Configuring a LAG
5
NOTE
Configuring the LACP trunk threshold on a third-party device may occasionally cause performance
or incorrect traffic flow issues. To avoid this issue, configure the trunk threshold on either the
Brocade MLX series device only or on both the Brocade MLX series device and the third-party device.
Configuring an LACP port priority
In a dynamic or keep-alive LAG, a port priority can be configured at the global level.
Brocade(config)# lag blue dynamic
Brocade(config-lag-blue)# lacp-port-priority 100000
Syntax: [no] lacp-port-priority slot/port number
NOTE
This configuration is only applicable for configuration of a dynamic or keep-alive LAGs.
Configuring an LACP system priority
In a dynamic or keep-alive LAG, a system priority can be configured at global level.
Brocade(config)# lacp system-priority 4
Syntax: [no] lacp system-priority number
The number value specifies the value of the LACP system priority. This can be a value from 1 to
65535. The default system-priority value is 1.
NOTE
This configuration is only applicable for configuration of a dynamic or keep-alive LAGs.
Configuring an LACP timeout
In a dynamic or keep-alive LAG, a port's timeout can be configured as short (3 seconds) or long (90
seconds). After you configure a port timeout, the port remains in that timeout mode whether it is up
or down and whether or not it is part of a LAG.
All the ports in a LAG should have the same timeout mode. This requirement is checked when the
LAG is enabled on the ports. For example, to configure a port for a short LACP timeout, use the
following command.
Brocade(config)# lag blue dynamic
Brocade(config-lag-blue)# lacp-timeout short
Syntax: [no] lacp-timeout [long | short]
To delete the configuration, use the no form of this command.
The long keyword configures the port for the long timeout mode–90 seconds. With the long
timeout, an LACPDU is sent every 30 seconds. If no response comes from its partner after 3
LACPDUs are sent, a timeout event occurs, and the LACP state machine transition to the
appropriate state based on its current state.
