I hope somebody can help us. We recently bought some HP c7000 Blade Enclosures with 2 Cisco 3120x switches inside. On the blades we run Windows Server 2003 and 2008 and use teaming.
When a switch needs to be replaced after an hardware failure the new switch will be unconfigured placed back into the c7000 enclosure. The ports of the 3120x are not shut so the Windows servers will start transmit traffic through that ports. The problem is that the switches are not yet properly configured.
How can we solve this problem? Or do we need a test enclosure where we can shut the ports before putting back in the porduction enclosure?
In order for your 3120 switches to work with you servers you need to do NIC teaming on the server side and also build an etherchanned on the switch side with your 2 switches stacked together so when you lose one switch the other one take over the function and start forwarding packets.
Unfortunately not. If you don't stack them then teaming is not going to do any good. When you stack them you have NIC redundancy and also switch redundancy. We use 3110x with IBM chassis and it works well. Why don't want to stack them?
