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.
