Module: CISCO-VISM-CONN-STAT-MIB
OID (symbolic): CISCO-VISM-CONN-STAT-MIB::vismChanAal2InvOsfCells
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.3.1.1.14
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object keeps track of the number AAL2 cells dropped due to invalid OSF (OffSet Field) in the egress direction.
What is vismChanAal2InvOsfCells?
This Counter32 tracks the number of AAL2 cells dropped due to an invalid OSF (OffSet Field) in the egress direction. An invalid offset field means the cell's internal structure couldn't be correctly parsed for CPS packet boundaries, which can result in lost voice payload segments on egress. An engineer chasing a specific pattern of choppy audio on egress traffic for a channel would check this counter to see if OSF field corruption is contributing.
