Chapter 5 Troubleshooting the Network Analysis Module

Local Interfaces in the NAM ifTable

This section explains the differences between the newer NAM-1 and NAM-2 and the previous version

of the WS-X6380-NAM. The three versions of the Network Analysis Module (NAM) are as follows:

• WS-X6380-NAM

• WS-SVC-NAM-1

• WS-SVC-NAM-2

The WS-X6380-NAM appears in the supervisor engine CLI and ifTable as two ports. The first port, the

data port, is used for receiving SPAN traffic. The second port is the management port. On the NAM, these

two ports show up in the ifTable as the first two ports (with ifIndex.1 for data and ifIndex.2 for

management).

The WS-SVC-NAM-1 appears in the supervisor engine CLI (in the Catalyst operating system) and

ifTable as three ports. The first port is unused. The second port is the management port. The third port

is the data port (for receiving SPAN traffic). The supervisor engine CLI (in Cisco IOS software) parses

the ports to (“analysis module . . .”). On the NAM's ifTable, the management port appears as the first

port (ifIndex.1) and the data port appears as the second (ifIndex.2).
