Note
If a NAM is installed, you do not need to specify an external data collector with a
set mls nde
collector_ip
[
udp_port_number
] command as described in the
Catalyst 6000 Family Software
Configuration Guide
. Ignore messages that the host and port are not set.
Using SPAN as a Traffic Source
Note
You can configure SPAN as a traffic source using both the CLI and the NAM Traffic Analyzer
application.
To direct SPAN traffic to the NAM for monitoring, you must configure port 1 on the NAM module as
the SPAN destination port.
Note
You cannot use NAM ports as SPAN source ports.
The NAM can analyze Ethernet traffic from Ethernet, Fast Ethernet, Gigabit Ethernet, trunk ports, or
Fast EtherChannel SPAN source ports. You also can specify an Ethernet VLAN as the SPAN source.
You can use RSPAN traffic as a SPAN source for the NAM. Verify that the SPAN source is set to the
same VLAN ID that is used for RSPAN. The SPAN destination should be set to
nam_module/1
.
For more information on configuring SPAN and RSPAN, refer to the switch software configuration
guide
.
To set the NAM as a SPAN destination port, perform this task in privileged mode:
Note
The SPAN destination for the NAM must always be port 1.
