Hi, I am playing with one of http://www.netoptics.com/products/ilink-agg-xstream/ilink-agg-xstream these devices and Zenoss 4.2.3 is not detecting the interfaces through the standard modeler, zenoss.snmp.InterfaceMap.
Further investigation and an snmpwalk of the device shows that the interfaces are not in the usual place in the MIB.

How can I work round this? I have no idea how to write modelers :|

So where DO these things keep interface information??Â Zenoss tries two standard MIBs for interface info:

| | # Interface related tables likely to be used in all subclasses. |
| | baseSnmpGetTableMaps = ( |
| Â Â Â | GetTableMap('iftable', '.1.3.6.1.2.1.2.2.1', |
| Â Â Â Â Â Â Â Â Â Â Â | {'.1': 'ifindex', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.2': 'id', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.3': 'type', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.4': 'mtu', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.5': 'speed', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.6': 'macaddress', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.7': 'adminStatus', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.8': 'operStatus'} |
| Â Â Â | ), |
| Â Â Â | # ipAddrTable is the better way to get IP addresses |
| Â Â Â | GetTableMap('ipAddrTable', '.1.3.6.1.2.1.4.20.1', |
| Â Â Â Â Â Â Â Â Â Â Â | {'.1': 'ipAddress', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.2': 'ifindex', |
| Â Â Â Â Â Â Â Â Â Â Â Â | '.3': 'netmask'} |
| Â Â Â | ), |
Â (from $ZENHOME/Products/DataCollector/plugins/zenoss/snmp/InterfaceMap.py).

If your device doesn't use either of these standards then you are going to have to get into your own modeler if you really need to do this.Â How many of these beasties do you have?Â Is it worth writing your own modeler - or getting someone else to do it for you :) ?

Cheers,
Jane

Hi Jane,
Thanks for your reply :)
NetOptics hide them here in 1.3.6.1.4.1.23022.100.3 and .4, so totally non-standard. I've realised that a new modeler would need to be written in this instance and am working with NetOptics direct to see if they can do that for me + write a zenpack.
I'll report back in to this thread if/when I get this working.

Thanks
