61 Uplink Failure Detection (UFD) Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if you use this with NIC teaming, automatic recovery from a failed link. Topics: • clear ufd-disable • debug uplink-state-group • description • downstream • downstream auto-recover • downstream disable links • enable • show running-config uplink-state-group • show uplink-state-group • uplink-state-group • upstream clear ufd-disable Re-enable one or more downstream interfaces on the switch/router that are in a UFD-Disabled Error state so that an interface can send and receive traffic. Syntax Parameters clear ufd-disable {interface interface | uplink-state-group group-id} interface interface Specify one or more downstream interfaces. For interface, enter one of the following interface types: • 1 Gigabit Ethernet: gigabitethernet {slot/port | slot/port-range} • For a 10-Gigabit Ethernet interface, enter the keyword TenGigabitEthernet then the slot/port | slot/port-range • Port channel: port-channel {1-128 | port-channel-range} Where port-range and port-channel-range specify a range of ports separated by a dash (-) and/or individual ports/port channels in any order; for example: gigabitethernet 1/1-2,5,9,11-12 port-channel 1-3,5. A comma is required to separate each port and port-range entry. uplink-state-group Re-enables all UFD-disabled downstream interfaces in the group. The valid group-id group-id values are from 1 to 16. Defaults A downstream interface in a UFD-disabled uplink-state group is also disabled and is in a UFD-Disabled Error state.
