Link aggregation
Configuration procedure
The following only lists the configuration for switch A, and that on switch B is
similar.
1 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
2 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.
[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
3 Dynamic LACP aggregation
# Enable LACP on Ethernet ports Ethernet2/1/1 to Ethernet2/1/3.
[SW8800] interface ethernet2/1/1
[3Com-Ethernet2/1/1] lacp enable
[3Com-Ethernet2/1/1] interface ethernet2/1/2
[3Com-Ethernet2/1/2] lacp enable
