Port Trunking Settings - D-Link DES-3528 - xStack Switch - Stackable Reference Manual

xStack® DES-3528/DES-3552 Series Layer 2 Stackable Fast Ethernet Managed Switch Web UI Reference Guide
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. On the port level,
the STP will use the port parameters of the Master Port in the calculation of port cost and in determining the state 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.
NOTE: If any ports within the trunk group become disconnected, packets intended for the disconnected
port will be load shared among the other linked ports of the link aggregation group.

Port Trunking Settings

On this page the user can configure the port trunk settings for the Switch.
To view the following window, click L2 Features > Link Aggregation > Port Trunking Settings, as shown below:
The fields that can be configured are described below:
Parameter Description
This is the traffic hash algorithm among the ports of the link aggregation group. Options to
Algorithm
choose from are MAC Source, MAC Destination, MAC Source Destination, IP Source, IP
Destination and IP Source Destination.
Unit Select the unit to configure.
Group ID (1-8) Select an ID number for the group, between 1 and 8.
Type This pull-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.
Choose the Master Port for the trunk group using the drop-down menu.
Master Port
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.
