1. Introduction
Fault Management for TRILL is defined in [TRILL-FM]. TRILL Fault
Management utilizes the [8021Q] CFM model and extends CFM with
technology specific details. Those technology specific extensions are
flow-entropy for multipath support, MEP addressing on TRILL
identifiers, and so on. The extensions are explained in detail in
[TRILL-FM].
Performance Management for TRILL is defined in [TRILL-PM]. TRILL
Performance Management utilizes the [Y.1731-2013/G.8013] and extends
it with Loss Measurement and Delay measurement.
Generic OAM Yang model [GENYANGGOAM] presents Generic Yang data model
for all OAM technologies.
In this document we extend the YANG model defined in [GENYANGGOAM]
and [TRILLOAMYANG] for TRILL OAM Performance management. Details are
provided in section 4 below.

4. YANG Extension
MEP Addressing is defined in Generic OAM YANG model[GENYANGGOAM]. In
this draft we augment MEP Configuration with Performance Management
configuration and statistics for Delay Measurement and Performance
Measurement.
For technology specific we are re-using identify defined in
[TRILLOAMYANG] model.
identity trill { base goam:technology-types; description
"trill type"; }
4.1 MEP Address
As defined in TRILL OAM Yang[TRILLOAMYANG] model. TRILL OAM Yang is
referenced.
4.1 MEP Configuration Extension
module: trill-oam-pm

Internet Draft TRILL PM YANG November 1, 2015
augment /goam:domains/goam:domain/goam:MAs/goam:MA/goam:MEP:
4.2 Flow Entropy
As defined in TRILL OAM Yang[TRILLOAMYANG] model.
4.3 Context-id
As defined in TRILL OAM Yang[TRILLOAMYANG] model.
4.4 Grouping Statements loss-measurement-configuration-group, groups
configuration objects for Frame Loss Measurement function defined in
[TRILL-PM].
loss-stats-group, groups statistics object for [TRILL-PM] Loss
measurement section.
measurement-timing-group, groups object used for proactive and on-
demand scheduling of PM measurement sessions.
delay-measurement-configuration-group, groups configuration objects
for Delay measurement function defined in [TRILL-PM]
delay-measurement-stats-group, groups statistics objects for a TRILL
Delay measurement sessions.
4.5 RPC definition
The rpc model facilitates issuing commands to a NETCONF server (in
this case to the device that needs to execute the OAM command) and
obtaining a response.
Grouping Statements loss-measurement-configuration-group,
measurement-timing-group, and delay-measurement-configuration-group
defines input extension for Delay and Loss measurement RPCs.
4.5.1 create-loss-measurement
RPC allows scheduling of one-way or two-way on-demand or proactive
performance monitoring loss measurement session.
4.5.2 abort-loss-measurement
RPC allow aborting of currently running or scheduled loss measurement
session.
Kumar, Deepak Expires May 4, 2016 [Page 6]
Internet Draft TRILL PM YANG November 1, 2015
4.5.3 create-delay-measurement
RPC allow scheduling of one-way or two-way on-demand or proactive
performance monitoring delay measurement session.
4.4.4 abort-delay-measurement RPC allow aborting of currently running or
scheduled delay measurement session.
5. TRILL PM data hierarchy The complete data hierarchy related to the
OAM YANG is presented below. The following notations are used within
the tree and carry the meaning as noted below. Each node is printed
as:
<status> <flags> <name> <opts> <type>
<status> is one of:
+ for current
x for deprecated
o for obsolete
<flags> is one of:
rw for configuration data
ro for non-configuration data
-x for rpcs
-n for notifications
<name> is the name of the node
If the node is augmented into the tree from another module, its
name is printed as <prefix>:<name>.
<opts> is one of:
? for an optional leaf or choice
! for a presence container
* for a leaf-list or list
[<keys>] for a list's keys
<type> is the name of the type for leafs and leaf-lists
