Thanks Greg for additional comments on draft-ietf-lime-yang-
connectionless-oam-methods-09. Similar to the change we proposed for draft-ietf-lime-yang-
connectionless-oam-12, We could set up-limit for statistics data, when up-limit gets reached, we can indicate overrun count happens.
Thanks!

主题: Re: [Lime] Last Call: <draft-ietf-lime-yang-connectionless-oam-methods-09. txt> (Retrieval Methods YANG Data Model for Connectionless Operations, Administration, and Maintenance(OAM) protocols) to Proposed Standard
Dear All,
please kindly consider my comments on draft-ietf-lime-yang-
connectionless-oam-methods presented below:
- rpc continuity-check:
- lacks ability to specify test packet generation interval;
- rpc uses session-packet-statistics and session-error-statistics where all packet counters are uint32. Because continuity-check may run forever, if count set to -1, counters may overrun. How the overrun reported in session-packet-statistics and session-error-statistics?
In summary, operation of continuity-check test in forever mode is underdefined.
Regards,
Greg

Abstract
This document presents a retrieval method YANG Data model for
connectionless OAM protocols. It provides technology-independent RPC
operations for connectionless OAM protocols. The retrieval methods
model presented here can be extended to include technology specific
details. This is leading to uniformity between OAM protocols and
support both nested OAM workflows (i.e., performing OAM functions at
different levels through a unified interface) and interacting OAM
workflows ( i.e., performing OAM functions at same levels through a
unified interface).

Hi Qin,
thank you for your expedient response.
I don't think that any additional configuration parameter to limit particular counter or all of them is required. I think that 4294967294 is natural, intuitive limit for uint32 counters. My questions are rather how overrun per counter is reported and what is the behavior of the counter itself upon it has been read to fill in response to an RPC.
Regards,
Greg
