HI Oliver,
Cisco WAAS uses several WAN optimization techniques, including TCP optimization called transport flow optimization (TFO), caching and compound compression known as data redundancy elimination (DRE), and persistent Lempel-Ziv (LZ) compression, to improve application performance over the WAN.
The amount of memory installed in a device dictates the level of performance and scalability the device can provide. As the memory capacity increases, the ability of a WAE to handle a larger number of connections or a larger addressable index space for compression also increases. Having larger amounts of memory also enables the WAE to run additional services, such as application acceleration or disk encryption, and positions the device to accept additional features that may be introduced in future software releases.
The NME-WAE family members all have fixed memory capacity and cannot be upgraded. From the WAE appliance family, the WAE-7326, 7341, and 7371 have fixed memory configurations. The WAE-512 and WAE-612, however, have configurable memory options, in that the WAE-512 can be configured with 1 GB or 2 GB of memory, and the WAE-612 can be configured with 2 GB or 4 GB of memory.
The amount of installed memory directly impacts what license is supported on each of the WAE models. The Transport license can be configured on any WAE model that has 512 MB of memory or more, which includes the entire product family. WAE models that have 1 GB of memory or more can be configured with the Enterprise license, which allows the WAE to operate some or all of the Enterprise license features. 1-GB WAE models configured with the Enterprise license (that is, NME-WAE-502 and WAE-512-1GB) can use disk encryption and perform application acceleration for CIFS as an edge device but not as a core device, but can terminate WAN optimized connections as a core device. WAE models with 2 GB or more (including the NME-WAE-522, WAE-512-2GB, WAE-612, WAE-7326, WAE-7341, and WAE-7371) can run the full suite of Enterprise license features as either a core or edge device.
Can you send me the complete output of the WAE # show accelerator ssl.
According to cisco the operational state should be Running and the configuration state should be Enabled.
If the
operational state =Shutdown
and the
configuration state=Enabled,
there likely is a licensing problem.
Also as the WAAS software comes with over 150 default application policies that determine the type of application traffic your WAAS system optimizes and accelerates.
The effective limit is also depends upon the Application Acceleration policies.
In most cases, you do not need to modify the acceleration TCP settings because your WAAS system automatically configures the acceleration TCP settings based on the hardware platform of the WAE device. WAAS automatically configures the settings only under the following circumstances:
•When you first install the WAE device in your network.
•When you enter the restore factory-default command on the device.
Kindly get back to me for furhter discussion.
