SmartTRUNK Load Redistribution

SmartTRUNK Configuration Guide

Status Interval = 1 second

Redistribution Interval = 5 Status Intervals

then

1 * 5 = 5 seconds per Redistribution Interval.

Note

To avoid flows “bouncing” back and forth between ports, SLR uses the rule that
no moved flow can be returned to the port from which it was moved until at least
one Redistribution Interval has passed.

Creating an SLR Enabled SmartTRUNK

The following is an example of creating a SmartTRUNK that uses SLR:

1.

Create a SmartTRUNK (

st.4

) — the control protocol is irrelevant to this example:

2.

Assign ports

et.4.1

through

et.4.4

to the SmartTRUNK:

3.

Accept SLR’s defaults and enable SLR on the SmartTRUNK.

To show the SmartTRUNK SLR configuration on

st.4

, enter the following command from Enable mode:

rs(config)# smarttrunk create st.4 protocol no-protocol

rs(config)# smarttrunk add ports et.4.1-4 to st.4

rs(config)# smarttrunk set load-redistribution-params st.4 enable

rs# smarttrunk show load-redistribution-params st.4 configuration

st.4 configuration:
