Chapter 2 NE- and CTM-Specific Details
2.2.5 Naming Conventions
2.2.4.4 Managed Element and Object Creation Event
You can use the CTM client to add new managed elements. If the name of the new element is incorrect,
an object creation event is generated with the incorrect name. Later, when CTM connects to the actual
NE, it retrieves the correct name. CTM generates an AVC event to notify the NMS of the correct name.
2.2.5 Naming Conventions
The following sections describe naming conventions for objects that CTM reports.
2.2.5.1 Multilayer Subnetwork
You define the name in the CTM client. If you do not specify a name, CTM assigns a default name.
2.2.5.2 Managed Element
The ME reports the name.
2.2.5.3 Physical Termination Point
The PTP name represents the position of the PTP with respect to the equipment. For example, port
number 4 on equipment in slot 15 is reported as /rack=1/shelf=1/slot=15/port=4.
For multishelf NEs, the rack and shelf number must be included in the PTP name. ONS 15454 MSTP
NEs support up to eight shelves per NE. The shelf ID identifies a specific shelf on the NE. The rack ID
remains 1 for all shelves.
This PTP naming convention is used to represent the front Ethernet ports for the ONS 15454 SONET
and ONS 15454 SDH ML-series cards. The back Ethernet ports are reported as floating termination
points (FTPs).
For class of service (CoS) data on data cards, the PTP name specifies the interface (POS, Fast Ethernet,
Gigabit Ethernet), direction (input/output), and CoS level (0 to 7).
For example, CoS data with a POS interface, input direction, and CoS level 3 for slot 1, port 1 is reported
as rack=1/shelf=1/slot=1/port=1:POS/Input/3.
Similarly, CoS data with a Fast Ethernet interface, output direction, and CoS level 5 for slot 1, port 1 is
reported as /rack=1/shelf=1/slot=1/port=1:FastEthernet/Output/5.
For the ONS 15600 SONET, the ASAP card on slot 3, port 1 on PPM 3 and PIM 2 is reported as
/rack=1/shelf=1/slot=3/sub_slot=2/ppm_holder=3/port=1.
For the ONS 15310 CL, ONS 15310 MA SONET, and ONS 15310 MA SDH, a port on PPM number 2
is reported as /rack=1/shelf=1/slot=2/ppm_holder=2/port=1.
For the ONS 15454 SONET and ONS 15454 SDH, a port on PPM number 2 is reported as
/rack=1/shelf=1/slot=2/ppm_holder=2/port=1.
For the ONS 15530 and ONS 15540, the PTP name represents the position of the PTP with respect to
the equipment. It also specifies the CLI name, since there can be more than one interface type with the
same physical position. Numbering for equipmentHolders and ports starts from 0 in the NE. However,
the TMF convention is to start numbering from 1 for equipmentHolders and ports. Therefore, CTM
translates PTP names.
