LAG Implementation in the W310

This section describes the implementation of the LAG feature in the W310.
With the W310, you can aggregate the following to form a maximum of four (4) LAGs per
W310:
• the two GBIC ports to form a LAG,
• the bandwidth of three (3) groups of up to eight (8) 10/100BaseT ports in a LAG
The relationship between the W310 Port Numbers and the LAG logical Port Number that
will be assigned to each LAG is depicted below.

Port Redundancy

Port redundancy involves the duplication of devices, services, or connections, so that, in the
event of a failure, the redundant device, service, or connection can take over for the one that
failed.
In addition to Link Aggregation Groups—which comprise the basic redundancy mechanism
within the switch—the W310 offers an additional port redundancy scheme. To achieve port
redundancy, you can define a redundancy relationship between any two ports in a W310.
One port is defined as the primary port and the other as the secondary port. If the primary
port fails, the secondary port takes over. You can configure up to 8 pairs of ports (or LAGs)
per W310 for port redundancy. Each pair contains a primary and secondary port. You can
configure any type of port to be redundant to any other.

Port Redundancy Operation

The Port Redundancy feature supports up to eight (8) pairs of ports per W310. The redundant
or secondary port takes over when the primary port link is down. Port redundancy provides
for the following in the W310:
• Switchback from the secondary to primary port is allowed
• Switching time intervals can be set by the user
