Cisco SM-X Layer 2/3 EtherSwitch Service

Module Configuration Guide for Cisco 4451-X ISR

April 2, 2014

The Cisco SM-X Layer 2/3 EtherSwitch Service Module (Cisco SM-X Layer 2/3 ESM) integrates the

Layer 2 and Layer 3 switching features and provides the Cisco 4451-X ISR the ability to use the Cisco

SM-X Layer 2/3 ESM as an independent Layer 3 switch when running the Cisco IOS software.

The Cisco SM-X Layer 2/3 ESMs also provide a 1-Gbps connection to the multigigabit fabric (MGF)

for intermodule communication without burdening your router’s CPU.

The Cisco SM-X Layer 2/3 ESMs are capable of providing up to 30 watts of power per port with the

robust Power over Ethernet Plus (PoE+) feature, along with IEEE 802.3AE Media Access Control

Security (MACSec) port-based, hop-to-hop, encryption, and Cisco TrustSec (CTS) which work on

multiple router families.

The following is the feature history for the Cisco SM-X Layer 2/3 ESM:

Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide for Cisco 4451-X ISR Software Features IEEE 802.1x Protocol The IEEE 802.1x standard defines a client/server-based access control and authentication protocol that prevents clients from connecting to a LAN through publicly accessible ports unless they are authenticated. The authentication server authenticates each client connected to a port before making available any services offered by the router or the LAN.

Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide for Cisco 4451-X ISR Software Features Power over Ethernet (Plus) Features The Cisco SM-X Layer 2/3 ESM is capable of providing power to connected Cisco pre-standard and IEEE 802.3af-compliant powered devices (PDs) from Power over Ethernet (PoE)-capable ports when the switch detects that there is no power on the circuit. The ESM supports IEEE 802.3at (PoE+), which increases the available power for PDs from 15.4 W to 30 W per port.

Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide for Cisco 4451-X ISR Software Features You can choose to gracefully power down your Cisco SM-X Layer 2/3 ESM before removing it from router. This type of OIR is also known as managed OIR or soft OIR. The managed OIR feature allows you to stop the power supply to your module using the hw-module subslot [stop] command and remove the module from one of the subslots while other active modules remain installed on the router.
