Dell PowerEdge FN I/O Module Configuration Guide 9.10(0.0)

To configure 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:
   • TenGigabit Ethernet: enter tengigabitethernet { slot/port | slot/port-range}
   • Port channel: enter 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:

   upstream tengigabitethernet 0/1-2,5,9,11-12
                                       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. 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}
   • Port channel: enter 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:

   upstream gigabitethernet 0/1-2,5,9,11-12
                                       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.
4. (Optional) Configure 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 : specifies the number of downstream links to be brought down. The range is from 1 to 1024.
   • all: brings down all downstream links in the group.
   The default is no downstream links are disabled when an upstream link goes down. To revert to the default setting, use the no downstream disable links command.
5. (Optional) Enable auto-recovery so that UFD-disabled downstream ports in the uplink-state group come up when a disabled upstream port in the group comes back up. UPLINK-STATE-GROUP mode downstream auto-recover The default is auto-recovery of UFD-disabled downstream ports is enabled. To disable auto-recovery, use the no downstream auto-recover command.
6. Specify the time (in seconds) to wait for the upstream port channel (LAG 128) to come back up before server ports are brought down. UPLINK-STATE-GROUP mode defer-timer seconds
   • NOTE: This command is available in Standalone and VLT modes only.
   The range is from 1 to 120.
7. (Optional) Enter a text description of the uplink-state group. UPLINK-STATE-GROUP mode description text The maximum length is 80 alphanumeric characters.
8. (Optional) Disable upstream-link tracking without deleting the uplink-state group. UPLINK-STATE-GROUP mode no enable The default is upstream-link tracking is automatically enabled in an uplink-state group. To re-enable upstream-link tracking, use the enable command.
