Cisco SM-X Layer 2/3 EtherSwitch Service Module Configuration Guide for Cisco 4451-X ISR
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.
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.
Until the client is authenticated, IEEE 802.1x access control allows only Extensible Authentication
Protocol over LAN (EAPOL), Cisco Discovery Protocol (CDP), and Spanning Tree Protocol (STP)
traffic through the port to which the client is connected. After authentication, normal traffic can pass
through the port. See

Licensing and Software Activation
The Cisco SM-X Layer 2/3 ESM utilizes the Cisco licensing software activation mechanism for different
levels of technology software packages. This mechanism is referred to as technology package licensing and
leverages the universal technology package based licensing solution. A universal image containing all levels
of a software package is loaded on your Cisco SM-X Layer 2/3 ESM. During startup, the Cisco SM-X Layer
2/3 ESM determines the license according to the license boot level or license priority and loads the corre-
sponding software features.
The Cisco SM-X Layer 2/3 ESM has a right to use (RTU) license, also known as honor-based license.
The RTU license on Cisco SM-X Layer 2/3 ESM supports the following three feature sets:

The RTU license on Cisco SM-X Layer 2/3 ESM supports the following three feature sets:
•
LAN Base: Enterprise access Layer 2 switching features
•
IP Base: Enterprise access Layer 3 switching features
•
IP Services: Advanced Layer 3 switching (IPv4 and IPv6) features
Installing and Applying an RTU License on a Switch
To apply an RTU license on a switch, follow these steps:
Step 1
Upgrade from one license level to another by using the Cisco sales ordering tool to purchase the license.
You will receive an e-mail or paper confirmation that grants you permission to install and activate the
license on your switch.
You will receive an e-mail or paper confirmation that grants you permission to install and activate the
license on your switch.
Step 2
If you get a license file, use license install stored-location-url command to install the license. Accept
the end-user license agreement when prompted and restart the device to enable the new feature set.
the end-user license agreement when prompted and restart the device to enable the new feature set.
Step 3
Apply the license by entering the appropriate commands on your switch. If you are upgrading a license
on a switch, use license right-to-use activate license-level command to activate the higher license. If
you are moving a license from one switch to another, use the license right-to-use deactivate
license-level command to deactivate the license on the first switch and the activation command on the
second switch.

you are moving a license from one switch to another, use the license right-to-use deactivate
license-level command to deactivate the license on the first switch and the activation command on the
second switch.
Step 4
Read and accept the End User License Agreement (EULA).
Step 5
Use show license command to check the license status.
Step 6
Configure the license boot level to the license you want to use by entering (config)#license boot level
license-level command and then save the configuration using write memory command.

Step 7
Use show version command to check whether the next reload license is correctly configured.
Step 8
Reboot the switch to boot with the highest available license.
