Optional Feature Licenses

The software features are listed in the following table are managed as feature licenses. Feature licenses are distributed in one of the following forms:

In Switch Engine software (standard software component)—You must purchase a license to use the feature.
Modular software package (XMOD file, so named because of its .xmod file extension)—You must request the XMOD file from your supplier and install it.

For feature license and installation instructions, see Installing a Modular Software Package in the user guide.

Note

Secure Shell 2 (SSH2) is not provided as a feature license. It is incorporated into the main software image and is not provided as an XMOD. However, SSH2 contains strong encryption algorithms that heighten the export controls required in the US and other countries. When downloading the software image, you are required to verify that you meet the export clearance requirements. For more information, see Software Upgrade and Boot Options in the user guide.

For more information on SSH2, see Using Secure Shell 2 in the user guide.
