Configuring Shared DHCP Pools

Aruba Central allows you to configure shared DHCP Dynamic Host Configuration Protocol. A network protocol that enables a server to automatically assign an IP address to an IP-enabled device from a defined range of numbers configured for a given network.  pools in the Network Services > IP Address Manager page in a Global dashboard. The DHCP server maintains a pool of IP addresses and allocates an address to a DHCP-enabled client when it connects to the network. As the IP addresses are dynamic, the IP addresses that are no longer in use are automatically returned to the pool for reallocation.

You can add a maximum number of 20 pools including both system IP pools and DHCP shared pools.

The Shared DHCP Pools table displays the following information:

  • Pool Name—Name of the IP pool.
  • IP Range—Displays the IP range.
  • Hosts per DHCP VLAN—Displays the number of hosts per pool.
