Configuring and Starting a Test

Ethernet Tester Analyzer 45

RFC 2544 General Settings

 ID: Enter the VLAN ID. The accepted range is 0 to 4095. The 12-bit

VLAN identifier is a number, that explicitly defines VLAN to which the

packet belongs.

The null VLAN ID indicates that the tag header contains only user

priority information and no VLAN identifier is present in the frame.

If the VLAN ID is set to 1, then while transmitting through the router’s

port, the VLAN ID will be automatically set equal to the VLAN ID of this

port.

 Priority: Select the VLAN Priority. Eight values of priority ([1]) are

supported.

Correspondence between priority and traffic type are as follows:

Priority 0 is reserved for the best transmission and is assigned if none

other class has been specified. Priority values 1 to 3 are intended for

use with different tasks from the streaming applications to the FTP

traffic that can cope with possible data loss. Priority values 4 and 5 can

be used for latency sensitive traffic such as video or speech.

Priority values 6 and 7 (Internetwork Control and Network Control

traffic types) are intended for network management messages.
