DES-3028 DES-3028P DES-3028G DES-3052 DES-3052P Layer 2 Fast Ethernet Managed Switch
Switch and will be filtered.
Rx Rate (No Limit:0)
Enter an Rx Rate in kbps.
Access ID (1-
65535) Type in a unique identifier number between
1
and
65535
for this access or use Auto Assign .
Auto Assign
– Checking this field will instruct the Switch to automatically assign an Access ID
for the rule being created.
Type
Selected profile based on
Ethernet
(MAC Address),
IP
address or
Packet Content Mask
.

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.
Priority (0-7)
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.
When
replace priority
is selected, the Switch will rewrite the 802.1p default priority of a packet to
the value entered into the priority field. This value will meet the criteria specified, before being
forwarded on to a 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. The
replace priority
feature can only be used with DSCP value and cannot be used with the Packet Content Rule.
For more information on priority queues, CoS queues and mapping for 802.1p, see the QoS
section of this manual.
Offset This field will instruct the Switch to mask the packet header beginning with the offset value
specified:

You can specify an offset of between 0 and 76 bytes.
Port Number Enter the switch port number(s) to which you wish this rule to apply.
Time Range Enter the specific time range when this access rule will be implemented on the Switch.
