NimbostratusHardware platform and TSO (TCP Segmentation Offoload) support
Is there any documentation that shows what hardware platforms support TCP Sementation Offload?
Specifically trying to see if the 2000s supported this.
giltjrThat's the only thing I have found. We migrated from 2000s to VE and have started experincing a problem dealing with TSO and we are trying to see if we would have had the issue on 2000s.
While I'm also not sure about the hardware, I did find this about the feature:
K15609: Overview of TCP Segmentation Offload and Large Receive Offload
In addition, this is about VE and about 2/3 of the way down is the TSO info: https://techdocs.f5.com/kb/en-us/products/big-ip_ltm/manuals/product/bigip-ve-setup-vmware-esxi-11-6-0/1.html
About TCP Segmentation Offloading support
If you want to disable support for TCP Segmentation Offloading (TSO), you must submit a tmsh command, because the TSO feature is enabled by default. Note that enabling TSO support also enables support for large receive offload (LRO) and Jumbo Frames.
Configuring a hypervisor for TSO support
You must have the Admin user role to enable or disable TSO support for a hypervisor.
Using the tmsh command sys db, you can turn TSO support on, off, or check to see whether support is currently enabled.- giltjr
I understand that, but TSO is not actually use unless the network card supports it. I'm trying to figure out if the network cards in the 2000s supported TSO.
