CONFIGURING PORTS

CONFIGURING LOAD SHARING

To set up the Summit to load share among ports, you must create a load-sharing group of ports. Load-sharing groups are defined according to the following rules:

•Ports on the switch are divided into groups of two or four.

•Ports in a load-sharing group must be contiguous.

•Follow the outlined boxes in Table 4-2through Table 4-6to determine the valid port combinations.

•The first port in the load-sharing group is configured to be the “master” logical port. This is the reference port used in configuration commands. It can be thought of as the logical port representing the entire port group.

Table 4-2, Table 4-3, Table 4-4, Table 4-5, and Table 4-6show the possible load-sharing port group combinations for the Summit1, Summit2, Summit3, Summit4 and Summit4/FX, and Summit48, respectively.
