Managing Physical Networks

To provide virtual machines with access to a physical network, you must first add the network as a resource
in Lab Manager, and then assign the resource to one or more organizations.

Monitor IP Pool Usage for a Physical Network

Every virtual machine using a static IP addressing mode for a NIC connected to a physical network requires
an IP address from the IP pool of the physical network. This IP address stays with the virtual machine through
the various operations in Lab Manager. When you delete all instances of the virtual machine with this IP
address, Lab Manager releases the IP address to the IP pool. You can control the length of time Lab Manager
reserves released IP addresses before returning them to the IP pool. See "Configuring General Preferences" on
page 135.
If a network is running out of IP addresses, you can add more. See "Add or Remove IP Addresses to the IP Pool
of a Physical Network" on page 102 for information about adding IP addresses.
When you deploy a configuration in fenced mode (unless you use the Block In and Out option), Lab Manager
assigns external IP addresses from the physical network IP pool to virtual machines in the configuration.
You can, for example, use the external IP address to access a virtual machine from outside a fenced
configuration. When you undeploy this configuration, Lab Manager releases the external IP addresses.
For fenced configurations (except those using the Block In and Out option), Lab Manager creates a virtual
router that requires two IP addresses. The addresses for a virtual router return to the IP pool when you
undeploy the configuration.
To monitor an IP Pool
1 In the left pane, click Resources.
2 On the Physical Networks tab, move the pointer over a physical network name and select IP Pool.
The IP Pool page displays the network name, the IP pool, and the number of used and total IP addresses.
The table includes information about IP addresses from the pool that are in use. The Deallocate In column
indicates the amount of time remaining before an unused external IP address becomes available.

Add or Remove IP Addresses to the IP Pool of a Physical Network

Only system administrators can add IP addresses to a physical network.
To add or remove IP addresses to the IP pool of a physical network
1 In the left pane, click Resources.
2 On the Physical Networks tab, move the pointer over a physical network name and select Properties.
3 Click the General tab.
4 Type an IP address or IP address range in the Static IP Address Pool text box and click Add or select an
IP address or IP address range and click Remove.
5 Click Update.

Modify Physical Network Properties

By default, only system administrators can modify a physical network.
To modify a physical network
1 In the left pane, click Resources.
2 On the Physical Networks tab, move the pointer over a physical network name and select Properties.
