Well I mistakingly changed the IP address on a 3550 to an address outside of the subnet the switch belongs to. I can see the switch via CDP, but can't telnet to it because there are no routing entries to it. Is there some way (via CDP) that I can correct the IP address on this switch or am I forced to have someone local to the switch console in to fix it? BTW, I can't add a route entry to reach it. Thanks
Hi There, the other option I would do is that if you have a router on site that you can reach, would be to put a secondary ip address on it in the same subnet as your switch, and then telnet to the switch from this router, that should get you by !!
through CDP you should be able to get the IP configured in the switch (in case you don´t remember). Then use a router and place a secondary IP on the interface in the management VLAN of the switch. You should then be able to do a local telnet specifying the source IP from the router to the switch. Once you´re in, repeat the IP address configuration in the switch with the proper setting. Don´t forget to remove the secondary IP of the router interface.
