cpqiScsiPortalMaxRecvDataSegLength
Module: CPQISCSI-MIB
OID (symbolic): CPQISCSI-MIB::cpqiScsiPortalMaxRecvDataSegLength
OID (numeric): 1.3.6.1.4.1.232.169.2.3.1.1.8
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-write
Description: The maximum PDU length this portal can receive. This may be constrained by hardware characteristics and individual implementations may chose not to allow this object to be changed.
What is cpqiScsiPortalMaxRecvDataSegLength?
This read-write INTEGER (512-16777215) sets the maximum PDU length, in bytes, that this portal can receive, which may be constrained by the underlying hardware. An admin tunes this to optimize iSCSI performance, since larger segment sizes can reduce protocol overhead on high-throughput links, though some implementations don't allow changing it. For example, increasing this value on a high-bandwidth link could improve large-block storage I/O throughput if the hardware supports it.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.232.169.2.3.1.1.8 snmpwalk -v2c -c public <target> CPQISCSI-MIB::cpqiScsiPortalMaxRecvDataSegLength
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.232.169.2.3.1.1.8.1 snmpget -v2c -c public <target> CPQISCSI-MIB::cpqiScsiPortalMaxRecvDataSegLength.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.232.169.2.3.1.1.8.1 i <value>
