D-Link DES-3250TG manual Mode, Access ID, Priority Replace Dscp

D-Link DES-3250TG Standalone Layer 2 Switch

Configure the following Access Rule Configuration settings for IP:

Parameter	Description
Profile ID	This is the identifier number for this
	profile set.
Mode	Select Permit to specify that the packets
	that match the access profile are
	forwarded by the Switch, according to
	any additional rule added (see below).
	Select Deny to specify that packets that
	do not match the access profile are not
	forwarded by the Switch and will be
	filtered.
Access ID	Type in a unique identifier number for
	this access. This value can be set from 1
	- 50.
Type	Selected profile based on Ethernet
	(MAC Address), IP address or Packet
	Content Mask.

Priority (0-7)

Replace Dscp (0-63)

Ethernet instructs the Switch to examine the layer 2 part of each packet header.

IP instructs the Switch to examine the IP address in each frame's header.

Packet Content Mask instructs	the
Switch to examine the packet header

This parameter is specified if you want to re-write the 802.1p default priority previously set in the Switch, which is used to determine the CoS queue to which packets are forwarded to. Once this field is specified, packets accepted by the Switch that match this priority are forwarded to the CoS queue specified previously by the user.

Replace priority with − Click the corresponding box if you want to re-write the 802.1p default priority of a packet to the value entered in the Priority field, which meets the criteria specified previously in this command, before forwarding it on to the specified CoS queue. Otherwise, a packet will have its incoming 802.1p user priority re-written to its original value before being forwarded by the Switch.

For more information on priority queues, CoS queues and mapping for 802.1p, see the QoS section of this manual.

Select this option to instruct the Switch to replace the DSCP value (in a packet that meets the selected criteria) with the value entered in the adjacent field.
