Using the Cisco IOS CLI to Perform Initial Configuration
This section contains the following procedures:
Configuring the Router Hostname
The hostname is used in CLI prompts and default configuration filenames. If you do not configure the router hostname, the router uses the factory-assigned default hostname “Router.”
Do not expect case sensitivity to be preserved in the hostname. Uppercase and lowercase characters are treated identically by many Internet software applications. Conventions dictate that computer names appear in all lowercase characters. For more information, see RFC 1178, Choosing a Name for Your Computer.
The name must also follow the rules for ARPANET hostnames. They must start with a letter, end with a letter or digit, and have only letters, digits, and hyphens as interior characters. Names must be 63 characters or fewer. For more information, see RFC 1035, Domain Names—Implementation and Specification.

Configuring the Console Idle Privileged EXEC Timeout
This section describes how to configure the console line’s idle privileged EXEC timeout. By default, the privileged EXEC command interpreter waits for 10 minutes to detect user input before timing out.
When you configure the console line, you can also set communication parameters, specify autobaud connections, and configure terminal operating parameters for the terminal that you are using. For more information on configuring the console line, see Cisco IOS Configuration Fundamentals and Network Management Configuration Guide. In particular, see the “Configuring Operating Characteristics for Terminals” and “Troubleshooting and Fault Management” chapters.
SUMMARY STEPS

2. configure terminal
3. line console 0
4. exec-timeout minutes [ seconds ]
5. end
6. show running-config
DETAILED STEPS
|
|
|
Step 1 |
enable
Router> enable |
Enables privileged EXEC mode.
- Enter your password if prompted.
|
Step 2 |
configure terminal
Router# configure terminal |
Enters global configuration mode. |
Step 3 |
line console 0
Router(config)# line console 0 |
Configures the console line and starts the line configuration command collection mode. |
Step 4 |
exec-timeout minutes [ seconds ]
Router(config-line)# exec-timeout 0 0 |
Sets the idle privileged EXEC timeout, which is the interval that the privileged EXEC command interpreter waits until user input is detected.
- The example shows how to specify no timeout. Setting the exec-timeout value to 0 will cause the router to never log out once logged in. This could have security implications if you leave the console without manually logging out using the disable command.

Router(config)# end |
Returns to privileged EXEC mode. |
Step 6 |
show running-config
Router(config)# show running-config |

Specifying a Default Route or Gateway of Last Resort
This section describes how to specify a default route with IP routing enabled. For alternative methods of specifying a default route, see the Configuring a Gateway of Last Resort Using IP Commands tech note.
The Cisco IOS software uses the gateway (router) of last resort if it does not have a better packet route and if the destination is not a connected network. This section describes how to select a network as a default route (a candidate route for computing the gateway of last resort). The way in which routing protocols propagate the default route information varies for each protocol.
For comprehensive configuration information about IP routing and IP routing protocols, see the Cisco IOS IP Addressing Services Configuration Guide, Release 15.0. In particular, see the “ Configuring IPv4 Addresses ” chapter.
IP Routing
You can configure integrated routing and bridging (IRB) so the router can route and bridge simultaneously. The router will act as an IP host on the network whether routing is enabled or not. For more information about IRB, see Integrated Routing and Bridging (IRB).
IP routing is automatically enabled in the Cisco IOS software. When IP routing is configured, the system uses a configured or learned route to forward packets, including a configured default route.
Note This task section does not apply when IP routing is disabled. To specify a default route when IP routing is disabled, refer to Configuring a Gateway of Last Resort Using IP Commands.
Default Routes
A router might not be able to determine the routes to all other networks. To provide complete routing capability, the common practice is to use some routers as smart routers and give the remaining routers default routes to the smart router. (Smart routers have routing table information for the entire internetwork.) These default routes can be passed along dynamically, or can be configured into the individual routers.
Most dynamic interior routing protocols include a mechanism for causing a smart router to generate dynamic default information that is then passed along to other routers.
Default Network
If a router has an interface that is directly connected to the specified default network, the dynamic routing protocols running on the router will generate or source a default route. In the case of Routing Information Protocol (RIP), the router advertises the pseudonetwork 0.0.0.0. In the case of Interior Gateway Routing Protocol (IGRP), the network itself is advertised and flagged as an exterior route.
A router that is generating the default for a network also may need a default of its own. One way a router can generate its own default is to specify a static route to the network 0.0.0.0 through the appropriate device.
Gateway of Last Resort
When default information is being passed along through a dynamic routing protocol, no further configuration is required. The system periodically scans its routing table to choose the optimal default network as its default route. In the case of RIP, there is only one choice, network 0.0.0.0. In the case of IGRP, there might be several networks that can be candidates for the system default. The Cisco IOS software uses both administrative distance and metric information to determine the default route (gateway of last resort). The selected default route appears in the gateway of last resort display of the show ip route EXEC command.
If dynamic default information is not being passed to the software, candidates for the default route are specified with the ip default-network global configuration command. In this usage, the ip default-network command takes an unconnected network as an argument. If this network appears in the routing table from any source (dynamic or static), it is flagged as a candidate default route and is a possible choice as the default route.
If the router has no interface on the default network, but does have a route to it, it considers this network as a candidate default path. The route candidates are examined and the best one is chosen, based on administrative distance and metric. The gateway to the best default path becomes the gateway of last resort.

Monitoring Environmental Parameters
The Cisco Connected Grid Router 2010 includes sensors that measure the status and internal temperature of critical components. Internal component temperatures are measured for the central processor, internal components, and interface cards. A 72-hour temperature history is stored for the central processor at one-hour intervals.
Power consumption and power supplies are monitored. The measured temperature is compared to predetermined threshold limits and, if the temperature does not fall within the limits, the information is recorded and a warning sent to the system administrator by means of Simple Network Management Protocol (SNMP) traps until the temperature falls back to its normal range.
A command-line interface (CLI) command allows the display of the current system environment and temperature status.
Use the following CLI to monitor the system environment:
Router# show environment {all | last | table}
where:
- all—Displays all environmental monitor parameters
- last—Displays the last environmental monitor parameters
- table—Displays the table of temperature and voltage ranges
The following example shows a sample output of the show environment all command. In the following example, the power supplies are external:
Router# show environment all
