Good day Experts, i am trying to get the mac address that is connected to the interfaces of a Catalyst 4500 L3 Switch.
Connected to this switch (actualy we have 2) are only servers, because nobody ever noted witch server is connected to what interface, i want to do this now.
normaly when i give the command sh mac address-table interface fa0/1, the output should be like: (this is in a 2960 switch)
Mac Address Table
-------------------------------------------
Vlan Mac Address Type Ports
---- ----------- -------- -----
36 0008.54aa.56d9 DYNAMIC Fa0/1
Total Mac Addresses for this criterion: 1
but when i use the same command in the "Server switch" (4500) the output is this:
L3_Server_1#sh mac address-table interface gi5/2
Multicast Entries
vlan mac address type ports

and with this i can not to so much. i just need the mac address of the NIC that is connected to the server switch.
Does someone have some ideas ??
the interfaces are set like this:
L3_Server_1#sh run int gi5/2
Building configuration...
Current configuration : 114 bytes
!
interface GigabitEthernet5/2
switchport access vlan 22
switchport mode access
switchport voice vlan 244
end
Thanks a lot!

Hello Michael,
Try with this command:
Show mac-add int gi5/2

in the server switch 1 we have cat4500-entservicesk9-mz.150-2.SG.bin
the second server switch is actualy a Catalyst 4000 L3
in the server switch 2 we have cat4000-i5k91s-mz.122-25.EWA14.bin

Hello Michael,
this is the command for both IOS version, 12.2(25)EWA14 and 15.0(2)SG:
show mac-address-table interface
To display the MAC address table information for a specific interface, use the show mac-address-table interface command.
show mac-address-table interface type slot/port
Usage GuidelinesFor the MAC address table entries that are used by the routed ports, the routed port name is displayed in the ?vlan? column not the internal VLAN number.
Examples
This example shows how to display MAC address table information for a specific interface:
Switch# show mac-address-table interface fastethernet6/16
Unicast Entriesvlan mac address type protocols port
