Dell PowerConnect B-RX Configuration Manual page 319

Syntax: trunk-threshold <number>
You can specify a threshold from 1 (the default) up to the number of ports in the trunk group.
When a LAG is shut down because the number of ports drops below the configured threshold, the
LAG is kept intact and it is re-enabled if enough ports become active to reach the threshold.
NOTE
Trunk threshold should be configured only at one end of the trunk. If it is set on both sides, link
failures will result in race-conditions and the trunk will not function properly.
Configuring LACP port priority
In a dynamic or keep alive LAG, the port priority determines the active and standby links. The other
ports (with lower priorities) become standby ports in the trunk group.
BigIron RX(config)# lag blue dynamic
BigIron RX(config-lag-blue)# lacp-port-priority 100000
Syntax: [no] lacp-port-priority <slot/port> <number>
For a port specified by the <slot/port> variable, you can specify a priority in the <number> variable
from 0 – 65535. A higher value indicates a lower priority. The default 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 or long. Once a port is
configured with a timeout option, it will remain in that timeout mode whether it's up or down, or
part of a trunk or not.
All the ports in a trunk should have the same timeout mode. This is checked when the LAG is
enabled on ports. To configure a port for a short LACP timeout use the following command.
BigIron RX(config)# lag blue dynamic
BigIron RX(config-lag-blue)# lacp-timeout short
Syntax: [no] lacp-timeout [long | short]
The long parameter configures the port for the long timeout mode.
The short parameter configures the port for the short timeout mode.
NOTE
This configuration is only applicable for configuration of a dynamic or keep-alive LAGs.
