When I installed the ESX server, I used the native VLAN, but after you change the switch port from switchport mode access to switchport mode trunk, the ESX server needs to be configured to send specific VLAN traffic to the Service Console. Switchport trunk allowed vlan 10-20,100-102 spanning-tree port type edge trunk is the recommended spanning-tree type These commands give a description to the port and allow trunking of VLANs.

You need to configure the ports on the upstream switches in order to pass VLAN information to the ESX hosts’ uplink NICs I am assuming you have already installed and configured vCenter and the ESX cluster.Ĭisco recommends that you use 3 separate VLANs for Nexus traffic, I am using the following VLANs:ġ00 – Control – Control connectivity between Nexus 1000V VSM and VEMs (Non Routable)ġ01 – Management – ssh/telnet/scp to the cisco Nexux 1000v int mgmt0 (Routable)ġ02 – Packet – Internal connectivity between Nexus 1000v (Non Routable)Īnd I will also use VLAN 10 and 20 for VM traffic (10 for Production, 20 for Development)ġ) Install vSphere ( I assume you have done this step)Ģ) Configure Cisco Nexus 5020 Upstream Switchports VCenter installed as a virtual machine – 192.168.10.10 (on VLAN 10) VSphere 4 Update 1 Enterprise Plus (needed to use Cisco nexus1000v) In this guide the hardware used consists of:ģx HPProliant D元80 G6 with 2 4-port NICs. These will connect to Cisco Nexus 5020 Upstream Switches. The following guide describes the neccessary steps to install and configure a pair of cisco nexus 1000v switches to be used in a vSphere cluster.
