Save. 

Note: Do not worry about the status section indicating 

Failed

. This will change to 

Active

 once the 

zone’s IP address / FQDN has been saved. 

If there are more than 6 FEPs behind the main Hardware load balancer, add further neighbor zones 
(each with unique names) until all FEPs are referenced as a Peer x Address. 

Note: Do not configure any Search rules to point to these zones.  These zones are receive only. 

Test calls from endpoints registered on the video network to MOC clients registered on OCS. 

For example, call steve.hight@test-customer.com or mary.jones@test-customer.com from both SIP 
and H.323 endpoints registered on Cisco VCS Control.
