Using the ping Command to Verify Network Connectivity

The ping command allows you to verify whether a modular port adapter (MPA) port is functioning properly and to check the path between a specific port and connected devices at various locations on the network.

After you verify that the system and the modular line card (MLC) have booted successfully and are operational, you can use the ping command to verify the status of the MPA ports. See the Cisco ASR 9000 Series Aggregation Services Router Getting Started Guide and the Cisco ASR 9000 Series Aggregation Services Router Interface and Hardware Component Configuration Guide for more information on bringing up and configuring the Cisco ASR 9000 Series Router and the Cisco ASR 9000 A9K-MOD80G-H.

The ping command sends an echo request out to a remote device at an IP address that you specify. After sending a series of signals, the command waits a specified time for the remote device to echo the signals. Each returned signal is displayed as an exclamation point (!) on the console terminal; each signal that is not returned before the specified timeout is displayed as a period (.). A series of exclamation points (!!!!!) indicates a good connection; a series of periods (.....) or the messages [timed out] or [failed]

indicate that the connection failed.

This is an example of a successful ping command to a remote server with the IP address 10.1.1.60:

Router# ping 10.1.1.60

Type escape sequence to abort.

Sending 5, 100-byte ICMP Echoes to 10.1.1.60, timeout is 2 seconds:

!!!!!

Success rate is 100 percent (5/5), round-trip min/avg/max = 1/15/64 ms Router#

If the connection fails, verify that you have the correct IP address for the destination device and that the destination device is active (powered on), and then repeat the ping command.
