Root Path Cost of the Root Bridge is zero. ♦ Bridge Priority: This is a parameter that users can set. The smaller the number you set, the higher the Bridge Priority is. the higher the Bridge Priority, the better the chance the Switch will be selected as the Root Bridge.
10/100 Fast Ethernet Switch User’s Guide ♦ Bridge Priority. A Bridge Priority can be from 0 to 65535. 0 is equal to the highest Bridge Priority. ♦ Bridge Hello Time. The Hello Time can be from 1 to 10 seconds. This is the interval between two transmissions of BPDU packets sent by the Root Bridge to tell all other Switches that it is indeed the Root Bridge. If you set a Hello Time for your Switch, and it is not the Root Bridge, the set Hello Time will be used if and when your Switch becomes the Root Bridge.
10/100 Fast Ethernet Switch User’s Guide Illustration of STA A simple illustration of three Bridges (or the Switch) connected in a loop is depicted in Figure 5-1. In this example, you can anticipate some major network problems if the STA assistance is not applied. For instance, if Bridge 1 broadcasts a packet to Bridge 2, Bridge 2 will broadcast it to Bridge 3, and Bridge 3 will broadcast it to Bridge 1...and so on.

10/100 Fast Ethernet Switch User’s Guide STA parameters Settings Effects Comment Bridge Priority lower the #, higher the priority Increases chance of becoming the Root Bridge Avoid, if the switch is used in workgroup level of a large network Hello Time 1 - 10 sec. No effect, if not Root Bridge Never set greater than Max. Age Time Max. Age Time 6 - 40 sec. Compete for Root Bridge, if BPDU is not received Avoid low number for unnecessary reset of Root Bridge Forward Delay 4 - 30 sec.
10/100 Fast Ethernet Switch User’s Guide 6 6 U SING THE C ONSOLE I NTERFACE Your 10/100 Fast Ethernet Switch supports a console management interface that allows you to set up and control your Switch, either with an ordinary terminal (or terminal emulator), or over the network using the TCP/IP TELNET protocol. You can use this facility to perform many basic network management functions.
10/100 Fast Ethernet Switch User’s Guide ♦ 9,600 baud ♦ 8 data bits ♦ No parity ♦ One stop bit You can also access the same functions over a TELNET interface. Once you have set an IP address for your Switch, you can use a TELNET program (in a VT-100 compatible terminal mode) to access and control the Switch. All of the screens are for the most part identical, whether accessed from the console port or from a TELNET interface.
10/100 Fast Ethernet Switch User’s Guide First Time Connecting To The Switch The Switch supports user-based security that can allow you to prevent unauthorized users from accessing the Switch or changing its settings. This section tells how to log onto the Switch.

For a detail list of Trap Types used for this Switch, see Chapter 5, Switch Management, Traps section. Figure 6-14. SNMP Trap Manager Configuration Menu The following trap parameters can be set: ♦ IP Address: gives the IP address of the network management station to receive the trap.
10/100 Fast Ethernet Switch User’s Guide SNMP Manager Configuration SNMP Security (Community Names) SNMP (version 1) implements a rudimentary form of security by requiring that each request includes a community name. A community name is an arbitrary string of characters used as a “ password” to control access to the Switch. If the Switch receives a request with a community name it does not recognize, it will trigger an authentication trap. The SNMP allows up to four different community names to be defined.
10/100 Fast Ethernet Switch User’s Guide Port Configuration The port configuration menu allows you to change the port state in the case when you would like to partition a port due to excessive collision, or for observation, device repair, security reasons. Great caution, however, must be observed when partitioning a port; you should make sure that the partitioned port is not being used as the port to control or monitor the condition of other devices. To change the configuration of a port: 1.
10/100 Fast Ethernet Switch User’s Guide Previously made modifications should be noticed the next time upon entering the Port Configuration menu. You can use the PREPORT and NEXTPORT commands to view and modify the previous port and next port, respectively, as you wish. Switch Monitoring The Switch allows you to keep statistics on the operation of each port. The statistics obtained can be used to monitor the conditions and general efficiency of the Switch.
