How to I list the VSs that has VLAN enabled on it?

Hello,

 

When a new VLAN is created on our LTMs in one of our environments, they should be enabled on a couple of Performance Layer 4 virtual servers. As part of the VS creation checks I'd like to be able to run a command to ensure that this has been done.

 

Is there a way of running a command where I can get a list of Virtual Servers that a VLAN is enabled on?

 

I can do "sh running-config ltm virtual vlans" and then check through but would like something that gets to the point a bit faster.

 

Thanks, Stewart.

    How about a shell script?

    Against better judgement I wrote a very simple one for you (sensitive people should close their eyes):

    /bin/bash

virtualcount=$(tmsh show running-config ltm virtual /Partition/*myname* vlans | grep virtual | wc -l)
vlancount=$(tmsh show running-config ltm virtual /Partition/*myname* vlans | grep "External" | wc -l)

if [ $virtualcount == $vlancount ]
    then
        echo "All have vlans"
else
    echo "Missing vlans"
fi

    A minor mod:

    !/bin/bash

if [ "$1" == "" ]
then
    echo "Usage: find-vlans.sh 
    echo ""
    echo "Example: find-vlans.sh vlan-1234
    echo ""
    echo ""
    exit
fi

echo "The following virtual servers are enabled for the $1 VLAN:"
tmsh list ltm virtual one-line |grep vlans |grep $1 |awk -F" " '{ print $3 }'
