You didn't tell us which version of IOS you have but if I recall correctly, when you do a "sh access-list 150" you will get it with a bunch of line numbers. Then it is just a matter of:

ip access-list extended 150

x permit ip any host 10.205.102.12

y permit ip host 10.205.102.12 any

Where x and y are numbers between the line numbers of those two lines.

My Cisco IOS version is 12.2(17a)..

I didn't get any line number as u given in the

sh access-list 150

The first thing to do is a "show access-list" of this access-list. Since this looks like an extended access-list, you will see seq# of the left side of them.

Lets say the you have:

100 permit ip any host 10.205.31.100

110 permit ip host 10.205.31.100 any

conf t

ip access-list extended 150

101 permit ip any host 10.205.102.12

102 permit ip host 10.205.102.12 any

exit

ip access-list resequence "Access-list name" 10 10

press enter then exit

This should put them in order by seq of 10.

Rate it if this helps...

I didn't get any sequence number in the left side

vinoth,

It's not easy to live with the old IOS. (grin)

What I can recommend is that you have to copy the whole part of ACL to the notepad or something like that. Then modifing the ACL to be the new one. After that just remove the existing ACL and replace the new one real quick.

vinoth,

I agree with HTH.

The first line in notepad should have the - no ip access-list 150 -

Then the rest of the access list with the modifications included.

Copy the whole list and in config mode

paste the it in. Now I would have a reload statement applied prior to this with a 5-10 minute time frame just in case if the equipment isn't local to you. If all goes well then cancel the reload.

Vinoth:

1.) Make sure you have permission to remove any ACLs during production times.

2.) If you do, remove the access list from the interface first. Im assuming its a security list that is being applied to a particular interface.

interface serial 0/0

no ip access-group 150 [in|out]

3.) Copy the entire ACL onto a Notepad document. Insert changes/adds. Then paste the revised ACL to the routers config.

4.) re-apply the access-list to the interface.

5.) Save config and back it up to the tftp server if you use one.

Victor,

That's what I'm thinking of.

5P!

lamav · ‎03-31-2009

Toshi. Thanks! LoL :-)

lamav · ‎03-31-2009

Vinoth:

Just to be super duper clear, after you remove the access list from the interface in step 2, you can then go into global config mode and delete the ACL itself, step 2a:

router (config)#no ip access-list 150
