cwdsiWnmDropUmdTxMsgCount
Module: CISCO-WDS-INFO-MIB
OID (symbolic): CISCO-WDS-INFO-MIB::cwdsiWnmDropUmdTxMsgCount
OID (numeric): 1.3.6.1.4.1.9.9.509.1.4.1.1.11
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object specifies the number of dropped messages by WDS because of the Unacknowledged Message Descriptor (UMD) allocation problem before sending the messages to Wireless Network Manger. Discontinuities in the value of this counter can occur at re-initialization of the WDS, and at other times as indicated by the value of cwdsiWnmDiscontinuityTime.
What is cwdsiWnmDropUmdTxMsgCount?
This read-only Counter32 counts the number of outbound messages dropped by the WDS due to an Unacknowledged Message Descriptor (UMD) allocation problem before they could be sent to the Wireless Network Manager. An admin monitors this as a resource-exhaustion indicator in the WDS's outbound messaging path. For example, a rising cwdsiWnmDropUmdTxMsgCount during heavy AP/client churn would suggest the WDS is running short of UMD resources for outbound WNM traffic.
