What will happen with a switch if another node e.g. a printer gets the same IP address at VLAN1 on the switch?
That is what happened for me. Someone accidentally give a printer the same IP address as VLAN1 on one of two switches. Nobody noted it because the printer and the switch worked well, until one day I should Telnet the switch
Then I gave the printer another IP and cleared the DHCP address pool. But I still cant telnet or ping the switch. Otherwise the switch works fine.
Via the command show cdp neighbour detail on the neighbour switch, I can verify that it is the correct IP address I try to connect to, and of course Ive Telnetted the switch before.
Why cant I get in contact with the switch? Nothing has changed on the switch.
Is it really necessary to reboot it?
TIA

Hi Mahmood
Maybe I could, but I don't have physical acces to the switch, unless I drive 200 KM :-(
I hoped that I could do something remote ;-)
Thanks

On the router/layer3 switch at the site do a 'clear arp' and try getting to it?
Pls. rate the post if it helped.

Try getting into the GUI rather than Telnet. Use a browser and go to the VLAN 1 IP address.
I've had similar issues and this seems to work.

Go to the router it is attached to then source your telnet from the directly attached interface and see if you can get to it that way , this will rule out a default gateway problem .

Had a similar problem once. Got someone to power the switch off/on, all cured. Drastic but.....
