Configure ISE to authenticate both domain and internal users using an identity source sequence, combining internal user database and Active Directory with PEAP-MSCHAPv2, then apply a shared authorization rule.

Examine phased deployment for secure network services: monitor mode in phase one, then low-impact or closed mode in phase two, using authentication open and pre-authentication acl to govern access.

Enable monitor mode by configuring authentication open on GigabitEthernet0/2, then misconfigure allowed protocols to allow PEAP with EAP-GTC while EAP-MSCHAPv2 is used, causing failure, yet full network access remains granted.

Learn how to implement low-impact mode using a pre-authentication ACL to grant limited access when authentication fails, with DNS allowed and ICMP denied.

implement closed mode by removing the pre-authentication acl and authentication open command on the switch port, then verify that failed authentication yields no network access.

Demonstrate handling a server dead in monitor mode, showing RADIUS dead tests, quarantine, VLAN authorization behavior, and reinitializing authentication when ISE becomes reachable.

Shows how a low-impact mode switchport uses a pre-authentication ACL to allow only DNS and DHCP traffic while awaiting RADIUS authentication, and a dead RADIUS leads to VLAN 100 authorization.

Demonstrates a server dead scenario in closed mode deployment, showing how a switch port in closed mode handles no response from ISE and reinitializes dot1x when RADIUS server comes alive.

Create user defined equivalents of system-defined PermitAccess and DenyAccess by setting Access_Accept and Access_Reject, apply them to authorization rules, and verify with live logs and 802.1x session tests.

Learn to create downloadable access lists (DACLs) for domain and internal users and map them to authorization profiles with access_accept, then verify with logs and test access.

Explore how a downloadable ACL is applied inbound on a switch port during 802.1x, using an authorization profile with a deny ip any any DACL restricting domain user traffic.

Configure an authorization profile using Filter-ID to reference a switch ACL, create My_Filter with Access_Accept, apply it to domain user rule, and verify user1 can only ping 10.10.10.30 after reauthentication.

Configure an authorization profile 'My_VLAN' with vlan 100 and access type to 'Access_Accept', enabling dynamic VLAN assignment from a VLAN 10 port during reauthentication.

Explore how 802.1x enables both user and machine authentication in Windows, validating domain computers via machine accounts and passwords or certificates for secure network access.

Enable machine authentication on ISE, define Login_Prompt_Profile with WasMachineAuthenticated to grant DHCP, DNS, and Active Directory access at login; explain PEAP separation and workaround.
