Network driver parameters A VMware Table 39 describes the instance-specific network configuration parameters available for VMware hosts. You can list all module parameters that you can configure for the network driver using the following command. vmkload_mod -s bna TABLE 39 Network driver configuration parameters Function Default Value Possible Values Method to Configure Notes Jumbo Packet Size 1500 1500-9000 esxcfg-vswitch command • Sets MTU size. • Size must not be greater than size set on FCoE switch. • You must enable the MTU size for each vswitch or VMkernal interface.

However, the NetQueue feature of VMware must be enabled in the VMware system to enable MSI-X in the system. • Driver will attempt to enable, but use INTx in case MSI-X is not supported or NetQueue is not enabled. Interrupt Moderation On On (Set for receive Off interrupts) ethtool -C command Reduces context switching and CPU utilization. When enabled, the hardware will not generate an interrupt immediately after it receives a packet, but waits for more packets or a time-out to expire NetQueue Enabled Enable Disable VM Client interface Enables NetQueue for improving receive-side networking performance on servers with multiple CPUs.
