permit
To pass packets matching the criteria specified, configure a filter.
S4820T
Syntax
permit {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 permit {any | host mac-address | mac-source-address
mac-source-address-mask} {any | mac-destination-address mac-
destination-address-mask
} command.
Parameters
any Enter the keyword any to forward all packets.
host Enter the keyword host then a MAC address to forward
packets with that host address.
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.
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 be matched.
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 the
filter processes.
