Managing Network Adapters

Modifying vNIC Properties

	Command or Action	Purpose
		secondary interface if there are communication
		problems.
Step 18	Server /chassis/adapter/host-eth-if # set	After a vNIC has started using its secondary interface,
	uplink-failback-timeout seconds	this setting controls how long the primary interface
		must be available before the system resumes using the
		primary interface for the vNIC.
		Enter a number of seconds between 0 and 600.
Step 19	Server /chassis/adapter/host-eth-if #	Enters the interrupt command mode.
	scope interrupt
Step 20	Server	Specifies the number of interrupt resources. The range
	/chassis/adapter/host-eth-if/interrupt #	is 1 to 514; the default is 8. In general, you should
	set interrupt-count count	allocate one interrupt resource for each completion
		queue.

Step 21	Server
	/chassis/adapter/host-eth-if/interrupt #
	set coalescing-time usec

The time to wait between interrupts or the idle period that must be encountered before an interrupt is sent.

The range is 1 to 65535 microseconds; the default is 125. To turn off coalescing, enter 0 (zero).

Step 22	Server
	/chassis/adapter/host-eth-if/interrupt #
	set coalescing-type {idle min}

Step 23	Server
	/chassis/adapter/host-eth-if/interrupt #
	set interrupt-mode {intx msi msix}

Step 24	Server
	/chassis/adapter/host-eth-if/interrupt #
	exit
Step 25	Server /chassis/adapter/host-eth-if #
	scope recv-queue

The coalescing types are as follows:

•idle —The system does not send an interrupt until there is a period of no activity lasting as least as long as the time specified in the coalescing time configuration.

•min —The system waits for the time specified in the coalescing time configuration before sending another interrupt event. This is the default.

Specifies the Ethernet interrupt mode. The modes are as follows:

•intx —Line-based interrupt (PCI INTx)

•msi —Message-Signaled Interrupt (MSI)

•msix —Message Signaled Interrupts with the optional extension (MSI-X). This is the recommended and default option.

Exits to the host Ethernet interface command mode.

Enters receive queue command mode.
