这里，根据消息类型确定消息的消息模式，消息模式包括请求IP模式和分配IP模式；当消息模式为请求IP模式时，确定所述网口的类型为LAN网口；当消息模式为分配IP模式时，确定所述网口的类型为WAN网口。具体的，当消息类型为DHCP请求报文时，所述消息的消息模式为请求IP模式，所述网口的类型为LAN网口，所述设备配置为服务器端；当消息类型为DHCP响应报文时，该消息的消息模式为分配IP模式，该网口的类型为WAN网口，设备配置为DHCP客户端；当消息类型为PPPOE响应报文时，该消息的消息模式为分配IP模式，该网口的类型为WAN网口，该设备配置为PPPOE客户端。
该方法还包括：当所述确定的网口类型与所述网口当前的配置的类型不同时，将所述设备的网口的类型切换至所述确定的网口类型。也就是说，当步骤S103确定的网口类型为WAN网口，而该网口当前配置的网口类型为LAN网口，则将该网口的类型由WAN网口切换为LAN网口；当步骤S103确定的网口类型为LAN网口，而该网口当前配置的网口类型为WAN网口，则将该网口的类型由LAN网口切换为WAN网口。
需要说明的是，当所述确定的网口类型与所述网口当前的配置的网口类型不同时，将所述设备的网口的类型切换至所述确定的网口类型，当所述确定的网口类型与所述网口当前的配置的类型相同时，对网口类型不做切换，保留原来的网口类型。
实施例二
本发明实施例二具有复用以太网口的设备CPE的复用以太网口的初始状态为WAN网口为例，对本发明实施例一提供的识别网口类型的方法做进一步说明，但需要说明的是，复用以太网口的初始状态也可为LAN网口，本发明对此不做限制。
如图2所示，该方法包括：
S201：CPE初始化为WAN网口；
CPE在开机后可初始化为宽带模式并将复用以太网口初始化为WAN网口，以此作为初始模式。在初始化之后，CPE开启监听申请IP功能，实时监听通过复用以太网口接入CPE的接入设备是否向CPE发送了DHCP请求报文，此处包括通过复用以太网口接入的接入设备申请ip、wifi用户申请ip、其它以太网口申请ip等申请IP功能。CPE在开启监听申请IP功能的同时，周期性的向复用以太网口对应的网卡发送DHCP请求报文，其中，DHCP请求报文为用于申请IP的请求报文。
这需要说明的是，实时监听和周期性的发送请求报文这两部分任务分可属于不同的进程，由不同的进程执行，但都属于CPE自身要完成的任务。
S202：接收到接入设备接入的接入信号后，判断来自接入设备的交互消息的接入类型，确定复用以太网口的类型。
若收到来自复用以太网口接入的设备发出的DHCP请求报文等用于申请IP的请求，则确定接入CPE的接入设备为客户端，此时执行步骤203；
S203：调整复用以太网口的类型；具体的，将CPE的复用以太网口的类型切换为LAN网口，相应的，将CPE切换为网关模式，CPE配置为服务器端。
若收到来自复用以太网口接入的设备发出的DHCP响应报文或PPPOE响应报文等用于分配IP的消息，则确定接入CPE的接入设备为DHCP服务器端或PPPOE服务器端，保持CPE的复用以太网口的类型为WAN网口，CPE为宽带模式，配置为DHCP客户端或PPPOE客户端。
收到来自复用以太网口接入的设备发出的DHCP响应报文或PPPOE响应报文两种分配报文的消息，CPE根据接收到的消息在宽带模式下有两种分配ip的方式：DHCP方式、PPPOE方式；
当接收到的是DHCP响应报文则说明接入的服务器端为DHCP服务器， 此时将CPE设定为DHCP宽带模式；当接收到的是PPPOE响应报文则说明接入的服务器端为PPPOE服务器，此时将CPE设定为PPPOE宽带模式。
需要说明的是，无论此时CPE为4G网关模式、DHCP宽带模式、PPPOE模式，CPE内部仍将周期性向复用以太网口发送申请ip请求，所发送请求包括PPPOE请求和DHCP请求，从而能够防止通过复用以太网口接入设备的形式(客户端<----->服务器)发生变化。
在本发明实施例中，上电后CPE内部周期性向复用以太网口对应的网卡发送DHCP请求、PPPOE请求并且不断监听通过复用以太网口接入CPE的设备是否发送了DHCP请求，在识别LAN网口和WAN网口的过程中涉及到三种过程：PPPOE-server过程、DHCP-server过程以及客户端过程，当接收到接入设备的接入信号后，这三种过程中的消息交互具体如下：
a.发现PPPOE-server过程：
PPPOE发现阶段，CPE广播发送PADI查找PPPOE服务器。当网络内有PPPOE服务器并且收到了CPE发送的PADI报文则会向CPE回应PADO。当CPE在收到PPPoE服务器发送的PADO之后向PPPOE服务器发送PADR，PPPOE服务器向CPE回应PADS。
当CPE周期性的发送PPPOE请求报文后收到PADO或PADS报文，则确定当前连接的是否是PPPOE服务器，若收到PADO报文或PADS报文则可确定CPE通过复用以太网口连接了PPPOE服务器，则将复用以太网口设置为WAN口，CPE配置为PPPOE宽带模式。
b.发现DHCP-server过程：
当CPE作为客户端第一次向DHCP服务器申请ip需要经历DHCPDiscover-(CPE发送给DHCP服务器)--->DHCP Offer(DHCP服务器发送给CPE)---->DHCP Request(CPE发送给DHCP服务器)---->DHCP Ack(DHCP服务器发送给CPE)四个步骤。
当CPE在发出DHCP请求报文后收到服务器端发来的DHCP Offer报文或DHCP Ack报文，则可确定当前复用以太网口上连接的是否是DHCP服务器，若收到DHCP Offer报文或DHCP Ack报文，可确定CPE通过复用以太网口连接了DHCP服务器，则将复用以太网口设置为WAN口，CPE配置为DHCP宽带模式。
c.发现客户端过程：
当CPE作为服务器端，接入CPE的客户端通过DHCP方式申请ip地址需要经历DHCPDiscover(客户端发送给CPE)---->DHCPOffer(CPE发送给客户端)---->DHCPRequest(客户端发送给CPE)---->DHCPAck(CPE发送给客户端)四个步骤，如果CPE收到通过复用以太网口发来的DHCPDiscover或DHCP Request消息则认为当前连接的设备是客户端设备，此时将复用以太网口设置为LAN口，将CPE当前模式设置为网关模式。
在本发明实施例提供的自动识别LAN网口和WAN网口的方法中，CPE初始时将复用以太网口可作为LAN网口也可作为WAN网口。在从LAN网口切换至WAN网口或从WAN网口切换至LAN网口的过程中，通过将WAN侧IP地址、CPE的DNS地址、与网卡相关的iptables规则等进行更新，从而实现WAN端和LAN口之间的切换，以适应CPE的上行通路的变化。
