WAAS Express on 2901 router


Hi friends

I want to deploy WAAS Express in 2901 router.

I bought the waas express license and install that. and upgrade the RAM to the maximum size (2.5 G)

after that I use the " waas enable" command under the WAN interface to enable the waas.

but after enabling the waas the license remain "not in use".


2901_Router#sho license detail WAAS_Express
Index: 1 Feature: WAAS_Express Version: 1.0
License Type: Permanent
License State: Active, Not in Use
License Count: Non-Counted
License Priority: Medium
Store Index: 1
Store Name: Primary License Storage


and in the "show waas status" output, there is no license.



 the IOS is recommended. what is the problem?

best regards

If using a sub-interface or logical-interface, i.e. Serial 0/2/0.1, Dialer1, Tunnel1, etc, configure waas enable under the sub-interface or logical-interface.

If the memory requirement is met and license is valid, the command will be accepted and a log message is generated to indicate that WAAS Express is enabled. Enter the command on other backup WAN interfaces that require WAAS Express to be enabled.

WAAS Express utilizes Cisco Classification Policy Language (C3PL) similar to those used by features like QoS and zoned-based firewall. The first time the WAAS Express is enabled, the default policy map, class maps, and parameter map will be generated. The default policy map and parameter maps are named waas_global. The WAAS Express-related policy map, class map, and parameter map are of type waas.

Use the command show waas status to show the interfaces that have WAAS Express turned on, along with license type, maximum number of flows supported by the platform, and total active and optimized connections
