How to create a recycle port with SAI?

ysmanman · 2021-03-03T17:21:27Z

How to create a recycle port with SAI?

This should be similar to front panel ports. Recycle ports are defined in port_config.ini, and are populated in APP_DB port table. portsorch retrieves ports list, including recycle ports, from SAI in initialization, and initialize recycle ports just like other front panel ports in doTask.

how to convey to ASIC SAI implementation that this is not an actual front-panel port, but to add 1 or 2 recycle ports?

If a SAI implementation needs to differentiate recycle port from recycle ports, it can encode a sub port type in the pid of recycle port. But this is transparent to orchagent since all orchagent needs is just a pid for recycle port.

Some Question on QoS w.r.t Recycle Port:-

What about the Queue of recycle port ? Do we will have Queue stats for recycle port ? What will be behaviour of PFC and recycle port ? Can this port get back pressure for PFC queue 3 and 4 ?

The naming convention for inband ports is "Ethernet-IB0", "Ethernet-IB1" etc. Can you please change "Ethernet-Rec1" above to "Ethernet-IB0"

Sounds good. Fixed.

Recycle port is expected to have queue statistics like any other port.
The back pressure part may be implementation dependent. Expect more clarity on that once the Recycle port proposal is reviewed in the SAI forum.

QOS for the recycle port in general works similar any other port. It will support queues, mappings, remarking etc.

I would like to request that we add to the doc the usage of the SAI recycle port API - the current raised idea is to add a subport type for the recycle port. How will this be used by the sonic applications/users?

The HLD proposes to use recycle port in a way that’s independent of the SAI recycele port API. In this proposal, SONiC application/users shouldn’t really care about if a subport type is defined for recycle port or not. What we proposed in the HLD is to use port role to identify recycle ports in SONiC and its applications. Detailedly, we define recycle ports by setting the specific port roles along with their lanes in port_config.ini. With lanes and roles from port_config.ini, portsorch should be able to initialize recycle ports and also uncover their pid returned by SAI. SONiC applications that need recycle ports, like Everflow, should simply request the pid of recycle port from portsorch. It’s not clear to me why we have to define a subport type for recycle port. Did I get your comment correct?

As I replied to another comment, this seems not relevant to the proposal in the HLD.

@ysmanman can we capture this point as part of document also.
