Chapter 4
Configure the Network with Omada SDN Controller
VLAN
Enter a VLAN ID with the values between 1 and 4090. Each VLAN can be uniquely
identified by VLAN ID, which is transmitted and received as IEEE 802.1Q tag in an
Ethernet frame.
Gateway/Subnet
Enter the IP address and subnet mask in the CIDR format. The CIDR Notation here
includes the IP address and subnet mask of the default gateway. The summary of the
information that you entered will show up below in realtime.
Domain Name
Enter the domain name.
IGMP Snooping
Click the checkbox to monitor IGMP (Internet Group Management Protocol) traffic and
thereby manage multicast traffic.
DHCP Server
Click the checkbox to allow the Omada Gateway to serve as the DHCP server for this
network. A DHCP server assigns IP addresses, DNS server, default gateway, and other
parameters to all devices in the network. Uncheck the box if there is already a DHCP
server in the network.
DHCP Range
Enter the starting and ending IP addresses of the DHCP address pool in the fields
provided. For quick operation, click the
Update DHCP Range
beside the
Gateway/
Subnet
entry to get the IP address range populated automatically, and edit the range
according to your needs.
DNS Server
Select a method to configure the DNS server for the network.
Auto:
The DHCP server automatically assigns DNS server for devices in the network. It
uses the IP address specified in the
Gateway/Subnet
entry as the DNS server address.
Manual:
Specify DNS servers manually. Enter the IP address of a server in each DNS
server field.
Lease TIme
Specify how long a client can use the IP address assigned from this address pool.
Default Gateway
Enter the IP address of the default gateway.
Auto:
The DHCP server automatically assigns default gateway for devices in the
network. It uses the IP address specified in the Gateway/Subnet entry as the default
gateway address.
Manual:
Specify default gateway manually. Enter the IP address of the default gateway
in the field.
DHCP Omada
Controller
Enter the IP address of the Omada Controller. The DHCP server uses this IP address as
Option 138 in DHCP packets to tell clients where the controller is.
Legal DHCP Servers
Click the checkbox to specify legal DHCP servers for the network. With legal DHCP
servers configured, Omada Gateways and Switches ensure that clients get IP
addresses only from the DHCP servers specified here.
Option 60
Enter the value for DHCP Option 60. DHCP clients use this field to optionally identify
the vendor type and configuration of a DHCP client. Mostly it is used in the scenario
where the APs apply for different IP addresses from different servers according to the
needs.
Option 66
Enter the value for DHCP Option 66.
It specifies the TFTP server information and
supports a single TFTP server IP address.
