The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Web Services Management Agent (WSMA) Enhancements for Wireless Management feature allows you to reduce the reconnecting rates in an outage when device connections to the management server on wireless networks are disconnected unexpectedly. This feature also allows you to implement payload compression to optimize the bandwidth usage.
Your software release may not support all the features documented in this module. For the latest caveats and feature information, see Bug Search Tool and the release notes for your platform and software release. To find information about the features documented in this module, and to see a list of the releases in which each feature is supported, see the feature information table at the end of this module.

Only Web Services Management Agent (WSMA) EXEC response provides compression on demand.
WSMA must provide support to all transport protocols including Secure Shell (SSH), Transport Layer Security (TLS), HTTP, HTTPS, and other TCP protocols.
WSMA does not use the option to support gzip compression for HTTP.
Information About WSMA Enhancements for Wireless Management
In a network outage, thousands of devices on the same wireless network (for example, Smartgrids) try to reconnect to the Network Management Server (NMS) at the same time. However, only limited number of devices can reconnect successfully on the first reconnect and subsequent retries. This results in high billings of some devices that fail to reconnect.
Web Services Management Agent (WSMA) enhancements for wireless management allows you to reduce the reconnecting rates with smart back-off reconnect policy by enhancing the existing reconnect command.
The WSMA EXEC Agent enhancement allows you to optimize the payloads on wireless networks whenever possible to optimize bandwidth usage.
A new optional compression XML attribute in the WSMA EXEC request and WSMA EXEC response supports the new response payload compression feature. By default, there is no payload compression if the new compression XML attribute is not specified in the WSMA EXEC request.
