Module: CISCO-VISM-CONN-STAT-MIB
OID (symbolic): CISCO-VISM-CONN-STAT-MIB::vismChanAal5Crc32ErrorPdus
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.3.1.1.24
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object counts the number of AAL5 PDUs dropped in the egress direction due to CRC-32 errors detected by the SAR(Segmentation and Reassembly).
What is vismChanAal5Crc32ErrorPdus?
This Counter32 counts AAL5 PDUs dropped in the egress direction due to CRC-32 errors detected by the SAR (Segmentation and Reassembly) function. CRC-32 failures on AAL5 PDUs indicate cell-level corruption affecting the reassembled frame's integrity, which for a signaling PVC could mean lost call-control messages. An engineer chasing dropped signaling messages on an AAL5 CCS PVC would check this counter to see if reassembly-stage CRC errors are the source of the loss.
