Datto Networking: Routers: VLAN Settings

Follow

Topic

This article describes how to configure the VLAN settings for a Datto router.

Environment

  • Datto Routers
  • Datto Network Manager

Description

A Virtual LAN (VLAN) is a logical grouping of devices in the same broadcast domain, allowing devices to communicate as if they were on the same LAN, even if they are not connected to the same switch.

The Datto D200 router supports up to 5 VLANs per device.

Procedure

Navigation

In Datto Network Manager's Navigation menu, click Routers, then select VLANs from the expanded options.

Configuration

The Router VLAN settings page contains a table displaying all VLANs associated with a router. The table includes the following information about the router's VLANs:

  • Name: Displays the VLAN name
  • Assigned VLAN port(s): Displays what ports are assigned and using a VLAN
  • Actions: Clicking the ellipsis icon displays a prompt to delete a VLAN

Adding a VLAN

1. Click the Add VLAN button.

2. VLAN ID: Enter a VLAN ID. If previously tagged traffic matches this ID, the port will accept it.

  • Valid VLAN IDs are integers between 2 and 4094
  • IDs 991 through 994 are permanently reserved for Datto Networking operations

3. Assign a port to the VLAN by selecting the checkbox next to the port number. If a port is assigned to another VLAN, you must unassign it first.

5. Select the Enable DHCP check box to enable and configure DHCP:

  • Enter IP addresses for a DHCP pool start and end. A DHCP pool requires a start IP address when setting both a DHCP pool end and a DHCP lease time
  • The DHCP lease time is the amount of time (in minutes) a device can use a DHCP-supplied address on the network. Enter a DHCP lease time with a minimum of 5 minutes and a maximum of 10080 minutes (7 days)

6. Select the Advanced DHCP Options checkbox to enable and configure the following options:

  • Option 6 (DNS server): Enter a DNS server IP address
  • Option 33 (Static route): Enter a destination and gateway IP address
  • Option 42 (Time server): Enter a time server IP address
  • Option 66 (TFTP server): Enter a TFTP server IP address, or a URL up to 250 characters
Configured option values are sent to DHCP clients when they renew their DHCP lease.

DHCP reservations

DHCP reservations let you reserve IP addresses in a DHCP pool for specific devices, ensuring that:

  • Only the intended device will have that IP address
  • The address will not be assigned to another device

To add a DHCP reservation:

  • MAC: Enter the device's MAC address
  • Device Name: Enter the device's name
  • IP: Enter an IP address that is part of a configured DHCP pool, and that you would like reserved for the device.
  • Add/Remove: Click Add to add the rule. Click Remove to remove an existing rule
