Configuring the Minimum Number of Links to be Up for
Uplink LAGs to be Active
You can activate the LAG bundle for uplink interfaces or ports (the uplink port-channel is LAG 128) on the
I/O Aggregator only when a minimum number of member interfaces of the LAG bundle is up. For
example, based on your network deployment, you may want the uplink LAG bundle to be activated only if
a certain number of member interface links is also in the up state. If you enable this setting, the uplink
LAG bundle is brought up only when the specified minimum number of links are up and the LAG bundle
is moved to the down state when the number of active links in the LAG becomes less than the specified
number of interfaces. By default, the uplink LAG 128 interface is activated when at least one member
interface is up.
To configure the minimum number of member links that must be up for a LAG bundle to be fully up,
perform the following steps:
Specify the minimum number of member interfaces of the uplink LAG 128 bundle that must be up for
the LAG bundle to be brought up. The default minimum number of member links that must be active
for the uplink LAG to be active is 1. Enter the minimum-links number command in the Port
Channel Interface 128 Configuration mode to specify this value.
Dell(conf)#interface port-channel 128
Dell(conf-if-po-128)#minimum-links 4
Use the show interfaces port-channel command to view information regarding the configured
LAG or port channel settings. The Minimum number of links to bring Port-channel up is field in the
output of this command displays the configured number of active links for the LAG to be enabled.
