Converting Port Number to Area ID
Except for the following cases, the area ID is equal to the port number:
• when you perform a port swap operation
• when you enable Extended Edge (also known as “displaced PID”) PID on the director
If you are using Extended Edge PID format (for example, the SilkWorm 48000 with configuration
option 5) and would like to map the output of the port number to the area ID, use the following formula
(for ports 0-127):
where:
a area
p port number
% modulus (or remainder)
