PFC Layer 3 Forwarding Engine Tests
TestAclDeny
The TestAclDeny test verifies that the ACL deny feature of the Layer 2 and Layer 3 forwarding engine
is working properly. The test uses different ACL deny scenarios such as input, output, Layer 2 redirect,
Layer 3 redirect, and Layer 3 bridges to determine whether or not the ACL deny feature is working
properly.
TestNetflowShortcut
The TestNetflowShortcut test verifies that the NetFlow forwarding functionality of the Layer 3
forwarding engine is working properly. One diagnostic NetFlow entry and adjacency entry is installed,
and a diagnostic packet is sent to make sure it is forwarded according to the rewritten MAC and VLAN
information.
TestQoS
The TestQoS test verifies whether or not the QoS input and output TCAM is functional by programming
the QoS input and output TCAM so that the ToS value of the diagnostic packet is changed to reflect
either input or output.
