Hi - I've just noticed a strange problem that's occurring on our network. However, I believe that it's a fairly new problem.
Some of our switches are not allowing concurrent telnet connections to their vty lines. This is in spite of having multiple lines configured and available.
The problem only occurs with telnet; multiple ssh sessions are successful. 'show users' shows that I'm the only person connected and that I'm using the first vty line.
Any ideas would be appreciated. Unfortunately, googling 'telnet' and 'problem' yielded too many results ;-)
