Figure 8.2.93-1: MAC address
The following flags are coded within Octet 5:
– Bit 1 – SOUR (Source): If this bit is set to "1", then the source MAC address value is provided.
– Bit 2 – DEST (Destination): If this bit is set to "1", then the destination MAC address value is provided.
– Bit 3 – USOU (Source): If this bit is set to "1", then the source MAC address value contains the lower value and Upper Source MAC address value contains the upper value of an MAC address range.
– Bit 4 – UDES (Destination): If this bit is set to "1", then the destination MAC address value contains the lower value and Upper Destination MAC address value contains the upper value of an MAC address range.- Bit 5 to 8: Spare, for future use and set to "0".
Octets "m to (m+5)" or "n to (n+5)" and "o to (o+5)" or "p to (p+5)", if present, shall contain an MAC address value (12-digit hexadecimal numbers).
