The Network test verifies the following:
Checks all the networking hardware on the system (controllers). The machine under test must be attached to a network with at least one other system on the network.
Performs the Ethernet connector test (Internal, External). You can select Internal/External loopback from the GUI or TTY for the Network Test. By default, Loopback:Auto is selected. Check for the proper connector cable connection before enabling the External Loopback option (see Test Setup). If Loopback:Auto is selected, the test automatically detects the internal or external loopback type.
Performs tests on the Infiniband host channel adapter (HCA). Verifies operation of associated chips and components. Verifies chip firmware/hardware revision. Internal Loopback is supported. DDR memory and flash memory verification is performed. The Infiniband host channel adapter test is supported only when the port does not have any cables connected to it.
You must plumb down the ibdXX interfaces to perform Infiniband host channel adapter (HCA) validation without live network connection. Use the following commands to plumb down ibdXX interfaces:
#ifconfig ibdXX down
#ifconfig ibdXX unplumb
Where XX is the instance number of the interface. If ibdXX interfaces are plumbed up, then the software will validate IP over IB functionality over ibdXX interfaces.
Back_To_Back subtest provides a capability to test two ports connected by a supported network cable. Back_To_Back subtest runs in mutually exclusive mode, no other subtest will run on the back to back port pair.
Your system must meet the following requirements to run the Back_To_Back subtest:
Ports must be plumbed down and connected back to back.
Back_To_Back subtest is supported only on interface pair of same driver.
The following entry in the sunvts.conf configuration file is required to run Back_To_Back subtest on nxge2 and nxge3.
Network_Back_To_Back nxge2=nxge3
When a Network test starts, the kstat log file is created under the directory /var/sunvts/log/networktest.kstat/, with a filename as interface_name. This file contains the initial kstat entry. During the test, if there is a packet drop, the following alert message is displayed.
Packet(s) drop detected on <interface>, see/var/sunvts/log/networktest.kstat/<interface> for details
The maximum size of the kstat log file is 5MB. If the file size is more than 5MB then the older kstat data is moved to a new file by the name interface_name.old. By default, the kstat logging feature is enabled. For more information on how to enable this feature. see Network Test Configuration File Parameters.
