O objetivo deste documento é ajudar a entender as etapas envolvidas na execução do ISSU em Catalyst 9000 e Catalyst 3850 Series Switches.
O In-Service Software Upgrade (ISSU) é um processo que atualiza uma imagem para outra em um dispositivo enquanto a rede continua a encaminhar pacotes. O ISSU ajuda os administradores de rede a evitar uma falha de rede ao executar uma atualização de software. As imagens são atualizadas no modo de instalação onde cada pacote é atualizado individualmente.
O ISSU é suportado em todos os Catalyst 3850 e Catalyst 9000 Series que suportam Stackwise-Virtual e também em chassis autônomos Catalyst 9400 / 9600 com supervisores duplos.
O StackWise Virtual (SVL) é composto por dois switches conectados para formar um switch virtual. O SVL suporta atualizações de software em serviço.
O ISSU suporta atualizações, downgrades e reversões.
Antes de continuar com ISSU, verifique se a plataforma realmente suporta ISSU. Verifique também se o ISSU é suportado entre o código atual e o código de destino. Detalhes do modo nas plataformas suportadas e matriz de compatibilidade ISSU podem ser encontrados aqui - Suporte ISSU entre versões
Note: O exemplo neste documento é baseado nos switches Cisco Catalyst 9500 configurados como Stackwise-Virtual. As etapas são aplicáveis ao chassi autônomo Cat9400 / Cat9600 com mecanismos de supervisão duplos e também aos dispositivos Catalyst 3850 / Catalyst 9000 configurados como Stackwise-Virtual.
C9500#show version | in IOS XE Cisco IOS XE Software, Version 16.09.02
O ISSU só é suportado se ambos os switches no Stackwise Virtual forem inicializados no modo INSTALL.
C9500#show ver | in INSTALL

Se o chassi for inicializado em um modo PACOTE, o ISSU não é suportado. Você verá erros como abaixo se tentar executar o ISSU quando os switches estiverem sendo executados no modo BUNDLE.

PASSO 2: Instalar_ativar
Ao executar esse comando, ocorre a seguinte sequência de eventos:
(i) Um temporizador de reversão é iniciado. Se o temporizador de reversão expirar, o sistema retorna ao mesmo estado antes do início do ISSU. O temporizador de reversão pode ser interrompido usando o comando install autorabort-timer stop. ISSU pode ser revertido usando o comando install abort issue.
(ii) O switch de standby é provisionado com o novo software e é recarregado com a nova versão de software. Em seguida, o switch ativo é provisionado com o novo software e é recarregado. O switch de standby com a nova imagem agora se torna o switch ativo e o switch ativo antigo se torna o standby.
No final desse procedimento, ambos os switches são executados com a nova imagem de software.
