MAC CONFIGURATION
The MAC Configuration field describes the current configuration of the
Media Access Control (MAC) and physical layers of the A and B ports.
The possible port configurations are as follows:
• Through-A - The flow of the primary ring is entering the MAC from
port A (primary ring in) and exiting through port B (primary ring out).
The secondary ring is isolated from the MAC with the flow entering
from port B (secondary ring in) and exiting through port A (secondary
ring out). In a normal ring state the HSIM-F6 MAC Configuration
should read “Through-A”.
