Power up the new Nexus switch and connect to the console port using a serial cable. The switch will take several minutes to boot. The initial configuration wizard starts automatically. Use the information you worked out with your team or with the customer to complete the wizard.
How many VDC can be configured in Nexus?
The maximum number of VDCs that can be configured per Nexus 7000 chassis is four; the default VDC (VDC 1) and three additional VDC(s).
What is the default STP on Nexus switch?
Cisco Nexus switches enable Spanning Tree Protocol (STP) by default on all interfaces in every VLAN. However, network engineers who work with medium-size to large-size data centers usually want to configure at least some STP settings, with the goal of influencing the choices made by STP.
Does Nexus 9k supports VDC?
The Nexus 9000 supports Application Centric Infrastructure (ACI) in contrast to the Nexus 7000 switches. However, the Cisco Nexus 9000 switches do not support the VDCs (Virtual Device Context) technology like the Nexus 7000 and the Nexus 9000 Series doesn’t support storage protocols, in contrast to the Nexus 7000.
How many VDCs can a Sup2 have?
four VDCs
To run FCoE, Sup2/2e is required. With Supervisor 1 you can have up to four VDCs and one Admin VDC, which requires 8 GB of RAM because you must upgrade to NX-OS 6.2. Supervisor engine 2 can have up to four VDCs and one Admin VDC.
How do I configure STP?
How to configure STP?
- STP configuration. Enter Global Configuration mode: switch# configure terminal.
- Root Guard configuration. The Root Guard feature is responsible for verifying if the port on which it was enabled is a designated port.
- STP configuration verification.
What is VDC in Nexus 9k?
Virtual Device Contexts Cisco NX-OS can segment operating system and hardware resources into virtual device contexts (VDCs) that emulate virtual devices. The Cisco Nexus 9000 Series switches currently do not support multiple VDCs. All switch resources are managed in the default VDC.
How do I manually configure a switch?
Steps to configure Cisco switch using CLI
- Step 1: Use an external emulator such as Telnet or a PuTTY to login to the switch.

- Step 2: Provide a hostname for the switch to function in a particular network environment.
- Switch(config)#hostname switch.
What is the default VDC?
Default VDC is used to create, Delete, and manages other VDC. Default VDC cannot be deleted. Via Default VDC we can allocate the Ports to Non-Default VDC. Default VDC can be replaced to Admin VDC from Cisco NX-OS 6.1.
What is vPC and VDC in Nexus?
Most Nexus-based data center designs today use the concept of Cisco® virtual device context (VDC), which allows the creation of separate control-plane domains in a single switch. From a forwarding perspective, vPC is deployed in the context of a VDC.
Which switch should be root bridge?
Every switch taking part in spanning tree has a bridge priority. The switch with the lowest priority becomes the root bridge. If there’s a tie, then the switch with the lowest bridge ID number wins. The ID number is typically derived from a MAC address on the switch.
What is root bridge in STP?
The root bridge of the spanning tree is the bridge with the smallest (lowest) bridge ID. Each bridge has a configurable priority number and a MAC address; the bridge ID is the concatenation of the bridge priority and the MAC address. For example, the ID of a bridge with priority 32768 and MAC 0200.0000.
