Hi


I am trying to map  a port to Mac-add but i dont get any ports for a specific Mac-add


Here are the steps i do


Step 1. ping the server 192.168.25.1 --------- Successfull

Step 2. sh ip arp 192.168.25.1  -------------> this gives me the Mac-add of the server

Step 3. sh mac-address-table address 0014.sd12.ec02    ------------------> I dont see any ports when i run this command


Can anybody explain why this is happening when i can ping the server form the switch



Thanks

Hi,


Are you sure that is the correct mac address?


the mac can only contain A to F and 0 to 9 - not "s"

Hi Brennan,


The Mac-add i entered is just an example

I copy the Mac-add from Show ip arp 192.168.25.1 command and enter it into step 3 but no ports


Thanks

Ok.


Is it a Microsoft NLB address? or anything similar?


Can you source a ping from 192.168.25.1 to one of your switches SVI's, and then search for it's mac address?

What kind of device has the ip address? Is it a MS NLB cluster?
