Chapter 1 BayStack 420 Switch 25 Chapter 1 BayStack 420 Switch This chapter introduces the BayStack 420 Switch and covers the following topics: • • “Physical description,” next “Features” on page 34 Physical description Figure 1 depicts the front and side views of the BayStack 420 Switch.
Chapter 1 BayStack 420 Switch Front panel Figure 2 shows the configuration of the front panel on the BayStack 420 Switch. Table 1 describes the components on the front panel. For descriptions of the back panel BayStack 420 Switch components, see “Back panel” on page 30.
Chapter 1 BayStack 420 Switch 27 The Console port is a DB-9, RS-232-D male serial port connector. You can use this connector to connect a management station or console/terminal to the BayStack 420 Switch by using a straight-through DB-9 to DB-9 standard serial port cable. You must use a VT100/ANSI-compatible terminal (for cursor control and to enable cursor and functions keys) to use the console port. See Installing the BayStack 420 10/100/1000 Switch for more information.
Chapter 1 BayStack 420 Switch The 10BASE-T/100BASE-TX switch ports also support half- and full-duplex mode operation (refer to Installing the BayStack 420 10/100/1000 Switch). The 10BASE-T/100BASE-TX RJ-45 ports can connect to 10 Mb/s or 100 Mb/s Ethernet segments or nodes. Note: Use only Category 5 copper unshielded twisted pair (UTP) cable connections when connecting 10BASE-T/100BASE-TX ports.

Chapter 1 BayStack 420 Switch Back panel The switch back panel is shown in Figure 4. Table 3 describes the components on the back panel.
Chapter 1 BayStack 420 Switch 31 AC power receptacle The AC power receptacle accepts the AC power cord (supplied). For installation outside of North America, make sure that you have the proper power cord for your region. Any cord used must have a CEE-22 standard V female connector on one end and must meet the IEC 320-030 specifications. Table 4 lists specifications for international power cords.
Chapter 1 BayStack 420 Switch Caution: Please read immediately. Inspect this power cord and determine if it provides the proper plug and is appropriately certified for use with your electrical system. Immediately discard this cord if it is inappropriate for your country’s electrical system and obtain the proper cord as required by your national electrical codes or ordinances.
Chapter 1 BayStack 420 Switch 33 Advertencia: Sírvase leer inmediatamente. Inspeccione este cable de alimentación eléctrica y determine si viene con el enchufe apropiado y está debidamente certificado para el uso con su sistema eléctrico. Si no cumple con los reglamentos del sistema eléctrico de su país, despójese de este cable de alimentación inmediatamente y obtenga el cable requerido, según las ordenanzas y códigos eléctricos nacionales.
Chapter 1 BayStack 420 Switch Avvertenza: Estrarre il cavo di alimentazione è l'unico sistema per spegnere il dispositivo. Il cavo di alimentazione deve essere sempre collegato in una posizione che permetta l'accesso facile e sicuro in caso di emergenza. Features The BayStack 420 Switch provides wire-speed switching that allows high-performance, low-cost connections to full-duplex and half-duplex 10/100/1000 Mb/s Ethernet local area networks (LANs).
Chapter 1 BayStack 420 Switch 35 Security The BayStack 420 Switch security features provide two levels of security for your local area network (LAN): • • RADIUS-based security—limits administrative access to the switch through user authentication MAC address-based security—limits access to the switch based on allowed source MAC addresses Figure 5 shows a typical campus configuration using the BayStack 420 Switch security features.
Chapter 1 BayStack 420 Switch In this configuration example, the following security measures are implemented: • • The switch — RADIUS-based security is used to limit administrative access to the switch through user authentication (see “RADIUS-based network security” on page 37). — MAC address-based security is used to allow up to 448 authorized stations (MAC addresses) access to one or more switch ports (see “MAC address-based security” on page 37).
Chapter 1 BayStack 420 Switch 37 RADIUS-based network security The RADIUS-based security feature allows you to set up network access control, using the RADIUS (Remote Authentication Dial-In User Services) security protocol. The RADIUS-based security feature uses the RADIUS protocol to authenticate local console and Telnet logins. You will need to set up specific user accounts (user names and passwords, and Service-Type attributes) on your RADIUS server before the authentication process can be initiated.
Chapter 1 BayStack 420 Switch The response can be to send a trap, turn on destination address (DA) filtering, disable the specific port, or any combination of these three options. The MAC address-based security feature is based on Nortel Networks BaySecure LAN Access for Ethernet, a real-time security system that safeguards Ethernet networks from unauthorized surveillance and intrusion.
Chapter 1 BayStack 420 Switch 39 MultiLink Trunking The MultiLink Trunking feature allows you to group multiple ports, two to four together, when forming a link to another switch or server, thus increasing aggregate throughput of the interconnection between two devices, up to 800 Mb/s in full-duplex mode. The BayStack 420 Switch can be configured with up to six MultiLink Trunks in a stack. The trunk members can only be configured within a single unit in the stack.
Chapter 1 BayStack 420 Switch Autosensing is used when the attached device is not capable of autonegotiation or is using a form of autonegotiation that is not compatible with the IEEE 802.3u autonegotiation standard. In this case, because it is not possible to sense the duplex mode of the attached device, the BayStack 420 Switch reverts to half-duplex mode.
Chapter 1 BayStack 420 Switch 41 SNMP MIB support The BayStack 420 Switch supports an SNMP agent with industry standard MIBs, as well as private MIB extensions, which ensures compatibility with existing network management tools. The switch supports the MIB-II (RFC 1213), Bridge MIB (RFC 1493), and the RMON MIB (RFC 1757), which provide access to detailed management statistics.
Chapter 1 BayStack 420 Switch SNMP trap support The BayStack 420 Switch supports an SNMP agent with industry standard SNMPv1 traps, as well as private SNMPv1 trap extensions (Table 6). Table 6 Support SNMP traps Trap name Configurable Sent when linkUp Per port A port’s link state changes to up. linkDown Per port A port’s link state changes to down. authenticationFailure System wide There is an SNMP authentication failure. coldStart Always on The system is powered on.
Chapter 1 BayStack 420 Switch 43 Configuration and switch management The BayStack 420 Switch is shipped directly from the factory ready to operate in any 10BASE-T or 100BASE-TX standard network. You must assign an IP address to the switch or stack, depending on the mode of operation. You can set both addresses by using the console port or BootP, which resides on the switch.
Chapter 1 BayStack 420 Switch Optivity network management software consists of views, most of which are maps that illustrate the interconnections between the segments, rings, and nodes of your network. The views allow you to analyze network performance and fault conditions on the individual segments and specific areas in your network. They can also alert you when a problem has occurred in a specific location. For further information about Optivity, contact your Nortel Networks sales representative.
Chapter 2 Network configuration Use BayStack 420 switches to connect workstations, personal computers (PCs), and servers to each other by connecting these devices directly to the switch, through a shared media hub connected to the switch or by creating a virtual LAN (VLAN) through the switch. This chapter describes the following topics: • • • • • “Network configuration examples,” next “BayStack 420 Switch stack operation” on page 49 “IEEE 802.

The entire stack is manageable as a single unit.
Chapter 2 Network configuration Base unit The base unit is the unique stack unit that you configure with the Unit Select switch on the front panel. One BayStack 420 Switch in the stack must be configured as the base unit; all other units in the stack must have their Unit Select switch set to Off (see “Unit select switch” on page 49). You can assign any single BayStack 420 Switch as the base unit.
Chapter 2 Network configuration 51 If another unit in the stack is assigned as the base unit, the MAC address of the new base unit (with offset) now applies to the stack configuration. The original stack IP address still applies to the new base unit.

Chapter 2 Network configuration In any stack configuration, the following applies: • • • • • When you apply power to the stack, the base unit initializes and the entire stack powers up as a single logical unit. You can attach an RS-232 communications cable to the console port of any switch in the stack.
Chapter 2 Network configuration 55 Figure 11 Port-based VLAN example VLAN 1 VLAN 2 BayStack 420 10004EA IEEE 802.1Q tagging BayStack 420 switches operate in accordance with the IEEE 802.1Q tagging rules. Important terms used with the 802.1Q tagging feature are: • • • • • VLAN identifier (VID)—the 12-bit portion of the VLAN tag in the frame header that identifies an explicit VLAN.
Chapter 2 Network configuration • • • • • Untagged member—a port that has been configured as an untagged member of a specific VLAN. When an untagged frame exits the switch through an untagged member port, the frame header remains unchanged. When a tagged frame exits the switch through an untagged member port, the tag is stripped and the tagged frame is changed to an untagged frame. Tagged member—a port that has been configured as a member of a specific VLAN.

Chapter 2 Network configuration 59 In Figure 15, tagged incoming packets are assigned directly to VLAN 2 because of the tag assignment in the packet. Port 5 is configured as a tagged member of VLAN 2, and port 7 is configured as an untagged member of VLAN 2. Figure 15 802.1Q tag assignment Data Tag SA Port 4 CRC DA Before Port 2 Port 3 Tagged member of VLAN 2 Port 5 Port 1 PVID = 2 Tagged packet 802.
Chapter 2 Network configuration VLANs spanning multiple switches You can use VLANs to segment a network within a switch. When you connect multiple switches, it is possible to connect users of one VLAN with users of that same VLAN in another switch. However, the configuration guidelines depend on whether both switches support 802.1Q tagging. With 802.1Q tagging enabled on a port for a VLAN, all frames leaving the port for that VLAN are marked as belonging to that specific VLAN.
Chapter 2 Network configuration 61 Because there is only one link between the two switches, the Spanning Tree Protocol (STP) treats this configuration as any other switch-to-switch connection. For this configuration to work properly, both switches must support the 802.1Q tagging protocol. VLANS spanning multiple untagged switches Figure 18 shows VLANs spanning multiple untagged switches. In this configuration, Switch S2 does not support 802.
Chapter 2 Network configuration To connect multiple VLANs across switches with redundant links, you must disable the STP on all participating switch ports. Figure 19 shows possible consequences of enabling the STP when using VLANs between untagged (non-802.1Q tagged) switches.
Chapter 2 Network configuration 63 Shared servers BayStack 420 switches allow ports to exist in multiple VLANs for shared resources, such as servers, printers, and switch-to-switch connections. It is also possible to have resources exist in multiple VLANs on one switch as shown in Figure 20. In this example, clients on different broadcast domains share resources. The broadcasts from ports configured in VLAN 3 can be seen by all VLAN port members of VLAN 3.
Chapter 2 Network configuration Figure 21 VLAN broadcast domains within the switch S1 VLAN 3 VLAN 2 Port 2 Port 4 Port 10 PVID = 2 VLAN 1 Port 8 PVID = 3 V2 V2 V2 V3 Port 6 Port 11 PVID = 1 V1 V2 Key VLAN 1 (PVID = 1) VLAN 2 (PVID = 2) VLAN 3 (PVID = 3) BS45019A For example, to create a broadcast domain for each VLAN shown in Figure 21, configure each VLAN with a port membership, and each port with the appropriate PVID/VLAN association: • • • • • • Ports 8, 6, and 11 are untagged membe
Chapter 2 Network configuration 65 To configure the VLAN port membership for VLAN 1: 1 Select Switch Configuration from the BayStack 420 Switch Main Menu (or press w). 2 From the Switch Configuration Menu, select VLAN Configuration (or press v). 3 From the VLAN Configuration Menu select VLAN Configuration (or press v). The default VLAN Configuration screen opens (Figure 22).
Chapter 2 Network configuration Ports 2, 4, 6, 8, 10, and 11 are now untagged members of VLAN 3 as shown in Figure 21 on page 64. Figure 23 VLAN Configuration screen example To configure the PVID (port VLAN identifier) for port 8: 1 From the VLAN Configuration screen, press [Ctrl]-R to return to the VLAN Configuration Menu. 2 From the VLAN Configuration Menu, select VLAN Port Configuration (or press c). The default VLAN Port Configuration screen opens (Figure 24).
Chapter 2 Network configuration 67 Figure 24 Default VLAN Port Configuration screen example Figure 25 shows the VLAN Port Configuration screen after it is configured to support the PVID assignment for port 8, as shown in Figure 21 on page 64 (Port Name is optional). The PVID/VLAN association for VLAN 3 is now PVID = 3.
Chapter 2 Network configuration Figure 25 VLAN Port Configuration screen example VLAN workgroup summary This section summarizes the VLAN workgroup examples discussed in the previous sections of this chapter. As shown in Figure 26, Switch S1 (BayStack 420 Switch) is configured with multiple VLANs: • • • Ports 1, 6, 11, and 12 are in VLAN 1. Ports 2, 3, 4, 7, and 10 are in VLAN 2. Port 8 is in VLAN 3. Because S4 does not support 802.

Chapter 2 Network configuration VLAN configuration rules VLANs operate according to specific configuration rules. When creating VLANs, consider the following rules that determine how the configured VLAN reacts in any network topology: • • • • All ports that are involved in port mirroring must have memberships in the same VLANs. If a port is configured for port mirroring, the port’s VLAN membership cannot be changed.
Chapter 2 Network configuration 71 Figure 27 Switch-to-switch trunk configuration example BayStack 420 S1 T1 F BayStack 420 S2 T2 BayStack 420 S3 10009EA You can configure each of the trunks shown in Figure 27 with up to four switch ports to provide up to 800 Mb/s aggregate bandwidth through each trunk, in full-duplex mode.
Chapter 2 Network configuration Figure 28 Switch-to-server trunk configuration example FS1 FS2 T1 S1 BayStack 420 10010EA Client/server configuration using MultiLink Trunks Figure 29 shows an example of how MultiLink Trunking can be used in a client/server configuration. In this example, both servers connect directly to Switch S1. FS2 is connected through a trunk configuration (T1). The switch-to-switch connections are through trunks (T2, T3, T4, and T5).
Chapter 2 Network configuration 73 Figure 29 Client/server configuration example FS2 FS1 T1 BayStack 420 S1 F T2 T3 S2 BayStack 420 T4 S3 T5 BayStack 420 S4 BayStack 420 10011EA The trunk configuration screens for switches S1 to S4 are shown in “Trunk configuration screen examples” following this section. For detailed information about configuring trunks, see “MultiLink Trunk Configuration screen” on page 135.
Chapter 2 Network configuration Trunk configuration screen for Switch S1 Switch S1 is set up with five trunk configurations: T1, T2, T3, T4, and T5. To set up the S1 trunk configuration: Choose MultiLink Trunk Configuration (or press t) from the MultiLink Trunk Configuration Menu screen (Figure 30). Figure 30 Choosing the MultiLink Trunk Configuration Menu screen The MultiLink Trunk Configuration Menu screen opens (Figure 31).
Chapter 2 Network configuration 75 Figure 31 MultiLink Trunk Configuration screen for Switch S1 Switch S1 is configured as follows: • • Trunk (read only) indicates the trunks (1 to 6) that correspond to the switch ports specified in the Trunk Members fields. Trunk Members (Unit/Port) indicates the ports that can be configured, in each row, to create the corresponding trunk: Note: The Unit value (in the Unit/Port field) is not configurable when the switch is operating standalone.
Chapter 2 Network configuration • • — Ports 15, 17, 19, and 21 are assigned as trunk members of trunk 1. — Ports 25 and 26 are assigned as trunk members of trunk 2. — Ports 2 and 4 are assigned as trunk members of trunk 3. — Ports 14 and 16 are assigned as trunk members of trunk 4. — Ports 22 and 24 are assigned as trunk members of trunk 5. STP Learning indicates the spanning tree participation setting for each of the trunks: — Trunks 1 through 4 are enabled for Normal STP Learning.
Chapter 2 Network configuration 77 Figure 32 shows the MultiLink Trunk Configuration screen for Switch S2. Figure 32 MultiLink Trunk Configuration screen for Switch S2 Switch S2 is configured as follows: • • • • • Trunk (read only) indicates the trunks (1 to 6) that correspond to the switch ports specified in the Trunk Members fields.
Chapter 2 Network configuration • Trunk Name indicates optional fields for assigning names to the corresponding configured trunks. The names chosen for this example provide meaningful information to the user of this switch (for example, S2:T2 to S1 indicates that Trunk 1, in Switch S2, connects to Switch 1). Trunk Configuration screen for Switch S3 As shown in Figure 29 on page 73, Switch S3 is set up with one trunk configuration (T4). This trunk connects directly to Switch S1.
Chapter 2 Network configuration 79 Switch S3 is configured as follows: • • • • • • Trunk (read only) indicates the trunk (1 to 6) that corresponds to the switch ports specified in the Trunk Members fields. Trunk Members (Unit/Port) indicates the ports that can be configured, in each row, to create the corresponding trunk. Ports 1 and 3 are assigned as trunk members of trunk 1. STP Learning indicates the spanning tree participation setting for each of the trunks.
Chapter 2 Network configuration Figure 34 shows the MultiLink Trunk Configuration screen for Switch S4. Figure 34 MultiLink Trunk Configuration screen for Switch S4 Switch S4 is configured as follows: • • • • • • 209418-A Trunk (read only) indicates the trunk (1 to 6) that corresponds to the switch ports specified in the Trunk Members fields. Trunk Members (Unit/Port) indicates the ports that can be configured, in each row, to create the corresponding trunk.
Chapter 2 Network configuration 81 The names chosen for this example provide meaningful information to the user (for example, S4:T5 to S1 indicates that Trunk 1, in Switch S4, connects to Switch 1). Before you configure trunks When you create and enable a trunk, the trunk members (switch ports) take on certain settings necessary for correct operation of the MultiLink Trunking feature.
Chapter 2 Network configuration Spanning tree considerations for MultiLink Trunks The spanning tree Path Cost parameter is recalculated based on the aggregate bandwidth of the trunk. For example, Figure 35 shows a four-port trunk (T1) with two port members operating at 100 Mb/s and two at 10 Mb/s. Trunk T1 provides an aggregate bandwidth of 220 Mb/s. The Path Cost for T1 is 4 (Path Cost = 1000/ LAN speed, in Mb/s).
Chapter 2 Network configuration 83 The switch can also detect trunk member ports that are physically misconfigured. For example, in Figure 36, trunk member ports 2, 4, and 6 of Switch S1 are configured correctly to trunk member ports 7, 9, and 11 of Switch S2. The Spanning Tree Port Configuration screen for each switch shows the port state field for each port in the Forwarding state.
Chapter 2 Network configuration If Switch S2’s trunk member port 11 is physically disconnected and then reconnected to port 13, the Spanning Tree Port Configuration screen for Switch S1 changes to show port 6 in the Blocking state (Figure 37).
Chapter 2 Network configuration 85 Additional tips about the MultiLink Trunking feature When you create a MultiLink Trunk, the individual trunk members (the specific ports that make up the trunk) logically connect and react as a single entity. For example, if you change spanning tree parameters for any trunk member, the spanning tree parameters for all trunk members change. All configured trunks are indicated in the Spanning Tree Configuration screen.
Chapter 2 Network configuration Figure 38 provides a sample Port Mirroring Configuration screen. Note that the displayed screens do not show all of the screen prompts that precede some actions.

Chapter 4 Troubleshooting 175 Table 42 BayStack 420 Switch LED descriptions (continued) Label Type Color Activity Port activity HD/FD Duplex Mode State Meaning Green Blinking Indicates network activity for the corresponding port. A high level of network activity can cause the LEDs to appear to be on continuously. Green On/ Off The port is configured to full duplex. The port is configured to half duplex.
Chapter 4 Troubleshooting Avvertenza: Per evitare lesioni fisiche dovute a scariche pericolose di corrente, non rimuovere mai il coperchio superiore del dispositivo. I componenti interni non possono essere manipolati dall’utente. Normal power-up sequence In a normal power-up sequence, the LEDs appear as follows: 1 After power is applied to the switch, the Pwr (Power) LED turns on within 5 seconds.
Chapter 4 Troubleshooting 177 Table 43 Corrective actions (continued) Symptom Probable cause Corrective action The Activity LED for a connected port is off or does not blink (and you have reason to believe that traffic is present). The switch is experiencing a port connection problem. See “Port connection problems” next. The switch’s link partner is not autonegotiating properly.
Chapter 4 Troubleshooting In both situations, the BayStack 420 Switch “autosenses” the speed of the connected station and, by default, reverts to half-duplex mode. If the connected station is operating in full-duplex mode, it cannot communicate with the switch. To correct this mode mismatch problem: 1 Use the Port Configuration screen to disable autonegotiation for the suspect port (see “Port Configuration screen” on page 129).
