Field Name
Name:
A user-assigned name for a specific code point.
Code Point:
The value of 6-bit DiffServ Code Point. Valid values are 0-63.
Priority:
The queuing priority of a packet tagged with this DSCP.
802.1p Marking:
When an IP packet is generated by Multinet4 it is assigned a
DSCP (by default, Best Effort 0x00 is used).The packet may
optionally be assigned an 802.1p priority based on the DSCP as
specified by this field.This field can take the value 0-7 or the
special value "None," meaning that no mapping between DSCP
and 802.1p priority is implemented and thus no 802.1p marking
is made.This field has no effect when the IP packet being
processed is not an Ethernet frame.
NOTE: The mapping is performed only for packets
generated by Multinet4. Bridged packets retain whatever
markings they had when they were received.
Delete:
Set the Delete checkbox in a row in the Existing Profiles table
and click Apply Settings to delete that entry.
4.7.0.2 802.1p
The 802.1p standard supplies QoS at layer 2 by using the 3-bit user_priority header field.
The 802.1p standard defines eight classes of service.This screen enables you to map
Ethernet frames marked with a specific 802.1p priority into the four available switch
priority queues.
