physicalAdapterIpv4TCPSegmentationOffLoadEnable
Module: INTEL-LAN-ADAPTERS-MIB-3
OID (symbolic): INTEL-LAN-ADAPTERS-MIB-3::physicalAdapterIpv4TCPSegmentationOffLoadEnable
OID (numeric): 1.3.6.1.4.1.343.2.7.2.2.2.2.1.6
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: When enabled, TCP Segmentation is performed in hardware.
What is physicalAdapterIpv4TCPSegmentationOffLoadEnable?
Indicates whether TCP Segmentation Offload (TSO) is enabled (1) or disabled (0) on this physical adapter, letting the NIC split large outbound TCP payloads into MTU-sized frames in hardware instead of the OS doing it. Enabling TSO typically reduces CPU usage for high-throughput transmit workloads.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.343.2.7.2.2.2.2.1.6 snmpwalk -v2c -c public <target> INTEL-LAN-ADAPTERS-MIB-3::physicalAdapterIpv4TCPSegmentationOffLoadEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.343.2.7.2.2.2.2.1.6.1 snmpget -v2c -c public <target> INTEL-LAN-ADAPTERS-MIB-3::physicalAdapterIpv4TCPSegmentationOffLoadEnable.1
