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 keyword
log
to enable the triggering
of ACL log messages.
threshold-in-
msgs
count
(OPTIONAL) Enter the
threshold-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.
