Chapter: Cisco SNS-3400 Series Appliance Ports Reference
Cisco SNS-3400 Series Appliance Ports Reference
This appendix lists the TCP and User Datagram Protocol UDP ports that Cisco ISE uses for intranetwork communications with external applications and devices.
Table C-1 lists the ports by TCP and UDP port number, identifies the associated feature, service, or protocol, and describes any specific port-related information that applies to the four Gigabit Ethernet ports: GbEth0, GbEth1, GbEth2, and GbEth3. The Cisco ISE ports listed in this table must be open on the corresponding firewall. The ports list provides information that can be useful when configuring a firewall, creating access control lists (ACLs), and configuring services on a Cisco ISE network.
- Cisco ISE management is restricted to Gigabit Ethernet 0.
- RADIUS listens on all network interface cards (NICs).
- All NICs can be configured with IP addresses.

1.Because Inline Posture nodes do not support the Administration persona, they will not have access to this port. 2.NMAP OS Scan uses ports 0.65535 to detect endpoint operating system |
Ports to be Used for OCSP and CRL
For the Online Certificate Status Protocol services (OCSP) and the Certificate Revocation List (CRL), the ports are dependent on the CA Server or service hosting OCSP/CRL although the Cisco ISE Services and ports table above lists basic ports that are used in Cisco ISE.
For the OCSP, the default ports that can be used are TCP 80/ TCP 443. Cisco ISE admin portal expects http-based URL for OCSP services, and so, TCP 80 would be the default. You can also use non-default ports.
For the CRL, the default protocols include HTTP, HTTPS, and LDAP and the default ports would naturally be 80, 443, and 389 respectively. The actual port is contingent on the CRL server.
