The only way you can do that without remoting into the switch1 would be to have the same VLAN (layer2) connect from switch 1 to switch 4. You could then create a SVI (switched virtual interface - i.e. interface vlan <X>) on switch4 in the same vlan and ping the IP of the remote PC. Then do a show arp on switch 4 and you should see the mapping of mac to IP.
Now if you have access to switch 1 - just remote into the switch and issue "show mac address-table dynamic <interface>". Not sure on the command as they change from switch to switch but show mac? should get you going. Also this only works on access ports with 1 device connected. If you have more than one device connected you will get a number of mac address shown. If you have more then 1 device then you can do the same procedure as above but only create the SVI on the original switch.

I only need to find out and know the MAC address on PC 1 Hi Could anyone explain for me how do I exactly find out the MAC address of PC 1 connected to Switch 1 if I am sitting on Switch 4? Assume that we have full connectivity. I only need to find out and know the MAC address on PC 1 connected to SW1 Thanks Ahmed _______________________________________________ Free CCIE R&S, Collaboration, Data Center, Wireless & Security Videos :: iPexpert on YouTube: www.youtube.com/ipexpertinc _______________________________________________ Free CCIE R&S, Collaboration, Data Center, Wireless & Security Videos :: iPexpert on YouTube: www.youtube.com/ipexpertinc
