2 {upstream | downstream} interface
Command Mode:
UPLINK-STATE-GROUP
Assigns a port or port-channel to the uplink-state group as an
upstream or downstream interface.
For interface, enter one of the following interface types:
10-Gigabit Ethernet: tengigabitethernet {slot/port |slot/
port-range}
40-Gigabit Ethernet: fortyGigE {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:
upstream tengigabitethernet 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, enter the no
{upstream |
downstream} interface command.
3
downstream disable links
{
number | all}
Command Mode:
UPLINK-STATE-GROUP
Configures 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.
number specifies the number of downstream links to be brought
down. Range: 1 to 1024.
all brings down all downstream links in the group.
Default: No downstream links are disabled when an upstream link
goes down.
Note: Downstream interfaces in an uplink-state group are put into a
link-down state with an UFD-Disabled error message only when all
upstream interfaces in the group go down.
To revert to the default setting, enter the no
downstream
disable links
command.
4
downstream auto-recover
Command Mode:
UPLINK-STATE-GROUP
(Optional) Enables 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.
Default: Auto-recovery of UFD-disabled downstream ports is
enabled.
To disable auto-recovery, enter the
no downstream
auto-recover
command.
5
description text
Command Mode:
UPLINK-STATE-GROUP
(Optional) Enters a text description of the uplink-state group.
Maximum length: 80 alphanumeric characters.
6
no enable
Command Mode:
UPLINK-STATE-GROUP
(Optional) Disables upstream-link tracking without deleting the
uplink-state group.
Default: Upstream-link tracking is automatically enabled in an
uplink-state group.
To re-enable upstream-link tracking, enter the enable command.
