Summary

The Network page contains information related to the device's networking. This chapter is an overview of the Network page in RUT300 devices.

If you're having trouble finding this page or some of the parameters described here on your device's WebUI, you should turn on "Advanced WebUI" mode. You can do that by clicking the "Advanced" button, located at the top of the WebUI.

LAN

This tab displays information about the device's local network(s). The figure below is an example of the Network window:

lan information
Name	LAN interface name
Address	IP address of the LAN interface
Netmask	Netmask of the LAN interface. In a sense, a netmask specifies the size of a network. In other words, it indicates which part of the IP address denotes the network, and which denotes the device
dhcp leases
Interface	Interface which leased the address
Hostname	Hostname of a LAN client
IP Address	IP address of a LAN client
MAC Address	MAC address of a LAN client
Leasetime Remaining	Remaining lease time for a DHCP client. Active DHCP lease holders will try to renew their DHCP leases after a half of the lease time passes.
Static Lease	This action will reserve currently assigned IP address for the device in Network -> Interfaces -> Static leases.

Similarly there is an IPv6 dedicated tab.

lan information
Name	LAN interface name
Address	IP address of the LAN interface
Delegated prefix	The delegated prefix is a smaller subnet given to a device to lease IPv6 addresses for its own DHCPv6 clients.
dhcp leases
Interface	Interface which leased the address
Hostname	Hostname of a LAN client
Address	IP address of a LAN client
Delegated prefix	The delegated prefix is a smaller subnet given to a device to lease IPv6 addresses for its own DHCPv6 clients.
DUID	DHCP unique identifier is used by DHCPv6 to identify device. Similar to MAC that is used by DHCPv4.
Leasetime Remaining	Remaining lease time for a DHCP client. Active DHCP lease holders will try to renew their DHCP leases after a half of the lease time passes.
Static Lease	This action will reserve currently assigned IP address for the device in Network -> Interfaces -> Static leases.

All active devices

This section displays the results of the scan.

field name	description
Hostname (Vendor)	Hostname of scanned device
IP Address	IP address of scanned device
MAC Address	MAC address of scanned device
Type	The type of connection
Interface	The interface the scanned device is connected
