Verifying Network Connectivity
The system supports several commands that you can use to verify and troubleshoot network connectivity. Note that you
cannot test network connectivity until system interfaces and ports have been configured and bound.
cannot test network connectivity until system interfaces and ports have been configured and bound.
Issue the commands specified in this section on a context-by-context basis. Contexts act like virtual private networks
(VPNs) in that they operate independent of the others. Therefore, ports, interfaces, and routes configured in one context
can not be tested from another without additional configuration.

To switch between contexts you must enter the following command at the root prompt for the Exec mode:
context_name is the name of the context that you wish to switch to. The following prompt appears:
Using the Ping Command
Use the
command to verify the system’s ability to communicate with a remote node in the network by passing
data packets and measuring the response. This command is useful in verifying network routing and whether a remote
node responds at the IP layer. The command has the following syntax:

Keyword/Variable
Description
Identifies the remote node which is the target of the ping command.
specifies the remote node using the node’s assigned IP address
specified with standard IPv4.
Specifies the number of packets to send to the remote host for verification.
must be within the range 1 through 10000. The default is 5.
Specifies a pattern to use to fill the internet control message protocol packets. Specify
in hexadecimal format in the range 0x0000 through 0xFFFF. Begin
with a 0x followed by up to 4 hexadecimal digits.
with a 0x followed by up to 4 hexadecimal digits.
The default is that each octet of the packet is encoded with the octet number of the packet.
Specifies the number of bytes each IP datagram.
must be in the range 40
through 18432. The default is 56.
