Or is there no inter-VLAN communication? Indeed, are there VLANs? If you had a single 6500 and it failed, would there be a cost of thousands of dollars while a new one were shipped in and installed? From the size of the network, it would appear a LOT of data is flowing. How mission-critical is the core? ___________________________________ UPDATED Posting Guidelines: http://www.groupstudy.com/list/guide.html FAQ, list archives, and subscription info: http://www.groupstudy.com Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
