Users Guide

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
protocol-type-
number
Enter a number from 600 to FFFF as the specic Ethernet type trac to drop.
destination-mac-
address mac-
address-mask
Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must match.
The MAC ACL supports an inverse mask; therefore, a mask of ::::: allows entries
that do not match and a mask of 00:00:00:00:00:00 only allows entries that match
exactly.
any Enter the keyword any to match and drop specic Ethernet trac on the interface.
vlan vlan-id Enter the keyword vlan and then enter the VLAN ID to lter trac associated with a
specic VLAN. The range is 1 to 4094 and 1 to 2094 for ExaScale ( you can use IDs 1 to
4094). To lter all VLAN trac, specify VLAN 1.
source-mac-
address mac-
address-mask
Enter a MAC address and mask in the nn:nn:nn:nn:nn format.
For the MAC address mask, specify which bits in the MAC address must match.
The MAC ACL supports an inverse mask; therefore, a mask of ::::: allows entries
that do not match and a mask of 00:00:00:00:00:00 only allows entries that match
exactly.
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.
order (OPTIONAL) Enter the keyword order to specify the QoS priority for the ACL entry. The
range is from 0 to 254 (where 0 is the highest priority and 254 is the lowest; lower order
numbers have a higher priority) If you did not use the keyword order, the ACLs have the
lowest order by default (255).
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 of 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.
