9 Troubleshooting information about how to use the tcpdump command, see the Nokia Network Voyager Reference Guide. Under Routing Options in the Routing Configuration section in Network Voyager, you can also enable several types of trace options for DVMRP. These traces are logged into /var/tmp/ipsrd.log. For information about how to access Network Voyager and the related reference materials, see "Accessing Nokia Network Voyager" on page 30. Problem No IP connectivity. Solution Verify that you have IP connectivity; ping various hosts on each network. Problem DVMRP is not enabled on the interfaces. Solution Verify that DVMRP is enabled on the interfaces in use. Problem Exceeding TTL on clients. Solution Verify that the client is set up for the proper TTL number. Many clients are set to receive local traffic only one hop away. Problems Interfacing to 1483 Devices (Classical IP) Problem Remote and local devices are not configured for the same VC and VP value. Solution Set remote and local devices to the same VC and VP values. Consult your 1483 device documentation. Problem Remote and local devices are not in the supported VC range of the network interface card. Solution Use ipsctl to determine the VC range. Enter the following command: ipsctl ifphys:logical interface:max_rxlabel 102 Nokia IP300 Series Security Platform Installation Guide
