Configuring a trunk group
Syntax: [no] trunk hash-options include-layer2
Configuring a trunk group
1. Disconnect the cables from those ports on both systems that will be connected by the trunk
group. Do not configure the trunk groups with the cables connected.
NOTE
If you connect the cables before configuring the trunk groups and rebooting, the traffic on the
ports can create a spanning tree loop.
2. Configure the trunk group on one of the two Layer 2 switches or Layer 3 switches involved in
the configuration.
NOTE
Downtime is incurred when adding a new port to a trunk group. It is suggested that you
schedule the addition of ports to a trunk group to minimize downtime and its impact to the
production network.
3. Save the configuration changes to the startup-config file.
4. Dynamically place the new trunk configuration into effect by entering the trunk deploy
command at the global CONFIG level of the CLI.
5. If the device at the other end of the trunk group is another Layer 2 switch or Layer 3 switch,
repeat steps 2 through 4 for the other device.
6. When the trunk groups on both devices are operational, reconnect the cables to those ports
that are now configured as trunk groups, starting with the first port (lead port) of each trunk
group.
7. To verify the link is operational, use the show trunk command.
CLI syntax for configuring consecutive ports
in a trunk group
This section describes the CLI syntax for configuring consecutive ports in a trunk group. To
configure non-consecutive ports, refer to “CLI syntax for configuring non-consecutive ports in a
trunk group” on page 708. Configuration examples are shown in later sections of this chapter.
To configure a trunk group consisting of two groups of two ports each, enter commands such as the
following.
Brocade(config)#trunk ethernet 1/1 to 1/2 ethernet 3/3 to 3/4
Trunk will be created in next trunk deploy
Brocade(config)#write memory
Brocade(config)#trunk deploy
Syntax: [no] trunk ethernet <primary-port> to <port> [ethernet <primary-port> to <port>]
Syntax: trunk deploy
Each ethernet parameter introduces a port group.
