Feature Information
New Modules and
Interface Cards
Cisco 3900 series, 2900 series, and 1900 series ISRs introduce the
following new modules and interface cards, which are inserted in the
following new router slots:
• EHWIC
• PVDM3
• ISM

Note See the router’s product page at Cisco.com for a complete list of
supported modules and interfaces.
Multi-Gigabit Fabric
Communication
Cisco 3900 series, Cisco 2900 series, and Cisco 1900 series ISRs use a
MGF
4
for the new modules and interface cards to inter-communicate on
the router. Legacy modules that support Cisco HIMI
5
also support MGF
to inter-communicate on the router. Next generation module drivers
integrate with the MGF to perform port configurations, configure packet
flow, and control traffic buffering. All configurations are performed from
the module-side, which may or may not lead to changes on the MGF. For
more information, see the “Configuring Multi-Gigabit Fabric
Communication” section on page 211.
