Anyconnect VPN users are not getting correct DHCP lease time. even though its configured for 5 days on windows server its gets expired in 45 mins. Other scopes on the server are given the correct lease time. Only scope used by the ASA is having issues. can anyone please shed...
The DHCP client renews its IP configuration data prior to the expiration of the lease time. If the lease period expires and the DHCP client has not yet renewed its IP configuration data, then the DHCP client loses the IP configuration data and begins the DHCP lease generation process again. ...
IV. DHCP监听绑定表里的Lease列就是每个客户端对应的DHCP租约时间。当客户端离开网络后,该条目并不会立即消失。当客户端再次接入网络,重新发起DHCP请求以后,相应的条目内容就会被更新。如上面的000F.1FC5.1008这个客户端原本插在Fa0/1端口,现在插在Fa0/3端口,相应的记录在它再次发送DHCP请求并获得地址后会更新为...

在DHCP Pool配置模式下,使用命令lease {days[hours][minutes]|[infinite]}修改IP地址池的地址租用时间。该值的设定允许以日、时、分、秒为单位,也可以设置为无限时间(Infinite)。若要调整DHCP客户的地址租用时间为3小时30分,则在Cisco路由器上执行的配置语句如下: [*]结果...
解析 B 可以在DHCP Pool配置模式下.使用“lease”命令改变IP地址池的地址租用时问。该值的设定允许以日、时、分、秒为单位,也可以没置为无限时间(infinite)。具体配置格式为:lease{days[bours][minutes]|infinite}。本题将DHCP客户一的地址租用时间调整为3 h30 min,配置语句为:lease 0 3 30。
当DHCP服务器从DHCP客户端发现DHCPdiscover中发现可识别的VCI时,它将其DHCPoffer中的映射供应商特定信息作为DHCP选项43返回给客户端。在DHCP服务器上,在为LAP提供IP地址的每个DHCP池(作用域)中定义选项43。 RFC 2132将DHCP服务器必须返回供应商特定信息定义为DHCP选项43。RFC允许供应商定义封装的供应商特定子选项代码,...
解析 B 在Cisco路由器DHCP Pool配置模式下,`lease`命令的格式为`lease {days [hours] [minutes] | infinite}`。题目要求设置时间为3小时30分钟,需将天数设为0,小时为3,分钟为30。选项中仅B(`lease 0 3 30`)正确按序包含0天、3小时、30分钟。其他选项(如A缺少天数,C/D顺序错误)均不符合命令格式。
