permit

To pass packets matching the criteria specified, configure a filter.

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.
byte
(OPTIONAL) Enter the keyword byte to count bytes the filter processes.
log
(OPTIONAL, E-Series only) Enter the keyword log to log the packets.
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.
NOTE: For more information, see Flow-based Monitoring in the “Port Monitoring” section of the Dell EMC Networking OS Configuration Guide.

Usage Information

When you use the log option, the CP processor logs details about the packets that match. Depending on how many packets match the log entry and at what rate, the CP may become busy as it has to log these packets’ details.

NOTE: When you configure the ACL logging and byte counters simultaneously, byte counters may display an incorrect value. Configure packet counters with logging instead.
Related Commands
  • deny — configure a MAC ACL filter to drop packets.
  • seq — configure a MAC ACL filter with a specified sequence number.
