- Is this feature supported on SUP ?
- Please share CLI command as well as o/p.
- Please explain how aggregation of VoQ Stats from multiple LCs happening here. As VoQ id may be same across multiple LCs, it may end up over-writing existing data.
- please try reading the queue counters from LC while this polling is happening to make sure LC queue counter show is not impacting SUP o/p.
|
@vivekverma-arista Can you please do test to send traffic from multiple sources to single destination and see if the aggregation is happening properly in the CLI o/p ? |
|
Also, Can we have command format like - show queue counter --voq as it will be in-line with following - show queue counters |
|
please rebase and bring to latest. |

@saksarav-nokia please review as well |

We support getting the voq stats locally at the linecard level, can we update the chassis_db when the voq stats are updated locally on the linecard? why we another timer and get the stats again to update to the chassis?
This reverts commit cb6b968.
This reverts commit fe29d7c.
Create voq to port name map during port initializa Why I did it? When ports are getting created and voq's are being assigned to them, create a voq to port name map table in counter DB so that it is easy to find the port name for a specific voq when creating an entry in chassis_app_db to calculate agg voq counters.
|
Please update the code as it is out of date. @viveksrao-arista, Is this change to maintain mapping of VoQ to system port ? To be needed while updating the data to chassis_app_db ? |
Yes, this table maps a VoQ to system port and is used to obtain the interface name to which the VoQ belongs to when updating chassis_app_db. |
|
@viveksrao-arista please rebase it. |
Rebased the code. |
What I did
Implemented aggregate VOQ counters support according to aggregate VOQ counters HLD #1578
Why I did it
Part of aggregate VOQ counter feature support #1543
How I verified it
Sent traffic to the switch and checked that VOQ stats are getting populated in CHASSIS_APP_DB
