About Pathport VIA Ethernet Switches VIA™ Gigabit Ethernet switches are designed for live entertainment Ethernet systems, including audio and DMX-over-Ethernet networks. This manual covers models 6750 and 6750-P running firmware of 5.0 or higher. The VIA Ethernet Switch is intended specifically for signal routing between Pathport ®...
Panel Layouts Front Panel – model 6750/6750-P Main Display Messages Along with its soft label and IP address, the VIA may display optional messages. At present, the messages only report status of the Ring Protection feature, when enabled. Message Explanation Ring Protect Master: Init Switch configured as Master.
Rear Panel – model 6750 Rear Panel – model 6750-P Models 6750 and 6750-P require the user to provide an SFP (small-form pluggable) fiber adaptor to allow connection of the mini-GBIC ports to fiber optic networks. See Appendix 1 for recommendations on SFP adaptor selection. The IEC power plug may be connected to an AC power source with a voltage between 100 and 240VAC, either 50 or 60 Hz.
Base Configuration With the default screen shown on the LCD, press the encoder knob. The base configuration menu will be shown. Base Configuration Network Status Device Info/Status Turn the knob to scroll down the menu. The current menu item is highlighted in reverse video.
Network Setup Allows review and changes of the IP address, subnet mask and default gateway. These settings are the default values for the Management VLAN (typically VLAN 1), and will be used if VLANs are disabled. To edit these properties, push the knob again. Property Explanation Determines how IP settings will be obtained...
Device Info/Status Allows review of the following non-editable properties: Property Explanation Serial Number Factory-assigned, Pathway serial number MAC Address Factory-assigned media access control address Current operating firmware version. Firmware may be Firmware Version updated using software configuration tools OK: Ring is intact Init: Ring is initializing Ring Protect State Failed: Link between two ports has failed.
Advanced Settings Menu Item Menu Options Disabled (default) VLAN Support Enabled. Must be enabled to show VLAN Setup and Ring Protect feature Specifies lowest VLAN ID# available. VLAN Range Start: <x> Valid range: 1 to 4095. Default is 1. Specifies highest VLAN ID# available. VLAN Range End: <x>...
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 all switches are set to the same Management VLAN ID#.
VLAN Config/Status: Network Settings Property Explanation Determines how IP settings will be obtained IP Mode Disabled (default): No IP assigned. Static: IP settings manually set by user. Dynamic: IP settings will be obtained from a DHCP server. Manually sets IP address (IPv4) IP Address Turn knob to set each octet.
VLAN Config/Status: DHCP Server VIA switches can automatically assign IP addresses to connected devices, using a DHCP (dynamic host configuration protocol) server. Important: Only one DHCP server may be active on any given VLAN at one time. Running multiple DHCP servers will cause network reliability problems. The DHCP-hosting VIA switch must first be set to a static IP address on the desired VLAN, prior to enabling the DHCP server.
VLAN Config/Status: IGMP and Multicast Groups 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 Explanation Enable/disable IGMP snooping – allows the switch to IGMP Snooping correctly filter multi-cast traffic Enable/disable the IGMP querier –...
Ring Protect Setup This option will only be shown if VLAN support is enabled. Property Explanation Shows the current state of the switch. Press knob to change between: Ring Protect Mode: Disabled: Ring Protection feature is turned off Master: Only one switch may be set as the Master. Transit: All other switches must be set as Transit.
Rapid Spanning Tree Property Explanation Enable / Disable The Rapid Spanning Tree Protocol Rapid Spanning Tree (RSTP). Warning: Rapid Spanning Tree must be enabled on all switches to detect loops correctly. Network loops created through un-managed switches may not be detected correctly. Pathway's implementation of Rapid Spanning Tree Protocol should be inter-operable with other switch manufacturer's implementations.
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® audio standard, to meet the signal’s required timing constraints.
Utilities Allows the switch to be rebooted or factory-defaulted from the front panel. The action must be confirmed before being applied. After confirmation, the rotary knob will be locked out, and about 15 to 20 seconds will pass before the LCD changes. Factory default disables and defaults all VLANs, but does not change the switch’s IP settings.
Port Status and Configuration Menu Port Status may be reviewed by turning to rotary knob to reach the desired port. The LCD shows the following information. <Port Name> Port x : <link speed> VLAN <x> The port’s soft label is shown on the top line. By default, the label is the port number. Below is shown the port number and the link status or speed.
VLAN Type VLANs must be enabled from the Advanced Settings menu for this option to be shown. Property Explanation Untagged (Normal): Only data belonging to the port’s specified VLAN ID# will be transmitted. Typically connected to end equipment. VLAN Tagged (Uplink): All traffic on all VLANs will be transmitted. Typically connected to another switch.
Art-Net to sACN ‘Trap-and-Convert’ This option is only shown for ports set as Untagged (Normal). When enabled, Art-Net data packets with broadcast address destinations are trapped and converted to E1.31 sACN multicast packets, as the packets enter the port of the switch. The resulting sACN packets may then be filtered using the IGMP settings.
Except for Maximum Allocation, the PoE settings are not user-editable. The Maximum PoE Allocation allows you to set an upper limit to the power available to a connected device, such as a node. Use Maximum Allocation to ensure critical devices will have power.
Port Link Mode Allows review and editing of the port’s communication speed. Auto-negotiation allows the switch and the connected device to determine the fastest mutually supported connection speed. However, there are some situations where, due to poor cabling, interference or traffic congestion, ability to force the connection to a particular speed is desirable.

Appendix 1: SFP Fiber Adapter Selection The VIA Gigabit Switch models 6750 and 6750-P 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). Because of frequent catalog changes in the IT world, it is not possible to recommend part numbers from specific manufacturers.
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.
VLAN Guidelines Plan the VLAN layout first. The creation of a map of the network, showing which devices to associate with which VLAN, is strongly recommended prior to configuration. Generally speaking, ports connected to end devices will be configured as Normal/Untagged and given a VLAN ID#.
Appendix 3: 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.
Ring Protect State: Failed indicates the ring is broken. Communication is relying on the secondary port of the Master switch, and the overall network is now vulnerable. The fault should be located and corrected. Once the fault is corrected, the ring protect state will automatically revert to “Complete”.
Appendix 5: 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).
