Figure 9-8. Access Rule Configuration window (Ethernet)

To set the Access Rule for Ethernet, adjust the following parameters and click Apply.

Parameters Description

Profile ID

This is the identifier number for this profile set.

Mode Select Permit to specify that the Switch, according to any additional rule, forwards the

packets that match the access profile added (see below).

Select Deny to specify that packets that match the access profile are not forwarded by the

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 for this access. This value can be set from 1 - 65535.

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) or IP address.

• 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.

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 Ethernet Rule.

For more information on priority queues, CoS queues and mapping for 802.1p, see the QoS

section of this manual.
