Troubleshooting Port Security

Cannot Set the Port Security Mode

Symptom
Cannot set the port security mode.
[Switch-GigabitEthernet1/0/1] port-security port-mode autolearn
Error:When we change port-mode, we should first change it to noRestrictions, then change
it to the other.
Analysis
For a port working in a port security mode other than noRestrictions, you cannot change the port
security mode by using the port-security port-mode command directly.
Solution
Set the port security mode to noRestrictions first.
[Switch-GigabitEthernet1/0/1] undo port-security port-mode
[Switch-GigabitEthernet1/0/1] port-security port-mode autolearn
The maximal retransmitting times
EAD timeout: 30m
