per-service-hashing
Syntax [no] per-service-hashing
Context config>service>vpls
Description This command enables on a per service basis, consistent per-service hashing for Ethernet services
over LAG, over Ethernet tunnel (eth-tunnel) using loadsharing protection-type or over CCAG.
Specifically, it enables the new hashing procedures for Epipe, VPLS, regular or PBB services.
The following algorithm describes the hash-key used for hashing when the new option is enabled:
• If the packet is PBB encapsulated (contains an I-TAG ethertype) at the ingress side, use the ISID
value from the I-TAG
• If the packet is not PBB encapsulated at the ingress side
– For regular (non-PBB) VPLS and EPIPE services, use the related service ID
– If the packet is originated from an ingress IVPLS or PBB Epipe SAP
•If there is an ISID configured use the related ISID value
•If there is no ISID yet configured use the related service ID
– For BVPLS transit traffic use the related flood list id
•Transit traffic is the traffic going between BVPLS endpoints
•An example of non-PBB transit traffic in BVPLS is the OAM traffic
• The above rules apply regardless of traffic type
– Unicast, BUM flooded without MMRP or with MMRP, IGMP snooped
The no form of this command implies the use of existing hashing options.
