deny
To drop packets that match the filter criteria, configure a filter.
Syntax
deny {any | host mac-address | mac-source-address mac-source-address-mask}
{any | host mac-address | mac-destination-address mac-destination-address-
mask} [ethertype-operator] [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 | host mac-address | mac-source-address mac-source-
address-mask} {any | host mac-address | mac-destination-address mac-
destination-address-mask} command.
Parameters
any Enter the keyword any to drop all packets.
host mac-
address
Enter the keyword host and then enter a MAC address to drop packets with that
host address.
mac-source-
address
Enter a MAC address in nn:nn:nn:nn:nn:nn format.
mac-source-
address-mask
Specify which bits in the MAC address must match.
The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows
entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that
match exactly.
mac-destination-
address
Enter the destination MAC address and mask in nn:nn:nn:nn:nn:nn format.
mac-destination-
address-mask
Specify which bits in the MAC address must match.
The MAC ACL supports an inverse mask; therefore, a mask of ff:ff:ff:ff:ff:ff allows
entries that do not match and a mask of 00:00:00:00:00:00 only allows entries that
match exactly.
ethertype
operator
(OPTIONAL) To filter based on protocol type, enter one of the following
Ethertypes:
● ev2 - is the Ethernet II frame format
● llc - is the IEEE 802.3 frame format
● snap - is the IEEE 802.3 SNAP frame format
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, refer to the “Flow-based
Monitoring” section in the Port Monitoring chapter of the Dell Networking OS
Configuration Guide.
