AS 23456

[Alexander Seitz]

Hi all,

Since I upgraded as-stats to the latest version, and also going to 15.1 Version on our Sup2T's I see a lot of traffic for AS 23456
AS 23456 is used for compatibility with 4-byte ASN's.
Now my question is: can't as-stats handle 4-byte ASN's or the cisco router ?

And ideas ?

Best regards !

Hello Alex,

I'm not sure if you already got your answer. In the past a co-worker setup it as-stats and I also wondered about this AS. I found out at some point he was using Sflow 5 which couldn't handle that.
When we've upgraded later to IPFIX and also updated the asinfo file, we got all stats as expected.

Cheers
