Online Diagnostic Tests
This appendix describes the online diagnostic tests and provides recommendations for how to use them.
Note
•For information about configuring online diagnostic tests refer to Chapter 55 "Configuring Generic Online Diagnostics."
•We recommend that before you enable any online diagnostics tests that you enable the logging console/monitor to see all warning messages.
•We recommend that when you are running disruptive tests that you only run the tests when connected through console. When disruptive tests are complete a warning message on the console recommends that that you reload the system to return to normal operation: Strictly follow this warning.
•While tests are running, all ports are shut down as a stress test is being performed with looping ports internally and external traffic might skew the test results. The entire switch must be rebooted to bring the switch to normal operation. When you issure the command to reload the switch, the system will ask you if the configuration should be saved.
•Do not save the configuration.
•If you are running the tests on a supervisor engine, after the test is initiated and complete, you must reload or power down and then power up the entire system.
•If you are running the tests on a module that is not the supervisor engine, after the test is initiated and complete, you must reset the module.
The online diagnostic tests are included in these categories:
•Global Health-Monitoring Tests
•PFC Layer 2 Forwarding Engine Tests
•DFC Layer 2 Forwarding Engine Tests
•PFC Layer 3 Forwarding Engine Tests
•DFC Layer 3 Forwarding Engine Tests

Global Health-Monitoring Tests
The global health monitoring tests consist of the following tests:
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. Ten consecutive failures of the test results in failover to the redundant supervisor engine (default) or reload of the supervisor engine if a redundant supervisor engine is not installed.
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.
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.
Per-Port Tests
The per-port tests consist of the following tests:
TestNonDisruptiveLoopback
The TestNonDisruptiveLoopback 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 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.
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.
TestTransceiverIntegrity
The TestTransceiverIntegrity test is a security test performed on the transceiver during transceiver online insertion and removal (OIR) or module bootup to make sure that the transceiver is supported.
TestNetflowInlineRewrite
The TestNetflowInlineRewrite test verifies the NetFlow lookup operation, the ACL permit and deny functionality, and the inline rewrite capabilities of the port ASIC. The test packet will undergo a NetFlow table lookup to obtain the rewrite information. The VLAN and the source and destination MAC addresses are rewritten when the packet reaches the targeted port.

TestEgressSpan
The TestEgressSpan test verifies that the egress SPAN replication functionality of the rewrite engine for both SPAN queues is working properly.
Fabric Tests
The Fabric tests consists of the following tests:
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.
TestSynchedFabChannel
The TestSynchedFabChannel test periodically checks the fabric synchronization status for both the module and the fabric. This test is available only for fabric-enabled modules. This test is not a packet-switching test so it does not involve the data path. This test sends an SCP control message to the module and fabric to query the synchronization status.
TestFabricCh0Health
The TestFabricCh0Health test constantly monitors the health of the ingress and egress data paths for fabric channel 0 on 10-gigabit modules. The test runs every five seconds. Ten consecutive failures are treated as fatal and the module resets; three consecutive reset cycles may result in a fabric switchover.
TestFabricCh1Health
The TestFabricCh1Health test constantly monitors the health of the ingress and egress data paths for fabric channel 1 on 10-gigabit modules. The test runs every five seconds. Ten consecutive failures are treated as fatal and the module resets; three consecutive reset cycles may result in a fabric switchover.
Exhaustive Memory Tests
The exhaustive memory tests include the following tests:
Note Because the supervisor engine must be rebooted after running memory tests, run memory tests on the other modules before running them on the supervisor engine. For more information about running on-demand online diagnostic tests see the "Configuring On-Demand Online Diagnostics" section.
TestFibTcamSSRAM
The TestFibTcamSSRAM test checks the FIB TCAM and Layer 3 Adjacency SSRAM memory.
TestAsicMemory
The TestAsicMemory test uses an algorithm to test the memory on a module.
TestAclQosTcam
The TestAclQosTcam test tests all the bits and checks the location of both ACL and QOS TCAMs on the PFC3BXL and PFC3B. It is not supported on the PFC3A.
TestNetflowTcam
The TestNetflowTcam test tests all the bits and checks the location of the Netflow TCAM.
TestQoSTcam
The TestQoSTcam test performs exhaustive memory tests for QoS TCAM devices.
IPSEC Services Modules Tests
The IPSEC Services Modules Tests include the following tests:
TestIPSecClearPkt
The TestIPSecClearPkt test sends a packet through the switch fabric or bus from the supervisor engine inband port through to the crypto engine. The packet is sent back without encryption from the crypto engine to the supervisor engine in-band port. The packet is checked to verify that the encryption is not done and that the packet data fields are reserved. The Layer 2 lookup drives the packet between the supervisor in-band port and the crypto engine.
TestHapiEchoPkt
The TestHapiEchoPkt test sends a Hapi Echo packet to the crypto engine using the control path. After the Hapi Echo packet is sent to the crypto engine, it is echoed back from the crypto engine. The packet is sent from the supervisor engine inband port to the crypto engine using index-direct and is sent back using broadcast to a diagnostic VLAN.
TestIPSecEncryptDecryptPkt
The TestIPSecEncryptDecryptPkt test checks the encryption functionality by exchanging a packet between the supervisor engine in-band port and the crypto engine of the IPSec services modules (WS-SVC-IPSEC, SPA-IPSEC) using the switch fabric or bus (whichever is applicable). After several exchanges, the packet is checked to verify that the original data is preserved after the encryption and decryption process performed by the crypto engine. The Layer 2 lookup drives the packet between the supervisor in-band port and the crypto engine.
Stress Tests
The stress tests consist of the following tests:
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.
TestEobcStressPing
The TestEobcStressPing test stress tests a module's EOBC link with the supervisor engine. 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.
Critical Recovery Tests
The critical recovery tests consist of the following tests:
The TestFabricCh0Health and TestFabricCh1Health tests are also considered critical recovery tests. See the "Fabric Tests" section for a description of these tests.
TestL3HealthMonitoring
The TestL3HealthMonitoring test triggers a set of diagnostic tests involving IPv4 and IPv6 packet switching on a local DFC whenever the system tries to self-recover from a detected hardware fault. The tests shut down the front panel port (usually port 1) for testing purposes. If the diagnostic tests are not passing, it is an indication that the hardware fault cannot be fixed and a self-recovery sequence will be applied again
TestTxPathMonitoring
The TestTxPathMonitoring test sends index-directed packets periodically to each port on the Supervisor Engine 720 and WS-X67xx series modules to verify ASIC synchronization and correct any related problems. The test runs every two seconds.
TestSynchedFabChannel
The TestSynchedFabChannel test periodically checks the fabric synchronization status for both the module and the fabric. This test is available only for fabric-enabled modules. This test is not a packet-switching test so it does not involve the data path. This test sends an SCP control message to the module and fabric to query the synchronization status.
General Tests
The general tests consist of the following tests:
ScheduleSwitchover
The ScheduleSwitchover test allows you to trigger a switchover at any time using the online diagnostics scheduling capability.
TestFirmwareDiagStatus
The TestFirmwareDiagStatus test displays the results of the power-on diagnostic tests run by the firmware during the module bootup.
