We are using LACP and it works fine except that the "error-drop"
statistics are increased for each LACP packet that arrives. We see this
behavior both for VPP 19.08 and for the current master branch.
Here is an example of a packet trace for a LACP packet:
00:00:16:717846: rdma-input
rdma: Interface101 (3) next-node bond-input
00:00:16:717848: bond-input
src [...], dst [...], Interface101 -> Interface101
00:00:16:717849: ethernet-input
SLOW_PROTOCOLS: [...]
00:00:16:717850: lacp-input
Interface101:
Length: 110
LACPv1
Actor Information TLV: length 20
[... LACP info here ...]
Partner Information TLV: length 20
[... LACP info here ...]
00:00:16:717851: error-drop
rx:Interface101
00:00:16:717852: drop
lacp-input: good lacp packets -- cache hit
So it says "good lacp packets" but at the same time "error-drop" which
seems contradictory.
LACP is in fact working fine, the only issue we have is the "error-
drop" statistics that we would like to avoid if there is in fact
nothing wrong.
Is there some reason why it is desirable to report error-drop for all
LACP packets, or is this something that can be fixed so that error-drop
is only used when there is something wrong?
Best regards,
Elias
