Hi all, I have the problem between apple machines and cisco catalyst switches. Last week, I replace my old 3Com switches to Cisco 3524 switches. Then most of my apple machines cannot access each other(cannot access appleshare). After I setup port speed and duplex mode on individual ports according to the apple machines NIC spec:, apple machines can access to PC server(MAC volume and e-mail). But some are still cannot see each others. I put back those apple machines to old 3Com switches and it works fine. All the apple machines have no zone settings. My network is flat network and no subnet. Do I need other special setting on my cisco switches for apple environment? Thanks for your advice, Moe. _________________________________________________________________ Get your FREE download of MSN Explorer at http://explorer.msn.com/intl.asp Message Posted at: http://www.groupstudy.com/form/read.php?f=7&i=20899&t=20899 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
