Online Diagnostic Tests

This appendix describes the online diagnostic tests and provides recommendations for how to use them.

The online diagnostic tests are included in these categories:

For information about configuring online diagnostic tests refer to Chapter42, “Configuring Online Diagnostics”

Global Health-Monitoring Tests

The global health monitoring tests consist of the following tests:

TestSPRPInbandPing

TestMacNotification

TestSPRPInbandPing

The TestSPRPIinbandPing test detects most runtime software driver and hardware problems on supervisor engines by running diagnostic packet tests using the Layer 2 forwarding engine, the Layer 3 and 4 forwarding engine, and the replication engine on the path from the switch processor to the route processor. Packets are sent at 15-second intervals.

Table A-1 TestSPRPInbandPing Test Attributes
Attribute	Description
Disruptive/Nondisruptive	Nondisruptive.
Recommendation	Do not disable. Test is automatically disabled during CPU-usage spikes in order to maintain accuracy.
Default	On.
Release	12.2(33)SRA and later releases.
Corrective action	Reset the active supervisor engine.
Hardware support	Active and standby supervisor engine.

TestScratchRegister

The TestScratchRegister test monitors the health of application-specific integrated circuits (ASICs) by writing values into registers and reading back the values from these registers. The test runs every 30 seconds. Five consecutive failures causes a supervisor engine to switchover (or reset), if you are testing the supervisor engine, or in the module powering down when testing a module.

Table A-2 TestScratchRegister Test Attributes
Attribute	Description
Disruptive/Nondisruptive	Nondisruptive.
Recommendation	Do not disable.
Default	On.
Release	12.2(33)SRA and later releases.

Hardware support	Supervisor Engine 720, DFC-equipped modules, WS-X6148-FE-SFP, WS-X6148A-GE-TX, and WS-X6148A-RJ-45.

TestMacNotification

The TestMacNotification test verifies that the data and control path between DFC modules and supervisor engines is working properly. This test also ensures Layer 2 MAC address consistency across Layer 2 MAC address tables. The test runs every six seconds. Ten consecutive failures causes the module to reset during bootup or runtime (default). After three consecutive resets, the module powers down.

Table A-3 TestMacNotification Test Attributes
Attribute	Description
Disruptive/Nondisruptive	Nondisruptive.
Recommendation	Do not disable.
Default	On.

Per-Port Tests

The per-port tests consist of the following tests:

TestNonDisruptiveLoopback

TestLoopback

TestActiveToStandbyLoopback

TestTransceiverIntegrity

TestNetflowInlineRewrite

TestNonDisruptiveLoopback

The TestNonDisruptiveLoopback test verifies the data path between the supervisor engine and the network ports of a module. In this test, a Layer2 packet is flooded onto VLAN that contains a group of test ports. The test port group consists of one port per port ASIC channel. Each port in the test port group nondisruptively loops back the packet and directs it back to the supervisor engine’s inband port. The ports in the test port group are tested in parallel.

Table A-4 TestNonDisruptiveLoopback Test Attributes

Hardware support	WS-X6148-FE-SFP, WS-X6148A-GE-TX and WS-X6148A-RJ-45.

TestLoopback

The TestLoopback test verifies the data path between the supervisor engine and the network ports of a module. In this test, a Layer 2 packet is flooded onto a VLAN that consists of only the test port and the supervisor engine’s inband port. The packet loops back in the port and returns to the supervisor engine on that same VLAN.

TestActiveToStandbyLoopback

The TestActiveToStandbyLoopback test verifies the data path between the active supervisor engine and the network ports of the standby supervisor engine. In this test, a Layer 2 packet is flooded onto a VLAN that consists of only the test port and the supervisor engine’s inband port. The test packets are looped back in the targeted port and are flooded back onto the bus with only the active supervisor engines’s inband port listening in on the flooded VLAN.

Fabric Tests

The Fabric tests consists of the following tests:

TestFabricSnakeForward

TestFabricSnakeBackward

TestSynchedFabChannel

TestFabricCh0Health

TestFabricCh1Health

TestFabricSnakeForward

The TestFabricSnakeForward test consists of two test cases: the internal snake test and the external snake test. The internal snake test generates the test packets inside the fabric ASIC and the test data path is limited so that it stays inside the fabric ASIC. The external snake test generates the test packet using the supervisor engine inband port; the test data path involves the port ASIC, the rewrite engine ASIC inside the supervisor engine, and the fabric ASIC. Whether or not the supervisor engine local channel is synchronized to the fabric ASIC determines which test is used. If it is synchronized, the external snake test is used; if it is not, the internal snake test is used. For both tests, only the channels that are not synchronized to any modules are involved in the test. The Forward direction indicates that the snaking direction is from the low-numbered channel to the high-numbered channel.

TestFabricSnakeBackward

The TestFabricSnakeBackward test consists of two test cases: the internal snake test and the external snake test. The internal snake test generates the test packets inside the fabric ASIC, and the test data path is limited so that it stays inside the fabric ASIC. The external snake test generates the test packet using the supervisor engine inband port and the test data path involves the port ASIC, the rewrite engine ASIC inside the supervisor engine, and the fabric ASIC. Whether or not the supervisor engine local channel is synchronized to the fabric ASIC determines which test is used. If it is synchronized, the external snake test is used; if it is not, internal snake test is used. For both tests, only the channels that are not synchronized to any modules are involved in the test. The backward direction indicates that the snaking direction is from the high-numbered channel to the low-numbered channel.

Stress Tests

The stress tests consist of the following tests:

TestTrafficStress

TestEobcStressPing

TestTrafficStress

The TestTrafficStress test stress tests the switch and the installed modules by configuring all of the ports on the modules into pairs, which then pass packets between each other. After allowing the packets to pass through the switch for a predetermined period, the test verifies that the packets are not dropped.

The test is started when the supervisor engine initiates a number of sweep-ping processes (the default is one). The sweep-ping process pings the module with 20,000 SCP-ping packets. The test passes if all 20,000 packets respond before each packet-ping timeout, which is two seconds. If unsuccessful, the test allows five retries to account for traffic bursts on the EOBC bus during the test.
