SISE Policy Enforcement Practice Question
A user is failing to receive the expected dACL. The ISE logs show the correct authorization rule was matched, but the dACL is not applied. What is the most likely cause?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The Authorization Profile lacks the correct cisco-av-pair attribute
If the rule matches but the ACL doesn't apply, verify the dACL content or the RADIUS attributes being sent; however, ensure the 'dACL Name' attribute is properly defined in the Authorization Profile.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
The dACL is not assigned to the correct interface on the switch
Why it's wrong here
ISE pushes the dACL, it does not require interface configuration for the object itself.
- ✓
The Authorization Profile lacks the correct cisco-av-pair attribute
Why this is correct
If the dACL name is not correctly mapped in the profile as a RADIUS attribute, the switch will not know which ACL to apply.
- ✗
The user is in the wrong AD group
Why it's wrong here
If the rule matched, the group condition was satisfied.
- ✗
The device is in the wrong network device group
Why it's wrong here
NDG doesn't prevent dACL application if the rule is matched.

AAA Protocol Comparison
| Protocol | Port(s) | Encryption | Transport | Primary Use |
|---|---|---|---|---|
| RADIUS | 1812 / 1813 | Password only | UDP | Network access control |
| TACACS+ | 49 | Full packet | TCP | Device administration |
| Diameter | 3868 | Full session | TCP / SCTP | Carrier / mobile networks |
| 802.1X | — | EAP-based | Layer 2 | Port-based access control |
TACACS+ encrypts the entire packet; RADIUS only encrypts the password field — a key exam distinction.
