Configure GigaSMART Operation

Define a GigaSMART operation to enable SIP Flow Sampling. If combining Flow Sampling with Load Balancing GSOPs, make sure that you select both operations when creating the GigaSMART Operation.

(missing or bad snippet) Refer to Access GigaSMART from GigaVUE-FM for details.

To configure the GigaSMART Operation, do the following:

1.   (missing or bad snippet)GigaSMART Operations (GSOP).
2. Click New. On the GigaSMART Operations page, do the following:
