To disable the temperature polling, use disable stack-unit unit-number port port-number phy temp polling
command.
Setting the reset port to normal mode
When the temperature of the optical port reduces below the threshold, you can enable the reset port to normal. To enable the reset port
back to normal, use the following command.
• Assign the stack-unit and port numbers that have to be set from reset to normal mode.
EXEC mode
enable stack-unit unit-number port port-number transceiver
The system generates the below syslog message after successful conversion of port from reset mode to normal.
IFAGT-5-PORT_ENABLED: 10GBaseT transceiver port 1/2 in normal mode.
To verify if the optical port is set to normal mode, use the show interfaces interface-name command.

Automatic recovery of an Err-disabled interface
The Dell EMC Networking OS attempts to recover the interface from the Err-disabled state automatically based on the cause of the error.
You can configure the Dell EMC Networking OS to recover an interface from Err-disabled state automatically, if the interface is changed
to Err-disabled state due to the following:
• BPDU Guard
• FEFD
• MAC learning limit
• ARP inspection
Based on the automatic recovery configuration, when the interface is changed to Err-disabled state, the Dell EMC Networking OS invokes
a timer for the configured time-out interval. Upon expiration of the timer, the interface is moved to operationally up state if the
encountered error is fixed. If not, the interface is again moved to Err-disabled state again.
Dell EMC Networking OS generates syslog message for Err-disabled recovery when:
• The timer is started for recovery of an interface
• The recovery action is complete
Following is the sample syslog displayed when the timer for Err-disable recovery is started:
May 8 17:18:57 %STKUNIT1-M:CP %IFMGR-5-ERR_DIS_RECOVERY_TIMER_START: 180 seconds timer
started to attempt recovery of interface Gi 2/18 from error disabled state caused by bpdu-
guard.
Following is the sample syslog displayed when the recovery action is complete:
May 8 17:21:57 %STKUNIT1-M:CP %IFMGR-5-ERR_DIS_RECOVERY_COMPLETE: Error Disable Recovery
timer expired for interface Gi 2/18.
