What Is HPN-ICF-L2VPN-PWE3-MIB?

HPN-ICF-L2VPN-PWE3-MIB is a Hewlett-Packard Networking MIB (the hpnicf* prefix denotes HP Networking's ICF/Comware-derived MIB family shared with H3C, under HPN-ICF-OID-MIB's hpnicfCommon arc) that manages PWE3 (Pseudo Wire Emulation Edge-to-Edge) pseudowire configuration for L2VPN services on HP Comware-based MPLS devices. Its central hpnicfPwVcTable, indexed by hpnicfPwVcIndex, defines each pseudowire's hpnicfPwVcID (the outgoing VC-FEC ID), hpnicfPwVcType (an extensive HpnicfL2VpnVcEncapsType enumeration covering Frame Relay, ATM AAL5/cell-transport modes, Ethernet/Ethernet-tagged, HDLC, PPP, CESoPSN/TDMoIP TDM-over-packet modes, and more), the hpnicfPwVcPeerAddr and negotiated MTU, inbound/outbound MPLS labels (hpnicfPwVcInboundLabel/OutboundLabel), the bound local interface (hpnicfPwVcIfIndex), and both hpnicfPwVcAcStatus (attachment-circuit up/down) and hpnicfPwVcStatus (overall pseudowire status), with hpnicfPwVcRowStatus controlling lifecycle and a global hpnicfPwVcTrapOpen toggle for pseudowire-state notifications. Monitoring this table reveals whether a pseudowire's attachment circuit and remote signaling are both up — a common failure mode is an AC that's up locally while the PW itself remains down due to label or peer-reachability issues on the MPLS core. It depends on HPN-ICF-OID-MIB for its OID root and on SNMPv2-SMI/TC for base types, and it is deployed on HP/H3C Comware-based MPLS routers and switches providing L2VPN pseudowire services; network teams can pull the HPN-ICF-L2VPN-PWE3-MIB MIB Browser output to confirm exact object names before scripting PW-health checks.

IPNetwork Monitor allows you to monitor SNMP objects defined in HPN-ICF-L2VPN-PWE3-MIB. 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

HP/H3C Comware-based MPLS routers and switches (HP Networking ICF platform)

Monitoring Examples

An operator polls hpnicfPwVcTable for a given hpnicfPwVcIndex to check hpnicfPwVcAcStatus and hpnicfPwVcStatus together; an attachment circuit reporting up(2) while hpnicfPwVcStatus remains down would indicate the MPLS core signaling or label exchange for that pseudowire has failed even though the local access-side circuit is healthy.

What Can Be Monitored

pseudowire VC configuration and encapsulation type
peer address and negotiated MTU
inbound/outbound MPLS label assignment
attachment-circuit status
overall pseudowire operational status
pseudowire trap/notification enable state
