what is this serial number b1:e5:bd:8f:2x:58:xx:27 in device certificate?

Hi, I saw the serial number of the device certificates looks like below.

  b1:e5:bd:8f:2x:58:xx:27

What is this serial number associated with the device? Seems it isn't a device interface mac address. 

can someone please advise? Thanks in advance!

    The serial number in a device certificate resembles a unique identifier that is part of the device identity information used for authentication within a device group. This serial number is one of the components that make up the x509 certificate installed on the device, along with other details such as the device name, host name, platform serial number, platform MAC address, certificate name, subjects, expiration date, and signature status. The serial number plays a crucial role in identifying and validating the certificate associated with a particular device in the trust domain.

    To obtain the serial number of a device certificate on a BIG-IP system, you can use the Configuration utility. First, log in to the Configuration utility and navigate to System > Certificate Management > Device Certificate Management > Device Certificate. From there, you can select the specific device certificate you are interested in. Once you have selected the certificate, you can view its properties, including the serial number. This information is helpful for various procedures and validations related to device certificates on the BIG-IP system.
