For IP Communications deployments of more than 30,000 phones, multiple Operations
Manager servers can be used to monitor the deployment. These servers can share device
and credential information between them, and administrators can perform centralized
device and credential management. By integrating with a Cisco Secure Access Control
Server, administrators can centrally control user access. Each of these servers will roll up
the status of the network being monitored to a higher-level entity (typically a MOM)
through SNMP traps and syslog notifications.
