I really don’t have
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.

Thanks Damjan for the reply!
Following are my observations on Intel X710/XL710 pci-
1) I took latest code base from stable/vpp19.08 : Seeing error as "
*ethernet-input
l3 mac mismatch*"
*With Buffers 537600*
*vpp# show
buffers
|Pool NameIndex NUMA Size Dat
Shouldn’t be too hard to checkout commit prior to that one and test if problem
is still there…

Mbuf's are 2KB's, not 2 MB's (that's the huge page size)
But the fact remains that my usecase is unstable at higher configured
buffers but is stable at lower values like 10 (this can by all
means be my usecase/code specific issue)
If any
Hi,
I am using DPDK Plugin with VPP19.08.
When I set the buffers-per-numa parameter to a high value, say,
25, I am seeing crashes in the system.
(The corresponding parameter controlling number of mbufs in VPP18.01
used to work well. This was in dpdk config section as num-mbufs)
I quickly che
