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 and output Layer 2
redirect, Layer 3 redirect, and Layer 3 bridges.
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.
