Service Manual

The Switch supports both Ingress and Egress MAC ACLs.
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]]
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.
Defaults Not configured.
