Configuration procedure
The following only lists the configuration for switch A, and that on switch B is 
similar.
Manual aggregation
# Create aggregation group 1.
[SW8800] link-aggregation group 1 mode manual 
# Add Ethernet ports Ethernet2/1/1 to Ethernet2/1/3 into aggregation group 1.
[SW8800] interface ethernet2/1/1
 
[3Com-Ethernet2/1/1] port link-aggregation group 1
 
[3Com-Ethernet2/1/1] interface ethernet2/1/2
 
[3Com-Ethernet2/1/2] port link-aggregation group 1
 
[3Com-Ethernet2/1/2] interface ethernet2/1/3
 
[3Com-Ethernet2/1/3] port link-aggregation group 1
 
# When the aggregation group numbers are continuous, you can directly 
 
aggregate multiple ports into a group. The group number is allocated by the 
system.
 
[SW8800] link-aggregation ethernet2/1/1 to ethernet2/1/3 both 
Static LACP aggregation
# Create aggregation group 1.
[SW8800] link-aggregation group 1 mode static 
# Add Ethernet ports Ethernet2/1/1 to Ethernet2/1/3 into aggregation group 1.
