cos-bitmask
6
– Class-of-Service bitmask. (Range: 0-7)
ip precedence – IP Precedence value (Range: 0-7)
vid – VLAN ID. (Range: 1-4094)
vid-bitmask
6
– VLAN bitmask. (Range: 1-4095)
ethertype – A specific Ethernet protocol number. (Range: 0-ffff hex)
ethertype-bitmask
6
– Protocol bitmask. (Range: 0-ffff hex)
protocol - IP protocol or IPv6 next header. (Range: 0-255)
For information on next headers, see permit, deny (Extended IPv6 ACL).
sport
7
– Protocol source port number. (Range: 0-65535)
dport

Command Usage
◆ New rules are added to the end of the list.
◆ The ethertype option can only be used to filter Ethernet II formatted packets.
◆ A detailed listing of Ethernet protocol types can be found in RFC 1060. A few of
the more common types include the following:
■
0800 - IP
■
0806 - ARP
■
8137 - IPX
◆ If an Extended IPv4 rule and MAC rule match the same packet, and these rules
specify a “permit” entry and “deny” entry, the “deny” action takes precedence.
6. For all bitmasks, “1” means relevant and “0” means ignore.
7. Includes TCP, UDP or other protocol types.
