Hello
Please define me canonical and non-canonical format of mac address

thanks

Hello!

The difference between a canonical and noncanonical address is that in non-canonical the bits within each byte are transposed (swapped). In the canonical format of an Ethernet MAC address, bit 6 indicates whether the MAC address is universal (0) or local (1); bit 7 indicates whether the address is an individual (0) or group (1) address.

	Specify as shown
For an Ethernet port	Set bit 6=1 and bit 7=0 Set bits 0–5 and 8– 47 to the 46-bit local MAC address If an Ethernet LAN station is connected across a bridge to a non-Ethernet LAN, the destination MAC address in the VTAM PATH Definition statement may need to be coded differently.

Hello

Can you tell me what is binary of 12 in reverse order and how?

[unfraget]

if 6th bit is the U/L 0=universal 1=locally specified
and 7th bit indicate which address is type mcast/unicast

which bit indicates that is noncanonical format?
