Configure uplink failure detection

Consider the following before configuring an uplink-state group:

  • You can assign a physical port or a port channel to an uplink-state group.
  • You can assign an interface to only one uplink-state group at a time.
  • You can designate the uplink-state group as either an upstream or a downstream interface, but not both.
  • You cannot assign both a port channel and its members to an uplink-state group, which would make the group inactive. The port channels and individual ports that are not part of any port channel can coexist as members of an uplink-state group.
  • The downstream ports are disabled in an order starting from the lowest numbered port to the highest.
  • If you disable an uplink-state group, the downstream interfaces are not disabled, regardless of the state of the upstream interfaces.
  • If you do not assign upstream interfaces to an uplink-state group, the downstream interfaces are not disabled.

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. (Optional) Clear the UFD error disabled state of downstream interfaces in EXEC mode.
    clear ufd-disable
