ASA升级

1、开启TFTP server，并且保证设备和TFTP server可达。
2、上传镜像文件到ASA：
ciscoasa# copy tftp: disk0: >>>>拷贝镜像到ASA disk0
Address or name of remote host []? 192.168.111.2
Source filename []? asa917-20-k8.bin
Destination filename [asa917-20-k8.bin]? asa917-20-k8.bin
Accessing tftp://192.168.111.2/asa917-20-k8.bin...!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

ciscoasa# dir >>>>查看目前镜像以及所剩的空间

3、验证完整性：（可选）
ciscoasa# verify disk0:asa917-20-k8.bin

4、修改启动镜像
ciscoasa(config)# boot system disk0:/asa917-20-k8.bin

5、查看启动镜像及顺序
ciscoasa# show bootvar

BOOT variable = disk0:/asa842-k8.bin;disk0:/asa917-20-k8.bin
Current BOOT variable = disk0:/asa842-k8.bin;disk0:/asa917-20-k8.bin
CONFIG_FILE variable =
Current CONFIG_FILE variable =

6、去掉之前的镜像或删除原镜像的启动路径（还是删除启动路径的好）
ciscoasa(config)# delete disk0:/asa842-k8.bin
Delete filename [asa842-k8.bin]?

Delete disk0:/asa842-k8.bin? [confirm]
ciscoasa(config)# dir

Directory of disk0:/

=======================================
ciscoasa(config)# no boot system disk0:/asa842-k8.bin
ciscoasa# sho bootvar

BOOT variable = disk0:/asa842-k8.bin;disk0:/asa917-20-k8.bin >>>发现还是存在
Current BOOT variable = disk0:/asa917-20-k8.bin
CONFIG_FILE variable =
Current CONFIG_FILE variable =
ciscoasa# wr memory >>>保存后生效

ciscoasa# show bootvar

BOOT variable = disk0:/asa917-20-k8.bin
Current BOOT variable = disk0:/asa917-20-k8.bin
CONFIG_FILE variable =
Current CONFIG_FILE variable =

7、重启设备
ciscoasa(config)# reload

8、查看版本
ciscoasa# sh version
