Help on LMI's
I am attempting to take the CCNA exam in a couple of weeks and I keep running in to different information. For example, are LMI's sent every 60 seconds or every 10 seconds? I am currently using Todd's Deluxe Edition 4th V. Todd says every 60, but my practice exams are saying every 10 seconds. Also, Todd's book seems to lack in regard to switch port security explanation/configuration and ip subnet zero explanation/configuration. I have cross referenced my studies with an older CISCO press book, "Cisco CCNA EXAM #604-607" by Wendell Odom... this has been very helpful, but I need more current study material. Moreover, could somebody direct me to a great source concerning ip subnet zero and switch port security configuration.
