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

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

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

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"
