Missing SET parameters on 3750 switch via Telnet?

Hello. When I telnet into my 3750, and then I ENABLE to get priviledge commands, I want to SET the SPANNING-TREE parameter.

I type SET ? and only get one option

MEMORY set memory paramters

When I type SHOW ?, I do see the parameter to show the SPANNING-TREE information.

Is there something else I need to enable?

Thanks, for your help...Jake

Ok, I've got some more information...

To set this parameter I can use the NO command such as

no spanning-tree bpduguard enable

but when I type ? two choices are given for the command NO. How do I use the second one?

When I type NO ?, I have the options of




So any ideas?

thanks, Jake

Re: Missing SET parameters on 3750 switch via Telnet?

ok, I figured out my problem...I feel like such a newb...

I had to get into the CONFIG mode then many more options were possible.

I figured out how to set the spanning-tree, then immediately got PORT-SECURITY errors about 1 every second. I didn't easily see how to disable that feature from Telnet, but was able to from the Cisco Network Assistant and/or the Java based web interface.

Once I turned off/disabled Port security for that port a SHOW RUNNING-CONFIG did not even display anything for that port. Guess that's to be expected, I would have preferred to see disabled, but finally, FINALLY, I can communicate with the network and internet.

All this just for testing purposes and a slow migration to the new switches.
