Conguring Uplink Failure Detection (PMUX mode)
To congure UFD, use the following commands.
1. Create an uplink-state group and enable the tracking of upstream links on the switch/router.
CONFIGURATION mode
uplink-state-group group-id
• group-id: values are from 1 to 16.
To delete an uplink-state group, use the no uplink-state-group group-id command.
2. Assign a port or port-channel to the uplink-state group as an upstream or downstream interface.
UPLINK-STATE-GROUP mode
{upstream | downstream} interface
For interface, enter one of the following interface types:
• 10 Gigabit Ethernet: enter tengigabitethernet {slot/port |slot/port-range}
• 40 Gigabit Ethernet: enter fortygigabitethernet {slot/port |slot/port-range}
• Port channel: enter 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:
upstream gigabitethernet 1/1-2,5,9,11-12
downstream port-channel 1-3,5
• A comma is required to separate each port and port-range entry.
To delete an interface from the group, use the no {upstream | downstream} interface command.
3. (Optional) Congure the number of downstream links in the uplink-state group that will be disabled (Oper Down state) if one
upstream link in the group goes down.
UPLINK-STATE-GROUP mode
downstream disable links {number | all}
• number: species the number of downstream links to be brought down. The range is from 1 to 1024.
