I was able to telnet into another Cisco 3750 switch from a Cisco SG300 switch. Then next day I cannot. I receive the message: "No Resources to Open New Connection."
I thought maybe the switch is being overworked and I did a show cpu utilization which showed on 15% cpu usage for all three metrics.
Maybe my previous telnet sessions are still open for some reason? How would I know?

Answered my own question.
At the priveleged-exec prompt I entered resume X where X = the session number. The session number can be found from the show sessions command.
