Advanced Configuration
Wreless-G Busness Ethernet Brdge
You can configure the Administrative Status and Flow
Control of the five Ethernet ports. The link speed and duplex
settings are done automatically through auto-negotiation.
Flow control should be enabled to control network traffic
during periods of congestion and prevent the loss of
packets when port buffer thresholds are exceeded. The
flow control feature is based on IEEE 802.3x which uses
control frames to throttle the outgoing packets from a
switch port to another IEEE 802.3x-compatible device.
This feature is not available on the wireless interface.
Admnstratve Status
To configure the administrative
status of the port, select either
Up
(default) or
Down
. A
port can be shut down even if it is physically connected.
Flow Control
To configure flow control for the port, select
either
Enabled
or
Dsabled
(default).
NOTE:
Flow Control should be disabled when
QoS mode (802.1p, TOS, or DSCP) is configured.
QoS mode allows priority differentiation during
congestion instead of throttling off the traffic.
Lnk
Displays the port’s link status (UP or DOWN), which
is a combination of the Administrative Status and the
physical link connection.
Duplex
Displays the port’s duplex mode through auto-
negotiation if the link is UP.
Speed
Displays the port’s speed in Mbps through auto-
negotiation if the link is UP.

Switch > Port Mirroring
Use this screen to configure Port Mirroring, which lets you
mirror traffic to/from any port (including wireless) to Port 1
for real-time analysis. This can be helpful for troubleshooting
purposes.
Switch > Port Mirroring
If this feature is enabled, Port 1 will only be able to
communicate with the source port and monitor the source
port’s traffic. Port 1 will not be able to communicate with
any other port while port mirroring is in effect.
Port Mirroring Setting
Type
To use port mirroring, select the direction in which
to monitor traffic:
Montor Egress
,
Montor Ingress
, or
Montor Both
. To disable port mirroring, keep the default
setting,
Dsabled
.
Source Port
If you have enabled port mirroring, select
the port whose packets will be duplicated to Port 1:
Port
(default),
Port
,
Port
,
Port 5
, or
Wreless
.

Switch > VLAN
The
VLAN
screen allows you to enable VLANs and select
the type of VLANs to be used on the switch.
Switch > VLAN
A VLAN is a group of ports that can be located anywhere
in a network, but communicate as if they are on the
same physical segment. VLANs help to simplify network
management by letting you move a device to a new VLAN
without changing any physical connections. VLANs can
be easily organized to reflect departmental groups (such
as Marketing or R&D), usage groups (such as e-mail), or
multicast groups (used for multimedia applications such
as videoconferencing).
Global VLAN Settng
To disable the VLAN feature, keep
the default setting,
Dsabled
. Otherwise select the type
of VLAN to be used on the switch, either
Port Based
or
80.Q
, then click
Apply Global Settng
.
Port Based
The switch uses port-based VLAN
mapping to limit traffic between the ports.
80.Q
The switch uses 802.1Q-based VLAN to
configure VLAN membership for all ports.
