Running tmsh commands on multiple devices at once

Prerequisite: You will need a box that can ssh to all of your devices. "Pivot box" or "Jump box"

--Using CLI via F5 box or *Nix box

Shown below on a Version 9 box: Show me: hostname and kernel version and BIGIP version

&& - Will execute the command whether the previous command completed successfully.

while read HOST ; do echo "" | ssh $HOST "uname -a && date && echo -en '\n' && b version show | head -6 | sed 's/Final*//'" ; done < f5hosts.txt

f5hosts.txt --a list of all of the boxes you want to run tmsh commands, by hostname or IP

in between the quotes you list out the tmos commands. ie. "tmostcommand && tmostcommand && tmoscommand"

while read HOST ; do echo "" | ssh $HOST "tmostcommand && tmostcommand && tmoscommand" ; done < f5hosts.txt

Example:

while read HOST ; do echo "" | ssh $HOST "tmsh show ltm persistence persist-records && tmsh show ltm nat all && show sys hardware  " ; done < f5hosts.txt

If you prefer you can pipe everything out to a file.

while read HOST ; do echo "" | ssh $HOST "tmsh show ltm persistence persist-records && tmsh show ltm nat all && show sys hardware  " ; done < f5hosts.txt
