PFC Layer 3 Forwarding Engine Tests
TestStaticEntry
The TestStaticEntry test verifies the ability to populate static entries in the Layer 2 MAC address table.
When running the test on the supervisor engine, the diagnostic packet is sent from the supervisor
engine's inband port and performs a packet lookup using the supervisor engine's Layer 2 forwarding
engine. For DFC-enabled modules, the diagnostic packet is sent from the supervisor engine's inband port
through the switch fabric and looped back from one of the DFC ports. The Static Entry feature is verified
during the diagnostic packet lookup by the Layer 2 forwarding engine.

TestFibDevices
The TestFibDevices test verifies whether the FIB TCAM and adjacency devices are functional. One FIB
entry is installed on each FIB TCAM device. A diagnostic packet is sent to make sure that the diagnostic
packet is switched by the FIB TCAM entry installed on the TCAM device. This is not an exhaustive
TCAM device test; only one entry is installed on each TCAM device.

Description
Disruptive for looped-back ports. Disruption is typically less
than one second. Duration of the disruption depends on the
configuration of the looped-back port (for example, Spanning
Tree Protocol).
This test runs by default during bootup or after a reset or OIR.
