SECTION 10.6 M504 / M505N Distinctions
Abstract:
The M50x has a “Primary WAN MAC” located on the bottom of each modem. The gateway allocates WAN MAC
Addresses, for each interface, based upon incremental priority from the primary WAN MAC.
The priority, at initial IF scan, is as follows
Priority IF Notes
Primary ETHERNET +0 If Present.
Each subsequent VLAN is assigned +1 hex digit
Secondary PTM +0 If No ETH Present.
Initial VLAN is assigned +1 hex digit.
Each subsequent VLAN Assigned +1 Hex digit.
Tertiary ATM +0 If No ETH or PTM Present.
Initial VLAN is assigned +1 hex digit.
Each subsequent VLAN Assigned +1 Hex digit.
Examples:
