Enabling The Error-Disabled Recovery - Cisco Nexus 3548 Configuration Manual

Configuring Layer 2 Interfaces
Example
This example shows how to enable the err-disabled detection in all cases:
switch# configure terminal
switch(config)# errdisable detect cause all
switch(config)# shutdown
switch(config)# no shutdown
switch(config)# show interface status err-disabled
switch(config)# copy running-config startup-config

Enabling the Error-Disabled Recovery

You can specify the application to bring the interface out of the error-disabled (err-disabled) state and retry
coming up. It retries after 300 seconds, unless you configure the recovery timer (see the errdisable recovery
interval command).
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# errdisable recovery cause {all | udld | bpduguard | link-flap | failed-port-state |
pause-rate-limit | loopback}
3. switch(config)# show interface status err-disabled
4. (Optional) switch(config)# copy running-config startup-config
DETAILED STEPS
Command or Action
Step 1 switch# configure terminal
Step 2
switch(config)# errdisable recovery cause {all | udld |
bpduguard | link-flap | failed-port-state | pause-rate-limit
| loopback}
Step 3
switch(config)# show interface status err-disabled
Step 4 (Optional) switch(config)# copy running-config
startup-config
Example
This example shows how to enable err-disabled recovery under all conditions:
switch# configure terminal
switch(config)# errdisable recovery cause loopback
switch(config)# show interface status err-disabled
switch(config)# copy running-config startup-config
Purpose
Enters global configuration mode.
Specifies a condition under which the interface
automatically recovers from the err-disabled state, and the
device retries bringing the interface up. The device waits
300 seconds to retry. The default is disabled.
Displays information about err-disabled interfaces.
Saves the change persistently through reboots and restarts
by copying the running configuration to the startup
configuration.
