Information
When you use the log option, the 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.

Parameters
Version 8.1.1.0 Introduced on E-Series ExaScale
Version 7.6.1.0 Support added for S-Series

Note: When ACL logging and byte counters are configured simultaneously, byte
counters may display an incorrect value. Configure packet counters with logging
instead.
deny Configure a filter to drop traffic based on the MAC address.
seq Configure a filter with specific sequence numbers.
sequence-number
Enter a number as the filter sequence number.
Range: zero (0) to 65535.
deny Enter the keyword deny to drop any traffic matching this filter.
permit
Enter the keyword permit to forward any traffic matching this
filter.
any Enter the keyword any to filter all packets.
host mac-address
Enter the keyword host followed by a MAC address to filter
packets with that host address.
mac-source-address
Enter the source MAC address in nn:nn:nn:nn:nn:nn format.
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.
mac-source-address-mask
Specify which bits in the MAC address must be matched.
mac-destination-address
Enter the destination MAC address and mask in
nn:nn:nn:nn:nn:nn format.
mac-destination-address-mask Specify which bits in the MAC address must be matched.
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.
