Configuring a trunk group
For example, the following commands establish a trunk group consisting of four ports, and then
establish a threshold for this trunk group of three ports.
Brocade(config)#trunk e 3/31 to 3/34
Brocade(config-trunk-3/31-3/34)#threshold 3
In this example, if the number of active ports drops below three, then all the ports in the trunk
group are disabled.
Syntax: [no] threshold <number>
The <number> variable specifies a threshold number from 2 (default) up to the number of ports in
a trunk group. The total number of threshold ports must be greater than 1.
NOTE
When using the no threshold command, it is not necessary to enter a number.
Configuration notes for specifying ports in a static trunk group
• Specifying ports in a trunk group is supported on static trunk groups only. It is not supported on
LACP trunk groups.
• When unidirectional link detection (UDLD) is enabled on a trunk port, the trunk threshold is not
supported.
• The disable module command can be used to disable the ports on a module. However, on 10
Gbps modules, the disable module command does not cause the remote connection to be
dropped. If a trunk group consists of 10 Gbps ports, and you use the disable module command
to disable ports in the trunk group, which then causes the number of active ports in the trunk
group to drop below the threshold value, the trunk group is not disabled.
• If you establish a threshold for a trunk used in conjunction with Metro Ring Protocol (MRP) on
10 Gbps interfaces, then you must also enable Link Fault Signaling (LFS).
• If you specify a threshold for a trunk group, the other end of the trunk group must also have the
same threshold configuration.
Monitoring a trunk port
You can monitor the traffic on an individual port of a static trunk group. For configuration details,
refer to “Monitoring an individual trunk port” on page 930.
Configuring outbound rate shaping for a trunk port
You can configure the maximum rate at which outbound traffic is sent out on a static trunk port. For
configuration details, refer to “Configuring outbound rate shaping for a trunk port” on page 1953.
Enabling sFlow forwarding on a trunk port
You can enable sFlow forwarding on individual ports of a static trunk group. For configuration
details, refer to “Enabling sFlow forwarding on individual trunk ports” on page 546.
