Usage 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.
NOTE: When you congure the ACL logging and byte counters simultaneously, byte counters may
display an incorrect value. Congure packet counters with logging instead.
Related Commands
deny — congures a MAC ACL lter to drop packets.
seq —congure a MAC ACL lter with a specied sequence number.
seq
To a deny or permit lter in a MAC access list while creating the lter, assign a sequence number.
Syntax
seq sequence-number {deny | permit} {any | mac-source-address [mac-source-
address-mask]} [count [byte]] [log] [monitor] [no-drop]
To remove this lter, use the no seq sequence-number command.
Parameters
sequence-number Enter a number from 0 to 65535.
deny Enter the keyword deny to congure a lter to drop packets meeting this
condition.
permit Enter the keyword permit to congure a lter to forward packets meeting this
criteria.
any Enter the keyword any to lter all packets.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
(OPTIONAL) Specify which bits in the MAC address must match. If no mask is
specied, a mask of 00:00:00:00:00:00 is applied (in other words, the lter allows
only MAC addresses that match).
count (OPTIONAL) Enter the keyword count to count packets the lter processes.
byte (OPTIONAL) Enter the keyword byte to count bytes the lter processes.
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 trac
that you want to monitor and the ACL in which you are creating the rule is applied
to the monitored interface.
