Troubleshooting
Problem One
• I have configured the IP address and a gateway. I am pinging the
switch but it is not responding. I am sure the switch is receiving
the ping because it’s port LEDs are flashing and the statistics
menu shows the pings. What is going on?
Is the switch being pinged through a router? If so, the switch gateway address
must be configured. The following figure illustrates the problem.
Workstation
192.168.0.2
Router RuggedSwitch
TM
10.0.0.1 10.0.0.2
192.168.0.1
Figure 6: Using A Router As A Gateway
The router is configured with the appropriate IP subnets and will forward the ping
from the workstation to the switch. When the switch responds, however, it will
not know which its interfaces to use in order to reach the workstation and will
drop the response. Programming a gateway of 10.0.0.1 will cause the switch to
forward un-resolvable frames to the router.
This problem will also occur if the gateway address is not configured and the
switch tries to raise an SNMP trap to a host that is not on the local subnet
