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”.
