PRs:

sonic-net/sonic-sairedis#510
sonic-net/sonic-swss-common#303
sonic-net/sonic-utilities#529
sonic-net/sonic-swss#1716

The documents decribes the functional spec and high level design for Layer 2 Forwarding Enhancements.

All CLA requirements met.

Changed FDB flush mechanism from individual FDB entry delete to Bulk flush in hardware.

Updated to exclude bridge_port_id in Orchagent FDB data structure as it is not needed for bulk flush. We only need the FDB type.

some minor corrections.

Could you also help to fix CLI "show mac" takes too much time to display mac entries, e.g. It will take more than 30+ mins to display 32K entries output? Thanks!

Hi Wilson, We are able to bring this time down significantly. We will share the fix with community. Thanks. Anil

That's great! Thanks Anil!

1. Added per port per VLAN fdb clear option. 2. Listed all the SAI attributes being used. 3. Added -w option in VLAN Range commands to indicate logging of warning messages.

Hi Anil,

Are there any plans to write ansible or pytest scripts to test those enhancements. @anilkpandey

Thanks.
william-zx

anilkpandey · 2019-12-18T23:42:40Z

Hi William,

pytest scripts are added as part of the following PR:

sonic-net/sonic-swss#885

William-zx · 2019-12-19T07:40:51Z

Hi Anil,

It seems you have added some VS tests to test this enhancements. I also want to know if there are any plans to write test cases for this enhancements in sonic-mgmt

Thanks.
william-zx

anilkpandey · 2019-12-20T05:38:45Z

No, only VS pytest.

William-zx · 2019-12-20T09:48:21Z

Thanks Anil! I see.

+**Changes for Static FDB configuration.**
+New CLI will be added for configuring Static FDB entry. It will be set in the FDB_TABLE in CONFIG_DB. Vlanmgr will handle the CONIG_DB changes, do necessary validations and then populate in APP_DB. FdbOrch already has all the necessary handling for Static FDB changes from APP_DB.


I am curious When a static FDB entry is removed from CLI, will SAI notify a SAI_FDB_EVENT_AGED to orchagent?

From images/staticMacConfig.jpg, even if such an event is present, orchagent will ignore it

yes, SAI_FDB_EVENT_AGED will be received and it will be ignored at orchagent because the fdb entry does not exist anymore.
