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 {1-512 | 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 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.
