Feature Availability
Unless otherwise indicated, all features and configurations in this guide are supported beginning with release 15.2(2)EA
for the IE-4000, 15.2(2)EB for the IE-5000 and in release 15.2(4)EC for the IE-4010. Where new features or support for
existing features was added after these releases, detailed release information will be indicated in the Feature History
Table for that feature.
Feature availability varies depending on your license. For more information about licenses and available features, refer to
the datasheet:
Feature Software Licensing
Software Licensing is now simplified with the introduction of right-to-use (RTU) licensing. This allows you to order and
activate a specific license type and level via command line. Uploading an extra license file is no longer necessary.
Note: Upgrading to the IP Services feature set requires the purchase of one of the following licenses (product IDs listed):
The IE-5000 uses "L-IE5000-RTU=" and IE-4000 and IE-4010 use "L-IE4000-RTU=" to upgrade to IP Services.
Right to Use Licenses
The introduction of right-to-use (RTU) licensing allows you to order and activate a specific license type and level via
command line. Uploading an extra license file is no longer necessary.

Management Options
An embedded Device Manager—Device Manager is a GUI application that is integrated in the software image. You
use it to configure and to monitor a single switch. For more information about Device Manager, see the switch online
help.
Network Assistant—Network Assistant is a network management application that can be downloaded from
Cisco.com. You use it to manage a single switch, a cluster of switches, or a community of devices. For more
information about Network Assistant, see Getting Started with Cisco Network Assistant, available at
software.cisco.com/download/.
Prime Infrastructure—Cisco Prime Infrastructure simplifies the management of wireless and wired networks. It offers
Day 0 and 1 provisioning, as well as Day N assurance from the branch to the data center. We call it One Management.
With this single view and point of control, you can reap the benefits of One Management across both network and
compute.

Configuration Overview
Default Settings After Initial Switch Configuration
CLI—The Cisco IOS software supports desktop- and multilayer-switching features. You can access the CLI either by
connecting your management station directly to the switch console port or by using Telnet from a remote
management station.
SNMP—SNMP management applications such as CiscoWorks2000 LAN Management Suite (LMS) and HP OpenView.
You can manage from an SNMP-compatible management station that is running platforms such as HP OpenView or
SunNet Manager. The switch supports a comprehensive set of MIB extensions and four remote monitoring (RMON)
groups. For more information about using SNMP, see Configuring SNMP, page 557
Cisco IOS Configuration Engine (previously known as the Cisco IOS CNS agent)—Configuration service automates
the deployment and management of network devices and services. You can automate initial configurations and
configuration updates by generating switch-specific configuration changes, sending them to the switch, executing
the configuration change, and logging the results.
For more information about CNS, see Configuring Cisco IOS Configuration Engine, page 79
Industrial Application
CIP—Common Industrial Protocol (CIP) is a peer-to-peer application protocol that provides application level
connections between the switch and industrial devices such as I/O controllers, sensors, relays, and so forth.You can
manage the switch using RSlogix/RSlinx then monitor the CIP functionality via IOS command lines or Web based
Device Manager.
Profinet Version 2—Support for PROFINET IO, a modular communication framework for distributed automation
applications. The embedded Profinet GSD file allows user to bring up Cisco IE switch using Siemens STEP7 or TIA
Portal software then monitor the functionality via command line or Web based Device Manger.
Default Settings After Initial Switch Configuration
The switch is designed for plug-and-play operation, requiring only that you assign basic IP information to the switch and
connect it to the other devices in your network. If you have specific network needs, you can change the interface-specific
and system-wide settings.
Note: For information about assigning an IP address by using the CLI-based setup program, see the hardware installation
guide.
If you do not configure the switch at all, the switch operates with these default settings:
Note: For more information about the following default settings, see the corresponding sections of this guide.
Default switch IP address, subnet mask, and default gateway is 0.0.0.0.
Default domain name is not configured.
DHCP client is enabled, the DHCP server is enabled, and the DHCP relay agent is enabled.
Switch cluster is disabled.
No passwords are defined.
System name and prompt is Switch.
NTP is enabled.
DNS is enabled.
TACACS+ is disabled.
