UCCX HA Keepalives

I have a client that wants to apply some QoS to UCCX keepalive messages between servers in an HA pair.  I've been trying to figure out what protocol or port they should prioritize, but am having difficulty identifying anything in documentation.

 

Any help would be appreciated.

Re: UCCX HA Keepalives

Its usually TCP port 5900.

 

I would suggest going through the "port utilization guide" of your CCX version.

 

For 10.6 :

https://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cust_contact/contact_center/crs/express_10_6/maintain_and_operate/guide/UCCX_BK_UAC60444_00_uccx-operations-guide-106/UCCX_BK_UAC60444_00_uccx-operations-guide-106_appendix_0101.html

 

Also as per 10.6 logs (I have removed the IP):

Feb 12 00:01:21.599 SGT %MCVD-LIB_TPL-7-UNK:source=com.hazelcast.cluster.ClusterService, message=[x.x.x.x]:5900 [UccxCvdCluster-1289912074000] Added Address[x.x.x.x]:5900 to list of dead addresses because of timeout since last read
