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
直到线路卡在允许状态，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。

注意： 如果 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。 注意 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。 注意线路卡在一 个允许状态(IOS RUN)，如显示在下面的 show diag命令输出。当 线路卡在一个允许状态时，您能升级固件。

下一个步骤将升级线路卡。执行此，使用 upgrade命令。 下面是 upgrade命令选项 列表。

 mfr_2#upgrade ?
  all  all GSR rom images
  fabric-downloader  fabric downloader
  mbus-agent-rom  mbus agent rom
  post  Power On Self Test
  rom-monitor  rom monitor
 

由于有一个ROM监控器警告在 show version命令输出，您 在卡需要升级ROM监控器。upgrade命令在句法示例显示如下 ：
 mfr_2#upgrade rom-monitor ?
  all  all slots
  slot  slot number
  <cr>
 mfr_2#upgrade rom-monitor slot ?
  <0-7>  slot number
 mfr_2#upgrade rom-monitor slot 0
 ========= Line Card (Slot 0) =======
 EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE vvvvvvvvvvvvvvvvvv
 mfr_2#
 LOT 0:Upgraded linecard ROM monitor succe fully
 

其次，升级矩阵下载程序。 upgrade 命令在句法示例显示如下：

 mfr_2#upgrade fabric-downloader slot 0
 ========= Line Card (Slot 0) =======
 EEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE vvvvvvvvvvvvvvvvvv
 mfr_2#
 LOT 0:Upgraded linecard fabric loader succe fully
 

因为有卡在插槽1和插槽2，您能升级那些。 upgrade命令在句法示例显示如下：

 mfr_2#upgrade all ?
  all  all slots
  slot  slot number
  <cr>
 mfr_2#upgrade all all
 This will take around 7-10 minutes for a full cha is
 E ure that GSR is not power cycled during the upgrade

注意： 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。如果版本不配比，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。

在上面 的例子，警告消息表明您需要强制线路卡重新载入固件。您 能强制线路卡通过使用microcode reload命令重新载入 固件在配置，如下所示。

 mfr_2# configure terminal
 Enter configuration commands, one per line.  End with CNTL/Z.
 mfr_2(config)#microcode reload

有选择的重新加载
如下所示发出microcode reload命令 的 选项。注意您能根 据每个线路卡有选择性地重新载入微码。

特别注意事项
在升级之前，如果线路卡不过来，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)方面的一个容易的机制在线路卡。 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：

 ervice 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。如果他们兼容，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

 ervice 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
