I have recently found myself supporting a multi-site setup including a Cisco UC560, a 540, and a 520, and have been muddling my way through the adminstration so far.
However, I am sure there is a wealth of knowledge that I am missing out on, and would like to fill in some gaps in my skillset.
I was wondering if anyone could suggest any helpful and up to date books, training resources or courses that would assist me in maintaining the system. I am not currently pursuing certification or interested in exam-cram/brain-dump type material.
I am currently using a combination of the web-based Cisco Unity Express v7.1 web interface, and Cisco Configuration Assistant to maintain the servers. I am familiar with command-line router/switch configuration, so I would also like to learn the commands for this platform as well.
