The SFP+ subcards and GE subcards of the S5500-EI switches do not support service loopback
groups.

Functions of Service Loopback Groups

To increase service redirecting throughput, you can bundle multiple service loopback ports into a logical
link, called a service loopback group. Similar to link aggregation, a service loopback group can increase
bandwidth and implement load sharing.
Service loopback groups fall into five types:
IPv6, supporting IPv6 unicast traffic
IPv6mc, supporting IPv6 multicast traffic
Tunnel, supporting unicast tunnel traffic
Multicast tunnel, supporting multicast tunnel traffic
MPLS, supporting MPLS traffic
Currently, the S5500-EI switches only support the tunnel service.

Port Configuration Prerequisites of Service Loopback Groups

Before assigning a port to a service loopback group, ensure that:
The port supports the services type or types of the service loopback group.
The port is configured with only physical configurations such as rate and duplex mode, QoS and
ACL configurations.
