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

|
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.

Example:
Router(config)# connect connection1 module
GigabitEthernet0/0 0 module
GigabitEthernet4/0 0
|
Creates the connection identified as connection-name between the GE module Module1 and the GE module Module2.
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.

Configuration Examples for Cisco High-Speed Intrachassis Module Interconnect
This section contains the following examples:
•Sample Connection Between an SFP GE Port and a GE NME Slot
•Sample Connection Between Two GE NME Slots
Sample Connection Between an SFP GE Port and a GE NME Slot
The following sample output from a router configuration file shows a connection between the GE port on an SFP module and a GE slot on an NME:
Router# show running-config
interface GigabitEthernet0/0
mac-address 0002.0022.2222
ip address 192.168.0.2 255.255.255.0

ip classless
ip route 10.10.0.0 255.255.0.0 1.3.0.1
!
ip http server
!
connect connection-1 module GigabitEthernet0/0 0 module GigabitEthernet4/0 0
.
Note If the speed and duplex setting for g0/0 in SFP mode is speed=1000 and duplex=full, autonegotiation is in forced mode and autonegotation is turned off. For all other mode settings of speed or duplex for SFP, autonegotiation is turned on.
If speed=1000 and duplex=full modes are specified for both g0/0 and g0/1 interfaces in copper mode (RJ-45), autonegotiation is still turned on. This is considered to be in forced mode for speed=1000. This occurence is per the Annex 28D.5 extensions required for clause 40 (1000-BASE-T) IEEE 802.3.
When the speed and duplex modes are forced for 10/100, and full or half modes are forced for g0/0 and g0/1 interfaces, autonegotiation is turned off. If the interfaces are not in forced mode for 10/100 speeds, then autonegotation will be turned on.
Sample Connection Between Two GE NME Slots
The following sample output from a router configuration file shows a connection between two GE slots on an NME:
Router# show running-config

Modified Commands
•show connection
connect (module)
To create a connection between two Gigabit Ethernet (GE) enhanced network modules (ENMs) or between the GE port on an installed small-form-factor-pluggable (SFP) module and a GE ENM on a Cisco 3800 series router, use the connect command in global configuration mode. To deactivate a connection between two GE modules on a Cisco 3800 series router, use the no form of this command.
connect connection-name module module1 channel-id1 module module2 channel-id2
no connect connection-name
Syntax Description
connection-name
|
Unique name for this connection.
|
module module1 channel-id1
|
First of the two GE interfaces on the router between which a connection will be created.
•Use the module1 argument to identify the GE port number. Use the syntax GigabitEthernetslot/port, where slot is the slot number in which the ENM resides, or 0 for the router onboard SFP GE port, and port is either the ENM port number or 0 for the router onboard SFP GE port.
The following interfaces are valid:
–On the Cisco 3825 and Cisco 3845 routers, the GE port in an installed SFP module
–On the Cisco 3825 router, GE interfaces in ENM slots 1 and 2
–On the Cisco 3845 router, GE interfaces in ENM slots 2 and 4
•Use the channel-id1 argument to indicate the channel identifier on the interface slots of module1. On Cisco 3800 series routers, there is only one channel identifier, so this value must be 0.
|
module module2 channel-id2
|
Second of the two GE interfaces on the router between which a connection will be created.
•Use the module2 argument to identify the GE port number. Use the syntax GigabitEthernetslot/port, where slot is the slot number in which the ENM resides, or 0 for the onboard SFP GE port, and port is either the ENM port number or 0 for the onboard SFP GE port.
The following interfaces are valid:
–On the Cisco 3825 and Cisco 3845 routers, the GE port in an installed SFP module
–On the Cisco 3825 router, GE interfaces in ENM slots 1 and 2
–On the Cisco 3845 router, GE interfaces in ENM slots 2 and 4
•Use the channel-id2 argument to indicate the channel identifier on the interface slots of module2. On Cisco 3800 series routers, there is only one channel identifier, so this value must be 0.

Usage Guidelines
To create a connection between two GE modules on a Cisco 3800 series router using the High-Speed Intrachassis Module Interconnect (HIMI) feature, use the connect connection-name module module1 channel-id1 module module2 channel-id2 command in global configuration mode.
Connections can be established only as follows:
•Between the GE ports in an installed SFP module on the Cisco 3825 and Cisco 3845 routers
Note The GE interface on the SFP port must be configured as media type "rj45" to establish a connection.
•Between GE interfaces in ENM slots 1 and 2 on the Cisco 3825 router
•Between GE interfaces in ENM slots 2 and 4 on the Cisco 3845 router
Note A module interconnection between the GE port on an SFP module and an ENM slot or an ENM-to-ENM 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 ENM slots are not supported.
If the 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 3 can be issued.
