This identifies the source from which the currently running downloaded software was obtained, applicable to 6500 platforms. On a network where software can be pushed from multiple possible sources, such as a specific management station or a local flash bank, this tells an admin exactly where the currently active code actually came from, useful when confirming a software push originated from the intended distribution point rather than an old cached copy. For example, this reading a specific management-station address would confirm the currently running downloaded code was pushed from that particular server rather than loaded from a local backup source.
