For our example, we are configuring a HP 2810-48G switch. These commands should also work with the HP5400zl series.

Keep in mind, this is an example configuration. You site may:

Not require full remote access to your ESXi machine (no DRAC or iLO connection).
Use IPMI in place of Serial and Power controllers.

Network Overview

There are a number of different networks and hosts involved with a traditional Emulab setup.

For servers, we will have three machines hosted on a VMWare server:

Boss hosts the web interface, main testbed logic, and database.
Users exports filesystems and acts as a general login machine.
Router routes between the various networks.

We also have on the network:

HP 2810 Ethernet Switch Management Interface
Dell Remote Access Card for VMWare server
VMWare management interface
Power Controller (APC7902)
Serial Controller (IBM X330 + Obsolete Cyclades multi-port serial card)

Initial Ports

Port	Device
1	Uplink to Internet
2	Port for Dell Remote Access Card (DRAC) for the VMWare server (PowerEdge 2950)
3	Trunked port for the VMWare installation on the PowerEdge 2950
4	APC 7902 Power Controller
5	Serial Controller
6-9	Control Network ports for our testbed nodes

VLANS

VLAN	IP Range	Use
2002	Depends (our minibed is behind a NAT on 10.0.23.0/24)	Internet VLAN
2003	192.168.0.0/22	Control Network VLAN
2004	192.168.254.0/24	Control Hardware VLAN
2005	192.168.253.0/24	Users Network
2006	192.168.252.0/24	Boss Network
2007	192.168.224.0/20	Node IPMI Network

Switch Configuration

Here is the configuration from the HP Procurve 2810 at the ISI mini testbed. Please note that the max-vlans number can be, and should be, increased on switches that are capable of more (5400 series). We use a trunked interface (port 3) to hook into our VMWare ESXi server.

VMWare Network Setup

For the minibed at ISI, the VMWare ESXi server is on a single trunked port.

Boss VM

em0 is on INTERNET
em1 is on BOSS

Users VM

em0 is on INTERNET
em1 is on USERS

Router VM

em0 is on USERS
em1 is on BOSS
em2 is on CONTROL
em3 is on CONTROLHW

Setting vSwtich IGMP Version

I am not sure if this is necessary. ESXi defaults to IGMP version 3. We currently need IGMP version 2 support on our vSwitch. The enable this, follow the following steps in the vSphere client:

Click on the server
Click on the "Configuration Tab"
Click on "Advanced Settings" in the "Software" group
Select "Net" in the "Advanced Settings" dialog box tree
Set "Net.IGMPVersion" to "2"
