There are four different DNS SRV records that are supported in firmware.

  • pcoip-bootstrap (PCoIP Management Console 2.x and newer, Firmware 5.x and newer) - The firmware uses this DNS SRV record along with other records to complete the bootstrap process to discover and attach to the PCoIP Management Console.
    • The firmware performs this discovery attempt five minutes after the firmware acquires an IP address and every five minutes after that.
    • SRV record example: _pcoip-bootstrap._tcp.<domain name>
  • pcoip-tool (PCoIP Management Console 1.x record Firmware 4.x and older) - The firmware communicates to the MC named in the record.
    • The firmware performs this discovery attempt five minutes after the firmware acquires an IP address and every five minutes after that.
    • SRV record example: _pcoip-tool._tcp.<domain name>
  • pcoip-broker (Connection Management Server (CMS) record) - A message is sent to the Connection Management Server named in the record. It is up to that CMS to configure the zero client or PCoIP Remote Workstation Card to be brokered by that server.
    • The firmware only performs this discovery attempt once five minutes after the firmware acquires an IP address.
    • SRV record example: _pcoip-broker._tcp.<domain name>
  • pcoip-vcs (View Connection Server (VCS) record) If and only if the zero client firmware is configured for View Connection Server, View Connection Server + Auto-Logon, or View Connection Server + Kiosk then the zero client firmware changes the currently configured VCS address to the server named in the record.
    • The zero client firmware performs this discovery attempt five minutes after the firmware acquires an IP address and every five minutes after that.
    • SRV record example: _pcoip-vcs._tcp.<domain name>

For more information see the PCoIP Management Console Administrators' Guide

 

Notes:

  • Deployments that use a Management Console should not need the -broker and -vcs records
  • When configuring a DNS SRV record manually (static entry), ensure the preceding underscore is included. (automatic SRV creation prefixes the underscore)
  • The PCoIP Management Console discovery is always enabled while the CMS discovery is optional via the "Enable DNS SRV Discovery" in the Discovery page (the default is enabled).
  • The domain name will be obtained from the DHCP lease process when configured for DHCP or the Domain Name entered on the PCoIP Zero Client using a static Ip.
  • For creating third party SRV records, please refer to the third party documentation for the correct SRV record format.
