Hi All,

Please help me. I have to decommissions some nodes and pools out of 1000 VIPs. Is there any way I can find it via CLI (GUI I know how to check but do not have access of GUI in the current environment)

 

  1. Find nodes which are associated with all Pools
  2. Pools which are associated with all VIPs

Thanks

Well in CLI its pretty easy with one-line command, to lookup an VIP or to look up a pool, one-line is a favorite. Try it.

 

To find a node if its part of any pool. where 1.1.1.1 is the node that you want to check if its part of any pool.

tmsh list ltm pool one-line | grep 1.1.1.1 | awk '{print $3}'

The output will be just the pool names.

 

Similarly to find the pools referenced in any VS. where my-app-pool-name is the pool name

tmsh list ltm virtual one-line | grep my-app-pool-name | awk '{print $3}'

The output will be just the VS names.

 

Same you can use to find the VS setup with a VIP, where 1.2.3.4:443 is my VIP

tmsh list ltm virtual one-line | grep 1.2.3.4:443 | awk '{print $3}'

If you want to do it on bulk, you can simply put a bash script and put a loop to find both the pool names and the corresponding VS details.

Hi jaikumar_f5, I have one more issue that is when ever I am running any .sh(bash script) it is show error. Few of them I have copied from this forum but not able to tset. Could you please help me on this. I am very new in F5 so may be not able to understand the way it work. For example in below script :-

 

! /bin/bash 

output=$(tmsh list ltm virtual |grep "ltm virtual" | awk -F" " '{ print $3 }') 

for LINE in ${output}; do

 pool=$(tmsh list ltm virtual ${LINE} pool |grep pool |awk -F" " '{ print $2 }')

 if [ $pool != none ]

 then

   echo "Virtual: ${LINE}:"

   tmsh list ltm pool $pool load-balancing-mode

 fi

 done
