APS Switching Modes
APS behavior and operation differs based on the switching mode configured for the APS group.
Several switching modes are supported in SR-OS.
The switching mode affects how the two directions of a link behave during failure scenarios and
how APS tx operates.
Unidirectional / Bidirectional configuration must be the same at both sides of the APS group. The
APS protocol (K byte messages) exchange switching mode information to ensure that both nodes
can detect a configuration mismatch.
•
If one end of an APS group is configured in a Unidirectional mode (Uni 1+1 Sig APS or
Uni 1+1 Sig+Data APS) then the other end must also be configured in a Unidirectional
mode (Uni 1+1 Sig+Data APS).
•
If one end of an APS group is configured in a Bidirectional mode then the other end must
also be configured in Bidirectional mode.
The support of switching modes depends on SC-APS / MC-APS, MDAs, port types and ecaps.
For a definitive description of the MDAs, port types, switching modes, bundles and
encapsulations supported with APS please see
