Link Aggregation Group - D-Link DES-3226L Manual

DES-3226L Layer 2 Fast Ethernet Switch User's Guide
single link aggregation group. A link aggregation group may not cross an 8-port boundary,
starting with port 1 (a group may not contain ports 8 and 9, for example) and all of the ports in
the group must be members of the same VLAN. Further, the aggregated links must all be of
the same speed and should be configured as full duplex.
The configuration of the lowest numbered port in the group becomes the configuration for all
of the ports in the aggregation group. This port is called the Master Port of the group, 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.
