ptrmMacPosition
Module: DECHUB900-PTRM-MIB-V3-0
OID (symbolic): DECHUB900-PTRM-MIB-V3-0::ptrmMacPosition
OID (numeric): 1.3.6.1.4.1.36.2.18.11.3.4.1.4
Node type: OBJECT-TYPE
Type: INTEGER
Access: read-only
Description: This is the position of the Mac Chip. For modules like the DTMXM, the position of the MAC is settable via software. It can be either before port 1 (MacForward) or after its last port (MacBackward) This makes it easy to partition the ports on its own ring for an accurate ring map.
Modules that are end-stations and hence have no lobe ports may report Mac position as 1.
if the Mac is in MacForward position the ptrmMacPosition should be reported as 255.
For all other Ports, if the Mac is between port A and port B, the Mac postion should be reported as port A.
What is ptrmMacPosition?
Reports where this MAC chip sits relative to the lobe ports, used to build an accurate ring map; on modules like the DTMXM the position is software-settable as MacForward (reported as 255) or MacBackward, end-station modules with no lobe ports report position 1, and otherwise the value is the port label just before the MAC in the ring.
