CiscoLive Barcelona 2010
Cisco Network Analysis Module (NAM) improves operational efficiency at the CiscoLive event by providing
in-depth analysis of traffic statistics, application performance, and voice quality.
Business Challenge
Unlike traditional corporate networks, the CiscoLive network is built up
and fully operational in a matter of days. The CiscoLive network offers
many advanced services including Cisco TelePresence
™
, video
surveillance, IPv6, and voice over IP. The network provides
connectivity for the various Cisco and partner technology
demonstrations, labs, streaming video of the technical sessions, and wireless access for all the attendees. With so
many activities dependent on the network, the availability, reliability, and performance of the network are crucial to
the success of the event. Hence, from a network operations perspective, visibility into network usage and
performance is critical.
Solution and Results
The Cisco NAM SVC-NAM-2 service module running NAM 4.1 software was installed in the core Catalyst
®
6500
Switch to deliver granular traffic analysis, rich application performance measurements, comprehensive voice quality
monitoring, and deep insightful packet captures to help monitor and troubleshoot network performance. See Figure

The CiscoLive network had 42 VLANs configured. There were different VLANs for users, partners, demos, labs,
voice, wireless, management, and so on. Traffic from all 42 VLANs, with a total of about 300 Mbps, was set up to be
sent through the Switched Port Analyzer (SPAN) to the NAM for analysis using the integrated data source
configuration menu available in the NAM web-based GUI. Various monitoring capabilities, such as core monitoring,
voice and RTP steam monitoring, response time monitoring, Differentiated Services (DiffServ) monitoring, URL
monitoring, and chassis parameter (switch health and port stats) monitoring was enabled on the NAM. The NAM
