Chapter 3 Getting Started
Configuring Traffic Sources for Capturing NAM Traffic
To enable SPAN on the NAM, perform one of these tasks:
This example shows how to enable SPAN on the NAM:
Router# show monitor
Session 1
---------
Source Ports:
RX Only: None
TX Only: None
Both: None
Source VLANs:
RX Only: None
TX Only: None
Both: None
Destination Ports:None
Filter VLANs: None
Session 2
---------
Source Ports:
RX Only: None
TX Only: None
Both: None
Source VLANs:
RX Only: None
TX Only: None
Both: None
Destination Ports:None
Filter VLANs: None
Router# configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)# monitor session 1 source vlan 1 both
Note If you are using the switch CLI to configure SPAN as a traffic source to NAM-1, the SPAN destination
port for NAM-1 is data-port 1. The SPAN destination ports for NAM-2 is data-port 1 and data-port 2.
Command Purpose
Router (config)# monitor session {session_numbe r}
{source {interface type
slot/por t} | {vlan vlan_I D}}
[, | - | rx | tx | both]
Sets the source interfaces and
VLANs for the monitor session.
Router (config)# monitor session { session_numbe r}
{destination analysis module
NAM module number
data-port port }
Enables port 1 of the NAM as a
SPAN destination.
Router (config)# no monitor session session_number
Disables the monitor session.
Router (config)# monitor session {session_numbe r}
{filter
{vlan_I D} [, | - ]}
Filters the SPAN session so that only
certain VLANs are seen from switch
port trunks.
Router # show monitor session { session_numbe r}
Shows current monitor sessions.
