思科4506交换机重置：

加电30秒，Ctrl - C，进入ROMMON模式

rommon1>confreg

Configuration Summary :
=> load ROM after netboot fails
=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable

do you wish to change the configuration? y/n [n]: y
enable "diagnostic mode"? y/n [n]: n
enable "use net in IP bcast address"? y/n [n]: n
disable "load ROM after netboot fails"? y/n [n]: n
enable "use all zero broadcast"? y/n [n]: n
enable "break/abort has effect"? y/n [n]: n
enable "ignore system config info"? y/n [n]: y （相当于0x2142，启动时跳过配置文件）

change console baud rate? y/n [n]: n

change the boot characteristics? y/n [n]: n

Configuration Summary :
=> load ROM after netboot fails
=> ignore system config info
=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable

do you wish to save this configuration? y/n [n]: y

rommon2>reset

重启后是初始配置，保存后覆盖原来的配置

rommon 1 >confreg

Configuration Summary :
=> load rom after netboot fails
=> ignore system config info

=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable

do you wish to change the configuration? y/n [n]: y
enable "diagnostic mode"? y/n [n]: n
enable "use net in IP bcast address"? y/n [n]: n
disable "load rom after netboot fails"? y/n [n]: n
enable "use all zero broadcast"? y/n [n]: n
enable "break/abort has effect"? y/n [n]: n
disable "ignore system config info"? y/n [n]: y （相当于0x2102，启动配置文件）

change console baud rate? y/n [n]: n

change the boot characteristics? y/n [n]: y

enter to boot:
0 = disable autoboot
1 = the first file from internal flash device
2 = commands specified in 'BOOT' environment variable
[2]:

Configuration Summary :
=> load rom after netboot fails
=> console baud: 9600
=> autoboot from: commands specified in 'BOOT' environment variable

do you wish to save this configuration? y/n [n]: y
You must reset or power cycle for new configuration to take effect
rommon 2 >reset

4506交换业务板上，有几个端口出现了faulty状态，亮黄灯，不知是软件问题还是硬件问题。

2950交换机重置（请参照博客“交换机密码恢复”）

2950交换机堆叠：主交换机，上联口做TRUNK，配置管理地址和默认网关，成员交换机不用配

cluster enable 1 1
cluster member 2 mac-address 成员交换机MAC地址（可用show cluster candidates查看）
cluster member 3 mac-address 成员交换机MAC地址（遇到问题，当添加某成员时，出现“password mismatch”的错误提示，检查过密码相同，最后在成员交换机cluster commander-address 主交换机MAC地址，这样就可以了，但是不明白是怎么回事）

Show Cluster members查看集群成员

配置完成后，会自动添加下面的ACL：

ip access-list extended CMP-NAT-ACL
dynamic Cluster-HSRP deny ip any any
dynamic Cluster-NAT permit ip any any
