Isilon 8 SNMP ipAddrTable

Hi, I'm experiencing a problem where Isilon 8.1.2 is returning a bad ipAddrTable from SNMP. There are 7 interfaces. Only a single row is returned from ipAddrTable, and it has the address as 0.0.0.0 and netmask as 0.54.120.0. An Isilon 7 configured similarly returns a complete set of rows with expected addresses and netmasks.

Does anyone know if this is a known issue, or perhaps related to some kind of misconfiguration?

Thanks,

Jim

Examples:

An Isilon 8 node (all cluster nodes return the same kind of bad info)

snmpwalk -v 2c -c <community> 10.200.60.133 ipAddrTable
IP-MIB::ipAdEntAddr.0.0.0.0 = IpAddress: 0.0.0.0
IP-MIB::ipAdEntIfIndex.0.0.0.0 = INTEGER: 2
IP-MIB::ipAdEntNetMask.0.0.0.0 = IpAddress: 0.54.120.0
IP-MIB::ipAdEntBcastAddr.0.0.0.0 = INTEGER: 0
IP-MIB::ipAdEntReasmMaxSize.0.0.0.0 = INTEGER: 65535

An Isilon 7 

snmpwalk -v 2c -c <comunity> 10.200.60.161 ipAddrTable
IP-MIB::ipAdEntAddr.10.20.60.161 = IpAddress: 10.20.60.161

Re: Isilon 8 SNMP ipAddrTable

Follow-up:
I found a couple of bsnmpd bugs that match this same condition: 
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195445
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=203264

Both are closed as fixed (seemingly in FreeBSD 10.2). Since the problem persists in FreeBSD 11.0-CURRENT, I logged a new one:
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=236408
