Cabletron Systems SmartSwitch manual Monitoring SmartTRUNKs

Chapter 4: SmartTRUNK Configuration Guide

To add ports to a SmartTRUNK, enter the following command in Configure mode::

Create a SmartTRUNK that will be connected to a device that supports the DEC Hunt Group control protocol.

smarttrunk add ports <port list> to <smartrunk>

Specify Traffic Distribution Policy (Optional)

The default policy for distributing traffic across the ports in a SmartTRUNK is “round- robin,” where the SSR selects the port on a rotating basis. The other policy that can be chosen is “link-utilization,” where packets are sent to the least-used port in a SmartTRUNK. You can choose to specify the link-utilization policy for a particular SmartTRUNK, a list of SmartTRUNKs, or for all SmartTRUNKs on the SSR.

Specify traffic distribution policy.

smarttrunk set load-policy on <smartrunk list>all-smarttrunks round-robinlink- utilization
