I have an issue with one of my remote switches where i am unable to telnet. My onsite engineer informs me there are no active vty sessions, I don't even get a username prompt before the window closes. I have removed the ACL on the vty line so see no reason why i shouldn't be able to telnet in.
1. I can ping the device with both ip and dns
2. Apart from 2 devices on the same subnet I can telnet to all the other devices in the domain and on the same subnet.
4. The access device is directly connected to a layer 3 switch (it's gateway)
4. I'm ruling out a firewall issue as connections are allowed to other devices on that subnet there shouldn't be a problem.
The sh ver uptime on one of the devices is over 4 years I think the box needs a reboot.
My sh line also shows no vty connections, likewise my sh sessions, seems quite weird.
Thanks in advance
