Module: CISCO-VISM-CONN-STAT-MIB
OID (symbolic): CISCO-VISM-CONN-STAT-MIB::vismChanAal5OversizedSdusRcvdPdus
OID (numeric): 1.3.6.1.4.1.351.110.5.5.3.3.1.1.22
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object counts the number AAL5 PDUs dropped due to the SDU(Service Data Unit) size bigger than the configured value. This is applicable for AAL5 PVCs only.
What is vismChanAal5OversizedSdusRcvdPdus?
This Counter32 counts AAL5 PDUs dropped because the received SDU size exceeded the configured maximum, applicable only to AAL5 PVCs. A rising count here suggests the far end is sending payloads larger than this channel's configured SDU size limit, which the local side rejects rather than accepting. An engineer diagnosing dropped AAL5 traffic on a channel would check whether oversized SDUs are the cause, prompting a review of the configured maximum size against what the remote end is actually sending.
