Module: Nortel-Magellan-Passport-Frf5EpMIB

OID (symbolic): Nortel-Magellan-Passport-Frf5EpMIB::mcsMgrFrf5EpGEpDlciABitReasonToIf

OID (numeric): 1.3.6.1.4.1.562.2.4.1.122.14.3.4.10.1.2

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-only

Description: This attribute indicates the reason for the latest inactive A-bit status sent to the ATM VCC. The value is notApplicable when the aBitStatusToNetwork is active. The value is remoteUserSignaled if the FrAtm originating the A-Bit status has detected that the virtual circuit is down at the remote network through the LMI protocol. The FrAtm must be running network site LMI protocol for this A-Bit status reason to be sent. The value is localLmiError if the LMI protocol is down at this Ep. The value is remoteLmiError if the LMI protocol is down at the FrAtm originating this A-Bit status reason. The value is localLinkDown if the physical interface is disabled at this Ep. The value is pvcDown if no A-Bit status has been sent to this Ep (i.e., no A-Bit status has been relayed from the FrAtm). The value is remoteLinkDown if the physical interface is disabled at the FrAtm originating this A-Bit status reason.

What is mcsMgrFrf5EpGEpDlciABitReasonToIf?

Reports why this DLCI's A-bit status sent toward the ATM VCC was last marked inactive, one of notApplicable(0, the default when active), remoteUserSignaled(1), localLmiError(2), remoteLmiError(3), localLinkDown(4), remoteLinkDown(5), or pvcDown(6). This is the field to check to pin down exactly why this virtual circuit is being reported down toward the network side.
