Monitoring the Virtualized Campus
Network virtualization for the campus is a cohesive, extensible architecture to logically partition the
network infrastructure. It simplifies network operations and reduces costs while increasing flexibility
and agility and enhancing productivity. In today’s evolved networking environments, typical
campus network designs use a mix of Layer 2 switching technologies at the network edge (access
layer) and Layer 3 routing technologies at the network core (distribution and core layers). Thus,
network virtualization can be achieved at the network access layer (Layer 2) by means of VLANs
and at the network core (Layer 3) by using Generic Routing Encapsulation (GRE) tunnels, Virtual
Route Forwarding (VRF)-Lite, and Multiprotocol Label Switching (MPLS)–based Layer 3 VPNs to
partition the routed domain and thus achieve scalable end-to-end virtualization.
Cisco NAM monitors traffic flowing through the virtualized campus. For designs using MPLS VPNs,
Cisco NAM can identify, monitor, and capture MPLS VPN traffic. Because Cisco NAM can present
detailed “before and after” traffic information, it can ease the deployment of a virtualized campus
design by facilitating the critical planning and management activities required to help ensure a
smooth transition.
Flexible Deployment Scenarios
Cisco NAM can be deployed in the Cisco Catalyst 6500 Series at LAN aggregation points (for
example, in the core and distribution layers) for proactive monitoring; at service points (for
example, in data centers, or Cisco Unified Communications Manager clusters in IP telephony
networks) where performance monitoring is critical; and at important access points (critical clients,
IP phone closets) where quick troubleshooting is required. It can also be deployed in Cisco 7600
Series Routers at WAN edges or in Catalyst 6500 Series Switches connected to WAN routers.
Figures 3 and 4 highlight two model deployments of Cisco NAM in the campus for performance
and voice monitoring.
