Before installing the module, review the requirements and specifications referred to in
this chapter concerning the following:
•
"Link Aggregation" on page 2‐1
•
"Module Placement in a Matrix E7 Chassis" on page 2‐2
•
"10BASE‐T Network" on page 2‐2
•
"100BASE‐TX Network" on page 2‐2
•
"1000BASE‐T Network" on page 2‐2

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
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.
In normal usage (and typical implementations) there is no need to enable/disable ports for
Link Aggregation. The default values will result in the maximum number of aggregations
possible. If the switch is placed in a configuration with its peers not running the protocol,
no aggregations will be formed and the modules will function normally (that is, Spanning
Tree will block redundant paths).
