Reference Guide

When you use the log option, the CP processor logs details the packets that match.
Depending on how many packets match the log entry and at what rate, the CP may become
busy as it has to log these packets’ details.
NOTE: When ACL logging and byte counters are configured simultaneously, byte counters
may display an incorrect value. Configure packet counters with logging instead.
