Viewing and Configuring a Switch

Follow

Scope

This article covers how to view and configure a switch. See here for information on setting one up.

Procedure

To view status and configure one or more switches that are already added and part of a Datto network, follow these steps:

1. Log into Datto Networking and go to the specific network that the switch is added to. 

2. Navigate to Manage > Switches.

3. Click on a specific switch's name. This will bring up a pop out pane. Note that you can scroll to the right to see more features (columns) within the ports grid and scroll up and down if you choose to see more ports (rows).

View status

Dynamic Port State Indicator
At the top left of the pane, you'll see a graphical representation of the switch ports from the last check in. Note that switches check in at five minute intervals, or whenever settings are changed, so states may take a few minutes to update after cable is plugged in or unplugged.

The color of the port is indicative of the state of the Ethernet link: 

  • Green: Enabled and connected
  • Grey: Enabled but not connected
  • Black: Disconnected

The color of the number is indicative of the state of the PoE:

  • White: PoE disabled
  • Orange: PoE enabled

Hovering over a port, will display information about connected devices and also allow you to enable or disable the link state and the PoE state, independently. 

  • If the port is directly connected to a Datto access point or switch in the same network, the device's name will be displayed and hyperlinked to the specific device's configuration pane.
  • If the device cannot be recognized to be a Datto device, a number will be displayed that indicates the total number of devices in the MAC forwarding table of the switch, filtered down to the specific port. Clicking on the hyperlinked number, brings up a list of MAC addresses for devices in the forwarding table. If available, the device's manufacturer information is also displayed.

You can also do an instant reset of both link and PoE, on a port that has either or both enabled.

MAC, IP, Power, etc.
View the MAC address of the switch, current IP address, management VLAN, POE budget and current PoE usage in the top right of the pane. Per port power draw is listed in the last column of the ports grid, under the PoE limit setting.

Configure
The pop out pane allows you to configure the following things:

Switch name and description
Set a name and description to help organize your switches. This can be done by clicking on the name in the blue banner and by editing the description field next to the switch image.

Per Port Configuration (Ports tab)
The following things can be configured from the ports grid, in the switch pane

Port Number Description
Port number matches the port number on the front panel of the device and the port number, in the image, in the switch pane. Port description May be used to note what device or network a specific port is connected to or the location of the device.

VLANs
There are three configuration options when it comes to configuring VLANs:

  1. Allowed VLANs: You can configure what VLANs are allowed through switch ports by adding them to the allowed VLANs list for specific ports.
  2. PVID: You can configure a Port VLAN ID (PVID) that will be used to tag any untagged packets that come into the port, with that specific VLAN ID. This is similar to the Native VLAN use case.
  3. Untagged VLANs: You can configure whether a packet that was tagged with a specific PVID should be untagged before it is sent out, or sent out with the tag by entering the specific VLAN ID in the Untagged VLANs (egress) column. For instance if you enter VLAN 500 in PVID column of port 1 and enter VLAN ID 500 in the untagged VLANs column of port 2, any untagged packet entering the port 1 will be tagged and forwarded on to VLAN 500 and if it leaves via port 2, it will be stripped of the VLAN tag, before it is sent out.

 Important Notes for VLANs:

  1. By default, all switches come configure with VLAN IDs 991-994 configured in the allowed VLANs list. This is to ensure that all ports come preconfigured to work with the seamless roaming function of Datto access points, when they are powered using our switches
  2. By default, all ports have VLAD ID 1 programmed into both PVID and Untagged VLAN columns. This is to ensure, regardless of which port is used for uplink, the switch is always manageable via Datto Networking. It is very important that you do NOT remove VLAN ID 1 (the management VLAN) from the PVID and untagged VLANs columns of the ports that are used for uplink, as this will result in the switch not checking into Datto anymore.

Port Mirroring

Link Aggregation 
Click here to read about how you can configure link aggregation.

Flow Control 
To enable flow control on a given port, simply check the box under the flow control column for that specific port and click save on the switch pane. Flow control is disabled by default.

Rate Limiting 
Enter a value between 0 and 1000 in Mbps in the Rx field (for receive/ ingress) and the Tx field (for transmit/ egress)  to put a limit on the bandwidth of a specific port. Values with up to 2 decimal places are allowed. Note that entering 0 or leaving the field blank, will set it to 1000 (1Gbps, no rate limiting).

Speed and Mode 
You can choose to set the speed and mode setting to 'Auto' and let the switch port negotiate this with the device it is connected to or set the speed/ mode manually. Note that, when you set it to Auto and the link is enabled, the negotiated speed is displayed below the drop down selector.

PoE Type
Used to specify whether PoE budget allocation should be done automatically or manually. 

  • Auto: The switch will prioritize power to the port that has a higher priority set. The manual limit cannot be set and will be ignored
  • Manual: The switch will limit power to this port to the value entered by the user

PoE Priority
Used to decide which ports to prioritize for PoE power, when the budget is reached. Can only be set when the 'PoE Type' is set to 'Auto'.

PoE Limit
Limits the maximum power that a port will provide. This is applied only when the 'PoE Type' is set to 'Manual'. 

Once you have changed the configuration, click "Save changes."

 

General switch Configuration (General tab)
The following things can be configured from the general tab, in the switch pane and will apply to the switch as a whole

IGMP Snooping 
You can choose to enable IGMP snooping globally on the switch and select which specific VLANs it should be applied to by clicking on the VLANs link. You can also pick a specific IGMP version to use - IGMPv2 or IGMPv3. IGMP snooping is off by default.

STP Root Bridge Info 
You can view the Spanning Tree Protocol root bridge info in this page too. Note that enabling or disabling STP is done from the Configure > Switches page, since it is typically enabled network wide on all switches. Note that the switches will have STP on by default (or on factory reset) and set to RSTP

Additional configuration

We will be enabling additional functionality in future releases. If you have additional configuration requirements, contact Datto support.
