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 (
) 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.
