This is a short post.
I tried to make a change to a Trunk configuration,. I needed to set up the Trunk so that it would use TCP and to port 5060. I made the change in Topology Builder, and everything looked great. However, when I tried to publish the change, the Publish Topology option was greyed out. I could not publish the change.
No errors were generated and nothing told me that there was a conflict. However, the solution was an easy one. I turned off “Enable hardware load balancer monitoring port” which was also set to use 5060. I later changed the monitoring port.
The next step will be to let the load balancer team know that they need to update their monitoring port so the load balancer can know not to direct traffic to a downed server.
