Administrator Guide

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.
