The BrightSign player implements the client identifier string as described in RFC4361. This is not necessarily the MAC address; it is a device unique identifier string that can be used to identify the device across many interfaces and protocols.
The DUID (aka Client Identifier string) is the string "BrightSign:" followed by the serial number printed on the player. Your DHCP server software may treat this as binary rather than a string, in which case you'll see see the byte values 42 72 69 67 etc.
You can use this spreadsheet to convert player serial number to DUID in various formats
The player is using a valid client identifier as defined in the referenced RFC; a router or DHCP server should be able to handle it properly.
Note that for zone policy, MAC address and Client Identifier may be separate fields as they are not guaranteed to be the same value.
For DHCP address reservations, if there is no specific DUID or Client Identifier field, enter the DUID string instead of the MAC address.
If you have a legacy DHCP server that requires the player to not send DUID or Client Identifier, the attached scripts will allow you to disable sending DUID on the player.
NOTE: BrightAuthor:connected/BSN.cloud setup that includes network configuration will reset the setting and the player will send DUID again. Device Provisioning, Network Recovery, and the Reprovision function in the remote DWS will reapply Device Setup so this potentially could cause a player to fall off the network if the DHCP server does not provide a lease when it sees the player with a DUID or Client Identifier instead of just its MAC address.
Follow these steps to apply the script to a player:
- Download the "DUID_autorun.brs" file attached to this article to disable DUID on the Ethernet (wired) port.
If the player is connecting to a wireless network with the wireless module, download the "DUID_Wireless_autorun.brs" file.
To disable DUID on all applicable network interfaces (wired, wireless, modem), download the "DUID_All_autorun.brs" file.
- Rename the file "autorun.brs".
- Copy it to the root folder (e.g. "SD:/") of an SD card that is formatted using FAT32 (Series 3 and newer players with firmware 6.2.94 or newer can also use exFAT).
- Power down the player.
- Insert the SD card into the player.
- Power on the player
- Wait a few moments, until the on-screen text instructs you to remove the SD card. Once the player is rebooted, it will no longer broadcast its DUID.
