Testing with Network Diagnostic and Shell Tools
The T1000 CLI includes a set of network diagnostic tools that enable testing and
troubleshooting of data plane and management plane configurations. Refer to the following
topics.
• “Checking Connectivity with the ping Command” on page 3-29
• “Tracing Packets with the trace-route Command” on page 3-29
• “Capturing and Filtering Packets with the nstrace Command” on page 3-30
• “Accessing the UNIX Shell” on page 3-30
Checking Connectivity with the ping Command
Use the ping command to initiate Internet Control Message Protocol (ICMP) echo requests
from the T1000 to a specific host. When ping is run, returned messages from the host
indicate a valid network connection between the T1000 and the host. If no messages are
returned, it may indicate a configuration error on the T1000 interface, a faulty connection
between network elements, or a host that is not responding for various reasons (out of
service, misconfigured, or not responsive to ping requests).
Use the ping command as follows:
ping [-c count] [-i interval] [-I interface] [-n] [-p pattern] [-q] [-s siz] [-S src_addr] [-t
timeout] hostname
See the ping command in Appendix A, “T1100 CLI Reference” for information on the
parameters.
For example:
ping -p ff -c 4 10.102.4.107
Note: For networks supporting IPv6, the T1000 also supports the ping6 command.
See ping6.
Tracing Packets with the trace-route Command
Use the trace-route command to trace the path a packet takes between the active T1000 and
a specified host, such as a next-hop gateway or a server on the operator’s network.
Use the traceroute command as follows:
traceroute [-S] [-n] [-r] [-v] [-M min_ttl] [-m max_ttl] [-P protocol][-p portno] [-q
nqueries] [-s src_addr] [-t tos] [-w wait] host [packetlen]
See the traceroute command in Appendix A, “T1100 CLI Reference” for information on the
parameters.
For example:
traceroute 10.102.4.107
