SmartTRUNK Configuration Guide SmartTRUNK Load Redistribution
To monitor SmartTRUNK SLR activity on st.4, enter the following command from Enable mode:
Notice that statistics displays the following values on a per-port basis:
•port name
•port capacity in bandwidth
•link utilization and its exponential moving average
•instances when water-marks have been exceeded
Also note that statistics reports how many flows have been redistributed since they were last cleared.
To see only a summary of the redistribution activities, enter smarttrunk show load-redistribution-params
st.4 summary while in Enable mode.
To clear the SLR statistics, use the following command in Enable mode:
6.4.3 Additional Controls Provided by SLR
SmartTRUNK Load Redistribution is primarily intended for use where large numbers of layer-2 flows are deployed
to carry traffic transparently. In this environment, SLR provides automatic load-balancing of flows on SmartTRUNKs
consisting of any number of ports. However, the smarttrunk set load-redistribution-params command
provides a number of parameters for enabling and tuning the behavior of SLR. The following sections describe two of
these parameters.
Note For a detailed description of all the load-redistribution-params
parameters, see the SmartTRUNK section in the Riverstone Network RS Switch
Router Command Line Interface Reference Manual.
