Troubleshooting
Basic Troubleshooting Tools
From the TMS zl Module’s CLI, enter the following command from either the
manager-level context or the global configuration context:
Syntax: ping < IP address | hostname >
Replace <IP address> with the IP address of the ping destination.
Replace <hostname> with the host name of the ping destination.
The module displays the number of pings sent and the number of responses
received.
For example, to ping a device with the IP address of 192.168.1.101, enter:
hostswitch(tms-module-C)# ping 192.168.1.101
If you need to stop a ping operation, press
Ctrl+Z.
traceroute
The traceroute command not only verifies that a packet can reach its destina-
tion but also reports the number of hops between two endpoints.
To use traceroute on a TMS zl Module that is operating in routing mode, you
must perform an additional step. You must create an access policy that permits
ICMP echo packets (pings) from one endpoint—the source—to another—the
destination. (For more information about creating this access policy, see
“Firewall Access Policies” in Chapter 4: “Firewall.”)
Enter the following command from either the manager-level or global config-
uration context in the TMS zl Module’s CLI.
Syntax: traceroute <IP address> [extended options]
Replace <IP address> with the IP address of the final destination to which
you want to trace the route.
The module will display a route to a destination up to 255 hops away. You can
end the traceroute process at any time by pressing
Ctrl+Z. The following is
example of the traceroute output:
hostswitch(tms-module-C)# traceroute 10.1.1.2
traceroute to 10.1.1.2 (10.1.1.2), 30 hops max, 40 byte
