group. At present, you may specify to redirect four types of services, IPv6 (IPv6
unicast), IPv6mc (IPv6 multicast), tunnel, and MPLS.

Currently, the the Switch 4800G support to redirect tunnel services only.
After creating a service-loop group, assign ports that support its service type to the
group considering the following:
■ 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.
■ 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.
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 “Configuring a Port Group” on
page 150.
