Can iquery operate on multiple interfaces?

From what I have found out, only one IP address is allowed for each system, even though the service is available on multiple addresses.

From "man gtm_add":

"      gtm_add is an interactive script that is used to integrate a new BIG-IP GTM system into a sync group that is already defined on one or more remote BIG-IP GTM systems.

      The script wipes out the current configuration of the GTM system on which it is run and replaces it with configuration of the remote GTM systems in the specified sync

      group.

"

So there is only a "replace" but no "add" functionality in the facility.

Also if you look at the command /usr/local/bin/gtm_add itself, which is a perl script, Lines 113-176 (BIG-IP 13.1.1) show that only one address will be taken. if you are on a different version of BIG-IP, look for the starting line:

while (@ARGV > 0) {

in the script.
