10. Select the Reload link and select Yes when the Web management interface asks you whether you really want
to reload the software.
11. If the other end of the trunk group is a switch or router, log in to the other device and follow the steps above.
NOTE: TurboIron/4 Layer 2 and Layer 3 Switches support a maximum of six ports—four standard plus two
expansion ports. Therefore, TurboIron/4 Layer 2 and Layer 3 Switches support a maximum of three trunk
groups of two ports each. The possible trunk groups are ports 1-2, 3-4 and 5-6.
Example 2: Configuring a Trunk Group That Spans Multiple Gigabit Ethernet Modules in a Chassis Device
To configure a trunk group that spans two modules in a BigIron Chassis device, use one of the following methods.
USING THE CLI
To configure a trunk group consisting of two groups of ports, 1/1 – 1/4 on module 1 and 4/5 – 4/8 on module 4,
enter the following commands:
BigIron(config)# trunk ethernet 1/1 to 1/4 ethernet 4/5 to 4/8
BigIron(config)# write memory
BigIron(config)# exit
BigIron# reload
NOTE: Foundry Networks recommends that you reload the software immediately after saving a trunk group
configuration to flash memory, before making further configuration changes.
Syntax: trunk [server | switch] ethernet <primary-portnum> to <portnum> ethernet <primary-portnum> to
<portnum>
The server | switch parameter specifies whether the trunk ports will be connected to a server or to another Layer
2 or Layer 3 Switch. This parameter affects the type of load balancing performed by the Foundry device. See
"Trunk Group Load Sharing" on page 10-47. The default is switch.
Each ethernet parameter introduces a port group.
The <primary-portnum> to <portnum> parameters specify a port group. Notice that each port group must begin
with a primary port. After you enter this command, the primary port of the first port group specified (which must be
the group with the lower port numbers) becomes the primary port for the entire trunk group. For Gigabit Ethernet
modules, the primary ports are 1, 3, 5, and 7.
To configure a trunk group consisting of two groups of two ports each, enter commands such as the following:
BigIron(config)# trunk ethernet 1/1 to 1/2 ethernet 3/3 to 3/4
BigIron(config)# write memory
BigIron(config)# exit
BigIron# reload
Notice that the groups of ports meet the criteria for a multi-slot trunk group. Each group contains the same
number of ports (two) and begins on a primary port (1/1 and 3/3).
USING THE WEB MANAGEMENT INTERFACE
1. Log on to the device using a valid user name and password for read-write access. The System configuration
panel is displayed.
2. Click on the plus sign next to Configure in the tree view to display the configuration options.
3. Select the Trunk link.
• If the device does not have any trunk groups configured, the Trunk configuration panel is displayed, as
shown in the following example.
