Reference Guide
The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows
entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that
match exactly.
ethertype
operator
(OPTIONAL) To filter based on protocol type, enter one of the following
Ethertypes:
● ev2 - is the Ethernet II frame format.
● llc - is the IEEE 802.3 frame format.
● snap - is the IEEE 802.3 SNAP frame format.
count (OPTIONAL) Enter the keyword count to count packets the filter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
log (OPTIONAL) Enter the keyword log to include ACL messages in the log.
threshold-in
msgs
count
(OPTIONAL) Enter the threshold-in-msgs keyword followed by a value to
indicate the maximum number of ACL logs that can be generated, exceeding which
the generation of ACL logs is terminated with the seq, permit, or deny
commands. The threshold range is from 1 to 100.
interval
minutes
(OPTIONAL) Enter the keyword interval followed by the time period in minutes
at which ACL logs must be generated. The threshold range is from 1 to 10 minutes.
monitor (OPTIONAL) Enter the keyword monitor when the rule is describing the traffic
that you want to monitor and the ACL in which you are creating the rule is applied
to the monitored interface. For more information, refer to the “Flow-based
Monitoring” section in the Port Monitoring chapter of the Dell Networking OS
Configuration Guide.

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 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.
