Configuring a trunk group
TurboIron(config)#no trunk ethernet 1 to 2 ethernet 3 to 4
Syntax: no trunk ethernet | pos <portnum> to <portnum>
Specifying the minimum number of ports in a static trunk group
You can configure devices to disable all of the ports in a trunk group when the number of active
member ports drops below a specified threshold value. For example, if a trunk group has 4 ports,
and the threshold for the trunk group is 3, then the trunk group is disabled if the number of
available ports in the trunk group drops below 3. If the trunk group is disabled, then traffic is
forwarded over a different link or trunk group.
For example, the following commands establish a trunk group consisting of 4 ports, then establish
a threshold for this trunk group of three ports.
TurboIron(config)#trunk e 28 to 34
TurboIron(config-trunk-38-34)#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>
•
<number> - Specify 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:
•
This feature is supported on static trunk groups only. It is not supported on LACP trunk groups.
•
When UDLD is enabled on a trunk port, 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”
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
