POS modules allow direct connection to interfaces withinSONET.MIBs for POS modulesSeveral MIB objects allow you to collect errors for POS links. SONET equipment detects alarms anderror conditions from the three layers of the SONET protocol: section, line, and path. Other deviceson the network are notified of these events. For more information about these MIBs, refer to theUnified IP MIB Guide.Automatic protection switchingYou can manually force a protect interface to take over as a working interface by entering the apsforce command on the protect interface. This command is useful when you want to bring down aworking interface for maintenance purposes. For more information about how to configureAutomatic Protection Switching (APS), refer to the Brocade MLX Series and NetIron FamilyConfiguration Guide.62 Brocade MLX Series and Brocade NetIron XMR Diagnostic Guide53-1002426-02
