asioSapOprPortQueueUpperThreshold

Module: CXAsyncIo-MIB

OID (symbolic): CXAsyncIo-MIB::asioSapOprPortQueueUpperThreshold

OID (numeric): 1.3.6.1.4.1.495.2.1.6.44.1.1.9

Node type: OBJECT-TYPE

Type: INTEGER

Access: read-write

Description: Defines the queue length, in number of buffers, after which the Async driver starts flow controlling the upper layer.

After the queue has reached this length, the Async driver will queue more data requests on the transmit queue up to the length specified in object asySapOprPortMaxQueueLength. Data is discarded above that length.

The value for this object should always be less than the value of object asySapOprPortMaxQueueLength

Range of Values: 1 - 100

Default Value: 45

Configuration Changed: Operative only

What is asioSapOprPortQueueUpperThreshold?

Sets the transmit queue depth in buffers (1-100, default 45) at which the driver starts flow-controlling the upper layer for this port; it should always be set below asioSapOprPortMaxQueueLength so flow control kicks in before data actually starts getting dropped.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.44.1.1.9
snmpwalk -v2c -c public <target> CXAsyncIo-MIB::asioSapOprPortQueueUpperThreshold

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.4.1.495.2.1.6.44.1.1.9.1
snmpget -v2c -c public <target> CXAsyncIo-MIB::asioSapOprPortQueueUpperThreshold.1

Set instance 1 (SNMPv2c):

snmpset -v2c -c private <target> 1.3.6.1.4.1.495.2.1.6.44.1.1.9.1 i <value>
