Configuration Persistence Mode

Thedefaultstateofconfigurationpersistencemodeis“auto,”whichmeansthatwhenCLI

configurationcommandsareentered,orwhenaconfigurationfilestoredontheswitchis

executed,theconfigurationissavedtoNVRAMautomaticallyatthefollow ingintervals:

•Onastandaloneunit,theconfigurationischeckedeverytwominutes

andsavediftherehas

beenachange.

•Onastack,theconfigurationissavedacrossthestackevery30minutesiftherehasbeena

change.

IfyouwanttosavearunningconfigurationtoNVRAMmoreoftenthantheautomaticintervals,

executethesaveconfigcommandandwaitforthe

systemprompttoreturn.Aftertheprompt

returns,theconfigurationwillbepersistent.

Youcanchangethepersistencemodefrom“auto”to“manual”withthesetsnmppersistmode

command.Ifthepersistencemodeissetto“manual,”configurationcommandswillnotbe

automaticallywrittentoNVRAM.Althoughtheconfigurationcommandswill

activelymodifythe

runningconfiguration,theywillnotpersistacrossaresetunlessthesaveconfigcommandhas
