Usage Information
After you enter the command, to assign upstream and downstream interfaces to the group, enter Uplink-State-
Group Conguration mode.
An uplink-state group is considered operationally up if at least one upstream interface in the group is in the Link-Up
state.
An uplink-state group is considered operationally down if no upstream interfaces in the group are in the Link-Up
state. No uplink-state tracking is performed when a group is disabled or in an operationally down state.
To disable upstream-link tracking without deleting the uplink-state group, use the no enable command in uplink-
state-group conguration mode.
Example
DellEMC(conf)# uplink-state-group 16
DellEMC(conf)#
02:23:17: %RPM0-P:CP %IFMGR-5-ASTATE_UP: Changed uplink state group Admin
state to up: Group 16
DellEMC(conf)#
