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

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> 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

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 Module1 Channel-id1 module Module2 Channel-id2

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.

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 "System Error Messages for the connect Command" section, the following commands can help troubleshoot NME connections:

show connection all

show connection id connection-id

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 "SFP in use with an NME in Module Interconnection."

Establishing a Connection Between Two GE NME Slots

Follow these steps to establish a connection between two GE NMEs.

SUMMARY STEPS

1. enable

2. configure terminal

3. connect connection-name module Module1 Channel-id1 module Module2 Channel-id2

Creates the connection identified as connection-name between the GE NME slot Module1 the GE NME slot Module2.

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 module configuration mode.

Step 4 

exit

Example:

Router(config-module-conn)# exit

Exits module configuration mode. After exiting module configuration mode, the connection establishment begins.

Examples

The example below shows the creation of a connection between a GE interface on NME slot 2 and a GE interface on NME slot 4:

Router(config)# connect connection1 module GigabitEthernet2/0 0 module 
GigabitEthernet4/0 0
Router(config-module-conn)# exit

Troubleshooting Tips

In addition to the system error messages listed in the "System Error Messages for the connect Command" section, the following commands can help troubleshoot NME connections:

show connection all

show connection id connection-id

where connection-id is in the range of 0 to 10000

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 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.

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.

Table 3 Connection Configuration Mode Commands

Command
Description

default
