z 

The maximum total number of load-sharing aggregation groups and load-sharing service loopback 

groups supported on an S7900E series Ethernet switch is 128. For more information about 

aggregation groups, see Link Aggregation Configuration in the Access Volume. 

z 

You can change the service type of an existing service loopback group. For the change to be 

successful, you must ensure that the service group has not been referenced; the attributes of all 

member ports (if any) are not conflicting with the target service type; and no service loopback group 

has been created for the target service type, because only one service loopback group is allowed 

for a service type.  

z 

You can remove any service loopback group except the referenced ones.

Ports of Device A support the tunnel service. Assign GigabitEthernet 2/0/1 through GigabitEthernet 

2/0/3 to a service loopback group to increase bandwidth and achieve load sharing.  

# Create service loopback group 1, and specify the service type as Tunnel (unicast tunnel service).
