SISE Policy Enforcement Practice Question
An administrator needs to implement SGT-based access control where SGT 10 (Finance) cannot communicate with SGT 20 (HR). What is the mandatory prerequisite on the ISE policy side?
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
✓
Enable SGT propagation on the policy set
Before SGTs can be used, the TrustSec matrix must be defined and the ISE must be configured to send SGT information in RADIUS Access-Accept messages.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Manually map IP to SGT on all switches
Why it's wrong here
ISE provides dynamic SXP or Cisco TrustSec SGT mapping.
- ✗
Configure the SGACL on the client
Why it's wrong here
SGACLs are enforced on the enforcement device, not the client.
- ✓
Enable SGT propagation on the policy set
Why this is correct
This ensures the SGT value is passed via the RADIUS attribute 217 to the network device.
- ✗
Create a dACL with SGT 10
Why it's wrong here
dACLs are for IP-based filtering, not SGT-based filtering.
Quick reference
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.
