Editing Virtual server IPs via script

The TMSH command to modify a virtual server's IP address is:

modify ltm virtual vs-name destination 1.2.3.4:80

This might help you generate the commands (run in bash):

tmsh list ltm virtual destination | tr '\n' ' ' \
| sed 's/ \+/ /g;s/ltm virtual/\ntmsh modify ltm virtual/g;s/nation 1\.1\.1/nation 2.2.2/g';echo

where 1.1.1 are the old octets being replaced with 2.2.2

Thank you so much Shaggy this will help out greatly!

I'm having trouble with this one. Maybe it's because I'm running version 11.5.1. Here's what I did:

1. Created a file named bash.sh in the /shared folder.
2. Ran the following command: chmod 755 /shared/bash.sh
3. Ran the following command: bash /shared/bash.sh

The output looked correct, the desired octet was changed:

modify ltm virtual vs-name { destination 10.10.207.x:80 }

But, the actual VS destinations were not changed. Below is the contents of the bash.sh file:

!/bin/bash

tmsh list ltm virtual destination | tr '\n' ' ' \
| sed 's/ \+/ /g;s/ltm virtual/\nmodify ltm virtual/g;s/nation 10\.10\.206/nation 10.10.207/g';echo

That is slick. Thank you!

If you are sure about the result, you can do it "on the fly". Please don´t forget saving to startup config:

tmsh list ltm virtual destination | tr '\n' ' ' | sed 's/ \+/ /g;s/ltm virtual/\ntmsh modify ltm virtual/g;s/nation 10\.131\.131/nation 10.132.132/g' | bash +x

tmsh save sys config
