Description
Factory
Default
Delete
To delete a mapping, check this box and press save. The entry will be deleted in the
stack.
-
IP Address
Indicates the subnet's IP address (Any of the subnet's host addresses can be also provided
here, the application will convert it automatically).
0.0.0.0
Mask Length
Indicates the subnet's mask length.
24
VLAN ID
Indicates the VLAN ID the subnet will be mapped to. IP Subnet to VLAN ID is a unique
matching.
1
Port Members
A row of check boxes for each port is displayed for each IP subnet to VLAN ID mapping
entry. To include a port in a mapping, simply check the box. To remove or exclude the
port from the mapping, make sure the box is unchecked. By default, no ports are
members and all boxes are unchecked.
Unclicked
Click
Add New Entry
to add a new IP subnet to VLAN ID mapping entry. An empty row is added to the table, and the mapping
can be configured as needed. Any IP address/mask can be configured for the mapping. Valid values for the VLAN ID are 1 to
4095. The IP subnet to VLAN ID mapping entry is enabled when you click on "
Save
" button. The
Delete
button can be used
to undo the addition of new mappings. The maximum possible IP subnet to VLAN ID mappings is limited to 128.
Click
Save
button to save the setting configuration. Click
Reset
button to keep to the original setting. Check the
Auto-refresh
box to refresh the page automatically. The automatic refresh occurs every 3 seconds. Otherwise, click
Refresh
box to refresh
the page immediately.

QoS
Quality of Service (QoS) is the ability to provide different priority to different applications, users, or data flows. QoS guarantees
a certain level of performance to a data flow by using the following metrics: transmitted bit rate, bit error rate, delay, jitter, and
probability of packet dropping. QoS guarantees are important if the network capacity is insufficient, especially for application
that requires certain bit rate and is delay sensitive. For any network that is best effort, QoS cannot be guaranteed, except that
resource is more than sufficient to serve users.
Controlling network traffic needs a set of rules to help classify different types of traffic and define how each of them should
be treated as they are being transmitted. This managed switch can inspect both 802.1p Class of Service
(CoS) tags and DiffServ
tags called Differentiated Services Code Point (DSCP) to provide consistent classification.

Port Classification
The Port Classification webpage shown in Figure 2.94 allows the user to configure the basic QoS Ingress Classification
settings for all of managed switch ports. Table 2.83 provides the descriptions of the setting parameters of QoS Port
Classification.
