防火墙不断启动
Use BREAK or ESC to interrupt boot.
Use SPACE to begin boot immediately.
按下ESC进入监控模式
监控模式下的显示和交换机路由器没有什么区别。命令格式也大同小异只要大家变通一下就不难恢复。

确认线路是否连通,开启TFTP软件 (这里说明下我测试是ASA5505 所以接的E0/0口。不知道设备该接什么口可以用set“PORT=Ethernet0/0”

导入后设备重启,现在有了IOS 能进去
Type help or '?' for a list of available commands.
ciscoasa> en
但现在IOS也没有装入设备,而是从tftp引导启动设备,断开TFTP服务器就会从新进入监控模式。这一点当设备启动完毕后可以用show version命令看到:
System p_w_picpath file is "tftp://192.168.0.1/asa802-k8.bin"
现在需要把IOS存入设备,但是现在防火墙和PC已经不能通信
ciscoasa# ping 192.168.0.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.0.1, timeout is 2 seconds:
No route to host 192.168.0.1
Success rate is 0 percent (0/1)
因为刚才是在监控模式下,现在需要配置让PC和防火墙从新通信(具体型号具体设置,下面已我手上的5505为例)
interface Vlan1
nameif inside
security-level 100
ip address 192.168.1.1 255.255.255.0
!
interface Vlan2
nameif outside
security-level 0
ip address 192.168.0.2 255.255.255.0
!
interface Ethernet0/0
switchport access vlan 2
现在测试
ciscoasa# ping 192.168.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 192.168.1.1, timeout is 2 seconds:
!!!!!
Success rate is 100 percent (5/5), round-trip min/avg/max = 1/1/1 ms
已经能通信,下面拷贝IOSASDM存入设备
ciscoasa# copy tftp://192.168.0.1/asa802-k8.bin disk0:/asa802-k8.bin
Address or name of remote host ?
Source filename ?
Destination filename ?
Accessing tftp://192.168.0.1/asa802-k8.bin. ... !!!!!!!!!!!!!!!!!!!
因为删除的是flash 现在还需要导入ASDM (注意ASDMIOS的兼容,不兼容如下图)

Destination filename ?
Accessing tftp://192.168.0.1/asdm-602.bin.. ... !!!!!!!!!!!!!!!!!!!
现在可以看见IOS以后在设备上
