Internal Port Mapping
below displays the internal port mapping between the Cisco SM-X Layer 2/3 ESM and the
Cisco 4451-X ISR. The variable “x” indicates the slot number where the Cisco SM-X-ES3-16-P, Cisco
SM-X-ES3-24-P and Cisco SM-X-ES3D-48-P SKUs of the module are inserted on the Cisco 4451-X
ISR router.

Managing MGF Ports for Layer 2 Features
The Cisco SM-X Layer 2/3 ESM enables the backplane Ethernet interfaces using the interface
Ethernet-internal slot /0/[0|1] command to ensure proper management of Layer 2 switching properties
such as access, trunk, and dynamic mode of its two MGF ports, GE0 and GE1. The MGF port uses
certain switchport commands to perform different functions for different modes. For example, access
mode is used for end devices; trunk mode is used for lines between switches and other lines that send
multiple VLANs over a single connection, and dynamic mode automatically detects what kind of device
is connected and initiates its port accordingly.

Enabling Layer-3 Features under Ethernet-internal Interface
The following examples show the Layer 3 feature configuration. In
, you should configure ip
nat inside under the BDI10 instead of configuring it under interface Ethernet-internal1/0/0.
