▼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
