注：
最好配置虚拟MAC地址
shfailover显示配置信息
writestandby写入到备用的防火墙中
failover命令集如下：

3.配置telnet、ssh及http管理

aaaauthenticationsshconsoleLOCAL
aaaauthorizationcommandLOCAL
http192.168.40.0255.255.255.0management
ssh192.168.40.0255.255.255.0inside
4.vpn常用管理命令
shvpn-sessiondbfulll2l显示sitetosite之vpn通道情况
shipsecstats显示ipsec通道情况
shvpn-sessiondbsummary显示vpn汇总信息
shvpn-sessiondbdetaill2l显示ipsec详细信息
shvpn-sessiondbdetailsvc查看sslclient信息
shvpn-sessiondbdetailwebvpn查看webvpn信息
shvpn-sessiondbdetailfulll2l相当于linux下的ipsecwhack?
Cstatus如果没有建立连接，则表示ipsec通道还没有建立起来。
5.配置访问权限
可以建立对象组，设定不同的权限，如：
object-groupnetworktestgroup
descriptiontest
network-object192.168.100.34255.255.255.255
access-listinside_access_inline2extendedpermitipobject-groupallany
access-groupinside_access_inininterfaceinside
6.配置sitetosite之VPN
cryptoipsectransform-setESP-3DES-SHAesp-3desesp-sha-hmac
cryptomapoutside_map20matchaddressoutside_cryptomap_20_1
cryptomapoutside_map20setpfs
cryptomapoutside_map20setpeer218.16.105.48

tunnel-group218.16.105.48ipsec-attributes
pre-shared-key*
peer-id-validatenocheck
tunnel-group-mapenablerules
打打PFS并设定以IP地址作为peer名，一个接口只能有一个加密图
7.webvpn配置（sslvpn）

也可通过ASDM图形界面进行配置
登录后，可访问内部资源，如下例：
（客户端首先要安装Java插件jre-1_5_0-windows-i586.exe,并打开浏览器的ActiveX）
1）输入用户名和密码
2）出现工具条
3）在EnterWebAddress内输入192.168.40.8即可访问内部网站
4）在browsenetwork输入192.168.40.8即可访问共享文件
5）点击applicationaccess，即可查看端口转发设置，如使用putty访问本机的2023端口，则即可通过ssh登录192.168.40.8
8.远程拨入VPN
相关的ASA配置命令如下：
access-listinside_access_inextendedpermitipobject-groupremotegroupany
access-listinside_access_inextendedpermiticmpobject-groupremotegroupany
access-listremotevpn_splitTunnelAclstandardpermit192.168.100.0255.255.255.0

客户端设置如下：
9.日志服务器配置
loggingenable
loggingtimestamp
loggingemblem
loggingtrapinformational
loggingasdmwarnings
logginghostinside192.168.40.115formatemblem
loggingpermit-hostdown
vpn-simultaneous-logins3
10.Snmp网管配置
snmp-serverhostinside192.168.40.47communitytestsnmp
snmp-serverlocationDG-GTEST
snmp-servercontactjiangdaoyou:
6162
snmp-servercommunitytestsnmp
snmp-serverenabletrapssnmpauthenticationlinkuplinkdowncoldstart
指定主机后，192.168.40.47才可能进行管理
11.ACS配置
安装后管理：
http:
//ip:
2002通过ACS可以进行授权、认证等等很多功能
因内容太多，暂省略
12.AAA配置
Aaa服务器配置：
aaa-serverradius_dghost
keydfdfdfdf146**U
authentication-port1812
accounting-port1813
radius-common-pwdfdfdfdf146**U
对于拨入vpn的配置
tunnel-groupvg_testerpgeneral-attributes
address-poolciscovpnuser
authentication-server-groupradius_dg
default-group-policyvg_testerp
13.升级IOS

/asa721-k8.bin
bootsystemdisk0:
