Description of problem: snmpwalk doesn't show any IPv6 related entry. Version-Release number of selected component (if applicable): net-snmp-5.1.2-11.EL4.6 How reproducible: every time Steps to Reproduce: 1. install net-snmp 2. configure /etc/snmp/snmpd.conf to be able to retrieve the whole tree 3. $ snmpwalk -c public -v 2c host | grep -i ipv6 Actual results: IPV6-MIB::ipv6Forwarding.0 = INTEGER: forwarding(1) IPV6-MIB::ipv6DefaultHopLimit.0 = INTEGER: 64 IPV6-MIB::ipv6Interfaces.0 = Gauge32: 5 IPV6-MIB::ipv6IfDescr.1 = STRING: lo IPV6-MIB::ipv6IfDescr.2 = STRING: eth0 IPV6-MIB::ipv6IfDescr.3 = STRING: eth1 IPV6-MIB::ipv6IfDescr.4 = STRING: eth2 IPV6-MIB::ipv6IfDescr.8 = STRING: tun6to4 IPV6-MIB::ipv6IfLowerLayer.1 = OID: SNMPv2-SMI::zeroDotZero IPV6-MIB::ipv6IfLowerLayer.2 = OID: SNMPv2-SMI::zeroDotZero IPV6-MIB::ipv6IfLowerLayer.3 = OID: SNMPv2-SMI::zeroDotZero IPV6-MIB::ipv6IfLowerLayer.4 = OID: SNMPv2-SMI::zeroDotZero IPV6-MIB::ipv6IfLowerLayer.8 = OID: SNMPv2-SMI::zeroDotZero IPV6-MIB::ipv6IfEffectiveMtu.1 = Gauge32: 16436 octets IPV6-MIB::ipv6IfEffectiveMtu.2 = Gauge32: 1500 octets IPV6-MIB::ipv6IfEffectiveMtu.3 = Gauge32: 1500 octets IPV6-MIB::ipv6IfEffectiveMtu.4 = Gauge32: 1500 octets IPV6-MIB::ipv6IfEffectiveMtu.8 = Gauge32: 1480 octets IPV6-MIB::ipv6IfPhysicalAddress.1 = STRING: IPV6-MIB::ipv6IfPhysicalAddress.2 = STRING: 0:1:2:**:**:** IPV6-MIB::ipv6IfPhysicalAddress.3 = STRING: 0:0:cb:**:**:** IPV6-MIB::ipv6IfPhysicalAddress.4 = STRING: 0:0:e8:**:**:** IPV6-MIB::ipv6IfPhysicalAddress.8 = STRING: 54:99:56:**:**:** IPV6-MIB::ipv6IfAdminStatus.1 = INTEGER: up(1) IPV6-MIB::ipv6IfAdminStatus.2 = INTEGER: up(1) IPV6-MIB::ipv6IfAdminStatus.3 = INTEGER: down(2) IPV6-MIB::ipv6IfAdminStatus.4 = INTEGER: up(1) IPV6-MIB::ipv6IfAdminStatus.8 = INTEGER: up(1) IPV6-MIB::ipv6IfOperStatus.1 = INTEGER: up(1) IPV6-MIB::ipv6IfOperStatus.2 = INTEGER: up(1) IPV6-MIB::ipv6IfOperStatus.3 = INTEGER: up(1) IPV6-MIB::ipv6IfOperStatus.4 = INTEGER: up(1) IPV6-MIB::ipv6IfOperStatus.8 = INTEGER: up(1) Expected results: ipv6IfTable entries containing the IPv6 addresses of the interface Also missing: IPv6-TCP and IPv6-UDP Additional info: net-snmp-5.3-4.2 of FC5 does the job (for the interfaces, not for TCP/UDP, will file an additional bug), but uses also the new MIB layout where IPv4 and IPv6 is combined in IP-MIB
ipv6AddrTable OID is not implemented in net-snmp-5.1.2. It is not possible to port it back from net-snmp-5.2.1, because it uses lot of features of the newer version. It could be possible to reimplement the OID from scratch, but it would take quite lot of effort. If you want this OID implemented, please contact your Red Hat support :). You can use RHEL 5, where the ipv6AddrTable is properly implemented.
