Hi, I have the problem connecting quad ports(4 network ports with only one MAC address)NIC on cisco cat 4006 switch. Cat 4006 refuse to recognize the two network connection with same MAC address and it shows error state that" flapping occurs between ...port and ... port. So I cannot connect my firewall machine to Cat 4006 switch. Last time it works well with legacy 3Com switch. Pls advice me this difficulty. Regards, 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=20777&t=20777 -------------------------------------------------- FAQ, list archives, and subscription info: http://www.groupstudy.com/list/cisco.html Report misconduct and Nondisclosure violations to [EMAIL PROTECTED]
