Source notes citing this source

• Conference Factory template configuration is not replicated across Expressway cluster peers; Cisco documents this as expected behaviour. in context
• For the alarm requiring manual synchronization of configuration, Cisco directs running xcommand ForceConfigUpdate as admin on the subordinate, which deletes its configuration and forces an update from the primary; back up first. in context
• H.323 mode must be on for each Expressway cluster peer because clustering uses H.323 communication between peers; if it is off, an Invalid clustering configuration alarm is raised. in context
• A cluster replication error can be raised because the NTP server is unreachable; the fix is to configure an accessible NTP server on System > Time. in context
• If a replication error persists after ForceConfigUpdate, Cisco advises upgrading the primary again with the original upgrade package; the alarm typically clears 10 to 20 minutes after reboot. in context
• Cluster replication health is checked at System > Clustering on each peer, where the cluster database status should read Active. in context
• The documented cluster restart sequence is to restart the primary, wait until its web interface is reachable and replication is healthy, then restart the other peers one at a time. in context
