前言
本文在Cisco 12000系列互联网路由器线路卡描述如 何在Cisco IOS软件升级以后升级® 微码。 升级线路卡固件取消 警告：老... 消息从 show version命令输出在路由 器。
逐步程序
直到线路卡在答应状态，请勿使用 upgrade 命令在本文。您能验证线路卡的状态用 show gsr命令。关于运 行Cisco IOS软件版本11.2(15)gs2以上的路由器，参见 此信息。
注重： 假如 升级ROM监控器，您 必须 重新载入线路卡。
一旦Cisco IOS软 件被升级了并且路由器被重新载入了，这不 意味着线路卡被升级了到最新的固件。 确定如 果有老版本问题，使用 show version命令，如下所示。 注重 警告消息在下面的show version命令输出的 底部。这些警告消息指 示什么需要被升级。

从以上警告消息 ，我们能发现我们需要升级ROM监控器和矩阵下载程序。
使用 show diag 命令确定什么线路卡您升级和其当前状态。 注重线路卡在一 个答应状态(IOS RUN)，如显示在下面的 show diag命令输出。当 线路卡在一个答应状态时，您能升级固件。

This will take around 7-10 minutes for a full chassis
Ensure that GSR is not power cycled during the upgrade

1) GRP ROM upgrade typically takes 30 to 240 seconds.
2) After GRP ROM upgrade the GRP will be reset.
Continue GRP ROM upgrade? [yes/no]: n
注重： 在本例中，因为 GRP ROM当前修正与新修正版，是等同的我们没有升级千兆路由处理 器(GRP) ROM。假如版本不配比，则您应该继续和升级 GRP ROM。 升级GRP ROM造成机箱重新载入。
您能现在使用 show version命令发现是否有 任何个剩余的 警告：老。 消息。

非凡注重事项
在升级之前，假如线路卡不过来，输入以下命令：
gsr# configure terminal
gsr(config)# service download-fl
gsr(config)# microcode reload
gsr(config)# ^Z <--This represents the CNTL + Z key combination.
这些命令强制GRP下载其矩阵下载程 序的自己的版本到线路卡在尝试之前开始在线路卡的Cisco IOS软件 。
在线路卡是UP之后，您能如上所述 升级线路卡。当完成升级线路卡的时您，从 配置删除 service download-fl 命令。
线路卡升级过程为Cisco IOS 软件版本11.2(15)gs2以上
更新的软 件镜象，有升级固件的所有(即ROM监控器和矩阵加载器，不包括 MBUS ROM 代理)方面的一个轻易的机制在线路卡。 输入以下 命令在全局配置模式在Cisco 12000 系列互联网路由器自动地升级 固件在线路卡：
service upgrade [all rommon fabric-loader]
service upgrade all configuration命令不升级MBUS ROM代理由于向后兼容性的原因(即 一个更旧的MBUS ROM版本可能不在新的卡运作)。MBUS代理需 要使用upgrade mbus-agent-all或upgrade all命令手工 被升级。
功能
此命令自动地删除警告消息关于 DOWNREV 线路卡ROM监控器或矩阵下载程序。当ROM 监控器 和矩阵加载器版本不是与Cisco IOS软件兼容时，它自动地也升级 GSR线路卡闪存固件镜象。假如他们兼容，升级不发生。 在升级发生之后，将自动地重置线路卡并且没有需要微型重 新载入。当您重新载入路由器或微型重新载入线路卡时，配 置命令进入作用。
最坏局面的另外的 引导程序时期(升级ROM监控器和矩阵加载器)是大约30秒。
此配置命令 的可用性
此配置命令是仅可用的在 Cisco IOS软件版本11.2(15)gs2以上。
固件术语
使用线路卡ROM监控器启动线路卡和把柄MBUS信息。 用于线路卡矩阵加载器接受Cisco IOS软件下载在GSR交换矩 阵的。
命令 句法
service upgrade [all rommon fabric-loader]
那里：
所有 自动地升级ROM监控器和 矩阵加载器。
rommon 自动地升级仅ROM 监控器。
矩阵加载器 自动地升级仅矩阵加载器。
使用示例
自动地升级ROM监控器和矩阵加载器，输入以下命令 ：
router(config)#service upgrade all
自动地升级仅ROM监控器，输入以 下命令：
router(config)#service upgrade rommon
自动地升级仅矩阵加载器 ，输入以下命令：
router(config)#service upgrade fabric-loader
