physicalAdapterTcpRxChecksumOffLoadEnable
Module: INTEL-LAN-ADAPTERS-MIB-2
OID (symbolic): INTEL-LAN-ADAPTERS-MIB-2::physicalAdapterTcpRxChecksumOffLoadEnable
OID (numeric): 1.3.6.1.4.1.343.2.7.2.2.2.2.1.1
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: When enabled, TCP for 'receive' checksums are performed in hardware.
What is physicalAdapterTcpRxChecksumOffLoadEnable?
Indicates whether this adapter is offloading TCP receive-checksum calculation to hardware rather than the host CPU; disabling it shifts that work back onto the CPU, useful to know when chasing a CPU-utilization spike.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.343.2.7.2.2.2.2.1.1 snmpwalk -v2c -c public <target> INTEL-LAN-ADAPTERS-MIB-2::physicalAdapterTcpRxChecksumOffLoadEnable
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.343.2.7.2.2.2.2.1.1.1 snmpget -v2c -c public <target> INTEL-LAN-ADAPTERS-MIB-2::physicalAdapterTcpRxChecksumOffLoadEnable.1
