An in-band connection between the switch and the TFTP load host is required to download the software image. If a BootP server is set up properly on the network and the BayStack 450 switch detects a corrupted software image during the self-test, the switch automatically uses TFTP to download a new software image.
800 Mb/s in full-duplex mode. BayStack 450 switches can be configured with up to six MultiLink Trunks. The trunk members can be configured within a single unit in the stack or distributed between any of the units within the stack configuration (distributed trunking).
“Autonegotiation Modes” on page 4-8. BootP Automatic IP Configuration/MAC Address The BayStack 450 switch has a unique 48-bit hardware address, or MAC address, that is printed on a label on the back panel.

Note: All models of the BayStack 450 switch can be used interchangeably in the following network configuration examples. Desktop Switch Application Figure 1-6 shows a BayStack 450-24T switch used as a desktop switch, where desktop workstations are connected directly to switch ports.
Segment Switch Application Figure 1-7 shows a BayStack 450-24T switch used as a segment switch to alleviate user contention for bandwidth and eliminate server and network bottlenecks. Before segmentation, 88 users had a total bandwidth of only 10 Mb/s available. After segmentation, 92 users have 40 Mb/s, four times the previous bandwidth, while adding 22 dedicated 100 Mb/s connections.
BayStack 450 switch with an optional gigabit (1000BASE-SX) MDA for maximum bandwidth. The BayStack 303 and 304 switches have 100 Mb/s connections to the BayStack 450 switch, a 100BASE-TX hub, and a 100 Mb/s server and 10 Mb/s connections to DTE (data terminal equipment).
Fail-Safe Stack Application Figure 1-9 shows an example of eight BayStack 450 switches that are stacked together as a single managed unit. If any single unit in the stack fails, the remaining stack remains operational, without interruption. As shown in connecting to the BayStack 450 switch with an optional gigabit (1000BASE-SX) MDA for maximum bandwidth.
BayStack 450 switches that are configured with BayStack 450 software versions earlier than version V1.1.0. If you need to upgrade your BayStack 450 switches, refer to the upgrade instructions provided in the Installing the BayStack 400-ST1 Cascade Module guide. You must upgrade the switch before installing the BayStack 400-ST1 Cascade Module.
The Unit Select switch (up = Base) determines the base unit for the stack configuration (see displayed on the BayStack 450 LED display panel. When the Unit Select switch is in the Base (up) position, all other Unit Select switches in the stack configuration must be set to Off (down).
The base unit is the unique stack unit that you configure with the Unit Select switch on the front panel of the 400-ST1 cascade module. One unit 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...
For this reason, you should always assign the temporary base unit as the base unit (set the Unit Select switch to Base) until the failed unit is repaired or replaced.
As shown in panel provide the ability to stack up to eight BayStack switches. With 400-4TX MDAs installed in each switch, the stack can accommodate a maximum of 224 switch ports. Because stack parameters are associated with the base unit (see page 1-25), the physical stack order depends on the base unit’s position and...
1-12, data flows from the base unit (unit 1) to the next switch, which is assigned as unit 2, and continues until the last switch in the stack is assigned as unit 8. The physical order of the switches is from bottom to top (unit 1 to unit 8).

VLAN, it is added to a group of ports (workgroup) that belong to one broadcast domain. The BayStack 450 switch allows you to assign ports to VLANs using the console or TELNET; VLAN assignment is not currently available through SNMP. You can assign different ports (and therefore the devices attached to these ports) to different broadcast domains.
IEEE 802.1Q Tagging BayStack 450 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.
Page 60
• Filtering database identifier (FID) -- the specific filtering/forwarding database within the BayStack 450 switch that is assigned to each VLAN. The current version of software assigns all VLANs to the same FID. This is referred to as Shared VLAN Learning in the IEEE 802.1Q specification.
Page 61
802.1Q Tagging (1 of 4) As shown in switch through port 5, which is configured as a tagged member of VLAN 2. The untagged packet remains unchanged as it leaves the switch through port 7, which is configured as an untagged member of VLAN 2.
Page 62
802.1Q Tagging (3 of 4) As shown in switch through port 5, which is configured as a tagged member of VLAN 2. However, the tagged packet is stripped (untagged) as it leaves the switch through port 7, which is configured as an untagged member of VLAN 2.
VLANS Spanning Multiple Untagged Switches Figure 1-22 configuration switch S2 does not support 802.1Q tagging and you must use a single switch port on each switch for each VLAN. For this configuration to work properly, you must set spanning tree participation to Disabled (the STP is not supported across multiple LANs).
Page 65
Because the other link connecting VLAN 2 is in Blocking mode, stations on VLAN 2 in switch S1 cannot communicate with stations in VLAN 2 on switch S2. With multiple links only one link will be forwarding.
Shared Servers BayStack 450 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 1-24.

To configure the port priority level, follow these steps: Determine the priority level you want to assign to the switch port. User priority levels are assigned default settings in all BayStack 450 switches. The range is from 0 to 7. The traffic class table can be modified; therefore, view the settings shown in the Traffic Class Configuration screen before setting the port priority in the VLAN Port Configuration screen.
Select a priority level from the range shown in the Traffic Class Configuration screen (or modify the Traffic Class parameters to suit your needs). Assign the priority level to ports using the VLAN Port Configuration screen: Press [Ctrl]-R to return to the VLAN Configuration Menu. From the VLAN Configuration Menu, select VLAN Port Configuration (or press c).
MultiLink Trunks MultiLink Trunks allow you to group up to four switch ports together to form a link to another switch or server, thus increasing aggregate throughput of the interconnection between the devices (up to 800 Mb/s in full-duplex mode). You can configure up to six MultiLink Trunks.
Client/Server Configuration Using MultiLink Trunks Figure 1-40 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). 1-58 shows a typical switch-to-server trunk configuration. In this example,...
Page 85
Clients accessing data from the servers (FS1 and FS2) are provided with maximized bandwidth through trunks T1, T2, T3, T4, and T5. Trunk members (the ports making up each trunk) do not have to be consecutive switch ports; you can select ports randomly, as shown by T5.

Page 94
Switch S4 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 5 and 11 are assigned as trunk members of trunk T1.
Before Configuring 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. Before configuring your MultiLink Trunk, you must consider these settings, along with specific configuration rules, as follows:...
Page 96
• All trunk members must have the same VLAN configuration before the Trunk Configuration screen’s Trunk Status field can be set to Enabled (see “VLAN Configuration” on page 3-24). • When an active port is configured in a trunk, the port becomes a trunk member when you set the Trunk Status field to Enabled.

Spanning Tree Considerations for MultiLink Trunks The spanning tree Path Cost parameter is recalculated based on the aggregate bandwidth of the trunk. For example, 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).
Page 99
The switch can also detect trunk member ports that are physically misconfigured. For example, in 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.
Using the BayStack 450 10/100/1000 Series Switch 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 1-49).
BayStack 450 10/100/1000 Series Switches 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.
Note: A probe device, such as the Nortel Networks StackProbe equivalent, must be connected to the designated monitor port to use this feature (contact your Nortel Networks sales agent for details about the StackProbe). The following sections provide sample configurations for both monitoring modes available with the Port Mirroring feature: •...
23 is designated as the monitor port for ports 24 and 25 of switch S1. Although this example shows ports 24 and 25 monitored by the monitor port (port 23), any of the trunk members of T1 and T2 can also be monitored.
Page 104
• As shown in the Port Mirroring Configuration screen example port 23 is designated as the Monitor Port for ports 24 and 25 in switch S1. Note: The Unit value (in the Unit/Port field) is not configurable when the switch is operating standalone.

ID (Renumber Stack Unit table full). The unit is on the ring but cannot participate in the stack configuration. The switch is configured as the stack base unit. The switch is not configured as the stack base unit (or is in standalone mode). Blinking Stack configuration error: indicates that multiple base units or no base units are configured in the stack.
Diagnosing and Correcting the Problem Before you perform the problem-solving steps in this section, cycle the power to the BayStack 450 switch (disconnect and then reconnect the AC power cord); then, verify that the switch follows the normal power-up sequence.
Normal Power-Up Sequence In a normal power-up sequence, the LEDs appear as follows: After power is applied to the switch, the Pwr (Power) LED turns on within 5 seconds. The switch initiates a self-test, during which the port LEDs display various patterns to indicate the progress of the self-test.
Note: Operating temperature for the switch must not exceed 40°C (104°F). Do not place the switch in areas where it can be exposed to direct sunlight or near warm air exhausts or heaters.
• If the autonegotiation feature is not present or not enabled at the connected station, the BayStack 450 switch may not be able to determine the correct duplex mode. In both situations, the BayStack 450 switch “autosenses” the speed of the connected station and, by default, reverts to half-duplex mode.
Note: Nortel Networks recommends that you manually set the BayStack 450 switch port to the desired speed/duplex mode when connecting to any of the following Nortel Networks products: • Nortel Networks 28000 product family • Nortel Networks 58000 product family •...
