• Following is an example to configure a VLAN ID for a port group on a specific virtual switch.
esxcfg-vswitch -v <VLAN ID> -p <port group name> <virtual switch name>
where:
VLAN ID ID of 0-4094. A value of 0 disables VLANs.
port group name Name of port group you have configured for virtual switch.
virtual switch name Name of virtual switch containing port group.
NOTE
For more information on using the esxcfg commands, refer to your VMware system documentation
or man pages.
• Following is an example to enable or disable Ethernet pause.
ethtool -A eth<X> [autoneg on|off] [rx on|off] [tx on|off]
where:
ethx Adapter position in server. For example, eth0 is the first Ethernet interface
found in the system, eth1 is the second, eth2 is the third, and so on.
autoneg Autonegotiate on or off
rx Receive on or off
tx Transmit on or off
Managing VMware driver configuration with ethtool
To enable or disable interrupt moderation, use the following command.
ethtool -C ethX adaptive-rx on|off
where:
ethx Adapter position in server. For example, eth0 is the first Ethernet interface
found in the system, eth1 is the second, eth2 is the third, and so on.
Configuring NetQueue
NetQueue improves receive-side networking performance on servers in 10 Gigabit Ethernet
virtualized environments. NetQueue provides multiple receive and transmit queues on the CNA,
which allows processing on multiple CPUs to improve network performance.
NOTE
MSI-X is enabled in the network driver by default, and must remain enabled for NetQueue to
function. Enabling NetQueue in VMware system also enables MSI-X in the system. Please make sure
that bnad_msix_disable=1 is not listed in VMware module parameters because that would disable
NetQueue.
