Overview of the NAM Platforms

SNMP v3 Support -- NAM to Router/Switch Support

Simple Network Management Protocol Version 3 (SNMPv3) is an interoperable standards-based
protocol for network management. The security features provided in SNMPv3 are:
• Message integrity—Ensuring that a packet has not been tampered with in-transit.
• Authentication—Determining the message is from a valid source.
• Encryption—Scrambling the contents of a packet prevent it from being seen by an unauthorized
source.
With NAM 5.0, you have the ability to manage devices with SNMPv3.
Note For the WS-SVC-NAM-1 and WS-SVC-NAM-2 platforms, SNMPv3 is not required. SNMP requests
and responses are communicated over an internal interface within the chassis, and SNMPv3 is not used.
Overview of the NAM Platforms
The following models differ in memory, performance, disk size, and other capabilities. Therefore, some
allow for more features and capabilities (for example, the amount of memory allocated for capture).
Throughout this User Guide, there will be Notes explaining that some features apply only to specific
platforms. If there is no Note, then that feature or aspect applies to all NAM platforms.
