Using a VACL as a Traffic Source
This section describes how to configure a VACL for a switch running Cisco IOS Release 12.1(13)E1 or
later releases. To configure a LAN VACL on the Catalyst operating system, you can use the security ACL
feature to achieve the same result. For more information, see the “Operating-System-Independent
Configuration” procedure on page 3-12.
Configuring a VACL on a WAN Interface
Because WAN interfaces do not support SPAN if you want to monitor traffic on a WAN interface using
a NAM, you need to manually configure a VACL on the switch using the switch CLI. This feature only
works for IP traffic over the WAN interface. You can apply additional filtering rules to target specific
data flows.
In addition, you can use a VACL if there are no available SPAN sessions to direct traffic to the NAM. In
this scenario, you can set up a VACL instead of SPAN for monitoring VLAN traffic.
The following examples describe the steps to configure a VACL for a switch running Cisco IOS
Release 12.1(13)E1 or higher. To configure a LAN VACL on a switch running the Catalyst operating
system, use the ACL feature to achieve the same result.
