You can also use the TTL and IP options counters to monitor the performance of the Layer 3 forwarding
engine.
This example shows how to use the show mls statistics command to display packet statistics and errors
associated with the Layer 3 forwarding engine:

Monitoring Dropped Packets Using VACL Capture
The VACL capture feature allows you to direct traffic to ports configured to forward captured traffic. The
capture action sets the capture bit for the forwarded packets so that ports with the capture function
enabled can receive the packets. Only forwarded packets can be captured.
You can use VACL capture to assign traffic from each VLAN to a different interface.
VACL capture does not allow you to send one type of traffic, such as HTTP, to one interface and another type
of traffic, such as DNS, to another interface. Also, VACL capture granularity is only applicable to traffic
switched locally; you cannot preserve the granularity if you direct traffic to a remote switch.
