Remove commands

[FrankFlintstone16044]

Hi

I am working through CCNA material which focusses on configuring and validation.  This is great but I am looking to also remove the commands from the switch.

As an example (CCNA Etherchannel) 

Configure with channel-group 1 mode on

Validate with sh spanning-tree or sh etherchannel 1 summary

This all works but how do you remove the etherchannel?

When I try the "no" command, i.e: no channel-group 1 mode on 

I get this error % Invalid input detected at '^' marker.

I have the same issue as well when configuring access. I can configure all the access needs, passwords from line con 0 and vty and I can undo them with no command.  But with local username and password (username wendell secret odom) when I try to use the "no" command it keeps the logins but then won't me let log in?

I don't want to have to reset the switch every time I do this as its not practical for client sites

Any guidance appreciated community

No, solved it.  The channel group must be shutdown before any commands are entered.  Then change the int and then no shutdown brings the channel up with all interfaces having the right settings.  It does not work unless you shut down first!

may be, 
but as I know if the port-channel not take command (after add it) we force shut no shut to make it accept it.
anyway
glad your issue solved 
good job friend
