Cisco VPN 3000 returns a non unique Port name when doing
snmpwalk –c snmp_ro_community 192.168.0.1 ifTable

Example:
IF-MIB::ifDescr.1 = STRING: DEC 21143A PCI Fast Ethernet
IF-MIB::ifDescr.2 = STRING: DEC 21143A PCI Fast Ethernet

Mac addresses are unique. IFname is unique in IFMIB.

    the product becomes obsolete (unsupported) on August 31, 2012. closing this ticket because it's unlikely we'll find someone with a running device to test against.

    Still, I don't really see what the problem is. Yes, Cisco VPN3000 returns non-unique ifDescr instances when queried with snmpwalk. There's nothing we can do about /that/, or at least I don't think it's a good idea to try fixing the device behhavior by modifying vendor firmware with a hex editor.

    Our SNMP::Info class supporting this device (SNMP::Info::Altiga) deals with this issue, the interfaces() method returns unique names. I'm sure about that because it's the first SNMP::Info class that I wrote to get the VPN3030 in our network into Netdisco. It's not my cleanest code ever but it worked :-)

    The link to the original Netdisco ticket doesn't work anymore, but I'm pretty sure this ticket is obsolete.
