deny ether-type (for Extended MAC ACLs)
Congure an egress lter that drops specied types of Ethernet packets on egress ACL supported line cards. (For more information,
refer to your line card documentation).
Syntax
deny ether-type protocol-type-number {destination-mac-address mac-address-
mask | any} vlan vlan-id {source-mac-address mac-address-mask | any} [count
[byte]] [order] [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 ether-type protocol-type-number {destination-mac-address
mac-address-mask | any} vlan vlan-id {source-mac-address mac-address-
mask | any} command.
Parameters
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 time interval range is from 1 to 10
minutes.
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.
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 ve minutes. By default, ow-based monitoring is
not enabled.
