c-tag-cos

 

c-cos-value

: Specified 802.1p priority in the internal 802.1QTag carried 

by the packet. Specify the same value for the 

c-cos-value

 and 

cos-value

 

parameters.

protocol-type

: This parameter is used to specify the protocol type carried by the 

Ethernet frame. The protocol type can be expressed by either a name or a 
hexadecimal number. When the protocol type is expressed by a name, the value 
can be arp, ip, ipv6, mpls, nbx, pppoe-control, pppoedata and rarp. When the 
protocol type is expressed by a hexadecimal number, the range is 1-FFFF.

source-vlan-id

source-vlan-id-end

 ] shows its source VLAN or source 

VLAN range (identified by the external VLAN Tag of the packet ). 

source-mac-addr

 

source-mac-wildcard

 shows source MAC address and wildcard of the source 

address. The two parameters jointly determine the range of the source MAC 
addresses in which the user is interested. The smaller the wildcard, the smaller the 
range of the MAC address. For example, 00e0-fc01-0101 0-0-0 specifies a MAC 
address: 00e0-fc01-0101, but 00e0-fc01-0101-0-0-fff specifies an address range: 
00e0-fc01-0000 to 00e0-fc01-ffff.

c-tag-vlan

 

c-tag-vlanid

: Indicates the system identifies the source VLAN according 

to the information about VLAN ID in the internal 802.1QTag carried by the packet.

dest-mac-addr

 

dest-mac-wildcard

 shows destination MAC address and 

wildcard of the destination address. The two parameters work together to 
determine the range of the destination MAC addresses in which the user is 
interested. The smaller the wildcard, the smaller the range of the MAC address. 
For example, 00e0-fc01-0101 0-0-0 specifies a MAC address: 00e0-fc01-0101, 
but 00e0-fc01-0101-0-0-fff specifies an address range: 00e0-fc01-0000 to 
00e0-fc01-ffff.
