Deployment Guide
To delete an uplink-state group, enter the no downstream interface command.
Parameters
interface Enter one of the following interface types:
• 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:
tengigabitethernet 1/1-2,5,9,11-12 port-channel 1-3,5. A comma is
required to separate each port and port-range entry.
Defaults none

Command History
Version Description
9.9(0.0) Introduced on the FN IOM.
9.4(0.0) Supported on the FN I/O Aggregator.
Usage 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. Congure each interface assigned to an uplink-state
group 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.
Related Commands
• upstream — assigns a port or port-channel to the uplink-state group as an upstream interface.
• uplink-state-group — creates an uplink-state group and enables the tracking of upstream links.
downstream auto-recover
Enable auto-recovery so that UFD-disabled downstream ports in an uplink-state group automatically come up when a disabled upstream
port in the group comes back up.
Syntax
downstream auto-recover
To disable auto-recovery on downstream links, use the no downstream auto-recover command.
Defaults The auto-recovery of UFD-disabled downstream ports is enabled.
