PFC Layer 3 Forwarding Engine Tests
TestL3Capture2
The TestL3Capture2 test verifies that the Layer 3 capture (capture 2) feature of the Layer 3 forwarding
engine is working properly. This capture feature is used for ACL logging and VACL logging. One
diagnostic FIB and adjacency entry with a capture 2 bit set is installed and a diagnostic packet is sent to
make sure that the diagnostic packet is forwarded according to the capture bit information.
TestAclPermit
The TestAclPermit test verifies that the ACL permit functionality is working properly. An ACL entry
permitting a specific diagnostics packet is installed in the ACL TCAM. The corresponding diagnostic
packet is sent from the supervisor engine and looked up by the Layer 3 forwarding engine to make sure
that it hits the ACL TCAM entry and gets permitted and forwarded appropriately.

This test can also be used as a health-monitoring test. Use as
a health-monitoring test if the destination IP address is being
rewritten (for example, if you are using NAT).
Default This test runs by default during bootup or after a reset or OIR.
Release 12.1(13)E, 12.2(14)SX.
