I have 3 Cisco 2950 Switches. Recently my peripheral devices i.e., wireless access points and switches in laboratory environments on the LAN lost connectivity. If I unplug these devices from the Cisco switches into plain jane 3COM switch set at factory defaults these devices can connect to the network. I know nothing about configuring switches outside of some basic terminology. I need to resolve this issue as these 3 switches along with the router are the backbone of my LAN.
I have attached the config from the switches I got from telnet sessions.
