When you create uplink-state group in a switch operating in VLT mode, ensure that all the nodes in the VLT setup have same
configuration for uplink state groups with VLT port-channel as member. This makes all the nodes independently operational and
to operate in sync.
When you configure VLT port-channel as upstream member in the uplink state group, the system tracks the fabric Status of
VLT. When the fabric status goes down, the uplink state group in each VLT node disables the downstream VLT port-channel
local to the node.
Configuration:
1. Create an uplink-state group in CONFIGURATION mode.
uplink-state-group group-id
2. Configure the upstream and downstream interfaces in UPLINK-STATE-GROUP mode.
upstream {interface-type | interface-range}
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. Configure 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) Configure timer to defer the UFD actions on downstream ports in UPLINK-STATE-GROUP mode.
defer-time timer
8. (Optional) Clear the UFD error disabled state of downstream interfaces in EXEC mode.
clear ufd-disable
