periods - see 'cLOC'.
* Fault Cause cPeriod is declared if a CCM PDU has been received with different
period - see 'cPeriod'.
Selecting 300f/sec or 100f/sec will configure HW based CCM (if possible).
Selecting other frame rates will configure SW based CCM. In case of enable of
Continuity Check and Loss Measurement both implemented on SW based CCM,
'Frame Rate' has to be the same.
APS Protocol:
Object Description
 Enable Automatic Protection Switching protocol information transportation based on
transmitting/receiving R-APS/L-APS PDU can be enabled/disabled. Must be
enabled to support ERPS/ELPS implementing APS. This is only valid with one
Peer MEP configured.
 Priority The priority to be inserted as PCP bits in TAG (if any).
 Cast Selection of APS PDU transmitted unicast or multi-cast. The unicast MAC will be
taken from the 'Unicast Peer MAC' configuration. Unicast is only valid for L-APS -
see 'Type'. The R-APS PDU is always transmitted with multi-cast MAC described
in G.8032.
 Type R-APS : APS PDU is transmitted as R-APS - this is for ERPS.
L-APS : APS PDU is transmitted as L-APS - this is for ELPS.
 Last Octet This is the last octet of the transmitted and expected RAPS multi-cast MAC. In
G.8031 (03/2010) a RAPS multi-cast MAC is defined as 01-19-A7-00-00-XX. In
current standard the value for this last octet is '01' and the usage of other values
is for further study.
