▼ To Check the IP Routing
1. Check the IP routing table using the netstat(1M) command:
2. Check that the FDDI subnetwork is featured in the routing table.
If the routing table is empty, check that the routing daemon ( in.routed ) is
running on your machine.
▼ To Check the Protocol Statistics
♦ Use netstat(1M) to check the per-protocol (IP, TCP, UDP, etc.) statistics
for errors:
% netstat —nr
# netstat -s
