Specifying a Site Using Multiple Rules

You can define a site using a combination of multiple rules described above. For example, if a site has
both optimized and non-optimized traffic, it can be defined using a combination of WAAS data sources
and a subnet from a NDE data source.
When defining a site using multiple data sources, be careful to make sure that those data sources do not
have duplicated traffic to avoid double counting the site traffic statistics.

Resolving Ambiguity (Overlapping Site Definitions)

Conflicting rules are not allowed in site definitions. Of the following two scenarios, the second one is
not allowed.
1.2.3.0/24 from SPAN1 = SiteA
1.2.3.0/24 from SPAN1 = SiteB
Using a prefix is the preferred method. Data source and VLAN are secondary. In the following two
scenarios, the first would receive the higher priority.
1.2.3.0/24 = Site D
WAE1-Client datasrc = Site E
The longest prefix has higher priority (same data source/VLAN). In the following two scenarios, the first
would receive the higher priority.
1.2.3.0/24 from SPAN1 = Site A
1.2.0.0/16 from SPAN1 = Site C
The more refined (specific) rule has higher priority. In the following two scenarios, the first would
receive the higher priority.
1.2.3.0/24 from SPAN1 = Site A
1.2.3.0/24 (any datasrc) = Site D
Viewing Defined Sites
Step 1 Choose Setup > Network > Sites.
Step 2 The Sites screen appears. Defined sites will be listed in the table.
