Tesira network ports and protocols
Biamp's Tesira products use a variety of network protocols to carry out their functions, and those protocols operate on a wide range of network port numbers. Network administrators often need to know the list of ports that a device might use to communicate over the network.
This article details all of the ports and protocols used by Tesira devices, as well as the ports and protocols used by PC's running Tesira software or Biamp Canvas software.
Tesira devices are not meant to be connected directly to the internet. The expectation is that enterprise network security best-practices are followed to provide upstream firewalls and routers between Tesira network ports and external public-facing networks.
See Tesira security best practices for a guide on securely deploying a Tesira system. For an overview of security terminology and practices, see Network Security.
System architecture
Definition of "system"
Biamp defines a Tesira “system” as one or more Tesira devices running a single configuration file. It is this concept of a system that allows the devices to share DSP resources and control data. Devices that are in the same system communicate with one another using various proprietary and non-proprietary protocols. A distributed system can be considered analogous to a single DSP hardware device, it is the sum of all of the connected components and will not function properly if components are missing.
IP addressing
Each device in a Tesira system must have an IP address.
Protocol
Tesira support Internet Protocol version 4 (IPv4). Internet Protocol version 6 (IPv6) is not supported.
Classes
Tesira supports all IPv4 address classes, including variable-length subnet masks.
Types
Tesira devices can be configured to use a static or DHCP IP address. The default setting is DHCP.
If DHCP is selected but no DHCP server is present on the network, a Tesira device will ‘autoconfigure’ with a Link-local IP address (169.254.xxx.xxx) to facilitate Zero-configuration networking.
Tesira Device Discovery
Tesira devices use a multicast protocol similar to mDNS-SD for device discovery and host resolution. The multicast IP range in use is (224.0.0.251-254). If Tesira devices on the same subnet report they cannot discover each other, the IGMP Snooping and/or IGMP Querier configuration of the control network may need to be investigated. A simple test may be disabling IGMP Snooping temporarily to see if Tesira device discovery resolves.
Multicast DNS
Tesira devices are configured by default to use Multicast DNS (mDNS) to resolve host names on the control network. Multicast DNS may be disabled via the Device Maintenance and Network Settings in Tesira Software.
802.1X
All Tesira Server-class devices support 802.1X on their control, AVB, and VoIP ports.
Tesira Forte X and Devio SCX support 802.1X
