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 packet details.
By default, 10 ACL logs are generated if you do not specify the threshold explicitly.
The default frequency at which ACL logs are generated is five minutes. By default,
flow-based monitoring is not enabled.
Use the
monitor
option only when you are using flow-based monitoring. For
more information, refer to the Port Monitoring chapter in the
Z9500 Configuration
Guide
.
NOTE: When ACL logging and byte counters are configured simultaneously,
byte counters may display an incorrect value. Configure packet counters with
logging instead.
