Information About the HTTP Server

An HTTP server, which can be turned off from the CLI to address security concerns, is embedded in the Virtual Supervisor Module (VSM).

If you want to turn off the HTTP server, see the following "Guidelines and Limitations".

Guidelines and Limitations

The HTTP server is enabled by default.

VUM will not install VEMs if the HTTP server is disabled. During VEM installation, VUM talks directly to the HTTP server to extract required module information from the VSM. To install VEMs, you must do one of the following:

Use VUM by enabling the HTTP server during VEM installation, and then disabling it after the VEMs are installed.

Install VEMs manually without using VUM.

The HTTP server must be enabled in order to get the Cisco Nexus 1000V XML plugin from the VSM.

Default Setting

The HTTP server is enabled by default.
