Using the ping Command to Verify Network Connectivity

The ping command is a convenient way to test the ability of an interface to send and receive packets over the
network.
The ping command sends ICMP echo request packets to a specified destination address, which should send
an equal number of ICMP echo reply packets in reply. By measuring the numbering of packets that are
successfully returned, as well as how long each packet takes to be returned, you can quickly obtain a rough
idea of the Layer 3 to Layer 3 connectivity between two interfaces.
The IP ping command has the following syntax: ping
or ping ip-address [repeat count ] [data hex ] [size datagram-size ]
If you enter just ping, the command interactively prompts you for all other parameters. Otherwise, you must
specify at least a specific IP address as the destination for the ping. You can also optionally specify the
following parameters:
• repeat count —Number of ICMP echo request packets to send. The default is five packets.
• data hex —The data pattern, in hexadecimal, to be sent in the ICMP echo request packets.
• size datagram-size —Specifies the size, in bytes, of the ICMP echo request packets to be sent. The range
Displaying Additional ATM SPA Data
The following sections describe additional ATM SPA data that can be displayed:
Displaying ATM SPA Hardware Information
Use the following commands to display different types of hardware and system information:
• show version
Displays information about the router, its system hardware and software, and the number of each type of
interface that is installed.
• show hw-module subslot fpd
Displays information about the hardware revision of the SPA, as well as the version of the field-programmable
device (FPD) that is onboard the SPA. Cisco technical engineers might need this information to debug or
troubleshoot problems with a SPA installation.
• show idprom module
Displays the serial number and board revisions for the ATM SPA.
• show controllers atm
