Basic Router Configuration

This chapter provides procedures for configuring the basic parameters of your Cisco router, including global parameter settings, routing protocols, interfaces, and command-line access.

Note : Individual router models may not support every feature described in this guide. Features that are not supported by a particular router are indicated whenever possible.

This chapter includes configuration examples and verification steps, as available.

Default Configuration

When you first boot up your Cisco router, some basic configuration has already been performed. All of the LAN and WAN interfaces have been created, and the console and vty ports are configured.

Bootstrap Sequence

The following graphic illustrates how the IR807 goes through its bootup process.

Example:

Router(config)# enable secret cr1ny5ho

Specifies an encrypted password to prevent unauthorized access to the router.

4

no ip domain-lookup

Example:

Router(config)# no ip domain-lookup

Disables the router from translating unfamiliar words (typos) into IP addresses.

No Service Password Recovery

The No Service Password-Recovery is a Cisco IOS Platform independent feature which is available in Cisco IOS classic devices.

The following events will cause the router to go into rommon mode as standard behavior:

  • Manual boot setting was done in IOS mode

  • If flash is corrupt


Note
Ensure a valid Cisco IOS image is present in flash before enabling this feature.

For complete configuration information, refer to the following:https://www.cisco.com/c/en/us/td/docs/ios-xml/ios/sec_usr_cfg/configuration/15-mt/sec-usr-cfg-15-mt-book/sec-no-svc-pw-recvry.html

Configuring WAN Interfaces

Configure the WAN interface for your router using one of the following as appropriate:

Configuring a Fast Ethernet Layer-3 Interface

To configure the Fast Ethernet interface, perform these steps, beginning in global configuration mode:

SUMMARY STEPS

  1. interface type number hostname name
  2. ip address ip-address mask
  3. no shutdown
  4. exit

DETAILED STEPS

Step

Command or Action

Purpose

1

interface type number

Example:

Router(config)# interface fastethernet 0

Router(config-if)#

Enters the configuration mode for a Fast Ethernet WAN interface on the router.

2

ip address ip-address mask

Example:

Router(config)# ip address 192.168.1.5 255.255.255.0

Router(config-if)#

Sets the IP address and subnet mask for the specified Fast Ethernet interface.

3

no shutdown

Example:

Router(config-if)# no shutdown

Enables the Ethernet interface, changing its state from administratively down to administratively up.

4

exit

Example:

Router(config-if)# exit

Exits configuration mode for the Fast Ethernet interface and returns to global configuration mode.

Configuring the Cellular Wireless WAN Interface

The IR807 series provides a wireless interface supporting 4G/LTE networks.

To configure the cellular wireless interface, follow these guidelines and procedures:

Prerequisites for Configuring the Wireless Interface

The following are prerequisites to configuring the wireless interface:

  • You must have wireless service from a carrier, and you must have network coverage where your router will be physically placed.
  • You must subscribe to a service plan with a wireless service provider.
  • You must check your LEDs for signal strength.

Restrictions for Configuring the Cellular Wireless Interface

The following restrictions apply to configuring the Cisco wireless interface:

  • A data connection can be originated only by the wireless interface. Remote dial-in is not supported.
  • Because of the shared nature of wireless communications, the experienced throughput varies depending on the number of active users or the amount of congestion in a given network.
  • Cellular networks have higher latency than wired networks. Latency rates depend on the technology and carrier. Latency may be higher when there is network congestion.
  • VoIP is not currently supported.
  • Any restrictions that are part of the terms of service from your carrier also apply to the Cisco wireless interface.

Configuring Router for Image and Configuration Recovery Using Push Button

A push button feature is available on the IR807. The reset button on the front panel of the router enables this feature.

Perform the following steps to use this feature:

  1. Unplug power.
  2. Press the reset button on the front panel of the router.
  3. Power up the system while holding down the reset button. The system LED blinks four times indicating that the router has accepted the button push.

Using this button takes effect only during ROMMON initialization. During a warm reboot, pressing this button has no impact on performance. The following table shows the high level functionality when the button is pushed during ROMMON initialization.

ROMMON Behavior

IOS Behavior

  • Boots using default baud rate.
  • Performs auto-boot.
  • Loads the *.default image if available on compact flash Note If no *.default image is available the ROMMON will boot up with the first Cisco IOS image on flash.

Examples of names for default images:

ir800l-universalk9-mz.SPA.157-3.M0a.default

If the configuration named customer-config.SN (SN is the serial number of the device) is available in nvram storage or flash storage, IOS will perform a backup of the original configuration and will boot up using this configuration.

Note : You can only have one configuration file with customer-config.SN option. Having more than one file will result in uncertain operational behavior.

Use the show platform command to display the current bootup mode for the router. The following sections show sample outputs when the button is not pushed and when the button is pushed.

Output When Button Is Not Pushed: Example


router# show platform boot-record
Platform Config Boot Record :
============================
Configuration Register at boot time : 0x0
Reset Button Status at Boot Time    : Not Pressed

Output When Button Is Not Pushed: Example


router# show platform boot-record
Platform Config Boot Record :
============================
Configuration Register at boot time : 0x0
Reset Button Status at Boot Time    : Pressed
Golden config file at location      : flash:/pnp-reset-config.cfg
Config Recovery Status              : Ok

Configuring a Loopback Interface

The loopback interface acts as a placeholder for the static IP address and provides default routing information.

Perform these steps to configure a loopback interface, beginning in global configuration mode

SUMMARY STEPS

  1. interface type number
  2. ip address ip-address mask
  3. exit

DETAILED STEPS

Step

Command or Action

Purpose

1

interface type number

Example:

Router(config)# interface Loopback 0

Router(config-if)#

Enters configuration mode for the loopback interface.

2

Example:

Router(config-if)# ip address 192.168.1.1 255.255.255.0

Router(config-if)#

Sets the IP address and subnet mask for the loopback interface.

3

exit

Example:

Router(config-if)# exit

Router(config)#

Exits configuration mode for the loopback interface and returns to global configuration mode.
