hm2ConnTrackValidateCheckSum
Module: HM2-FW-MIB
OID (symbolic): HM2-FW-MIB::hm2ConnTrackValidateCheckSum
OID (numeric): 1.3.6.1.4.1.248.11.79.1.1.6
Node type: OBJECT-TYPE
Type: TruthValue
Access: read-write
Description: This value describes, whether the Firewall connection tracking in the Linux kernel shall validate the protocol checksums. Disable this validation (false) improves routing throughput.
What is hm2ConnTrackValidateCheckSum?
This read-write boolean controls whether the Linux kernel's connection tracking validates protocol checksums on packets passing through the firewall; setting it to false skips that validation to improve routing throughput. An admin on a high-throughput link experiencing CPU pressure might disable this, trading a small amount of packet-integrity checking for speed.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.6.1.4.1.248.11.79.1.1.6 snmpwalk -v2c -c public <target> HM2-FW-MIB::hm2ConnTrackValidateCheckSum
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.6.1.4.1.248.11.79.1.1.6.1 snmpget -v2c -c public <target> HM2-FW-MIB::hm2ConnTrackValidateCheckSum.1
Set instance 1 (SNMPv2c):
snmpset -v2c -c private <target> 1.3.6.1.4.1.248.11.79.1.1.6.1 s <value>
