P-335 Plus User's Guide Table 43 Commonly Used Services SERVICE TELNET(TCP:23) TFTP(UDP:69) VDOLIVE(TCP:7000) DESCRIPTION Telnet is the login and terminal emulation protocol common on the Internet and in UNIX environments. It operates over TCP/IP networks. Its primary function is to allow users to log into remote host systems. Trivial File Transfer Protocol is an Internet file transfer protocol similar to FTP, but uses the UDP (User Datagram Protocol) rather than TCP (Transmission Control Protocol). Another videoconferencing solution. 12.7 Default Bandwidth Management Classes and Priorities If you enable bandwidth management but do not configure a rule for critical traffic like VoIP, the voice traffic may then get delayed due to insufficient bandwidth. With the automatic traffic classifier feature activated, the ZyXEL Device automatically assigns a default bandwidth management class and priority to traffic that does not match any of the user-defined rules. The traffic is classified based on the traffic type. Real-time traffic always gets higher priority over other traffic. The following table shows you the priorities between the three default classes (AutoClass_H, AutoClass_M and Default Class) and user-defined rules. 6 is the highest priority.
