CADANT-MPLS-MIB

Description: Manages MPLS label switching configuration and forwarding on ARRIS/Cadant CMTS platforms for carrier Ethernet services.

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.

CADANT-MPLS-MIB is ARRIS's (formerly Cadant's) proprietary MIB for managing MPLS label switching and LDP-based label distribution on Cadant CMTS (Cable Modem Termination System) platforms, used to carry MPLS-based carrier Ethernet/backhaul services over cable infrastructure. It exposes LDP protocol timers (hello/targeted-hello/keepalive hold timers), virtual-circuit description objects, and an LDP neighbor table capturing peer address, authentication password, targeted-peer flag, and row status for each LDP adjacency. Its monitoring value is centered on MPLS control-plane software health: whether LDP neighbor sessions are correctly established and authenticated, and whether hold-timer settings are appropriate to avoid premature session teardown, which is a control-plane status indicator on the CMTS rather than a physical hardware sensor. It builds conceptually on standard MPLS/LDP concepts (paralleling MPLS-LDP-STD-MIB) while implementing Cadant/ARRIS-specific object naming and a proprietary neighbor table. It is typically deployed on ARRIS/Cadant CMTS platforms in cable operator networks that use MPLS to backhaul or aggregate Carrier Ethernet business services over the DOCSIS access network. Engineers can download the CADANT-MPLS-MIB file directly to load it into their MIB browser.

An operator would poll cadMplsLdpNeighborTable/cadMplsLdpNeighborEntry to check cadMplsLdpNeighborIpAddress and cadMplsLdpNeighborRowStatus for each configured LDP peer, confirming the session is active and not stuck in a notInService state. cadMplsLdpNeighborTargetedPeer distinguishes directly-connected from targeted (remote) LDP sessions, which matters for diagnosing why a particular peer isn't forming an adjacency. cadMplsLdpHelloHoldTimer, cadMplsLdpTargetedHelloHoldTimer, and cadMplsLdpKeepAliveHoldTimer would be reviewed together when an LDP session is flapping, to rule out overly aggressive timer settings, while cadMplsLdpNeighborPassword confirms authentication is configured consistently between peers.
