166 Chapter 15 Bandwidth Management

15.7 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.

Table 68 Bandwidth Management Priority with Default Classes

CLASS TYPE PRIORITY

AutoClass_H 5

User-defined with medium priority 4

AutoClass_M 3

User-defined with low priority 2

TELNET(TCP:23) 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.

similar to FTP, but uses the UDP (User Datagram Protocol) rather

than TCP (Transmission Control Protocol).
