dynamic_th failed because redis sends unchanged field to orchagent when updating dynamic_th #3971
Description
Description
It's impossible to change dynamic_th value for lossless buffer profile which has been applied to some ports on the fly.
Describe the results you expected:
It should be eligible to change dynamic_th parameter on the fly.
Describe the results you received:
- The new value for dynamic_th is not offloaded to hardware.
- There are errors in syslog:
Jan 2 19:00:31.799935 sonic ERR swss#orchagent: :- meta_generic_validation_set: SAI_BUFFER_PROFILE_ATTR_POOL_ID:SAI_ATTR_VALUE_TYPE_OBJECT_ID attr is create only and cannot be modified
Jan 2 19:00:31.799935 sonic ERR swss#orchagent: :- processBufferProfile: Failed to modify buffer profile, name:pg_lossless_10000_5m_profile, sai object:190000000002f4, status:-5
Jan 2 19:00:31.799935 sonic ERR swss#orchagent: :- doTask: Failed to process buffer task, drop it
Steps to reproduce the issue:
- Install Master branch image on a switch.
- Configure qos:
config qos reload - Compose a json file for changing buffer parameter
dynamic_thfor lossless buffer which has been applied to some ports:
{
"BUFFER_PROFILE": {
"pg_lossless_10000_5m_profile": {
"dynamic_th": "2",
"pool": "[BUFFER_POOL|ingress_lossless_pool]"
}
}
}
- Try to change dynamic_th for lossless buffer profile on the fly:
sonic-cfggen -j ./buf_prof4.json --write-to-db
