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
deny {any | mac-source-address [mac-source-address-mask]} [count [byte]]
[log [interval minutes] [threshold-in-msgs [count]] [monitor]
To remove this lter, you have two choices:
• Use the no seq sequence-number command if you know the lter’s sequence number.
•
Use the no deny {any | mac-source-address mac-source-address-mask} command.
Parameters
any Enter the keyword any to specify that all routes are subject to the lter.
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 processed by the lter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by the lter.
log (OPTIONAL) Enter the keyword log to include ACL messages in the log.
