By default routers are configured to resolve every word that is not a command. It will first look in static DNS table for an entry. If you are not going to use DNS server or hostname facility, it is better to turn this off.

It will save your time because every incorrectly typed command will cost you a wait of minute or two. Whenever IOS has any kind of notification, it will display that on command prompt.

It fines until prompt is free. What if you are typing a command and notification line appears in the middle of the command? This is really annoying. Luckily we can stop this behavior. After this if IOS has anything to display it will move prompt and your typed command in next line. Notification will not insert in the middle of command.

If you continue typing, the command will execute properly, even though it looks wrong at prompt. Cisco IOS has a great security feature to secure the console line.

It automatically logs out ideal connection in 10 minutes. You can disable this feature in lab environment. Serial interface is used to connect wan network. Serial cable is used to connect serial interfaces. You only need to provide clock rate and bandwidth in DCE side.

Usually FastEthernet connects local network with router. For security reason, we should always disable unused interface on router. Router keeps configuration in RAM. All settings that we have made in this article will erase once the router reboot.

To preserve this configuration after reboot we must have to save this. We have done our practice now make it available for next round of practice. We do not accept any kind of Guest Post.

Basic Routing Concepts and Protocols Explained. Use interface type sub interface number command from global configuration mode or interface configure mode. Use exit to return previous mode. Enter reload command from privileged exec mode.

Starts the ping tool that is used for testing connectivity. If you do not enter a hostname or an IP address on the same line as the ping command, the system prompts you to specify the target IP address and several other command parameters. After specifying the target IP address, you can specify alternate values for the remaining parameters or accept the displayed default for each parameter. The bulk option enables you to check reachability to multiple destinations.

You must hit the Enter button and then specify one destination address per line. The traceroute command allows you to trace the routes that packets actually take when traveling to their destinations.

Traces packet routes through the network. If you do not enter a hostname or an IP address on the same line as the traceroute command, the system prompts you to specify the target IP address and several other command parameters.

DNS-based hostname-to-address translation is enabled by default. If hostname-to-address translation has been disabled using the domain lookup disable command, re-enable the translation using the no domain lookup disable command.

Specifies the address of a name server to use for name and address resolution hosts that supply name information. For security reasons, the TFTP server requires that a file must already exist for a write request to succeed. The server and client router must be able to reach each other before the TFTP function can be implemented.

Verify this connection by testing the connection between the server and client router in either direction using the ping command. IPv4 or IPv6 address prefixes required. Maximum number of concurrent TFTP servers required. Name of the associated access list optional. Displays the network service for each process. For the rcp copy request to execute successfully, an account must be defined on the network server for the remote username.

For UNIX systems, you must add an entry to the hosts file for the remote user on the rcp server. Specifies the name of the remote user on the rcp server. This name is used when a remote copy using rcp is requested. If the rcp server has a directory structure, all files and images to be copied are searched for or written relative to the directory in the remote user account.

When using rcp to copy any file from a source to a destination, use the following path format:. This task allows you to configure the router to use FTP connections for transferring files between systems on the network. Allows the software to use only passive FTP connections.

Specifies the password for anonymous users. When using FTP to copy any file from a source to a destination, use the following path format:. If unsafe or reserved characters appear in the username, password, hostname, and so on, they have to be encoded RFC The directory-path is a relative path to the home directory of the user.

For example:. This task allows you to configure a router to use TFTP connections. When using TFTP to copy any file from a source to a destination, use the following path format:. This task allows you to configure Telnet services.

Enables one inbound Telnet server on the router. This command affects only inbound Telnet connections to the router. You can transfer one file at a time. If the destination is a server, SSH server process must be running. Perform this task to configure the logging source interface to identify the syslog traffic, originating in a VRF from a particular router, as coming from a single device.

Configures the logging source interface to identify the syslog traffic, originating in a VRF from a particular router, as coming from a single device.

ICMP Echo is useful for troubleshooting network connectivity issues. The following example shows an extended ping command sourced from the Router A Ethernet 0 interface and destined for the Router B Ethernet interface.

If this ping succeeds, it is an indication that there is no routing problem. Also, both hosts have their default gateways set correctly. If the extended ping command from Router A fails, it means that there is a routing problem. You should correct any routing problems, and then Host 1 should try to ping Host 2. If Host 1 still cannot ping Host 2, then both hosts' default gateways should be checked. The connectivity between the Ethernet of Router A and the Ethernet of Router B is checked with the extended ping command.

With a normal ping from Router A to Router B's Ethernet interface, the source address of the ping packet would be the address of the outgoing interface; that is, the address of the serial 0 interface When Router B replies to the ping packet, it replies to the source address that is, This way, only the connectivity between the serial 0 interface of Router A To test the connectivity between Router A's Ethernet 0 With extended ping , we get the option to specify the source address of the ping packet.

In this example, the extended ping command verifies the IP connectivity between the two IP addresses The traceroute command is used to discover the paths packets take to a remote destination and where routing breaks down.

The traceroute command provides the path between the two IP addresses and does not indicate any problems along the path. The following sections provide references related to implementing host services and addresses on the Cisco ASR Series Router. No new or modified standards are supported by this feature, and support for existing standards has not been modified by this feature.

Updated: December 15, Chapter: Implementing Host Services and Applications.

Implementing Host Services and Applications Cisco IOS XR software Host Services and Applications features on the router are used primarily for checking network connectivity and the route a packet follows to reach a destination, mapping a hostname to an IP address or an IP address to a hostname, and transferring files between routers and UNIX workstations. Ping Traceroute Ping The ping command is a common method for troubleshooting the accessibility of devices.

Traceroute Where the ping command can be used to verify connectivity between devices, the traceroute command can be used to discover the paths packets take to a remote destination and where routing breaks down.

TFTP Server It is too costly and inefficient to have a machine that acts only as a server on every network segment. Cisco inetd Cisco Internet services process daemon Cinetd is a multithreaded server process that is started by the system manager after the system has booted.

Telnet Enabling Telnet allows inbound Telnet connections into a networking device. Note If you do not enter a hostname or an IP address on the same line as the ping command, the system prompts you to specify the target IP address and several other command parameters.

Checking Network Connectivity for Multiple Destinations The bulk option enables you to check reachability to multiple destinations. Step 2 [ vrf vrf-name ] [ host-name ip-address ] Example: Please enter input via CLI with one destination per line: vrf myvrf1 1. Type escape sequence to abort. Checking Packet Routes The traceroute command allows you to trace the routes that packets actually take when traveling to their destinations.

Note If you do not enter a hostname or an IP address on the same line as the traceroute command, the system prompts you to specify the target IP address and several other command parameters. Configuring Domain Services This task allows you to configure domain services. Before you begin DNS-based hostname-to-address translation is enabled by default.

Note You can enter up to six addresses, but only one for each command. Note You can bind up to eight additional associated addresses to a hostname. Note For security reasons, the TFTP server requires that a file must already exist for a write request to succeed. Before you begin The server and client router must be able to reach each other before the TFTP function can be implemented. Configuring a Router to Use rcp Connections This task allows you to configure a router to use rcp.

Before you begin For the rcp copy request to execute successfully, an account must be defined on the network server for the remote username. Configuring Telnet Services This task allows you to configure Telnet services. Note This command affects only inbound Telnet connections to the router. Configuring syslog source-interface Perform this task to configure the logging source interface to identify the syslog traffic, originating in a VRF from a particular router, as coming from a single device.

The default is milliseconds.
