Is there a way to quickly remove config from a range of ports?

Hello,

I am on a 48 port switch and I have shutdown ports 20-40 using the interface range command, now I need remove the lines of config from those ports.  Normally I use the no command but it takes ages as the ports are quite specific, is there a quicker way as I have to do this at another 28 sites!

Thanks

Hello Andy,

there is the default command that should restore the default configuration of a port

It should be something like

config t

default interface type x/y

You need to shut the interfaces again as default settings is not shut

Hope to help

Re: Is there a way to quickly remove config from a range of port

That is one switch done, can you see why this range wont work?

int range FastEthernet 0/1 -4 , fa 0/6 , fa 0/9 , fa 0/13 , fa 0/16-28 , fa 0/33-48 , gig 0/2

                                                                                              ^

It shows there is an issue between fa 0/16-28 , fa 0/33-48

                                                                  ^

Thanks

There's a limit of 5 parameters per range command.

You need to shut the interfaces again as default settings is not shut

BTW, I believe I've noticed not all devices shut status is impacted by the default interface command.  To be safe, I follow up default command with similar inteface range command to set or unset shut status as required.

Also, on some devices, defaulting an interface will impact other interfaces QoS settings.  (Just some QoS commands; interfaces controlled by same ASIC.)

Is there a way to quickly remove config from a range of ports?

Hello Andy,

You could use the default interface range command - this will literally erase all the ports' configuration back to their default settings. Could this be helpful?

Best regards,

Re: Is there a way to quickly remove config from a range of port

Hi Andy,

create different macro's with 5 int in each and then default those macros once

Command

Purpose

Step 1

configure terminal

Enter global configuration mode.

Step 2

define interface-rangemacro_name interface-range

Define the interface-range macro, and save it in NVRAM.

The macro_name is a 32-character maximum character string.

A macro can contain up to five comma-separated interface ranges. You do not need to enter spaces before or after the comma.

Each interface-range must consist of the same port type.

Step 3

interface range macromacro_name

Select the interface range to be configured by using the values saved in the interface-range macro called macro_name.

You can now use the normal configuration commands to apply the configuration to all interfaces in the defined macro.

Step 4

end

Return to privileged EXEC mode.

Step 5

show running-config | include define

Show the defined interface-range macro configuration.

Step 6

copy running-config startup-config

(Optional) Save your entries in the configuration file.

thanks

Re:Is there a way to quickly remove config from a range of ports

When you use the "default int range" command note that some IOS releases on some devices are picky on syntax for the interface ranges. I always specify them in the format:

fa1/0/1 - 6, fa1/0/9 - 11

My 3550's were the ones that were very finicky on the format they accepted.
