Description: Manages IPv6 addressing, neighbor discovery, and interface configuration on Cisco Small Business devices.

Start monitoring vendor-neutral, standards-based MIB, any SNMPv3-capable network device (SNMP engine identity/boot/clock status) with a free 30-day trial of IPNetwork Monitor. Import MIBs, browse SNMP OIDs, create custom SNMP monitors, configure alerts, and monitor any SNMP-enabled network device from a single console.

What Is CISCOSB-IPv6?

CISCOSB-IPv6 is a Cisco Small Business private MIB that manages IPv6 addressing and per-interface IPv6 protocol behavior, including neighbor discovery parameters, autoconfiguration, and MLD version. It falls in the network-configuration category, exposing IP address tables with prefix length and address type alongside a per-interface IPv6 configuration table controlling duplicate-address-detection attempts, ICMP unreachable sending, link MTU, and retransmit timers. Its monitoring role is primarily software/protocol-configuration status rather than hardware health, letting an operator verify that IPv6 autoconfiguration and neighbor discovery are behaving as expected on each interface and catch misconfigured MTU or DAD settings that could cause connectivity issues. It builds on standard IPv6 concepts akin to IP-MIB/IPV6-MIB but is implemented as a CISCOSB private-tree variant rather than the IETF standard. It is used on small-business switches and routers being migrated to or run in dual-stack/IPv6 environments, and network admins can download the CISCOSB-IPv6 MIB to add it to their monitoring toolset.

IPNetwork Monitor allows you to monitor SNMP objects defined in CISCOSB-IPv6. Use the built-in SNMP Monitoring Browser to explore available variables, view their current values and descriptions, and select the objects you want to monitor. You can then create SNMP monitors, configure thresholds, and receive alerts when monitored values change.

Supported Devices

  • Cisco Small Business switches and routers

Monitoring Examples

An administrator would poll rlipv6InterfaceTable/rlipv6InterfaceEntry to check rlipv6InterfaceAutoconfigEnable and rlipv6InterfaceNdDadAttemps per interface, confirming that duplicate address detection is configured with a sane retry count rather than disabled. Reviewing rlIpAddressTable's rlIpAddressType and rlIpAddressPrefixLength verifies that an interface has the expected IPv6 prefix assigned. An interface unexpectedly showing rlipv6InterfaceLinkMTU far below the network's standard MTU would point to a fragmentation-related connectivity problem worth investigating.

What Can Be Monitored

  • IPv6 address and prefix length
  • IPv6 autoconfiguration status
  • neighbor discovery DAD attempts
  • link MTU
  • MLD version
  • retransmit timer
