简介

本文包含升级的您的Cisco NI-2 DSLAM一个逐步程序。必须在 TCP/IP 就绪工作站上安装 TFTP 服务器或远程复制协议 (RCP) 服务器应用。一旦安装了应用程序,则必须执行最低配置。首先,TFTP应用程序必须配置成TFTP服务器,而不是用作TFTP客户端。其次,必须指定出站文件目录。这是Cisco IOS 软件镜像存储的目录。大多数 TFTP 应用会提供一个帮助执行这些配置任务的设置例程。

升级 Cisco IOS 软件镜像

使用以下步骤升级Cisco IOS软件镜像。

  1. 在 TFTP 服务器的出站目录中安装新的 Cisco IOS 软件镜像。

    TFTP server寻找在此目录的DSLAM的Cisco IOS软件镜像。确保您想复制到您的闪存的镜像位于此目录中。

    每镜像的内存要求也在TFTP server的出局目录。使用 show version 命令,确认您有足够的内存。

  2. 建立一个控制台会话对DSLAM。

    这可以通过直接控制台连接或虚拟Telnet连接执行。直接控制台连接更喜欢,因为Telnet连接将丢失在软件安装的重新启动相位期间(请参阅步骤9)。控制台连接用反转电缆建立(浅黑或蓝色电缆),并且连接DSLAM的控制台端口到PC的COM-port。

  3. 启动PC的超级终端并且请使用以下设置:

    • 9600 bps

    • 8数据位

    • 0 个奇偶校验位

    • 1 个停止位

    • 无流控制

  4. 验证TFTP server有IP连通性对DSLAM。

    TFTP server必须有对DSLAM的一个网络连接,并且一定能ping TFTP软件升级瞄准的DSLAM的IP地址。要达到此, DSLAM接口和TFTP server必须二者之一有:

    • 在同一个范围的一个IP地址或;

    • 配置了默认网关。

    要验证,请检查TFTP服务器的IP地址。

    注意: 在您验证与您的TFTP server后的网络连通性,请通过发出一write memory命令写入对内存的所有更改在DSLAM。

    DSLAM#write memory
    Building configuration...
    [OK]
    DSLAM#
  5. 验证引导闪存镜像是ni2-dboot-mz.121-5.da1ni2-dboot-mz.121-4.da。如果它是,请去步骤14。如果它不是,请进入步骤6腾出Bootflash的空位。

    DSLAM#dir bootflash:
    Directory of bootflash:/
    
    1  -rw-     3361208   Jan 01 2000 00:05:11  ni2-dboot-mz.121-2.DA
     
    3801088 bytes total (439752 bytes free)
  6. 通过删除当前启动镜像的名称腾出Bootflash的空位。

    DSLAM#delete bootflash:ni2-dboot-mz.121-2.DA.bin
    Delete filename [ni2-dboot-mz.121-2.DA.bin]?
    Delete bootflash:ni2-dboot-mz.121-2.DA.bin? [confirm]
  7. 使用squeeze bootflash命令,恢复在Bootflash的可用空间。

    DSLAM#squeeze bootflash
    All deleted files will be removed. Continue? [confirm]
    Squeeze operation may take a while. Continue? [confirm]
    Squeeze of bootflash complete
  8. 复制启动镜像对Bootflash。

    DSLAM#copy tftp://171.69.89.140/ni2-dboot-mz.121-5.DA1.bin bootflash:
    Destination filename [ni2-dboot-mz.121-5.DA1.bin]?

  9. 输入全局配置模式并且设置配置寄存器为0x0000,以便NI-2在ROM监控器(ROMMON)模式将重新启动。

    DSLAM#configure terminal
    Enter configuration commands, one per line.  End with CNTL/Z.
    DSLAM(config)#config-register 0X0
    DSLAM(config)#exit
    
  10. 保存运行的配置并且重置系统。

  11. 如果看到BOOTLDR,在您输入set命令后,在Bootflash的镜像已经使用作为启动载入器;进入步骤13。否则,请去步骤12并且输入命令强制系统使用ni2-dboot-mz.121-5.bin作为启动载入器。

    rommon 1 > set 
  12. 请使用被移置的BOOTLDR删除变量和同步救ROMmon的状态,然后重新启动。

    当NI-2启动时,使用ni2-dboot-mz.121-5da.bin作为您的启动载入器。

    rommon 2 > unset BOOTLDR
    
    rommon 3 > sync
    
  13. 送回配置寄存器到0x2102并且重置系统。

    rommon 4 > confreg 0x2102
    rommon 5 > reset
    
  14. 显示开始ni2-闪存文件的名称并且请使用它作为文件名在步骤15。
