1 排除故障 CGOS 的 CGR 1000 Bootflash 和系统镜像恢复 目录 简介背景信息先决条件要求使用的组件恢复步骤 简介 本文描述 troublshoot 步骤恢复 Bootflash 和系统镜像在 CGR 1000 背景信息 CGR1000 使用 Cisco Secure 对存储的数字 (SD) 卡存储器 kickstart 镜像 系统镜像 配置等等 在少见 occassions, SD 卡毁损 结果, kickstart 镜像和系统镜像毁损 这防止 CGR 启动 启动的顺序在给的图概述 在此条款的步骤概述是恢复从一损坏的 SD 卡存储器状态的 CGR 先决条件 1. 在本地 PC 安装的简单文件传输协议 (TFTP) 服务器 2. 设置 TFTP server 有 kickstart 镜像和系统镜像 要求 Cisco 建议您了解以下主题 : 1. 控制台电缆 2. CAT5 3. kickstart 镜像和系统镜像

2 使用的组件 本文限制对 CGOS 在 CGR 1120 和 CGR1240 的仅版本运行 本文档中的信息都是基于特定实验室环境中的设备编写的 本文档中使用的所有设备最初均采用原始 ( 默认 ) 配置 如果您使用的是真实网络, 请确保您已经了解所有命令的潜在影响 恢复步骤 1. 设置控制台电缆使用 PuTTY 2. 连接从本地 PC NIC 的 CAT5 电缆到 CGR ETH 2/2 这是在恢复进程时工作的唯一的接口 3. 设置本地 PC NIC 在相同子网作为 CGR 例如 ; PC 的网卡是 子网 对于 CGR 将是 子网 在 PuTTY 会话上, 您看到 : "loader>" 0xd version=0x , datecode=0xc080d17 CPLD version 0x14 Reset Reason = 0(0) Scratch pad test passed!!!
