Network Requirements
Before installing the module, review the requirements and specifications referred to in
this chapter concerning the following:
The network installation must meet the requirements to ensure satisfactory performance
of this equipment. Failure to do so will produce poor network performance.
Link Aggregation
Link Aggregation is a method of grouping multiple physical ports on a network device
into one logical link according to the IEEE 802.3ad‐2002 standard. Because Link
Aggregation is standards based, it allows for automatic configuration with manual
overrides (if applicable), and can operate on 10 Mbps, 100 Mbps, or 1000 Mbps Ethernet
full duplex ports. Thus the network administrator can combine a group of five 100 Mbps
ports into a logical link (trunk) that functions as a single 500 Mbps port. As long as the
DFE modules agree on which ports are in the trunk, there are no problems with looping,
and the Spanning Tree can treat this trunk as a single port.
