Subject: [c-nsp] Counters for null0?
Hi, is there any way to see how much traffic is going to null0
interface?
I configured several routes to be forwarded to null0 and I would like to
have some info about how much traffic is going there.
If the IOS doesn't

Yes, but I just can see the output counters growing up. Quite strange
since null0 is not generating traffic and it has configured no ip
unreachables.

I just configure a router here to use it but it is quite strange because
I can see correct traffic routed to null, and I didn't expect to see

There are scenarios (nat, acl drops, etc.) where the dst in the netflow
will show null.
For a transit packet that is forwarded out will not (should not) show Null.

yes, output counters are those that have a meaning. it's traffic
that's
I think it will also show Null when it is forwarded but goes through a
permit ACL with log keyword

Yes, this is a NAT scenario, maybe that is the reason.
So far the router is working ok, and the service is ok too.
So null value must be related with NAT or something similar.

Most Cisco routers (the main exceptions being 6500/7600/4500 switches,
with their well-known NetFlow caveats regarding dropped traffic) show
the destination ifindex as 0 when the
Yes it is being translated by NAT for sure, I am 110% sure about that.

If a given IOS version does that, it's a bug.
ifout = NULL usually means traffic dropped due to ACL or no route.
