System Requirements

The following are the minimum system requirements:

  • Memory: 4GB DDR4

  • Flash Storage: 4GB

Determining the Software Version

You can use the following commands to verify your software version:

  • For a consolidated package, use the show version command

  • For individual sub-packages, use the show version installed command

Installing a New Software Release

To install, obtain a Cisco IOS XE 16.x consolidated package (image) from Cisco.com. You can find software images at http://software.cisco.com/download/navigator.html. To run the router using individual sub-packages, you also need to first download the consolidated package and extract the individual sub-packages from a consolidated package.

For information about upgrading software, see the “Installing the Software” section in the Software Configuration Guide for the Cisco 1100 Series ISRs.

Feature Navigator

You can use Cisco Feature Navigator to find information about feature, platform, and software image support. To access Cisco Feature Navigator, go to http://www.cisco.com/go/cfn . An account on cisco.com is not required.

New Hardware and Software Features for Cisco 1100 Series ISRs Release 16.6.x

This section describes the new and modified features that are supported on the Cisco 1100 Series ISRs.

New Software Features in Cisco 1000 Series ISR Release Cisco IOS XE Everest 16.6.1

New Hardware Features in Cisco 1100 Series ISR Release 16.6.2

The following are the new hardware features in Cisco 1100 Series Integrated Service Routers in the 16.6.2 release:

  • Cisco 1100 Series Integrated Services Routers–The Cisco 1100 Series ISRs are fixed branched routers based on the Cisco IOS XE Everest 16.6.2 operating system, multi-core data plane. The two types of platforms of Cisco 1100 Series ISRs are High-End and Midrange service and enterprise platforms. The Cisco 1100 Series ISR Software Configuration Guide explains supported features such as Smart Licensing, VDSL2 and ADSL2/2+, WLAN, 4G LTE-Advanced, and so on.

    Cisco® 1100 Series Integrated Services Routers (ISRs) with Cisco IOS® XE Software combine Internet access, comprehensive security, and wireless services (LTE Advanced 3.0 Wireless WAN and Wireless LAN), are single high-performance devices that are easy to deploy and manage. They are well suited for deployment as customer premises equipment (CPE) in enterprise branch offices, and in service provider managed-service environments.

New Software Features in Cisco 1100 Series ISR Release 16.6.2

The following features are supported by the Cisco 1100 Series Integrated Services Routers for Cisco IOS XE Everest 16.6.2:

  • Encrypted Traffic Analytics

    For detailed information, see the following Cisco documents:

    https://www.cisco.com/c/en/us/td/docs/routers/access/1100/software/configuration/xe-16-6/cisco_1100_series_swcfg_xe_16_6_x/encypt_traffic_anytcs.html

    https://www.cisco.com/c/dam/en/us/td/docs/solutions/CVD/Campus/CVD-Encrypted-Traffic-Analytics-Deployment-Guide-2017DEC.pdf

  • Smart Licensing - Smart Licensing Client feature is a standardized licensing platform that simplifies the Cisco software experience and helps you to understand how Cisco software is used across your network. Smart Licensing is the next generation licensing platform for all Cisco software products.

  • VDSL2 and ADSL 2/2+ - VDSL2 and ADSL2/2+ Cisco® C1100 Series Integrated Services Router provide highly reliable WAN connections for remote sites. These interfaces offer cost-effective virtualized WAN connections in both point-to-point and point-to-multipoint designs.

  • Wireless Devices - Wireless devices (commonly configured as access points ) provide a secure, affordable, and easy-to-use wireless LAN solution that combines mobility and flexibility with the enterprise-class features required by networking professionals.

  • Cisco 4G LTE Advanced - Cisco 4G LTE-Advanced support the following major features: Global Positioning System (GPS) and National Marine Electronics Association (NMEA) streaming, Short Message Service (SMS), 3G/4G Simple Network Management Protocol (SNMP) MIB, SIM lock and unlock capabilities, Dual SIM, Auto SIM, NeMo, Public Land Mobile Network (PLMN) selection, IPv6, Multiple PDN, and LTE Link Recovery.

  • Process Health Monitoring - Processes should provide monitoring and notification of their status/health to ensure correct operation. When a process fails, a syslog error message is displayed and either the process is restarted or the router is rebooted. A syslog error message is displayed when a monitor detects that a process is stuck or has crashed. If the process can be restarted, it is restarted; else, the router is restarted.

  • Environmental Monitoring - The router provides a robust environment-monitoring system with several sensors that monitor the system temperatures. The following are some of the key functions of the environmental monitoring system: Monitoring temperature of CPUs, Motherboard, and Wifi, Recording abnormal events and generating notifications, Monitoring Simple Network Management Protocol (SNMP) traps, Generating and collecting Onboard Failure Logging (OBFL) data, Sending call home event notifications, Logging system error messages, and Displaying present settings and status.

  • SFP Auto-Failover - When the media-type is not configured, the Auto-Detect feature is enabled by default. The Auto-Detect feature automatically detects the media that is connected and links up. If both the media are connected, whichever media comes up first is linked.

  • Cellular IPv6 Address - IPv6 addresses are represented as a series of 16-bit hexadecimal fields separated by colons (:) in the format: x:x:x:x:x:x:x:x. Following are two examples of IPv6 addresses: 2001:CDBA:0000:0000:0000:0000:3257:9652 and 2001:CDBA::3257:9652 (zeros can be omitted).

Entering the Configuration Commands Manually

To enter the Cisco IOS commands manually, complete the following steps:

Before you begin

If you do not want to use the factory default configuration because the router already has a configuration, or for any other reason, you can use the procedure in this section to add each required command to the configuration.

Procedure


Step 1

Log on to the router through the Console port or through an Ethernet port.

Step 2

If you use the Console port, and no running configuration is present in the router, the Setup command Facility starts automatically, and displays the following text:

--- System Configuration Dialog ---
 
Continue with configuration dialog? [yes/no]:

Enter no so that you can enter Cisco IOS CLI commands directly.

If the Setup Command Facility does not start automatically, a running configuration is present, and you should go to the next step.

Step 3

When the router displays the user EXEC mode prompt, enter the enable command, and the enable password, if one is configured, as shown in the following example:

Router> enable
password password
Step 4

Enter config mode by entering the configure terminal command, as shown in the following example.

Router> config terminal
Router(config)#
Step 5

Using the command syntax shown, create a user account with privilege level 15.

Step 6

If no router interface is configured with an IP address, configure one so that you can access the router over the network. The following example shows the interface Fast Ethernet 0 configured.

Router(config)# int FastEthernet0
Router(config-if)# ip address 10.10.10.1 255.255.255.248
Router(config-if)# no shutdown
Router(config-if)# exit
Step 7

Configure the router as an http server for nonsecure communication, or as an https server for secure communication. To configure the router as an http server, enter the ip http server command shown in the example:

Router(config)# ip http secure-server
Step 8

Configure the router for local authentication, by entering the ip http authentication local command, as shown in the example:

Router(config)# ip http authentication local
Step 9

Configure the vty lines for privilege level 15. For nonsecure access, enter the transport input telnet command. For secure access, enter the transport input telnet ssh command. An example of these commands follows:

Router(config)# line vty 0 4
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# exit
Router(config)# line vty 5 15
Router(config-line)# privilege level 15
Router(config-line)# login local
Router(config-line)# transport input telnet
Router(config-line)# transport output telnet
Router(config-line)# transport input telnet ssh
Router(config-line)# transport output telnet ssh
Router(config-line)# end
