TWAMP Test Session End and PM Retrieval
TheofficialendoftheactiveTWAMP testsessionphaseisdeclaredwhenthesendersendsa

followingexceptions:
•Thenextseqnomustbesettozero
•Thenumberofskiprangesmustbesetto
0.
•Themessagemustnotcontainanysessiondescriptorrecordsorskipranges.
TWAMPdoesnotusethefetch‐sessioncommandusedinOWAMP anddoesnotrelyupon

TWAMP Configuration on the NCTE
ConfiguringTWAMPontheNCTEinvolvesthefollowingsteps:
• OptionallychangingthemaximumnumberofsessionsallowedattheTWAMPresponder
•EnablingtheTWAMPresponder
– Optionallychangingthetestsessiontimeoutdefault
– Optionallychangingthecontrolsessiontimeoutdefault
– OptionallychangingthecontrolsessionTCPport
A1:1test‐sessiontocontrol‐sessionrelationship
issupported.OnceTWAMPisconfigured,it
ispossibletoviewitscurrentstatus.
Configuration Steps
ToconfigurethemaximumnumberofsessionsandtoenabletheTWAMPresponder,
completethefollowingsteps:
1. FromtheGlobalConfigurationprompt,type
probe responder twampandpressENTER
toaccesstheTWAMPResponderConfigurationprompt.
2. FromtheTWAMPResponderConfigurationprompt,type
max-sessions <1-n>,then
press
ENTER tosetthenumberofmaximumTWAMPsessionsallowedattheNCTE.
Thedefaultvalueis6.
3. FromtheTWAMPResponderConfigurationprompt,type
control source-port
<port_val>
, andpress ENTER tosetthesourcecontrolTCPporttoport_val.
Thedefaultvalueis862.
4. FromtheTWAMPResponderConfigurationprompt,type
test timeout <1-65535>,
thenpress
