【十大棋牌网赌软件】恢复HP GbE2c Ethernet Blade Switch for c-Class BladeSystem密码

一、故障背景

GbE2c以太网刀片交换机需要变更并备份配置，但交换机的管理密码丢失，无法登录对设备进行管理，所以需要重置交换机管理密码。

GbE2c交换机：HP GbE2c以太网刀箱交换机提供了全套工业标准的千兆以太网特征，共16个内部下联、5个上联以及2个内部互联。

交换机后面板说明（来源：官方手册）

Item	Description	Description
1	Reset button	Forces the switch to power up or reboot
2	Health LED	Off—Not powered up Green—Powered up and all ports match Amber—Indicates a problem such as a port mismatch. For more information,see the HP BladeSystem enclosure setup and installation guide.
3	UID LED
4	DB-9 management serial port
5	RJ-45 ports 20 - 24

GbE2c交换机的默认用户名和密码

User account	Description and tasks performed	Password
User	The user has no direct responsibility for switch management. He or she can view all switch status information and statistics, but cannot make any configuration changes to the switch.	user
Operator	The operator manages all functions of the switch. The operator can reset ports or the entire switch By default, the operator account is disabled and has no password.
Administrator	The super user administrator has complete access to all menus, admin information, and configuration commands on the switch, including the ability to change both the user and administrator passwords.	admin

二、故障处理

恢复管理密码需要准备的工具

- USB/RS232串口转换器

连接终端参数设置要求如下：

Parameter	Value
Baud rate	9600
Date bits	8
Parity	None
Stop bits	1
Flow control	None

1、重置GbE2c交换机模块，自检过程中当出现Memory Test时，按键-T；

Memory Test . //开始reset网络模块

Memory Test ...... //按shift+t

Manufacturing Mode //进入Manufacturing模式

2、交换机自检结束，随即提示进入诊断模式，输入诊断模式的密码admin以继续；

3、进入boot菜单；

>> Diagnostics# boot //输入boot

4、执行conf f，并再次重启，交换机将在下次使用出厂配置启动；

[Boot Menu]

image - Select Alteon OS image 1 or 2

conf - Set Production Mode Config Block (f, a, or b)

reset - Reset The Switch

>> Diagnostics# conf f //输入conf f

Next boot will use switch FACTORY (f) config block.

>> Diagnostics# reset //输入reset重启

Confirm reset [y/n]: y

三、经验总结

1、账户密码作为接入设备的重要凭据信息，一旦丢失，将无法管理设备，且重置密码时需要重新引导设备，甚至丢失原有配置，影响设备的连续运行，造成业务中断。

2、密码同样是保护信息安全的一个重要举措，为规范保密管理，保障IT基础设备安全使用和正常运行，应制定规范的密码管理制度，包括密码内容设置规则、密码定期更换机制、密码和口令的保存、使用等。

四、知识拓展

1、备份GbE2c刀片交换机配置

配置备份的作用，则主要用于以下两个场景出现时，进行配置恢复：

· 交换机在运行过程中发生配置损坏

· 交换机由于硬件故障需要被替换

登录交换机：

[Main Menu]

info     - Information Menu
stats    - Statistics Menu
cfg      - Configuration Menu
oper     - Operations Command Menu
boot     - Boot Options Menu
maint    - Maintenance Menu
diff     - Show pending config changes [global command]

apply - Apply pending config changes [global command]

save - Save updated config to FLASH [global command]

revert - Revert pending or applied changes [global command]

exit - Exit [global command, always available]

>> Main#

进入配置菜单：

Main# /cfg

[Configuration Menu]

sys - System-wide Parameter Menu port - Port Menu
ip - IP Menu
vlan - VLAN Menu

stp - Spanning Tree Menu

snmp - SNMP Menu

pmirr - Port Mirroring Menu

trunk - Trunk Group Menu

setup - Step by step configuration set up

dump - Dump current configuration to script file

ptcfg - Backup current configuration to tftp server

gtcfg - Restore current configuration from tftp server

Configuration# dump

script start "HP c-Class GbE2c Switch" 4 /**** DO NOT EDIT THIS LINE!

/* Configuration dump taken 7:04:51 Sun Jan 1, 2006

/* Version 2.0.0, Base MAC address 00:00:00:00:00:00

/* RackId: Default RUID, RackName: UnnamedRack

/* Enclosure: SGH*******, EnclosureName: SGH*******

……………snip………d…

script end /**** DO NOT EDIT THIS LINE!

执行dump，GbE2c将交换机的当前配置打印至终端屏幕，手工复制配置信息并保存为脚本文件，以便于恢复使用。

2、恢复GbE2c刀片交换机配置

进入配置菜单，将dump出的配置信息粘贴至终端中并按回车键确定。

>> Main# diff //检查配置是否加载

>> Main# apply //应用配置，使配置生效

>> Main# save //保存配置
