permit
To pass packets matching the criteria specified, configure a filter.
C9000 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 [interval minutes]
[threshold-in-msgs [count]] [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.
byte (OPTIONAL) Enter the keyword byte to count bytes the filter processes.
log (OPTIONAL) Enter the keyword log to include ACL messages in the log.
threshold-in
msgs count
(OPTIONAL) Enter the threshold-in-msgs keyword followed by a value to
indicate the maximum number of ACL logs that can be generated, exceeding which
the generation of ACL logs is terminated with the seq, permit, or deny
commands. The threshold range is from 1 to 100.
interval minutes (OPTIONAL) Enter the keyword interval followed by the time period in minutes
at which ACL logs must be generated. The threshold range is from 1 to 10 minutes.
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.
