Hi Sammy,
The Hub is primarily a forum for discussion of topics related to Extreme Networks' products, services, and concepts. We're glad to have you! However, it seems your question pertains to an issue you're experiencing with Cisco equipment. That said, I'd bet someone here in our community will have some tips to offer up. We're a helpful group with a very wide set of network knowledge.
EDIT: See ^, Patrick beat me to it!
