This is a total noob question so I apologize. I have some C3750 switches that I am trying to config so that only SSH can be be used to log on. I successfully did this on one of the switches, and can no longer use telnet, but can use SSH to log on t...
Good day to all. We have a small LAN with less than 10 switches total. Including all the network printers and PCs and servers there are about 70 nodes in this building. In the data room, there are (6) 24-port Catalyst switches. I am trying to det...
I have 2 Catalyst 3560 24-port switches (call them switch-a and switch-b). They are linked together with a patch cable and not stacked (the c3750 is stackable but not the c3560). Is it possible to have a port-channel group with 2 ports, where one po...
I am new to VLANs and trunks. I had a conversation with an "expert" who told me that "no one uses VTP" and that if a switch gets replaced, that "it could take the whole network down". That seems absurd to me. Seems like if I had to replace a switch -...

I am going to try that "/allow-feature-upgrade" command-line switch (no pun intended). Thanks for posting! But what drives me nuts is, Cisco's web site (which is a great site by the way), when I select the exact model number of the switch, and I do...
I tried that too, and it worked, but after reloading the switch, when I ran "show version", now it says, License Type: Default. No valid license found. Will it run like that and work? I mean, I am telnetted into it right now, so it must be working....
gmcvb: How did you resolve your dilemma? When you said, "I don't see an image for it", are you referring to how, when you go to cisco's website to download a newer flash, like 150(9)SE2, the only option is IPBASE? There is the Universal - they put i...
