測試： （1）在pc上運行VPN client，連接vpn access server。 （2）ipconfig/all，查看獲取到的ip地址與其他參數(shù)。 （3）在router，show cry isa sa,看連接是否成功。 （4）從router，ping client已經(jīng)獲取到的ip地址，通過。 （5）從client，ping router的lo0配置的地址172.16.1.1，通過。 （6）查看vpn client軟件的status--statistics,可以看到加密與解密的數(shù)據(jù)量。 （7）1720上show cry ip sa, 也可以查看加密與解密的數(shù)據(jù)量。
常用調試命令： show cry isakmp sa show cry ipsec sa clear cry sa clear cry isakmp debug cry isakmp #####這是最常用的debug命令，vpn連接的基本錯誤都可以用它來找到 debug cry ipsec 本文作者:html教程
