Esm - Lag Hashing Per Vport - Alcatel-Lucent 7750 Configuration Manual

LAG and ECMP Hashing
•
Operators may sometimes require the capability to query the system for the link in a LAG or
Ethernet tunnel that is currently assigned to a given service-id or ISID. This ability is provided
using the tools>dump>map-to-phy-port {ccag ccag-id | lag lag-id | eth-tunnel tunnel-index}
{isid isid [end-isid isid] | service servid-id | svc-name [end-service service-id | syc-name]}
[summary] command.
A sample usage is as follows:
A:Dut-B# tools dump map-to-phy-port lag 11 service 1
ServiceId
---------- ------------- --------------
1
A:Dut-B# tools dump map-to-phy-port lag 11 isid 1
ISID
-------- -----------------------

A:Dut-B# tools dump map-to-phy-port lag 11 isid 1 end-isid 4
ISID

ESM – LAG Hashing per Vport
Background
Vport is a 7x50 BNG representation of a remote traffic aggregation point in the access network. It
is a level in the hierarchical QoS model implemented within the 7x50 BNG that requires QoS
treatment.
When 7x50 BNG is connected to access network via LAG, a VPort construct within the BNG is
instantiated per member link on that LAG. Each instance of the Vport in such a configuration
receives the entire amount of configured bandwidth. When traffic is sprayed in a per-subscriber

−
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
