vif - create and destroy virtual interfaces
vif create [ vif_name ] interface_name ...
vif destroy vif_name
vif stat vif_name [ interval ]
The vif command creates and eliminates virtual interfaces. It also displays statistics for a specified virtual interface.
The vif create command creates a virtual interface. The name of the virtual interface to be created is specified as vifn, where n is a number. Make sure that the specified virtual interface name is not already in use. Use the ifconfig command to check and see what virtual interface names are being used.
You can specify up to four Ethernet interfaces in the command. The interfaces do not have to be on the same network card. However, some Ethernet switches or routers require that all Ethernet interfaces forming a virtual interface be either half-duplex or full-duplex. Check the documentation that comes with your Ethernet switch or router to see whether you need to configure the filer Ethernet interfaces to be half-duplex or full-duplex.
The vif destroy command eliminates an existing virtual interface. You must configure the virtual interface down using the ifconfig command before entering the vif destroy command.
The vif stat command displays the number of packets received and transmitted on each Ethernet interface that makes up the virtual interface. You can specify the time interval, in seconds, at which the statistics are displayed. By default, the statistics are displayed at one-second intervals.
The following example creates a virtual interface:
toaster> vif vif1 create e0 e7a e6b e8
The following example eliminates virtual interface 1:
toaster> vif destroy vif1
The following example displays statistics about virtual interface 1:
toaster> vif stat vif1
