The following table describes the packet fields used for hashing for services configured on the 7210 SAS-R6 and 7210 SAS-R12.
The following notes apply to Table: LAG hashing algorithm for services and traffic flows configured on the 7210 SAS-R6 and 7210 SAS-R12:
The term ‟service_id” refers to the service ID of the egressing VPLS, Epipe, IES, or VPRN service.
The term ‟lag_index” refers to the Lag-IfIndex of the egressing lag.
the terms ‟encap_value” and ‟service_vlan” are based on the inner and outer VLAN values of the egressing LAG SAP.
The term ‟sap_index” is a value assigned uniquely for each SAP internally.
Parameters used for LAG hashing are the same in both SAP egress queue mode (SAP-based egress scheduling) or port egress queue mode (port-based egress scheduling), unless otherwise specified.
The term ‟learned” corresponds to the destination MAC.
The term ‟source and destination MAC” refers to customer source and destination MACs, unless otherwise specified.
In the case of a LAG with two ports at egress, different ingress port IDs may result in the same hash index, which causes traffic to always get hashed to only one of the ports. Load balancing is expected to occur when there are more than 2 ports in the lag.
The term ‟mgid” is the multicast group ID and is a software-allocated number. A unique number is allocated for each Layer-2 multicast MAC address.
The 7210 SAS supports Layer-2 multicast in a VPLS service. A group of 32 multicast IP addresses map to a single Layer-2 multicast MAC address. The ‟mgid” parameter remains the same for all IP multicast addresses that map to the same Layer-2 multicast MAC address.
