Configuring DHCP on AOS-Switches

Dynamic Host Configuration Protocol (DHCPDynamic 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. ) is a protocol that enables a server to automatically assign IP addresses to hosts. The server uses the configured IP address pools or ranges to assign to hosts. You can configure multiple IP pools to not have duplicate or overlapping IP subnetsSubnet is the logical division of an IP network.. You can configure the IP address pools with various options to share with the hosts. For example, network address, subnet mask, DNSDomain Name System. A DNS server functions as a phone book for the intranet and Internet users. It converts human-readable computer host names into IP addresses and IP addresses into host names. It stores several records for a domain name such as an address 'A' record, name server (NS), and mail exchanger (MX) records. The Address 'A' record is the most important record that is stored in a DNS server, because it provides the required IP address for a network peripheral or element. server address.

To enable the DHCP service and to add DHCP pools on a switch, complete the following steps:

1. In the Network Operations app, select one of the following options:
   • To select a switch group in the filter:
     1. Set the filter to a group containing at least one switch.

        The dashboard context for the group is displayed.

     2. Under Manage, click Devices > Switches.
     3. Click the Config icon to view the switch configuration dashboard.
   • To select a switch in the filter:
     1. Set the filter to Global or a group containing at least one switch.
     2. Under Manage, click Devices > Switches.

        A list of switches is displayed in the List view.

     3. Click a switch under Device Name.

        The dashboard context for the switch is displayed.

     4. Under Manage, click Device.

        The tabs to configure the switch is displayed.

2. Click System > DHCP. The DHCP page is displayed.

3. To activate the DHCP service, move the Enable DHCP service toggle switch to the on position.

   The DHCP service can be enabled only if there is a valid DHCP pool.

4. To add a new DHCP pool, click +and configure the following parameters:

Name	Description	Value
Name	Name of the pool.	A string.
Network	A valid network IP address to assigned to the DHCP pool.	IPv4 address
Netmask	Netmask of the DHCP pool.	Subnet mask
Lease Time	The lease time for the DHCP pool in days-hours-minutes format.	You can set a maximum value of 365 days 23 hours and 59 minutes in the DD-HH-MM format.
Default Router	IP address of the default router in the subnet.	You can add up to 8 IP addresses.
DNS Server	Address of the DNS server. To add multiple DNS servers, click +.	You can add up to 8 DNS servers.
Netbios Server	Address of the Netbios server. The Netbios server address configuration is not required for Mobility Access Switches. To add multiple Netbios servers, click +.	You can add up to 8 Netbios servers. For Mobility Access Switches, an option called WINS Server is available.
IP Address Range	IP address range within the network and network mask combination. To add multiple IP address range, click +.	You can add up to 64 IP address range.
Exclude Address Range	IP address range to exclude. This field is available only for the Mobility Access Switches. To add multiple excluded address range, click +.	You can add up to 64 IP address range.
