Dit document beschrijft de stappen voor het uitvoeren van een In-Service Software Upgrade (ISSU) op Catalyst 3850- en Catalyst 9000-serie switches.
In-Service Software Upgrade is een proces waarbij een image wordt geüpgraded naar een ander image op een apparaat terwijl het netwerk pakketten blijft doorsturen. ISSU helpt netwerkbeheerders een netwerkstoring te voorkomen wanneer ze een software-upgrade uitvoeren. De beelden worden geupgrade in de installatiemodus, waarbij elk pakket afzonderlijk wordt geüpgraded.
ISSU wordt ondersteund op alle Catalyst 3850 en Catalyst 9000 Series die stapelbare virtuele servers ondersteunen, alsook op Catalyst 9400/9600 stand-alone chassis met dubbele supervisors.
StackWise Virtual (SVL) bestaat uit twee switches die met elkaar verbonden zijn om één Virtual switch te vormen. SVL ondersteunt in-service software-upgrades.
Voordat u verder gaat met ISSU, controleer of het platform daadwerkelijk ISSU ondersteunt. Controleer ook of de ISSU tussen de huidige code en de doelcode wordt ondersteund. De modusdetails op de ondersteunde platforms en de ISSU-compatibiliteitsmatrix zijn hier te vinden:
ISSU-ondersteuning tussen releases
Opmerking: Het voorbeeld in dit document is gebaseerd op Cisco Catalyst 9500 switches die als stapelbare virtueel zijn geconfigureerd. De stappen zijn van toepassing op Cat9400 / Cat9600 stand-alone chassis met dubbele supervisor motoren en ook voor Catalyst 3850 / Catalyst 9000 apparaten geconfigureerd als stapelbare virtuele.
Om pakketverlies tijdens het proces te voorkomen, vereist ISSU redundantie in uw knooppunten naar zowel de actieve als stand-by apparaten. Aangezien herladen plaatsvindt en een overschakeling tussen hen is vereist om een hoge beschikbaarheid in uw netwerk te garanderen.

ISSU wordt alleen ondersteund als zowel de switches in Stackwise Virtual zijn opgestart in Install mode.

Als het chassis in de bundelmodus is opgestart, wordt ISSU niet ondersteund. U kunt dit soort fouten zien als u probeert ISSU uit te voeren wanneer de switches in de bundelmodus draaien.

Nadat alle vereisten zijn geverifieerd, kunt u doorgaan met de eigenlijke upgrade en een van de volgende methoden gebruiken:
Deze workflow omvat slechts één stap en helpt bij optimalisatie.
Opmerking: U kunt niet terugdraaien omdat de upgrade automatisch wordt uitgevoerd. Ga verder met 3 Stap Werkstroom als u terug wilt rollen.
