ErrIfindex

[sdide]

hey all,

I have a server department with a vmware guest with some "performance issues." that they apparently cannot eloborate on. They asked me to see if there were any apparent network issues.

Ok, on a 5700-40XG-2QSFP+ (R2311P04.) 

If i do a

# display ethernet statistics slot 1

my "ErrIfindex" counter rises..

My question is. What is "ErrIfindex" ?

The manual says:

"ETH receive error statistics

 Statistics about the error Ethernet packets in the outbound direction on the
Ethernet interface module. Errors might be included in packets or occur during
the receiving process. The items include:"

...

ErrIfindex—Number of packets that include incorrect interface indexes.

...

"

but what what is an "incorrent interface index" regarding a packet?

Regards
