APPIAN-TRUNK-FR-MIB

Description: Appian Communications Frame Relay trunk configuration and PVC status management.

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.

This is an Appian Communications vendor MIB for managing Frame Relay trunk interfaces on Appian's access/aggregation platforms, covering trunk-level LMI (Local Management Interface) protocol configuration and PVC status. It exposes configuration data for each Frame Relay trunk — LMI protocol type, polling mode, and the standard Frame Relay timers/counters (T391, T392, N391, N392, N393) — alongside trunk sharing settings. It is primarily used for monitoring the software/protocol-level health of Frame Relay trunks, since LMI protocol mismatches or incorrect timer values are a classic cause of a Frame Relay trunk failing to establish or repeatedly flapping, and this MIB lets an administrator confirm those parameters match the carrier/peer configuration. It parallels concepts from the standard Frame Relay DTE/DCE interface MIB (RFC 2115) though implemented as an Appian-specific enterprise MIB. It is typically deployed on Appian Communications access platforms in service-provider or enterprise WAN environments using Frame Relay trunking to aggregate multiple PVCs. Engineers can download the APPIAN-TRUNK-FR-MIB file directly to load it into their MIB browser.

An administrator would poll acFrTrunkTable/acFrTrunkEntry indexed by acFrTrunkIndex to check acFrTrunkLmiProtocol and acFrTrunkLmiPollingMode, confirming the LMI type matches what the carrier expects; if the trunk is failing to come up, comparing acFrTrunkT391/T392 and acFrTrunkN391/N392/N393 timer values against the peer's configuration would reveal a timer mismatch causing repeated LMI status-inquiry failures, and acFrTrunkShared indicates whether the trunk's bandwidth is being shared across multiple logical circuits.
