2.
Select a check box to specify how the table is to be queried. The possible field types are:
•
Port
. Specifies the interface for which the table is queried. Select an interface from the
drop-down list.
•
VLAN ID
. Specifies the VLAN ID for which the table is queried. Enter an existing VLAN
ID.
•
MAC Address
. Specifies the MAC address for which the table is queried. Enter an
existing MAC address.
3.
Click
Apply
to query the table entries. The information that is returned from the query is
displayed as follows:
•
ID
. Shows the table entry ID.
•
Port
. Shows the interface to which the address is assigned.
•
MAC Address
. Shows the MAC address to which the address is assigned.
•
VLAN ID
. Shows the VLAN ID to which the address is assigned.
•
Dynamic/Static
. Shows whether the entry is dynamic or static.

Chapter 5
Configuring QoS and Security
This chapter describes how to use the QoS tab and the Security tab:
•
“Using the QoS Tab
”
•
“Using the Security Tab
”
Using the QoS Tab
The navigation tabs on the top of the home page include a QoS tab that lets you manage your
GS108T Gigabit Smart Switch using features under the following main menu commands and
subcommnands:
•
“CoS
”
•
“Basic—QoS Global Configuration
”
•
“Basic—Rate Limit
”
•
“Advanced—801.1p to Queue Mapping
”
•
“Advanced—DSCP Priority Mapping
”
The sections that follow in this chapter cover these features and tell you how to configure them in
the GS108T Smart Switch.
CoS
The class of service (CoS) menu lets you classify specific traffic at the Layer 2 level by
manipulating the CoS bits, thereby allowing you to configure quality of service (QoS).
Basic—QoS Global Configuration
There are two possible priority tag settings for the QoS; that is, there are two QoS modes:
•
802.1p-based
. The eight priority tags that are specified in IEEE 802.1p are p0 to p7. The QoS
setting lets you map each of the eight priority levels to one of four internal hardware priority
queues: High, Normal, Low, and Lowest.

Configuring QoS and Security
v1.0, December 2007
•
DSCP-based
. The six most significant bits of the DiffServ field are called the Differentiated
Services Code Point (DSCP) bits. You can map the DSCP value to one of the eight priority
levels (p0 to P7) of IEEE 802.1p. Then, you can assign the IEEE 802.1p priority level to one
of the four internal hardware queues.
The switch empties the four hardware priority queues in order, beginning with the highest priority
queue to the lowest priority queue. Each hardware queue transmits all of the packets in its buffer
before permitting the next lower priority to transmit its packets.
To configure the QoS mode:
1.
Select QoS > CoS > Basic > QoS Global Configuration. A screen similar to the following
displays.
2.
Select the
802.1p Based
or the
DSCP Based
radio button to determine the QoS mode.
3.
Click
Apply
to confirm any settings changes.
Basic—Rate Limit
The Rate Limit screen, which is also referred to as the Rate Control Setting screen, lets you control
the bandwidth of ingress (incoming) and egress (outgoing) traffic for a specific port. To assign
bandwidth limits:
1.
Select QoS > CoS > Basic > Rate Limit. A screen similar to the following displays.

2.
You can make changes to the bandwidth limits for an individual port, for a group of ports, or
for all ports simultaneously:
•
To change the bandwidth limits for an individual port, select the check box to the left of its
port number, and then select bandwidth limits.
•
To change the bandwidth limits for a group of ports, select the check boxes to the left of
their port numbers, and then select the bandwidth limits.
•
To change the bandwidth limits for all ports simultaneously, select the check box at the
top of the column of check boxes, and then select the bandwidth limits.
The following port configuration information is displayed. All fields are configurable:
•
Port
. Specifies the port number.
•
Ingress Rate
. Specifies the rate limitation of incoming traffic in this port. The possible
values in bits per second (bps) are:
–
512K bps, 2M bps, 4M bbps, 10M bps, 20M bps, 40M bps, 60M bps, 100M bps,
200M bps, 400M bps, and 1000M bps.

Note:
You can also enter the interface number (that is, the port number) in the
GO
TO INTERFACE
field, and then click
GO
.
