● snap - is the IEEE 802.3 SNAP frame format
count (OPTIONAL) Enter the keyword count to count packets processed by the filter.

Commands
permit — configures a MAC address filter to pass packets.
seq — configures a MAC address filter with a specified sequence number.
deny
To drop packets with a the MAC address specified, configure a filter.
Syntax
deny {any | mac-source-address [mac-source-address-mask]} [count [byte]]
[log [interval minutes] [threshold—in-msgs [count]] [monitor]
To remove this filter, you have two choices:
● Use the no seq sequence-number command if you know the filter’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 filter.
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
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) Enter the keywordlog to enable the triggering of ACL log messages.
threshold-in-
msgs count
(OPTIONAL) Enter thethreshold-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.
Defaults 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.
