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 NBG334S 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.

DESCRIPTION
Remote Execution Daemon.
Remote Login.
Remote Telnet.
The Real Time Streaming (media control) Protocol (RTSP) is a
remote control for multimedia on the Internet.
Simple File Transfer Protocol.
Simple Mail Transfer Protocol is the message-exchange standard for
the Internet. SMTP enables you to move messages from one e-mail
server to another.
Simple Network Management Program.
Traps for use with the SNMP (RFC:1215).
Structured Query Language is an interface to access data on many
different types of database systems, including mainframes, midrange
systems, UNIX systems and network servers.
Secure Shell Remote Login Program.
Stream Works Protocol.
Syslog allows you to send system logs to a UNIX server.
Login Host Protocol used for (Terminal Access Controller Access
Control System).
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.
