Test tab
The Test tab allows you to run external and internal loopback tests on the port.
To open the Test tab:
- On the device view, select a port or multiple ports.
- From the Device Manager menu bar, choose Edit > Port.
| The Port dialog box opens with the Interface tab displayed. |
- Click the Test tab.
The table below describes the Test tab items.
|
Ext. Loopback
|
Specifies an external loopback test, which requires an external loopback connector. This test changes the AdminStatus of the port to up. The CPU then sends data out the port and expects to see the same data returned. The electronics of the port's data path including the transceiver are tested.
|
Int. Loopback
|
Specifies an internal loopback test, which changes the AdminStatus of the port to testing (internal loopback mode). The CPU then sends data to the port, where it is looped back at the PHY. The electronics of the port's data path up to the transceiver are tested.
After the test is stopped, the port AdminStatus stays set to testing, and you must manually change it to up.
|
Stop
|
Stops either loopback test.
|
Result
|
The result of the most recently run (or current) test:
- None
- Success
- InProgress
- NotSupported
- unAbleToRun
- Aborted
- Failed
The code contains more specific information on the test result (for example, an error-code after a failed test):
- NoReceive (timeout on a send)
- BadSeq (packets received out of sequence)
- BadLen (packet length mismatch)
- BadData (packet data mismatch)
|
Code
|
This object contains a code that provides more specific information on the test result (for example, an error-code after a failed test). Error codes and other values this object may take are specific to the type of interface and/or test. The value may have the semantics of either the AutonomousType or InstancePointer textual conventions as defined in RFC 1443. The identifier: testCodeUnknown OBJECT IDENTIFIER ::=
{ 0 0 } is defined for use if no additional result code is available.
|
PassCount
|
The number of iterations the loopback test completed successfully.
|
FailCount
|
The number of iterations the loopback test failed.
