Guidelines for setting the maximum transmission unit (MTU) for LLT interconnects in Flexible Storage Sharing (FSS) environments
Review the following guidelines for setting the MTU for LLT interconnects in FSS environments:
Set the maximum transmission unit (MTU) to the highest value (typically 9000) supported by the NICs when LLT (both high priority and low priority links) is configured over Ethernet or UDP. Ensure that the switch is also set to 9000 MTU.
Note:
MTU setting is not required for LLT over RDMA configurations.
For virtual NICs, all the components - the virtual NIC, the corresponding physical NIC, and the virtual switch - must be set to 9000 MTU.
If a higher MTU cannot be configured on the public link (because of restrictions on other components such as a public switch), do not configure the public link in LLT. LLT uses the lowest of the MTU that is configured among all high priority and low priority links.
