Secure switch to switch connection

Hi,

Does any one knows a way to secure switch to switch connection.

Doesn't matter if it is a trunk or access port, The only thing that is important is that if the other side is not a switch than the port needs to be shutdown or block the traffic.

Thanks in advance.

May be :

1. You can use the port security ..and stick the mac address of the switch on another switch.

(config-if)# switchport port-security

(config-if)# switchport port-security maximum 1 [1 is default]

(config-if)# switchport port-security violation shutdown [shutdown is default]

(config-if)# switchport port-security mac-address

But if there are many stations on one switch that want to pass the port they will be blocked because only one mac is allowed.

yes.....it will allow only 1 mac address ........

Really good question:)

Then its very hard to find other solution ...because I never heard about this kind of security between two switches...except normal password...ssh or telnet.

Regards

Please rate if it helps.
