ACL statistics and rate limit counting

ACL statistics, also called ACL counting, enables the Dell device to count the number of packets
and the number of bytes per packet to which ACL filters are applied.
Rate limit counting counts the number of bytes and the conformance level per packet to which rate
limiting traffic policies are applied. The device uses the counting method similar to the two-rate
three-color marker (trTCM) mechanism described in RFC 2698 for adaptive rate limiting, and the
single-rate three-color marker (srTCM) mechanism described in RFC 2697 for fixed rate limiting.
Rate limit counting is automatically enabled when a traffic policy is enforced (active). You can view
these counters using the show commands listed in

Enabling ACL statistics

NOTE
ACL statistics and ACL counting are used interchangeably throughout this chapter and mean the
same thing.
Use the procedures in this section to configure ACL statistics. Before configuring ACL statistics, see
what to consider in
You also can enable ACL statistics when you create a traffic policy for rate limiting. Refer to
"Enabling ACL statistics with rate limiting traffic policies"
Complete the following steps to implement the ACL statistics feature.
1. Create a traffic policy. Enter a command such as the following.
2. Create an extended ACL entry or modify an existing extended ACL entry that references the
3. Bind the ACL to an interface. Enter commands such as the following.
The previous commands configure an ACL counting policy and apply it to port e4. Port e4 counts
the number of packets and the number of bytes on the port that were permitted or denied by ACL
filters.

Syntax: access-list <num> permit | deny.... traffic policy <TPD name>
Syntax: [no] ip access-group <num> in
NOTE
For brevity, some parameters were omitted from the access-list syntax.
