bearerLcn
Module: CISCO-VISM-ATM-TRUNK-MIB
OID (symbolic): CISCO-VISM-ATM-TRUNK-MIB::bearerLcn
OID (numeric): 1.3.6.1.4.1.351.110.5.5.9.1.1.3
Node type: OBJECT-TYPE
Type: Integer32
Access: read-only
Description: This attribute defines the PVC or LCN(Logical Channel Number) number to which this bearer connection is associated with. This refers to the same value as in vismCnfChanNum in vismChanCnfGrp table. This is define in CISCO-VISM-CONN-MIB MIB.
What is bearerLcn?
This Integer32 object identifies the PVC or Logical Channel Number that a bearer connection is associated with, matching vismCnfChanNum in the vismChanCnfGrp table of CISCO-VISM-CONN-MIB. This ties a specific voice bearer connection to the underlying ATM virtual circuit carrying it, letting an admin trace call-quality issues down to the PVC transporting them. When multiple bearer connections show packet loss simultaneously, an engineer would check whether they all share the same LCN, pointing to a shared PVC problem rather than isolated call issues.
