Administrator Guide

If no access-list is attached to the interface, no information displays and you are returned to the DELL# prompt.
Example

mac access-list standard mac
seq 5 permit 11:22:33:44:55:66 count
seq 10 deny any log threshold-in-msgs 10 interval 5 order 1

Standard MAC ACL Commands
The following commands configure standard MAC ACLs. The C9000 supports both Ingress and Egress MAC ACLs.
When you create an access control list without any rule and then apply it to an interface, the ACL behavior reflects implicit permit.
NOTE: For more information, also refer to the Commands Common to all ACL Types and Common MAC Access List
Commands sections.
deny
To drop packets with a matching MAC address, configure a filter.
C9000 Series
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 include ACL messages in the log.
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. For more information, refer to the “Flow-based Monitoring” section
in the Port Monitoring chapter of the Dell Networking OS Configuration Guide.
