Problem
Unable to ping through the unit
Troubleshooting Tips
Localize the problem by issuing pings to various network interfaces on
the IP100 Series NAP. Use tcpdump to trace packets leaving or
entering a port. (See Viewing Packets With tcpdump for further
information.)
Possible Cause
The interfaces are not enabled.
Possible Solution
Ensure that all interfaces are active and up, as described in CHAPTER
3, Configuring the NAP.
Possible Cause
No route exists to the network.
Possible Solution
Check the routing table in Voyager to see if a route exists to the
network where the interface is located. If no route exists, see Routing
Problems, below.
Possible Cause
The routing information for the attached NAP is incorrect.
