Link Aggregation Port Group 75
Link Aggregation Port
Group
As mentioned earlier, in a manual or static aggregation group, a port can be
selected only when its configuration is the same as that of the master port in
terms of duplex/speed pair, link state, and other basic configurations. Their
configuration consistency requires administrative maintenance, which is
troublesome after you change some configuration.
To simplify configuration, port-groups are provided allowing you to configure for
all ports in individual groups at one time. One example of port-groups is
aggregation port group.
Upon creation or removal of a link aggregation group, an aggregation port-group
which cannot be administratively created or removed is automatically created or
removed. In addition, you can only assign/remove a member port to/from an
aggregation port-group by assigning/removing it from the corresponding link
aggregation group.
For more information about port-groups, refer to “Configuring a Port Group” on
page 58.

CAUTION: Ports in a link aggregation group with their configuration not
consistent with that of the master port are unselected ports. Unselected port may
affect the ongoing services. So if you want to modify the configuration of
aggregation ports, do it in aggregation port view.
