vismHdlcTxUnderflows
Module: CISCO-VISM-HDLC-MIB
OID (symbolic): CISCO-VISM-HDLC-MIB::vismHdlcTxUnderflows
OID (numeric): 1.3.6.1.4.1.351.110.5.5.6.1.1.9
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: This object describes the count of HDLC Tx underflow condition.
What is vismHdlcTxUnderflows?
This Counter32 counts the number of HDLC transmit underflow conditions on this channel. A transmit underflow means the outbound HDLC hardware ran out of data to send when it expected more, which an admin would treat as a sign of a local data-supply timing issue on the transmit path. For example, a rising vismHdlcTxUnderflows count alongside signaling delays might lead an admin to investigate whether the card is having trouble keeping the transmit buffer fed under load.
