Managing VMware driver configuration with cfg
•
Following is an example of using the esxcfg-module command to disable message signaled
interrupts (MSI-X).
esxcfg-module -s ”bnad_msix_disable=1” bna
where:
bnad_msix_disableBrocade network adapter message signaled interrupts
1
Disables MSI-X and enables INTx mode instead.
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 by default. If
enabling NetQueue, make sure that bnad_msix_disable=1 is not listed in VMware module
parameters because that would disable NetQueue.
•
Display current driver configuration settings using the following command:
esxcfg-module -g bna
•
Following is an example of using the esxcfg command to set the Jumbo Packet (MTU) size.
First, set the MTU size on a virtual switch using the following command.
esxcfg-vswitch -m
where:
MTU size
MTU size (1500-9000 kb)
vSwitch ID
Virtual switch identification, such as vSwitch0
Display a list of virtual switches on the host system and their configurations using the following
command.
esxcfg-vswitch -l
Next, create VMkernal interface with the MTU setting.
esxcfg-vmknic -a “VM Kernel” -i
where:
VM Kernel
VMkernal name.
