Cisco High-Speed Intrachassis Module Interconnect (HIMI)
Cisco 3900 series and Cisco 2900 series routers use Cisco High-Speed Intrachassis Module Interconnect
(HIMI) to support SM-to-SM or SM-to-ISM communication through the MGF.
Use the connect connection-name module Module1 Channel-id1 module Module2 Channel-id2
command to establish a maximum of two HIMI connections on the Cisco 3900 series ISR routers and
one HIMI connection on Cisco 2900 series andCisco 1900 series ISRs. Module 1 and Module 2 are the
slot/port of the two modules. The Channel-id1 and Channel-id2 variables must always have a value of 0.
When two modules are configured in a HIMI connection, the modules cannot send traffic to any other
module except its HIMI-dedicated partner.
See Cisco High-Speed Intrachassis Module Interconnect (HIMI) Configuration Guide at Cisco.com for
detailed configuration instructions,
http://www.cisco.com/en/US/docs/ios/12_4/12_4_mainline/srdesfm1.html.
Note See the module documentation to validate HIMI support.
Using HIMI for VLAN Traffic Flows
For HIMI configurations, the port-level VLAN memberships are ignored on the Multi-Gigabit Fabric
(MGF). Use the connect connection-name module module1 vlan-id module module2 command to
redirect VLAN traffic flows from SM-to-SM or SM-to-ISM connections on the MGF.
The following two modules, as well as others, support VLAN traffic redirection:
• Cisco Etherswitch service module
• Cisco Services Ready Engine internal service module (ISM-SRE)
Note See the module documentation to validate HIMI support.
