Usage
Information
When you use the log option, the CP processor logs detail 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.
