Within aMobility Domain, the WX switches exchange information and other typesof traffic, depending on your configuration of AAA and variousmanagement services.Table 12 provides a summary of the traffic ports typically used by aMobility Domain and its associated AAA and management functions.Table 12 Traffic Ports Used for AAA Servers and Management ServersProtocol Port FunctionIP/UDP (17) 1812 RADIUS authentication(default setting)IP/UDP (17) 1813 RADIUS accounting (defaultsetting)IP/TCP (6) 443 Secure Sockets Layerprotocol (SSL) managementusing Web ManagerIP/TCP (6) 8889 SSL management using3WXMIP/TCP (6) 23 Telnet managementIP/UDP (17) 161 SNMP get and set operationsIP/UDP (17) 162 SNMP trapsIP/ICMP (1) N/A Several types (for example,ping)IP/UDP (17) 123 Network Time Protocol (NTP)IP/UDP (17) 53 Domain Name Service (DNS)
