Uplink Failure Detection (Ufd) - Dell MXL 10GbE Reference Manual

Uplink Failure Detection (UFD)

Uplink failure detection (UFD) provides detection of the loss of upstream connectivity and, if you use this
with network interface controller (NIC) teaming, automatic recovery from a failed link.
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.

Uplink Failure Detection (UFD)
Specify one or more downstream interfaces. For interface,
enter one of the following interface types:
• Fast Ethernet: fastethernet {slot/port | slot/
port-range}
• 10 Gigabit Ethernet: tengigabitethernet {slot/
port |slot/ port-range}
• 40 Gigabit Ethernet: fortygigabitethernet {slot/
port |slot/ port-range}
• Port channel: port-channel {1-512 | 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.
Re-enables all UFD-disabled downstream interfaces in the
group. The valid group-id values are from 1 to 16.
Introduced on the MXL 10/40GbE Switch IO Module.
downstream — assigns a port or port-channel to the uplink-state group as a
downstream interface.
