Exam 300-208 topic 1 question 7 discussion

The SWISS protocol is a stateless request response protocol that allows NAC Agents which are running on managed clients to discover the Cisco ISE server, and retrieve configuration and operational information. The NAC Agent connects to the Cisco ISE server by sending SWISS unicast discovery packets out on User Datagram Protocol (UDP) port 8905 until a Cisco ISE node that assumes the Policy Service persona sends a response to the client. https://www.cisco.com/en/US/docs/security/ise/1.0/user_guide/ise10_pos_pol.pdf

It should be tcp/udp 8905

ISE Administration Guide 2.6: Create a Native Supplicant Profile to be Used in Client Provisioning Policy You can create native supplicant profiles to enable users to bring personal devices to your Corporate network. Cisco ISE uses different policy rules for different operating systems. Each client provisioning policy rule contains a native supplicant profile, which specifies which provisioning wizard is to be used for which operating system. Before you begin • Configure the CA certificate template in Cisco ISE. • Open up TCP port 8905 and UDP port 8905 to enable Cisco NAC Agent, Cisco NAC Web Agent, and supplicant provisioning wizard installation. For more information on port usage, see the "Cisco ISE Appliance Ports Reference" appendix in the Cisco Identity Services Engine Hardware Installation Guide
