Hi All, I've been fighting a problem on campus where students laptops appear to be dropping their ip connection to the network sporadically. I'm hoping someone can shed some light on the situation. I think I've narrowed it down to the broadcast limiting in the Access Points. I was using the default threshold settings, and thinking I either need to dramatically up them or remove them altogether. The definition in the Avaya "documentation" (<insert your own joke here>) states: "If the maximum value of Broadcast or Multicast per second is exceeded, the Base Station will ignore all subsequent messages issued by the particular network device, or ignore all messages of that type." The default settings limit to 30 frames/sec for an address and 60 for a port (ethernet and wireless). So what I take this to mean is, if a mac address transmits more than 30 broadcasts/second (in our network, not unheard of), then it gets ignored. Now, this would seem to be what his happening. Except the problem is, the address getting blocked/ignored is the router address (caused by an arp storm perhaps). So my question is, once an address is ignored, what does it take to get the access point to allow that address to be heard again? Is there a time limit? How does this work exactly? Any info/insight would be greatly appreciated.
