DGS-3200 Series Layer 2 Managed Gigabit Ethernet Switch Web UI Reference Guide

100

The (optional) Gigabit ports can only belong to a single link aggregation group. All of the ports in the group must be members of

the same VLAN, and their STP status, static multicast, traffic control; traffic segmentation and 802.1p default priority

configurations must be identical. Port locking, port mirroring and 802.1X must not be enabled on the trunk group. Further, the

LACP aggregated links must all be of the same speed and should be configured as full duplex.

The Master Port of the group is to be configured by the user, and all configuration options, including the VLAN configuration that

can be applied to the Master Port, are applied to the entire link aggregation group.

Load balancing is automatically applied to the ports in the aggregated group, and a link failure within the group causes the

network traffic to be directed to the remaining links in the group.

The Spanning Tree Protocol will treat a link aggregation group as a single link, on the switch level. For STP, the path cost of the

link aggregation group is determined by the active port number of the link aggregation group. If two redundant link aggregation

groups are configured on the Switch, STP will block one entire group; in the same way STP will block a single port that has a

redundant link.

The following parameters can be configured or viewed:

Parameter Description

Algorithm Toggle between MAC Source Dest and IP Source Dest.

Group ID (1-12) Select an ID number for the group, between 1 and 5 for the DGS-3200-10, between 1 and 8

for the DGS-3200-16, and between 1 and 12 for the DGS-3200-24.

Type This drop-down menu allows users to select between Static and LACP (Link Aggregation

Control Protocol). LACP allows for the automatic detection of links in a Port Trunking Group.

Master Port

Choose the Master Port for the trunk group using the drop-down menu.

State Use the drop-down menu to toggle between Enabled and Disabled. This is used to turn a

port trunking group on or off. This is useful for diagnostics, to quickly isolate a bandwidth

intensive network device or to have an absolute backup aggregation group that is not under

automatic control.

Trap

Use the drop-down menu to enable or disable trap. When set to enable, Link Up and Link

Down notifications are enabled for this link aggregation group. When set to disable, Link Up

and Link Down notifications are disabled for link aggregation group. By default, the trap

status for a link aggregation group is disabled. This notification is generated when LACP

logical interface link up (the first member port link up) and link down (the last member port

link down).

Member Ports

Choose the members ports for the trunked group. Up to eight ports per group can be

assigned to a group.

Active Ports

Shows the ports that are currently forwarding packets.

Click the Apply button to accept the changes made. Click the Clear All button to clear out all the information entered. Click the

Add button to add a new entry based on the information entered.
