【正文】 ource interfaceid, specify the source port to monitor. Valid interfaces include physical interfaces and portchannel logical interfaces (portchannel portchannelnumber). Valid portchannel numbers are 1 to 48. ? For vlanid, specify the source VLAN to monitor. The range is 1 to 4094 (excluding the RSPAN VLAN). Note A single session can include multiple sources (ports or VLANs), defined in a series of mands, but you cannot bine source ports and source VLANs in one session. (Optional) [, | ] Specify a series or range of interfaces. Enter a space before and after the ma。 enter a space before and after the hyphen. (Optional) Specify the direction of traffic to monitor. If you do not specify a traffic direction, the SPAN monitors both sent and received traffic. ? both—Monitor both received and sent traffic. This is the default. ? rx—Monitor received traffic. ? tx—Monitor sent traffic. Note You can use the monitor session session_number source mand multiple times to configure multiple source ports. Step 4 monitor session session_number destination {interface interfaceid [, | ] [encapsulation replicate]} Specify the SPAN session and the destination port (monitoring port). For session_number, specify the session number entered in step 3. Note For local SPAN, you must use the same session number for the source and destination interfaces. For interfaceid, specify the destination port. The destination interface must be a physical port。 it cannot be an EtherChannel, and it cannot be a VLAN. (Optional) [, | ] Specify a series or range of interfaces. Enter a space before and after the ma。 enter a space before and after the hyphen. (Optional) Enter encapsulation replicate to specify that the destination interface replicates the source interface encapsulation method. If not selected, the default is to send packets in native form (untagged). Note You can use monitor session session_number destination mand multiple times to configure multiple destination ports. Step 5 end Return to privileged EXEC mode. Step 6 show monitor [session session_number] show runningconfig Verify the configuration. Step 7 copy runningconfig startupconfig (Optional) Save the configuration in the configuration file. 舉例：通過交換機的第 2 號口監(jiān)控第 1 號口的流量 Switch(config) monitor session 1 source interface gigabitether0/1 Switch(config) monitor session 1 destination interface gigabitether0/2 Switch(config) end 刪除一個 span 會話 : Switch(config) no monitor session 1 source interface gigabitether0/1 Switch(config) end 以太通道端口組（ Ether Port Groups） 以太通道端口組提供 把多個交換機端口像一個交換端口對待。這些端口組為交換機之間或交換機和服務(wù)器之間提供一條單獨的高帶寬連接的邏輯端口。以太通道在一個通道中提供穿越鏈路的負(fù)載平衡。如果以太通道中的一個鏈路失效，流量會自動從失效鏈路轉(zhuǎn)移到被用鏈路。你可以把多干道端口加到一個邏輯的干道端口；把多訪問端口加到一個邏輯訪問端口；或者多隧道端口加到一個邏輯的隧道接口。絕大多數(shù)的協(xié)議能夠在單獨或是集合的接口上運行，并且不會意識到在端口組中的物理端口。除了 DTP、 CDP 和 PAgP，這些協(xié)議只能在物理接口上運行。 當(dāng)你配置一個以太通道，你創(chuàng)建一 個端口通道邏輯接口，并且指派一個接口給以太通道。對于三層接口，你人工創(chuàng)建該邏輯接口： Figure 331 Typical EtherChannel Configuration 舉例：把交換機 A， B的 1,2 號口添加到同一個組 5 里面 SwitchA configure terminal SwitchA (config) interface range gigabitether0/1 2 SwitchA (configifrange) switchport mode access SwitchA (configifrange) switchport access vlan 10 SwitchA (configifrange) channelgroup 5 mode ON Switch(configifrange) end SwitchB configure terminal SwitchB(config) interface range gigabitether0/1 2 SwitchB(configifrange) switchport
