Specifying a Site Using WAE devices (WAAS Data Sources)
For WAAS traffic, you can define a site associated with a WAE device without specifying the site's
subnets. Simply select all of the WAAS data sources coming from the WAE device(s) serving that site.
Site SanJose = WAE-SJ-Client, WAE-SJ-CltWAN, and WAE-SJ-Passthrough data sources.
Note Cisco recommends that you use subnets to specify WAAS-optimized sites. Use this method only if the
site's subnets cannot be determined.
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 nonoptimized traffic, it can be defined using a combination of WAAS data sources
and a subnet from a NetFlow Data Export (NDE) data source.
When you define a site using multiple data sources, be careful to make sure that those data sources do
not have duplicated traffic to avoid counting the site traffic statistics twice.
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. The data source and VLAN are secondary. In the following two
scenarios, the first receives the higher priority:
1.2.3.0/24 = Site D
WAE1-Client datasrc = Site E
The longest prefix has higher priority. It has the same data source/VLAN. In the following two scenarios,
the first receives 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
You can view a defined site.
Step 1 From the WAAS Central manager menu, choose Configure > Network Analysis Module > Basics >
Sites.
The Sites window appears. Defined sites are listed in the table.
