WS-C2960-24TC-L - %PLATFORM_PM-3-HOSTACCESSFAIL - error

Hello,

I have issue with 3 ports on the switch.

Once I put he following commands under the port I got error message : 

authentication control-direction in
authentication host-mode multi-auth
authentication port-control auto
authentication periodic
authentication timer restart 240
authentication timer reauthenticate server
authentication timer inactivity server
mab

 

*Jun  7 06:45:18: %PLATFORM_PM-3-HOSTACCESSFAIL: Unable to configure hardware to restrict host access on Fa0/17.  Port may not behave as expected.
*Jun  7 06:45:18: %PM-4-ERR_DISABLE: port-mode-failure error detected on Fa0/17, putting Fa0/17 in err-disable state

 

I have the same configuration under other ports and I don't have any issue.

When I remove these commands , these 3 ports are working fine.

 

What's going on ?  Can you help me to find the root cause ? 

 

The device is WS-C2960-24TC-L, Version 12.2(58)SE2

 

The current configuration of port is here : 

interface FastEthernet0/17

 switchport access vlan 274
 switchport mode access
 switchport nonegotiate
 switchport voice vlan 1293
 speed 100
 duplex full
 mls qos trust dscp
 spanning-tree portfast

 

Thank you,

 

Jan

Hi,These kind of error

Hi,

These kind of error message you get whenever your TCAM gets full. It should not be popping up for 12.2(58)SE2. It was resolved in the earlier IOS versions itself. Need to do deep dive to find any un resolved caveats for this version of IOS.

Hi,

Hi,

Rather doing a manual shut/no shut you can enable auto recovery for error-disabled.

port-mode-failure     Enable timer to recover from port mode change failure

Hope this helps

Regards

Karthik
