iscsiNodeMaxOutstandingR2T
Module: ISCSI-MIB
OID (symbolic): ISCSI-MIB::iscsiNodeMaxOutstandingR2T
OID (numeric): 1.3.6.1.2.1.142.1.5.1.1.8
Node type: OBJECT-TYPE
Type: Unsigned32
Access: read-write
Description: Maximum number of outstanding requests-to-transmit (R2Ts) allowed per iSCSI task.
What is iscsiNodeMaxOutstandingR2T?
Caps how many Ready-to-Transfer requests can be outstanding per iSCSI task on this node (default 1); raising it can improve write throughput on high-latency links at the cost of more buffering.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.2.1.142.1.5.1.1.8 snmpwalk -v2c -c public <target> ISCSI-MIB::iscsiNodeMaxOutstandingR2T
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.2.1.142.1.5.1.1.8.1 snmpget -v2c -c public <target> ISCSI-MIB::iscsiNodeMaxOutstandingR2T.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.2.1.142.1.5.1.1.8.1 i <value>
SNMPv3 example:
snmpget -v3 -l authPriv -u snmpv3-user -a SHA -A "AuthPassword1" -x AES -X "PrivPassword1" <target> iscsiNodeMaxOutstandingR2T.1
