Unkown interface names with Enterasys SSR-8600

Hi,

I am using Netflow with Enterasys SSR-8000 and SSR-8600.

I have configured Netflow correctly with SNMP-Communities and all known interfaces of the routers are shown.

Beside the "normal" port-names I get every day new ifindexXXX-port-names which can not be resolved.

E.g. a router has 81 physikal and logical interfaces, but netflow reports ifindex82 and up to ifindex255. Every day I get new ifindex-entries between ifindex82 and ifindex255.

I tried to read the mib with the troubleshooting-tool SnmpWalk.bat and this tool only reports ifindex-number upto 81, which are the only know ports.

Is this a Netflow-Analyzer bug or a Enterasys bug or is there any other reason for this unknown ifindex-entries?

Regards,
Manuel
