用SNMP设置来管理好Cisco设备

Switch#configure terminal 
Enter configuration commands, one per line. 
Switch(config)#
Switch(config)#snmp-server community public RO 
在这里public是RO（只读）的共同体的密码
Switch(config)#snmp-server community private RW 
在这里private是RW(读写)的共同体的密码
Switch(config)#exit 
退出
Switch#write memory 
Building configuration...存盘

出于网络安全的考虑，一是密码需要修改为较安全的密码，二是不建议设置RW（读写）的SNMP设置。
2.如果是Cisco 3550交换机的话，配置SNMP如下：

snmp-server community public RO 
snmp-server community private RW

3.Cisco 7507路由器

snmp-server community public RO

4.Cisco PIX520防火墙

snmp-server community public

其实在Cisco设备上进行SNMP设置的命令基本上是一样的。
