Architecture and Scalability for Cisco Deployments

For Cisco deployments, UC Monitor requires a management console and at least one collector. For small environments or initial rollouts with only one Cisco Unified Communications Manager cluster, a standalone system is sufficient. For larger deployments, a distributed system is recommended.

In general, one UC Monitor collector is required for every switch that handles call setup flows from the Unified Communications Manager call server.

The following diagram illustrates UC Monitor in a Cisco-only environment:

Cisco recommends that you deploy Cisco Unified Communications Manager so as to ensure failover capability and processing redundancy:

• Do not allow the members of a call server cluster to share a VLAN or switch.
• Use different access switches. Connect them to the same distribution or core switch, or to different distribution or core switches.
• Place call servers in different buildings within the same LAN or WAN.
