[0067] 其中,在本发明实施例中,抓设备中可W存储Client MAC表、MonitorMAC表、W及Normal MAC表,从Client CE侧进入邸的报文根据Client MAC表进行转发,从Monitor CE侧进入抓的报文根据Monitor MAC表进行转发、从Normal CE侧进入抓的报文根据Normal MAC 表进行转发。 [0067] wherein, in the embodiment of the invention, the grasping device may be W stored Client MAC table, MonitorMAC table, W, and Normal MAC table, entering Di from Client CE packets is forwarded in accordance with Client MAC table, the Monitor CE grasping the side entry packets according Monitor MAC forwarding table, into the side catch from Normal CE packets are forwarded according Normal MAC table.

[0068] 为了更好地理解本发明实施例提供的技术方案,下面结合具体的应用场景对本发明实施例提供的技术方案进行更加详细的描述。 [0068] In order to better understand the technical solutions provided by the embodiments of the present invention, in conjunction with the following specific application scenario of the technical solution provided in embodiments of the present invention will be described in more detail.

[0069] 参见图2,为本发明实施例提供的一种具体应用场景的架构示意图。 [0069] Referring to Figure 2, a schematic diagram of the architecture of a specific application scenario according to an embodiment of the present invention. 在该实施例中,在抓1上为CE10和CE12之间建立Client-Monitor组,CE10为Client CE设备,CE12为Monitor CE设备(即该实施例中Client CE设备与Monitor CE设备与同一邸相连)。 In this embodiment, the grip 1 is established between the CE10 and CE12 Client-Monitor group, CE10 to Client CE devices, CE12 to Monitor CE devices (i.e. Client CE device and Monitor CE device and the same in this embodiment is connected to Di ).

[0070] 在抓1上为Client-Monitor组创建两种类型的MAC表,Client MAC表和Monitor MAC表,其中,Client MAC表适用于从CEIO侧来的流量,从CEIO侧进入该EVI实例内的报文查询Client MAC表;Monitor MAC表适用于从CE12来的流量,从CE12侧进入该EVI实例内的报文查询Monitor MAC表。 [0070] The grip 1 create two types of MAC Client-Monitor group table, the MAC address table and Monitor Client MAC address table, wherein, MAC Client table applies to CEIO flow rate from the side, from entering CEIO inner side of the EVI instance Client MAC query packet table; Monitor MAC table suitable for the flow rate to the CE12, CE12 from the side into the query packet within the Monitor EVI instance the MAC address table. 此外,EDI上还可W存储普通的MAC表,即Normal MAC表,适用于从NormalCE(如CE11)侧过来的流量,从CE11侧进入该EVI实例内的报文查询NormalMAC表。 Furthermore, W may also be stored on the ordinary EDI MAC table, the MAC address table Normal i.e., coming from the suitable NormalCE (eg CE11) side of the flow, which enters from the side CE11 EVI NormalMAC query packet within the table instance. 其中,在本发明实施例中,对Normal CE发出的流量W及转发到Normal CE的流量不需要进行监控。 Wherein, in the embodiment of the present invention, the flow rate W of Normal CE issued and forwarded to the traffic Normal CE does not require monitoring.

[0071] 在本发明实施例中,MAC学习需要进行特殊处理。 [0071] In an embodiment of the present invention, MAC learning require special handling. 具体的,EDI对于CE10(即Client CE)侧进入的报文,需要进行源MAC学习,但是学习到的MAC信息不下发到Client MAC表中, 而是将MAC信息同步到Monitor MAC表中,Monitor MAC表中对应该源MAC地址记录的出端口为抓1与CE10连接的端口巧odlO);此外,还需要将学习到的MAC信息同步到Normal MAC表中,Norma 1 MAC表中对应该源MAC地址记录的出端口为抓1与CE12 (即Mon i torCE )连接的端口(Portl2)。 Specifically, EDI for CElO (i.e. Client CE) side of the incoming packets, source MAC address learning is required, but the learned MAC Client information is not delivered to the MAC table, but the information is synchronized to the Monitor MAC MAC table, Monitor MAC table to be the source MAC address recorded in the port catch port Qiao odlO 1 is connected to CE10); and also need to learn the MAC information synchronized to Normal MAC table, Norma 1 MAC table to be the source MAC recording an address port and a grip CE12 (i.e. Mon i torCE) connected to a port (Portl2).
