Advanced—LACP Configuration

The LACP Configuration screen lets you set the LACP system priority, which specifies the

device’s link aggregation priority relative to the devices at the other ends of the links on which link

aggregation is enabled. To configure LACP:

1.

Select Switching > LAG > Advanced > LACP Configuration. A screen similar to the

following displays.

The LACP System Setting field is the only configurable field in this screen:

•

LACP System Setting

. LACP Port priority ranges from 0 to 65536. A higher value

indicates a lower priority. The default value is randomly selected.

2.

Click

Apply

to confirm any settings changes.

Advanced—LACP Port Configuration

The LACP Port Configuration screen, which is also referred to as the LACP Port Priority screen,

lets you set the LACP port priority and time-out value:

1.

Select Switching > LAG > Advanced > LACP Port Configuration. A screen similar to the

following displays.

You can make changes to the LACP port priority settings for an individual port, for a group of

ports, or for all ports simultaneously:

•

To change the LACP port priority settings for an individual port, select the check box to

the left of its port number, and then select the LACP port priority settings.

•

To change the LACP port priority settings for a group of ports, select the check boxes to

the left of their port numbers, and then select the LACP port priority settings.

•

To change the LACP port priority settings for all ports simultaneously, select the check

box at the top of the column of check boxes, and then select the LACP port priority

settings.

The following information about the LACP priority for a port is displayed. Both the LACP

Priority and Timeout fields are configurable.

•

Port

. Shows the port number.

•

LACP Priority

. Specifies the port priority value in a range from 1 to 65335.

VLAN

A virtual local area network (VLAN) is a way to electronically separate ports on the same switch

(from a single broadcast domain) into separate broadcast domains so that broadcast packets are not

sent to all the ports on a single switch. When you use a VLAN, users can be grouped by logical

function instead of physical location. The GS108T Smart Switch supports IEEE 802.1Q VLANs

and port-based VLANs, but not combination of both:

•

IEEE 802.1Q VLANs

The settings on the IEEE 802.1Q VLAN screen control the VLAN membership of each port

for transmitting packets. Also, these settings determine if transmitted packets from each port

are tagged with the VLAN ID and other information. The switch supports 64 tag-based

VLANs.

By default, every port is a member of VLAN 1, and so they have a port VLAN ID (PVID)

of 1.

•

Port-based VLANs

Single or multiple ports are grouped into a smaller virtual network, which is independent of

the other ports. The switch supports 8 port-based VLANs. Any user-assigned VLAN cannot

have member ports that belong to different port groups.

Basic—VLAN Configuration

The Basic VLAN Configuration screen lets you select the VLAN type and create VLANs. You

can select to create either IEEE 802.1Q VLANs or port-based VLANs. The screen functions

differently for IEEE 802.1Q VLANs than it does for port-based VLANs.

IEEE 802.1Q VLAN Configuration

To configure the IEEE 802.1Q VLAN type:

1.

Select Switching > VLAN > Basic > VLAN Configuration. A screen similar to the following

displays.

2.

Select the

IEEE 802.1Q

radio button to specify the IEEE 802.1Q VLAN type.

3.

The Warning screen displays. Click

OK

.

The following information about the VLAN configuration is displayed. Both the VLAN ID

and VLAN Name fields are configurable:

•

VLAN ID

. Specifies a VLAN ID from 1 to 4094.

•

VLAN Name

. Specifies the optional VLAN description.

4.

Perform one of the following actions:

To add a VLAN:

a.

Enter a number in the

VLAN ID

field.

b.

Enter a name in the

VLAN Name

field.

c.

Click

Add

.

To delete a VLAN:

a.

Select the check box to the left of the VLAN ID that you want to remove.

b.

Click

Delete

.
