Re: [vpp-dev] Regarding buffers-per-numa parameter

[chetan bhasin]

Bottom line is stable/vpp 908 does not work with higher number of buffers
but stable/vpp2001 does. Could you please advise which area we can look at
,as it would be difficult for us to move to vpp2001 at this time.

Re: [vpp-dev] sh hardware-interfaces extended stats are not showing up

[carlito nueno]

Hi Damjan,

Sorry for the late reply. I tested it on v20.01 and this is now working.

Thanks!

 Even I am using vpp 19.08 & don’t see the extended stats which I used
 to see in other vpp release .
 There was not change in the configuration but with vpp 19.08 it’s not
 showing up .

 When I use dpdk application called testpmd the extended stats just show
 up fine . It’s only the vpp not showing it .

 Do we need to configure any thing to get it ?

 Note : In the release note of 19.08 I saw some changes gone in for
 extended stats .

 Thanks
