MAC address Binding

[manoj.electronics]

HI All,

I have Cisco 2960-24 TC-L switch,I want to do the MAC address binding and follwed following steps:

went to Port security enabled it for max. of 3 Mac address. and created 3 MAC address into it. But when i set max. to 4 or 5 it automatically takes the MAC address of fourth device connected on it. I want to put manually instead of automatically. also what to do if i need to remove the current authorized MAC address on that port.Please help

connectivity:

Cisco 2960----------Unmanaged switch--------User 1

                                        I____________User 2

                                        I____________User 3

                                        I____________User 4

Hi Manoj,

If you are not able to configure the port security properly then please remove the hub and then configure again the port.

Just follow this:

9XCI002(config)#int fa0/23

99XCI002(config-if)#switchport port-security

99XCI002(config-if)#switchport port-security  maximum 5

99XCI002(config-if)#switchport port-security mac-address F8:72:EA:23:CA:DC

99XCI002(config-if)#switchport port-security mac-address 6C:41:6A:92:AC:38

99XCI002(config-if)#switchport port-security mac-address F8:72:EA:23:CA:A5

99XCI002(config-if)#switchport port-security mac-address 6C:41:6A:92:AB:C5

99XCI002(config-if)#switchport port-security mac-address 60:73:5C:C3:89:93

99XCI002(config-if)#switchport port-security mac-address 60:73:5C:A7:3B:BB

Total secure mac-addresses on interface FastEthernet0/23 has reached maximum limit.

99XCI002(config-if)#switchport port-security  violation  shutdown

Hope it helps
