引起崩溃的错误通常是由处理器硬件检测的,处理器硬件在 ROM 监视器中自动派生出特殊的错误处理代码。ROM 监视器可以识别错误,打印消息,保存故障信息并重新启动系统。 开始规则 有关文件规则的更多信息,请参阅 Cisco Technical Tips Conventions. 前提条件 本文没有任何特定的前提条件。 所使用组件 本文不限于任何特定的软硬件版本。 获得有关崩溃的信息 在路由器崩溃的情况下,最重要的工作是在对路由器进行人工重载或重新加电启动之前尽可能多地收集有关崩溃的信息。人工重载或重新加电启动之后,除 crashinfo 文件中成功保存的信息外,有关崩溃的所有其他信息都将丢失。下面的输出内容显示了有关崩溃的一些信息。 若您可以通过Cisco设备获得show version、show stacks、show context或show tech support命令输出,则可通过这些输出来显示潜在的问题和修补方法。若要使用这些信息,登录并启用 ,但您必须是注册用户。
崩溃类型 show version和show stacks命令输出可显示所发生崩溃的类型,如:总线错误或软件强制崩溃。您还可以通过crashinfo和show context命令来获取有关崩溃类型的信息。对于某些较新的Cisco IOS软件版本,没有明确显示崩溃原因(例如,显示内容为"Signal = x",其中x是一个数字)。若要了解这些数字所表示的意义,请参照通用接口处理器崩溃原因代码。例如:"Signal = 23"是指软件强制崩溃。根据下面的链接来解决路由器上所发生的特定类型的崩溃: 路由器模块崩溃在某些情况下,只是特定的路由器模块崩溃,而不是整个路由器崩溃。下列文件对如何解决某些路由器模块上的崩溃进行了说明: 显示崩溃情况的输出范例 Router#show version Cisco Internetwork Operating System Software IOS (tm) RSP Software (RSP-PV-M), Version 12.0(10.6)ST, EARLY DEPLOYMENT MAINTENANCE INTERIM SOFTWARE Copyright (c) 1986-2000 by cisco Systems, Inc.
