How to find a switch's IP address?

Postby rolandbaker Sat Aug 12, 2017 9:05 am

How do I find out a switch's IP address? My co-worker hooked up a brand new laptop to a switch that was a stand alone switch and not hooked to the LAN. He did a DOS command and found the switch's IP address, and then used that info to make the laptop the next corresponding ip address number. he then used the laptop to ping the switch. but how did he do this? what dos command did he use?

I didn't find the right solution from the internet.

Perform a show mac address-table interface <switchport> on the switch that has the device(s) connected to it. Then go to the router for the VLAN specified in the previous command and perform a show ip arp vlan <vlan#> include <mac-address> . That will give you the IP address for the device.
