NimbostratusHow to disable Virtual Server in LTM using TMSH command?
Hi, we need to accomplish following task using shell script/tmsh in LTM v 11.3 For maintenance purpose, we need a script which will bring down all VSs related to particular client & can bring it up on e maintenance window is over. Script should take client name as input & disble/enable all VS related to that client. Is it possible doing shell/perl script? Which commands I should use for tmsh, also will it support switch statement for looping or checking client name?

how does client name relate to virtual server (i.e. how do you know what virtual server is based on client name)?
Pranav_73262we will have to do manual mapping of client names with VS. e.g.: switch (Client A) { Disable VS1 Disable VS2 } switch (Client B) { Disable VS3 Disable VS4 } Is it possible to do?

Here's an idea. Put the client name in the description block of the virtual server definition and use a shell script like this:
!/bin/bash if [ -z "$1" ] || [ -z "$2" ] then echo "Usage: clientdown.sh [CLIENTNAME] [UP/DOWN]" elif [ "$2" != "UP" ] && [ "$2" != "DOWN" ] then echo "Usage: clientdown.sh [CLIENTNAME] [UP/DOWN]" else output=$(tmsh list /ltm virtual one-line |grep "description $1" | awk -F" " '{ print $3 }') if [ -z "${output}" ] then echo "No client found by that name" else for LINE in ${output} do if [ "$2" == "UP" ] then echo "Enabling virtual \"${LINE}\" for client $1" tmsh modify /ltm virtual ${LINE} enabled elif [ "$2" == "DOWN" ] then echo "Disabling virtual \"${LINE}\" for client $1" tmsh modify /ltm virtual ${LINE} disabled fi done fi fiI didn't bother making the command line arguments case-insensitive, so you'd need to have a naming/case convention for your client names (or modify the script). This will search through the VIP list for a given client name in the description field and then enable or disable those.
