Substitua o interruptor da espinha do nexo 9236C - vEPC
Índice
Introdução
Este documento descreve as etapas exigidas a fim substituir um interruptor defeituoso da espinha (nexo 9236C) em um Ultra-M setup que a rede virtual de StarOS dos anfitriões funciona (VNFs).
Informações de Apoio
Ultra-M é uma solução móvel virtualizada pré-embalada e validada do núcleo do pacote projetada simplificar o desenvolvimento de VNFs. Os server que são parte da instalação de Ultra-M são conectados a três tipos diferentes de Switches:
- Catalyst Switch
- Interruptor da folha
- Interruptor da espinha
A topologia de rede de um Ultra-M setup:
Este documento é pretendido para os Ciscos personnel que são familiares com a instalação de Cisco Ultra-M e as operações do Catalyst Switch.

Comute o procedimento de substituição
1. Instale o interruptor novo na cremalheira e conecte os cabos ao interruptor como notável. As etapas para a instalação do interruptor podem ser encontradas neste link: Guia de instalação de hardware do switch de modo do nexo 236C NX-OS da espinha
2. Verifique a versão de software do interruptor da espinha do nexo e promova-a/downgrade à versão de software conforme o link dado aqui: O upgrade de software e o Downgrade do 9000 Series NX-OS do nexo de Cisco guiam, liberam 7.x
3. Transfira o backup de configuração ao interruptor novo e copie essa configuração à partida-configuração
