　　Restrictions for Cisco High-Speed Intrachassis Module Interconnect (HIMI)
　　Connections can be only established as follows:
　　? Between the GE port in an installed small-form-factor pluggable (SFP) module on the Cisco 3825 and Cisco 3845 routers
　　? Between GE interfaces in NME slots 1 and 2 on the Cisco 3825 router
　　? Between GE interfaces in NME slots 2 and 4 on the Cisco 3845 router

　　Note A module interconnection between the GE port on an SFP module and an NME slot or an NME-to-NME cross-connection is permitted at any given time, but both types of connections cannot exist at the same time.

　　Note Connections between the onboard RJ-45 GE ports and NME slots are not supported.
　　Information About Cisco High-Speed Intrachassis Module Interconnect
　　To configure HIMI connections, you should understand the following concepts:
　　? Connection Configuration Mode
　　? System Error Messages for the connect Command
　　Connection Configuration Mode
　　Cisco 3825 and Cisco 3845 routers provide support for interconnecting NMEs using the router HIMI. This feature provides the new connect connection-name module Module1 Channel-id1 module Module2 Channel-id2 command for the Cisco IOS command line interface (CLI) that creates an interconnection between GE modules using the HIMI. Connections can be made between the onboard GE port in an SFP module and an NME or between two NMEs.
　　If the new connect command is successfully executed, the router enters connection configuration mode, which is designated by the "config-module-conn" prompt. Once the router is in connection configuration mode, the commands shown in Table 1 can be issued.
　　Table 1 Connection Configuration Mode Commands
　　Command
　　Description
　　default
　　Sets a command to its default values. Has no effect on the connect command functionality.
　　exit
　　Exits connection configuration mode. After you exit connection configuration mode, the actual connection establishment phase starts.
　　shutdown
　　Shuts down the connection. This command effectively deactivates the connection.
　　no
　　Negates a command or sets it to default. The no shutdown command reactivates a previously shut down connection.
　　To establish a connection, after entering connection configuration mode, issue the exit command to return to configuration mode. The connection will be established after you leave connection configuration mode.

　　System Error Messages for the connect Command
　　The following informational error messages appear on the console when something goes wrong during connection establishment or deletion phases:

　　How to Configure HIMI Connections
　　This section contains the following procedures:
　　? Establishing a Connection Between an SFP GE Port and a GE NME Slot
　　? Establishing a Connection Between Two GE NME Slots
　　? Deactivating a HIMI Connection
　　1.建立SFP GE和GE NME的互连配置命令
　　Establishing a Connection Between an SFP GE Port and a GE NME Slot
　　Follow these steps to establish a connection between an SFP module GE port and a GE NME.
　　SUMMARY STEPS
　　1. enable
　　2. configure terminal
　　3. interface gigabitethernet 0/0
　　4. media-type rj45
　　5. exit
　　6. connect connection-name module Module1 Channel-id1 module Module2 Channel-id2
　　7. exit
　　DETAILED STEPS
　　Command or Action
　　Purpose
　　Step 1
　　enable
　　Example:
　　Router&gt; enable
　　Enables privileged EXEC mode.
　　Enter your password if prompted.
　　Step 2
　　configure terminal
　　Example:
　　Router# configure terminal
　　Enters global configuration mode.
　　Step 3
　　interface gigabitethernet 0/0
　　Example:
　　Router(config)# interface gigabitethernet 0/0
　　Enters interface configuration mode on the Gigabit Ethernet 0/0 interface.
　　Step 4
　　media-type rj45
　　Example:
　　Router(config-if)# media-type rj45
　　Ge on SFP互连必须配置RJ45模式
　　Sets the media type on the Gigabit Ethernet 0/0 interface to RJ-45.
　　Note In order to create a connection to the GE port on the SFP module, the media type on the GE interface must be RJ-45. A connection cannot be established if the media type is SFP.
　　Step 5
　　exit
　　Example:
　　Router(config-if)# exit
　　Exits interface configuration mode.
　　Step 6
　　connect connection-name module Module1Channel-id1 module Module2 Channel-id2
　　Example:
　　Router(config)# connect connection1 module GigabitEthernet0/0 0 module GigabitEthernet4/0 0

　　Creates the connection>　　Note Since this procedure creates a connection between the SFP GE port and an NME, either Module1 or Module2 must be GigabitEthernet0/0.
　　Note On Cisco 3825 and Cisco 3845 routers, only one channel per slot is defined. Therefore, the Channel-id1 and Channel-id2 variables must always have a value of 0.
　　After this command is issued, the router enters connection configuration mode.
　　Step 7
　　exit
　　Example:
　　Router(config-module-conn)# exit
　　Exits module configuration mode. After you exit connection configuration mode, the connection establishment begins.
　　Examples
　　The example below shows the creation of a connection between the SFP GE port and a GE interface on NME slot 4:
　　Router(config)# interface gigabitethernet 0/0
　　Router(config-if)# media-type rj45
　　Router(config)# connect connection1 module GigabitEthernet0/0 0 module GigabitEthernet4/0 0
　　Router(config-module-conn)# exit
　　Troubleshooting Tips
　　In addition to the system error messages listed in the &quot;System Error Messages for the connect Command&quot; section, the following commands can help troubleshoot NME connections:
　　? show connection all

　　? show connection>　　where connection-id is in the range of 0 to 10000
　　? show connection name connection-name
　　? show interfaces gigabitethernet 0/0—If a connection has successfully been established between the SFP module and an NME slot, this command will display the output &quot;SFP in use with an NME in Module Interconnection.&quot;
