Information
You can assign physical port or port-channel interfaces to an uplink-state group.
You can assign an interface to only one uplink-state group. Each interface assigned to an uplink-state
group must be configured as either an upstream or downstream interface, but not both.
You can assign individual member ports of a port channel to the group. An uplink-state group can
contain either the member ports of a port channel or the port channel itself, but not both.
To delete an uplink-state group, enter the no downstream interface command.

Commands
downstream auto-recover
s S50 only
Enable auto-recovery so that UFD-disabled downstream ports in an uplink-state group automatically

Defaults
The auto-recovery of UFD-disabled downstream ports is enabled.
Command Modes
UPLINK-STATE-GROUP
interface Enter one of the following interface types:
Fast Ethernet: fastethernet {slot/port | slot/port-range}
1-Gigabit Ethernet: gigabitethernet {slot/port | slot/port-range}
10-Gigabit Ethernet: tengigabitethernet {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.
Version 8.4.2.3 Introduced on the S-Series S50.
upstream
Assign a port or port-channel to the uplink-state group as an upstream
interface.
