SFP+ PORTS Models 6750 and 6750-P have two SFP+ compatible ports on the rear of the device. These require the user to provide an SFP or SFP+ fiber transceiver to allow connection to fiber networks. See Appendix 1: SFP+ Fiber Adapter Selection for more information on selecting a fiber transceiver.
SECURITY BACKGROUND INFORMATION On January 1, 2020, California will be the first state to enforce cybersecurity and IoT related legislation. Oregon, New York and Massachusetts are following suit. California’s law is Title 1.81.26 “Security of Connected Devices” and mandates that we equip our products with security features that are appropriate to the nature and function of the device. By law, this encompasses all products that are assigned Internet Protocol addresses which can connect to the Internet directly or indirectly.
INTRODUCING SECURITY DOMAINS To simplify the process of managing security on your network, Pathscape 3 introduces the concept of a “Security Domain”. Below we will describe how to create a Security Domain and add or remove devices from it. In the Device tab of Pathscape 3 there is a new view that shows you the name of the device’s domain and a padlock icon showing its current state.
CREATING A SECURITY DOMAIN • After starting Pathscape, the online devices will populate the Device View. • Choose the Security Domain view from the Select View dropdown • Each device running V5 firmware will have a Red “Unsecured” value in the Security Domain column. •...
Page 14
• Print the Recovery Key. • You may also click on the Recovery Key, Select All and Copy the key to the Clipboard and store it in a safe place. • Press Continue to add the devices to the Domain. The devices will have an amber padlock and their properties will be read-only.
• As security parameters are verified, the amber padlocks will turn green and the properties of those devices will be read/ writable. ADMINISTERING A DOMAIN To administer a domain, click on the Security menu and select Administration. This will bring up the Security Domain Admin Login window.
Page 16
Factory Default If you want to clear the security settings of a device and remove it from the domain, choose Factory Default. Only devices in the Security Domain shown in this dialog box will be available to be defaulted. For devices that you do not have a password for, you must have physical access to factory default them before you regain network configurability.
LOCAL SECURITY - USING VIA WITHOUT PATHSCAPE VIA12 switches have features that use unsecure protocols, like Art-Net Trap & Convert. You may not intend to use Pathscape, but “bad actors” could potentially access the switch and change the configuration. Therefore it is prudent to configure Local Security to protect your network if you want to use Art-Net Trap &...
RECOVERING A DOMAIN If you lose the Administrator password (or it was maliciously changed without your consent), you can recover the domain, retaining its configuration and set new passwords. • From the menu, choose Security > Recover Domain. • Type in the 20-digit Recovery Key and press Continue. •...
• From the menu choose Security > Administration and Change Passwords to set a new User password. RETAINING DEVICE SETTINGS FROM UNKNOWN DOMAINS There are times when you don’t know the password of a Security Domain, but you’d like to retain all its configuration. Without logging in to a Domain, all devices that appear with amber padlocks are read-only.
SOFTWARE (PATHSCAPE) CONFIGURATION Wherever possible, we recommend using a PC with Pathscape to configure your VIA switch(es). For in-depth information on using Pathscape, see the Pathscape manual. Pathscape is available for macOS and Windows from the Software section of our website: https://www.pathwayconnect.com/index.php/products/software/176-pathscape. Use the QR Code below to visit the download page.
DEVICE PROPERTIES The following fields are shown in the Device Property Panel in Pathscape. Some are editable, while others are read-only. NOTE: If all properties are read-only (greyed out and uneditable), make sure you are logged into the correct Security Domain. SECURITY PROPERTIES Property Description...
Page 22
Property Description Serial Number Factory-assigned, Pathway serial number. Read-only. Checking this will lock the local controls on the front panel of the device. Scrolling menus allow you to read properties, but changing properties is disallowed. There is a 30-second delay upon boot before the Front Panel Lockout takes Front Panel Lockout effect.
Page 23
NETWORK PROPERTIES Property Description IP Mode Determines how IP settings are obtained. Options are Disabled, Static and Dynamic. User-set Internet Protocol address (IPv4) for this switch. If VLANs are enabled, the IP IP Address address is applied by default to the Management VLAN ID#. User-set subnet mask.
Page 24
VLAN PROPERTIES To enable/disable VLANs, use VLAN Global Properties under the VLAN Config Tab. The below properties will appear read-only in the Properties Pane (greyed-out); these are only configurable via the VLAN Global Properties button, as shown above. Property Description Shows whether VLANs are Enabled or Disabled, globally, on your entire network.
Page 25
RING PROTECT PROPERTIES Property Description Ring Protect Mode Set function for Ring Protect Mode. Specifies the VLAN ID# used to determine the integrity of the ring. May not be used Ring Protect Control for any other traffic. Valid ID# is any ID outside the range set in VLAN setup. Default is VLAN VLAN 4095.
Page 26
ADVANCED PROPERTIES Property Description User ID Custom numeric identification for external databases. VIA12 [6750, 6750-P, 6752-P, 6754-P] - Manual REV 1.0 • June 2020...
ADVANCED CONFIGURATION VLAN CONFIGURATION As described above, use the VLAN Config tab in Pathscape to configure network VLANs. A VLAN (Virtual Local Area Network) is a group of ports on the switch (or switches) that are configured to pass traffic to one another, but not to ports on any other VLAN.
Page 28
VLAN GLOBAL PROPERTIES Plan your VLAN layout before attempting configuration. The creation of a map of the network, showing which devices and which ports to associate with a given VLAN, is strongly recommended prior to configuration. EXTREMELY IMPORTANT NOTE: When configuring one or multiple VIA switches using Pathway’s software- based configuration tools, be certain the port connected to your computer is on the same VLAN ID# as the management and is not on a tagged port.
Page 29
Once you have set up the number of VLANs you need, you may edit the names of any of the available VLANs by using the VLAN Names panel. Double-click on the VLAN Name, give it a name and then click the button to save changes.
Page 30
If the Management VLAN is accidentally set to a value outside the VLAN range, it may be necessary to use the Factory Default option to restore communication with the management processor and allow further configuration. See Factory Default section for instructions. The VLAN range and individual VLAN configuration must be done prior to activating the Ring Protect feature.
Page 31
IP Mode must be set to “Static” if the VIA is to act as a DHCP server. Only one DHCP server may be active on any given VLAN. Setting the IP Mode to “Dynamic” does NOT enable the DHCP server – see below. If the IP Mode is set to “Dynamic”...
Page 32
VLAN IGMP PROPERTIES When using multicast data packets, such as streaming ACN (sACN), bandwidth efficiency may be improved by using IGMP (Internet group management protocol) to enable multicast filtering. Property Description IGMP Snooping Enable/disable IGMP snooping – allows the switch to correctly filter multi-cast traffic IGMP Querier Enable/disable the IGMP querier –...
Page 33
RING PROTECT CONFIGURATION For Ring Protect mode to function, VLAN support must be enabled. Property Description Status of Ring Protect Mode. Disabled (default): Ring Protection feature is turned off Ring Protect Mode Master: Only one switch may be set as the Master. Transit: All other switches must be set as Transit.
Page 34
RAPID SPANNING TREE Property Description Rapid Spanning Tree Enable / Disable Rapid Spaning Tree Protocol (RSTP) The Rapid Spanning Tree algorithm detects and prevents network loops. Networks with loops will have very poor performance. The interaction between RSTP and the Ring Protect system may cause long network re-configuration times when the ring topology is changed.
Page 35
QUALITY OF SERVICE (QoS) Quality of Service determines the relative priority of different data packets, which in turn determines which packets should receive preferential routing from a VIA switch. QoS is often used for the distribution of video and audio signals, including the Dante®...
Page 36
FACTORY DEFAULT In the event of a loss of communication with the device (eg. Management VLAN accidentally set to a value outside the VLAN range), it is possible to reset the switch to factory settings. To factory default a switch, turn the encoder knob to the switch main menu, which is the default menu showing the switch’s name and IP address.
PORT PROPERTIES AND CONFIGURATION Port status and properties may be reviewed by expanding the device in the device tree, and clicking on the subdevice/port. The properties for that port will then be shown in the Properties Panel. The following fields are shown in the subdevice/port properties panel. Some are editable, while others are read-only. BASIC PROPERTIES Property Description...

LLDP PARTNER Link Layer Discovery Protocol (LLDP) is an industry-standard method for device announcement and reporting described in the IEEE 802.1AB standard. Any Ethernet-aware device may announce itself using LLDP, not just switches. This feature is particularly useful when using VLANs as you can tell which device is connected to a port, even if the port is not on the management VLAN.
VLAN PROPERTIES Property Description Untagged (default): Only data belonging to the port’s specified VLAN ID# will be transmitted. Typically set when connected to end equipment. VLAN Tagged Tagged/Uplink: All traffic on all VLANs will be transmitted. Typically set when connected to another switch. VLAN Assigns the selected port to the specified VLAN.

By default, Art-Net Universe 0-0 is ignored by the VIA and the packets discarded. When Alternate Art-Net Mapping is enabled, VIA switches will map Art-Net Universe 0-0 to sACN Universe 1. When Alternate Art-Net Mapping is disabled, Art- Net Universe 0-0 will be ignored by the VIA and Art-Net Universe 0-1 will be routed as sACN Universe 1. Property Description When enabled, Art-Net data packets with broadcast address destinations are trapped...
PoE PROPERTIES (NOT SHOWN ON VIA12 MODEL 6750) Property Description Enabled by default, this option allows the user to completely disable PoE on a given port. Any PoE allocation set with the following parameter will be ignored. Ports 1-12 only. The PoE class as reported by connected device.
PoE MAX ALLOCATION Allows you to set an upper limit to the power available to a connected device, such as a Pathport gateway or Vignette wall station. Use Max Allocation to ensure critical devices will have power. Also use Max Allocation to compensate for Class 0 device power allocation;...
UPGRADING DEVICE FIRMWARE Firmware upgrades may only be done using Pathscape. The most recently released firmware is bundled with the most recent version of Pathscape. To ensure you have the most up- to-date firmware available for upgrading, ensure you have downloaded the most recent version of Pathscape from the Pathway site, https://www.pathwayconnect.com.
FRONT PANEL UI AND MENU The VIA12 models 6750, 6750-P, 6752-P and 6754-P feature a front panel UI, consisting of an LCD and a rotary pushbutton encoder for navigating menus and selecting options. If configuring the switch via a PC and Pathscape is not possible or practical, it is still easy to do using the front panel UI. This section will show the menu structure and descriptions of menu options.
Some menus, such as Network Settings, require the user to scroll down to accept or discard any changes made. The <Back> option will always move the menu up one level. The current menu will time out after approximately 30 seconds. FRONT PANEL LOCKOUT If using Pathscape, it is possible to enable the option Front Panel Lockout, which disables the ability to make any changes to the switch from the front panel UI.

The IGMP Querier establishes a table of active multicast groups by querying connected devices about which multicast groups each device wishes to join. For example, a gateway will request the multicast groups associated with the sACN universes that the gateway is patched to. Each switch operating an IGMP Querier on a VLAN must have valid IP settings on that VLAN.

APPENDIX 1: SFP/SFP+ FIBER ADAPTER SELECTION The VIA Gigabit switches allow the end user to provide a fiber adaptor. The adaptors are typically referred to as an SFP (Small Form Pluggable transceiver) or mini-GBIC (gigabit interface converter). Pathway part number 6799 is an SFP 850nm Ethernet Optical Transceiver that is compatible with VIA12, VIA16 and VIA8, capable of 1Gbps.
APPENDIX 2: VIRTUAL LOCAL AREA NETWORK (VLAN) A VLAN (Virtual Local Area Network) is a group of ports on the switch (or switches) that are configured to pass traffic to one another, but not to ports on any other VLAN. When multiple VLANs are established, some ports on the switch may need to be configured specifically to pass all VLAN traffic, to ensure overall traffic is routed correctly.
APPENDIX 4: RING PROTECTION Ethernet wiring schemes are based on a ‘star’-wiring topology. Ring (or loop) data wiring – where the last device in a chain is wired back to the first device – is forbidden. Only one data path between any two devices is allowed. But star-wiring layouts are prone to single point failures.
APPENDIX 5: RAPID SPANNING TREE PROTOCOL The Rapid Spanning Tree Protocol (RSTP) is another technology to prevent network loops. EAPS (described above in Ring Protection) requires more setup, as it needs a dedicated master and multiple transit switches, but this allows it to function within a few DMX frames during fail-over.
APPENDIX 6: QoS SETTINGS Quality of Service priorities are determined by the Differentiated Services Code Point (DSCP) field contained in each data packet header. DSCP values may range from 1 to 64, and are mapped to four egress (output) queues. The egress queues are, in turn, numbered from 1 (Best Effort) to 4 (Highest Priority).
APPENDIX 7: ELECTRICAL AND COMPLIANCE INFORMATION ELECTRICAL INFORMATION MODEL 6750 • Power input: 100-240VAC, 50/60Hz • 0.3A Maximum current draw MODEL 6750-P • Power input: 100-240VAC, 50/60Hz • 1.3A Maximum current draw • Integrated PoE supply: 100W; Class 3 PoE (15.4W maximum per port) MODEL 6752-P, 6754-P •...
