ı want to ask that; On the switch ı know switch's mac address table.For exaple gi0/11 mac adddres:xxxx.xxxx (show mac-address table).And than ı want to learn this mac adress's IP ?is there command for this?
Get the mac-adress of devices from here then go to layer 3 device # show ip arp | inc mac-address. Sometimes you might need to ping that ip from layer 3 switch to get the arp.
Do a sh arp | inc the mac address and it will tell you what ip is associated with that mac. If the neighbor is another Cisco device and you have cdp enabled do a sh cdp neighbors.
Unfourtanately 1.step:Login the Switch and than show inter gi0/1 status and than ı have seen the mac adress.Then I wrote show arp | inc mac adress. But I Haven't seen where is my wrong?
Show IP arp will get you arp on Layer 3 device could be layer3 switch /router /firewall. So make sure where is your gateway interface vlan / interface with IP address.
I see,ı understood that but mine question is different ı wanted to learn that..After #show mac-address table command.There are mac-adresses.After I saw this command:Can ı write a command,from the table any mac adress's to learn it's ip?
Get the mac-adress of devices from here then go to layer 3 device # show ip arp | inc mac-address. Sometimes you might need to ping that ip from layer 3 switch to get the arp.
