Cisco Systems RSP7000 manual Using the Exec Command Interpreter, Using the Ping Command

Installation Prerequisites

Using the EXEC Command Interpreter

Before you use the configure command, you must enter the privileged level of the EXEC command interpreter with the enable command. The system prompts you for a password if one has been set.

The system prompt for the privileged level ends with a pound sign (#) instead of an angle bracket

(>). At the console terminal, enter the privileged level as follows:

Step 1 At the user-level EXEC prompt (>), enter the enable command. The EXEC command interpreter prompts you for a privileged-level password, as follows:

Router> enable

Password:

Step 2 Enter the password (the password is case sensitive). For security purposes, the password is not displayed.

Step 3 When you enter the correct password, the system displays the privileged-level system prompt (#), as follows:

Router#

The pound sign (#) at the system prompt indicates that you are at the privileged level of the EXEC command interpreter; you can now execute the EXEC-level commands that are described in the following sections.

Using the Ping Command

Before you attempt to upload or retrieve a file from a remote host, ensure that the connection is good between the router and the remote server. The packet internet groper (ping) program sends a series of echo request packets to the remote device and waits for a reply. If the connection is good, the remote device echoes them back to the local device.

The console terminal displays the results of each message sent: an exclamation point (!) indicates that the local device received an echo, and a period (.) indicates that the server timed out while awaiting the reply. If the connection between the two devices is good, the system will display a series of exclamation points (! ! !) or [ok]. If the connection fails, the system will display a series of periods ( . . . ) or [timed out] or [failed].

To verify the connection between the router and a remote host, issue the ping command followed by the name or Internet Protocol (IP) address of the remote server, then press Return. Although the ping command supports configurable options, the defaults, including interface processor as the protocol, are enabled when you enter a host name or address on the same line as the ping command. For a description of the configurable options, refer to the appropriate software documentation.

The following example shows a successful ping:

Router# ping 1.1.1.1

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echos to 1.1.1.1, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 12/12/12 ms Router#
