16.9.3

Description (partial)

Symptom:
Ip verify source is used to dynamically create ACLs on a per-port basis (these can't be viewed in the running-configuration). Any traffic which doesn't match the binding entries is dropped in hardware. However, the port won't go into the err disable state ? it won't even display a violation message at the console.

After Applying "ip verify source" to interfaces all SGACL denied traffic  is allowed

Conditions:
entries present in  ip source binding and sh ip verify source
