Configuring Distributed DHCP Scopes

Instant allows you to configure the 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.  address assignment for the branches connected to the corporate network through VPN Virtual Private Network. VPN enables secure access to a corporate network when located remotely. It enables a computer to send and receive data across shared or public networks as if it were directly connected to the private network, while benefiting from the functionality, security, and management policies of the private network. This is done by establishing a virtual point-to-point connection through the use of dedicated connections, encryption, or a combination of the two.. You can configure the range of 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.  IP addresses used in the branches and the number of client addresses allowed per branch. You can also specify the IP addresses that must be excluded from those assigned to clients, so that they are assigned statically.

On specifying the IP address ranges, a subnet Subnet is the logical division of an IP network. validation is performed to ensure that the specified ranges of IP address are in the same subnet Subnet is the logical division of an IP network. as the default router and subnet Subnet is the logical division of an IP network. mask. The configured IP range is divided into blocks based on the configured client count. For the Distributed, L3 mode, you can configure any discontiguous IP ranges. The configured IP range is divided into multiple IP subnets Subnet is the logical division of an IP network. that are sufficient to accommodate the configured client count. You can allocate multiple branch IDs per subnet Subnet is the logical division of an IP network.. The Instant AP generates a subnet Subnet is the logical division of an IP network. name from the DHCP Dynamic Host Configuration Protocol.

4. Click Next.
5. In the Branch Size tab, specify the number of clients to use per branch in the Clients per branch text box. The client count configured for a branch determines the use of IP addresses from the IP address range defined for a 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.  scope. For example, if 20 IP addresses are available in an IP address range configured for a 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.  scope and a client count of 9 is configured, only a few IP addresses (in this example, 9) from this range will be used and allocated to a branch. The Instant AP does not allow the administrators to assign the remaining IP addresses to another branch, although a lower value is configured for the client count.
6. Click Next. The Static IP tab is displayed.
7. In the Reserve first and Reserve last text boxes, specify the number of first and last IP addresses to reserve in the subnet Subnet is the logical division of an IP network..
8. Click Finish.
