Connectivity Guide

• If you do not assign upstream interfaces to an uplink-state group, the downstream interfaces are not disabled.
Conguration:
1 Create an uplink-state group in CONFIGURATION mode.
uplink-state-group group-id
2 Congure the upstream and downstream interfaces in UPLINK-STATE-GROUP mode.
upstream {interface-type | interface-range[ track-vlt-status ] | VLTi}
downstream {interface-type | interface-range}
3 (Optional) Disable uplink-state group tracking in UPLINK-STATE-GROUP mode.
no enable
4 (Optional) Provide a descriptive name for the uplink-state group in UPLINK-STATE-GROUP mode.
name string
5 Congure the number of downstream interfaces to disable, when an upstream interface goes down in UPLINK-STATE-GROUP mode.
downstream disable links{number | all}
6 (Optional) Enable auto-recovery of downstream interfaces that are disabled in UPLINK-STATE-GROUP mode.
downstream auto-recover
7 (Optional) Congure the timer to defer the UFD actions on downstream ports in UPLINK-STATE-GROUP mode. When you have
congured to track the VLT status in a VLT network, if VLT port-channel is an upstream member of uplink-state group, then the defer
timer triggers when the VLT status goes operationally down instead of the operational status of the peer port-channel.
defer-time timer
8 (Optional) Clear the UFD error disabled state of downstream interfaces in EXEC mode.
clear ufd-disable
