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] [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, E-Series only) Enter the keyword log to log the packets.
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, see the “Flow-based Monitoring” in the Port Monitoring section in the Dell EMC Networking OS Configuration Guide.

Usage Information

When you use the log option, the CP processor logs detail the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets’ details.

NOTE: When you configure ACL logging and byte counters simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead.
