Try to narrow down the cause of the link flaps: 1) Force link speed settings 2) Change patch cords 3) Replace physical NIC 4) Try patching to another switch port 5) Check switch port speed settings Hth. -- @shankerbalan M: +91 98860 60539 | O: +91 (80) 67935867 shanker.ba...@shapeblue.com | www.shapeblue.com | Twitter:@shapeblue ShapeBlue Services India LLP, 22nd floor, Unit 2201A, World Trade Centre, Bangalore - 560 055 Need Enterprise Grade Support for Apache CloudStack?
