This read-create integer sets the user-specified attribute flags, or administrative-group colors, for this interface, used in conjunction with csMplsPathInclude and csMplsPathExclude to steer path computation. It lets an administrator tag a link with specific characteristics, such as 'trusted' or 'high-bandwidth,' that tunnels can then require or avoid. An operator tagging all links within a secure data-center backbone with a shared color via csMplsInterfaceAttribFlags could then use csMplsPathInclude on sensitive tunnels to force them to stay entirely within that backbone.
