default command

hi, I am trying to reset a fastethernet port to default settings But I keep getting the Invalid input detected at '^' market. Could anyone help ? Thanks.

Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#default interface fastethernet 0/5
^
% Invalid input detected at '^' marker.

Switch(config)#

go into the interface configuration

Why is the ^ under the S in Switch? That command should work.

Because of the way the editor on this site works; it truncates leading spaces.

You don't need to be in interface config for that command to work - Is that command supported in the code that you're running?

What version of code are you running?

rob42

The command works with IOS Version 12.1(6)EA2c, RELEASE SOFTWARE (fc1), running on a C2950 switch. It doesn't seem to be supported with CPT, mind. Are you running CPT or are you using 'real hardware'?

What output are you getting from...

(config)#default interface ?

My 2950 output is...

None of the default commands are accepted in Packet Tracer.

atippett

You will have to use the no command on every command you've made on the interface.

Ahhh... This is just one of the reasons for using some real equipment. I've seen many posts suggesting that real equipment is not necessary... I know it's an expense that not everyone can justify, but (here in the UK, anyway) one can get some very inexpensive kit. I got two C2950 Switches for just £35, the pair.

CPT is an excellent SIM, but there are some things that you can't do, and you've just discovered one of them.

rob42

You could just edit the startup-config file.

E.g:
If your config has this entry...
!
interface FastEthernet0/0
ip address 192.168.2.1 255.255.255.0
duplex auto
speed auto
!

... if you edit it to...

!
interface FastEthernet0/0
!

... that would effectively 'reset' that interface.

I haven't used CPT in awhile, but I believe you can't even use the show interfaces status command. Sigh.

You're correct. There's quite a few very useful analytical commands that just aren't supported.

thanks.
