Configuring Trunk Groups and Dynamic Link Aggregation

Trunk Group Load Sharing
When you configure a trunk group, you specify whether the trunk group is a “switch” trunk group or a “server” trunk
group:
• Switch trunk group – Use this type of trunk group to connect one HP Routing Switch to another HP Routing
Switch.
• Server trunk group – Use this type of trunk group to connect an HP Routing Switch to a file server or single
host device.
The HP device load shares across the ports in the trunk group. The method used for the load sharing depends on
the following:
• Traffic type – Layer 2 or Layer 3
• Trunk type – Switch or server
• For certain traffic, port type on which the traffic enters the HP device (Gigabit or 10/100)
NOTE: The port type applies only to Layer 2 traffic on a server trunk group configured on a Chassis device.
Table 5.1 lists how HP devices load share traffic across the ports in a trunk group on a Chassis device.
NOTE: HP devices also perform IP load sharing. See the “Configuring IP Load Sharing“ section in the
“Configuring IP” chapter of the Advanced Configuration and Management Guide .
