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).

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
