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:
