Hello i have a Cisco 3750G switch and i need to find the IP address and I dont have a serial cable, so I need the IP address to login into the web-interface. Does it need to be connected to a network? I have a big network 100+ users so IP scanning is not an option

Thanks

  • Do you even know if it has been configured with an IP address? – user36472 Jan 29 at 9:29

  • Check for LLDP or CDP advertisements on connected ports (proper tool or packet capturing) or adjacent devices - these usually include the (main) local IP address.
  • Check the DHCP server for a current lease on the switch's MAC address (should be printed on the back).
  • Run a quick ARP scan, the switch shows up with its MAC address.
