引擎:WS-SUP720-3B 主备各一块

线路卡:WS-X6148X2-45AF 五块。

Cisco CompactFlash Memory Card, 128 MB 2块。

该设备原为cisco ios模式,但因当时IOS不支持WS-X6148X2-45AF 线路卡所以采用CatOS模式以支持上述线路卡,后思科推出支持的IOS版本s72033-advipservicesk9_wan-mz.122-18.SXF.bin,客户要求再次改为IOS版本。此两块 CompactFlash Memory Card曾在原IOS模式下格式化过,在此次升级过程中两种模式下(catos和IOS)竟都能写入。以下为升级过程:



1.首先将备份引擎拔下(支持热插拔),在catOS下将IOS映象文件拷入CompactFlash Memory Card 中。因IOS大小为70多兆所以用TFTP无法传也不可靠,所以用FTP传输,输入set ftp username;set ftp password 设置好调用的FTP用户名和密码。执行:



SWITCH_1> (enable) copy ftp disk0:

IP address or name of remote host <172.21.239.40>?

Username for ftp?

Password for User ftp<>:

Name of file to copy from ? s72033-advipservicesk9_wan-mz.122-18.SXF.bin

127893504 bytes available on device disk0, proceed (y/n) ? y

Loading s72033-advipservicesk9_wan-mz.122-18.SXF.bin

File disk0:s72033-advipservicesk9_wan-mz.122-18.SXF.bin checksum verified and is Ok.

File has been copied successfully.

SWITCH_1> (enable) dir disk0:

2 -rw- 76599844 Sep 17 2005 09:52:11 s72033-advipservicesk9_wan-mz.122-18.SXF.bin

51290112 bytes available (76603392 bytes used)



2.查看当前交换机启动变量。寄存器值为0x2102,下一步将修改此值为0x0



SWITCH_1> (enable) sh boot

BOOT variable = bootflash:cat6000-sup720cvk8.8-4-3.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x2102

ignore-config: disabled

auto-config: non-recurring, overwrite, sync disabled

ROMMON console baud: 9600

oot: p_w_picpath specified by the boot system commands

Image auto sync is enabled

Image auto sync timer is 120 seconds



3.修改寄存器值为0x0



SWITCH_1> (enable) set boot config-register 0x0

Configuration register is 0x0

ignore-config: disabled

auto-config: non-recurring, overwrite, sync disabled

ROMMON console baud: 9600

oot: the ROM monitor



4.确认此值已修改,并reset。



SWITCH_1> (enable) sh boot

BOOT variable = bootflash:cat6000-sup720cvk8.8-4-3.bin,1;

CONFIG_FILE variable = bootflash:switch.cfg

Configuration register is 0x0

ignore-config: disabled

auto-config: non-recurring, overwrite, sync disabled

ROMMON console baud: 9600

oot: the ROM monitor

Image auto sync is enabled

Image auto sync timer is 120 seconds

SWITCH_1> (enable) reset



5.系统重启进入ROMMON模式。输入SET查看环境变量。

6.输入CONFIG_FILE=将该变量值清空。输入sync写入到NVRAM中,再reset,系统重启进入ROMMON模式。

8.检查转换后运行的IOS版本,正确无误。

9.用IOS格式格式化sup-bootflash



Router#format sup-bootflash:

Format operation may take a while. Continue?

Format operation will destroy all data in "sup-bootflash:". Continue?

Format of sup-bootflash complete

Router#dir sup-bootflash:

Directory of sup-bootflash:/

No files in directory

65536000 bytes total (65536000 bytes free)



10.该步为可选步骤,用来验证闪存卡是否可写入,若能写入则不用再格化。可用较小的IOS文件用TFTP协议往disk0写入IOS文件。此次转换过程中发现可以写入,所以没重新格式化闪存卡,也省去了再传IOS的步骤。

11.修改启动参数。下次启动交换机时直接用disk0中的IOS映象启动。保存



Router(config)#boot system flash disk0:s72033-advipservicesk9_wan-mz.122-18.SXF.bin

Router(config)#

Router#wr m

Building configuration...

12.显示交换处理器的寄存器值,因在catos模式下我们修改交换处理器的寄存值为0x0,所以最后还要将其修改回0x2102.

Router#remote command switch show boot

BOOT variable = bootflash:cat6000-sup720cvk8.8-4-3.bin,1;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x0

Router(config)#config-register 0x2102

Router(config)#

Router#wr m

Building configuration...

Router#remote command switch show boot

BOOT variable = disk0:s72033-advipservicesk9_wan-mz.122-18.SXF.bin,1;

CONFIG_FILE variable does not exist

BOOTLDR variable does not exist

Configuration register is 0x0 (will be 0x2102 at next reload)

Router#reload

至此主引擎转换完毕。关闭电源,将拔出主引擎,插入备份引擎,重复上述将其转换。备份引擎转换成功后,可直接将主引擎插入。此时备份引擎处于active 状态,而主引擎处于hot standby状态。等主引擎完全启动后,可将备份引擎插拔一次,这样将恢复成主为active 备为hot standby。

该版本下redundancy模式为SSO模式,因此在插拔任何一块引擎情况下,ping包没有丢失。
