RX errors on wrp interface

Mille — Mon, 09 May 2022 14:26:08 GMT

Hi mate,

Any clue why I see RX errors on wrp interface?
It's on all my warp interfaces for each VS and on all my appliances in the cluster.
Version is R81.10 take 45.

# ip -s -s link show wrp1
34: wrp1: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UNKNOWN mode DEFAULT qlen 1000
link/ether 00:12:c1:66:a0:02 brd ff:ff:ff:ff:ff:ff
RX: bytes packets errors dropped overrun mcast

How does it compare to errors on the other interfaces? Is it significantly higher?

There are only errors on wrp (wrp1, wrp128, wrp192 ...). There are 0 errors/drops on all other interfaces.

Ok, gotcha. I recall seeing this in old R77.xx versions when sometimes sxl was enabled, but I would be shocked if thats the case any longer. Personally, I would attempt to change MTU size and test if possible, but if not, engage TAC and see what they say. If you run cpview, can you check the values you get there?

Does not match your current version but the symptoms seems to be similar

Thx.
RX errors increases indifferent if SecureXL is on or off.
MTU is default at 1500 on all interfaces.
Both cpview, ip link, ifconfig and clish show the same RX error result.

Thx. Well found.
The SK says "These errors are cosmetic" and it does match my version R81.10 (any take).

👍

That makes sense that it is just cosmetic, as interface errors are usually due to a physical media or a physical interface problem, neither of which even exist for wrp interfaces.

Correct, i see now that it applies to the version you are running 🙂
