z These ports can be configured only with the physical configuration such as speed
and duplex mode, QoS, and ACL. Other conflicting configurations, such as STP
cannot be configured.
z These ports must belong to VLAN 1.
After assigning a port to a service-loop group, you may configure it with other
non-conflicting settings, such as QoS.
If this group is performing load sharing, it continues to function in this way even after all
selected ports but one are removed to ensure ongoing service.
1.5 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 reference 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 Port Correlation Configuration.
