16.14. Reserving Public IP Addresses and VLANs for
Accounts
CloudPlatform provides you the ability to reserve a set of public IP addresses and VLANs exclusively
for an account. During zone creation, you can continue defining a set of VLANs and multiple public
IP ranges. This feature extends the functionality to enable you to dedicate a fixed set of VLANs and
guest IP addresses for a tenant.
Note that if an account has consumed all the VLANs and IPs dedicated to it, the account can acquire
two more resources from the system. CloudPlatform provides the root admin with two configuration
parameter to modify this default behavior—use.system.public.ips and use.system.guest.vlans. These
global parameters enable the root admin to disallow an account from acquiring public IPs and guest
VLANs from the system, if the account has dedicated resources and these dedicated resources have
all been consumed. Both these configurations are configurable at the account level.
This feature provides you the following capabilities:
• Reserve a VLAN range and public IP address range from an Advanced zone and assign it to an
account
• Disassociate a VLAN and public IP address range from an account
• View the number of public IP addresses allocated to an account
• Check whether the required range is available and is conforms to account limits.
The maximum IPs per account limit cannot be superseded.
