Overview

This article provides brief information on some third-party devices append additional bytes to the standard MAC address format of 6 bytes. This results in a non-standard MAC address of 9 bytes in length.

Standard MAC Address Format:

 

Extended MAC Address format (9 octets) :

0011 0101     0111 1011     0001 0010     0000 0000     0000 0000     0000 0000     0000 0000     0000 0000     0000 0000

 

Environment

  • All IPAM versions
  • 9-byte MAC devices

Detail

On import into IPAM, IPAM will read the MAC from right to left, truncating the standard MAC address by 3 bytes making the end device MAC invalid..

Example truncated Format:

 

Extended MAC Address format (9 octets) :

0000 0000     0000 0000     0000 0000     0000 0000     0000 0000     0000 0000
