ISE Authorization Methods - Basic

• ISE authorization rules processing order
• Takes place only after successful authentication
• Match condition (identity store type, profiling, etc)
• Assign authorization profile
• By default scans sequentially but can be changed to Multiple Matched Rules applied
• Typical use case when you create rule per role (e.g. AD_DACL, NETWORK_DACL, SERVERS_DACL, etc)
• In this case, network engineer can get AD_DACL and NETWORK_DACL
• Another option is to configure one DACL for network users, another DACL for server users, etc
• Its independent from authentication type (MAB, Dot1x or CWA)
• Authorization options
• VLAN Assignment
• You can assign Data VLAN and/or allow Voice VLAN access
• Data VLAN
• It will override the locally configured VLAN on the switch port
• VLAN is provided to NAD using VSA Tunnel-Private-Group-ID
• If no dVLAN is configured, static switchport vlan will be used
• Voice VLAN
• It will grant IP Phones access to connect to the network using the configured voice vlan (no new vlan assignment)
• You need to enable 'Voice Domain Permission' under the authorization policy
• ISE will include the VSA 'cisco-av-pair: device-traffic-class=voice' in ACCESS-ACCEPT to indicate that this is the voice vlan
• ACL
• dACL
• This is Cisco proprietary because it uses Cisco-specific Radius attributes
• ACL is configured in ISE and pushed to the switch
• Filter-ID ACL
• This is IETF standard
• The ACL is configured on the switch
• ISE will provide the switch with ACL name to be applied to the port
• Per-User ACL
• This is Cisco proprietary
• ACL can be configured on ISE and pushed to the switch
• ACL can be configured on the switch and ISE will provide the name to the switch
• IP Address
• ISE can provide IP address to endpoints part of the authorization process using VSA Framed-IP
• Similarly, ISE can provide session time to NAD using Session-Timeout
