how to verify status of TCP Segmentation Offloading

  • 772

we do the following on linux rhel machines

ethtool -K ifcfg-478476 tso off

now lets say that we want to verify the settings

how to do the check with ethtool or other cli?

we try

ethtool -k ifcfg-478476 | grep -i tso

but we not get status

any idea ?

note - ifcfg-478476 is the eth link

redhat networking dmesg linux-networking ethtool

    In the output of ethtool -k, it is called tcp-segmentation-offload, not tso. The output is like this:

    tcp-segmentation-offload: on
    tx-tcp-segmentation: on
    tx-tcp-ecn-segmentation: on
    tx-tcp6-segmentation: on
