i am a german guy, so please excuse my bad english.
I have a question about static MAC addresses on a WS-C3750G-48TS Switch.
I have no static adresses configured on my switch, but see some when execute the "show mac address-table static" command. And i mean not the 0000.0c07.ac01 addresse for HSRP, Spanning-tree or something else, which are forwarded to the CPU, i mean entries like this:
Switch#show MAC address-table interface g2/0/47 Mac Address Table -------------------------------------------
Vlan Mac Address Type Ports ---- ----------- -------- ----- 3 1212.1212.1212 STATIC Gi2/0/47 3 1414.1414.1414 STATIC Gi2/0/47 Total Mac Addresses for this criterion: 2
This entries not configured or dynamicly learned.
I suspected functions like gratitious-arp, but this is only for IP<->MAC translation. Then i have searched functions like gratitious-mac or mac-notification. I have searched for a function with tells the switchport: "Hey, that is my MAC address. There is no need to learn this address dynamicly", but with no luck.
Does anybody can tell me, why these MAC addresses are shown static, and not dynamicly?
Are there any port-security related configurations in interface Gi2/0/47? Could you post the running-configuration of this interface in concern, output of show mac-address-table interface Gi2/0/47 and also could you let me know what is connected to this interface?
