Dell C9000 series, Reference Manual

Page: 351 / 2286

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 of the C9000 Series 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.

Commands
deny — configures a filter to drop packets.
permit — configures a filter to forward packets.
IP Prefix List Commands
When you create an access-list without any rule and then apply it to an interface, the ACL behavior reflects
implicit permit.
To configure or enable IP prefix lists, use these commands.
clear ip prefix-list
Reset the number of times traffic meets the conditions (“hit” counters) of the configured prefix lists.
