Secure solution
Offers TACACS+, Secure Sockets Layer (SSL), and Secure Shell (SSH) Protocol–based security.
Standards-based northbound interface
Facilitates the export of data to other tools and devices that build additional value on top of NAM. For
example, NAM can export application response time information to NetQoS SuperAgent for
consolidated networkwide performance reporting.

Deployment flexibility
Cisco NAM can be deployed in blade form factor in Cisco Catalyst 6500 Series Switches, Cisco
7600 Series Routers, and Cisco Integrated Services Routers as multigigabit appliances, and as a
virtual blade residing directly on WAAS devices. The complement of physical and virtual blades and
of appliances allows NAM instrumentation to be broadly deployed in the network for comprehensive
performance monitoring.

Q.
What is the difference between NAM-1 and NAM-2?
A.
NAM-1 and NAM-2 share the same hardware architecture and software applications, but differ in the following
ways:
●
NAM-2 has an additional accelerator card that provides extra high packet processing performance to monitor
gigabit bandwidth.
●
With NAM software 3.1 or later, NAM-2 includes two data ports to support Switched Port Analyzer
(SPAN)/VLAN Access Control List (VACL) traffic, whereas NAM-1 includes one data port only. With the
second data port, the NAM-2 can receive two SPAN sessions, two VACL-based captures, or one of each data
source. The SPAN sessions, each consisting of multiple ports, VLANs, or EtherChannel connections, can be
used independently or together. This feature allows users to view traffic on each side of a full-duplex trunk or
to dedicate one data port for troubleshooting and the other data port for reporting.
●
NAM-2 has a larger capture buffer than NAM-1. The buffer capacity of NAM-2 (WS-SVC-NAM-2-250S) is 500
MB and NAM-1 (WS-SVC-NAM-1-250S) is 200 MB.
Q.
Is the NAM-1 upgradeable to NAM-2?
A.
No. NAM-1 and NAM-2 have fixed configurations and cannot be transformed from one version to the other.
Q.
What is the Cisco NAM Traffic Analyzer?
A.
The Cisco NAM includes embedded Traffic Analyzer software that analyzes and stores the collected data using
standards-based MIBs and extensions (remote monitoring [RMON], DiffServ monitoring [DSMON], switch
monitoring [SMON], application response time monitoring, and VoIP monitoring). The Cisco NAM also hosts an
embedded web server that presents the configuration menus and traffic reports to clients using a supported web
browser. These reports provide visibility into voice, video, and data traffic.
