Reference Guide

permit
Configure a filter to pass packets matching the criteria specified.
C-Series, E-Series, S-Series, Z-Series
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 and then enter 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 processed
by the filter.
byte (OPTIONAL) Enter the keyword byte to count bytes processed by
the filter.
