wo Nexus 7000s are named NX-7k-1 and NX-7k-2. The two VDCs in NX-7k-1 are named Cozy and Daisy, while the two VDCs in NX-7k-2 are named Annie and Guinness. These names reflect the names of my Newfoundland dogs. Since you didn't spend years living with these dogs learning their relationships to each other, perhaps a picture would help. Figure 18-12 shows the lay- out, the VDCs, and how they're all connected. Let's get started. I've already configured the VDCs on NX-7K-1, SO let's configure the Annie and Guinness VDCs on NX-7K-2. I'll start by defining the VDC with the vdc command. I have to specify a name and a VDC number. VDC1 is the system VDC, SO I have to start with 2: NX-7K-2(config)# vdc Annie id 2 Note: Creating VDC, one moment please Nexus Design Features 2010 May 27 00:05:57 NX-7K-2 %$ VDC-1 %$ %VDC_MGR-2-VDC_ONLINE: vdc 2 has come online Why don't we need to enable the VDC feature? I didn't write the code, but I speculate that the VDC feature is integral to the operating system. Even when you boot a 5010, which does not support multiple VDCs, it will report that it is booting VDC #1.

But a router or switch, even a virtual one, is pretty useless without any interfaces, SO let's allocate some. I'm going to allocate the first 24 ports from the 48-port blade in slot 3. You can allocate differently, but you must allocate interfaces in groups controlled by ASICs. As you'll see later in this chapter, those groups may seem odd. For now, let's keep it as simple as possible: NX-7K-2(config-vdc)# allocate interface Ethernet3/1-24 Moving ports will cause all config associated to them in source vdc to be removed. Are you sure you want to move the ports (y/n)? [yes] This warning is telling me that these ports will be removed from the system context. If I had configured those interfaces within this context, bad things will happen when I ya
