When you use the log option, CP processor logs details about 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.

Commands
Extended MAC ACL Commands
When an access-list is created without any rule and then applied to an interface, ACL behavior reflects
implicit permit.
c and s platforms (except the S4810 system) support Ingress MAC ACLs only.
The and Z9000 support both Ingress and Egress MAC ACLs.
The following commands configure Extended MAC ACLs.
• deny
mac-source-address-mask
(OPTIONAL) Specify which bits in the MAC address must match. If
no mask is specified, a mask of 00:00:00:00:00:00 is applied (in other
words, the filter allows only MAC addresses that match).
count (OPTIONAL) Enter the keyword count to count packets processed
by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by
the filter.
log (OPTIONAL, E-Series only) Enter the keyword log to log the
packets.
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 will be applied to the monitored interface.
For details, see the section “Flow-based Monitoring” in the Port
Monitoring chapter of the FTOS Configuration Guide.
