Troubleshooting Port Security

Cannot Set the Port Security Mode

Symptom

Cannot set the port security mode.

[AC-GigabitEthernet0/0/1] 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.

[AC-GigabitEthernet0/0/1] undo port-security port-mode

[AC-GigabitEthernet0/0/1] port-security port-mode autolearn
