PW hash-label generation for 7210 SAS-R6 and 7210 SAS-R12

The following notes apply to Table: Packet fields used for PW hash-label generation on the 7210 SAS-R6 and 7210 SAS-R12:

• Source and destination MAC addresses are from the outermost Ethernet header.

• MPLS and PBB traffic always use a fixed hash value. MPLS and PBB traffic encapsulation is identified by the system, only if the outermost Ethernet has two or fewer VLAN tags. If there are more VLAN tags, the system identifies the traffic as ‟Any other traffic”.

• For IP traffic with two or more VLAN tags, source and destination MAC and VLAN are used to generate the hash label.

• Any other traffic with three or more VLAN tags uses source and destination MAC and VLAN to generate the hash label.

• The value of a hash label generated for the packet is the same and is not influenced by the configuration of the load-balancing algorithm using the command configure>lag>load-balancing.

• Traffic identified as ‟All Other Traffic” have Ethertype or may not have Ethertype (for example, xSTP traffic does not have Ethertype). Ethertype is used only if available in the outermost Ethernet header for packets with two or fewer VLAN tags.
