BGP AS collect issue

in NetFlow Analyzer  •  All Categories  •  04 Jun, 09:09 PM

as the picture show , AS4319 was highlighted . but it actully was 135391, if you use as-notation format to express ,  it should be 2:4319,as i know , BGP AS has extended from 2 Byte to 4 Byte, it looks like NTA did not recognize the pre 2 Byte of BGP AS 

i test it on analyzer v9 and v12 , it has the same result .

Hi ,

Thank you for writing to us. We get the AS number information using the information exported by the device over the NetFlow Packets. As the information is sent from the Device, we do not have the option the change the format of AS number.

Thanks & Regards,

do you know how many bits has design for AS information in Netflow packets ? do you think it is possible that current Netflow  packet can not include a 4 Bytes BGP AS number ?
