Monitoring TCP/IP information can give you a clear view of the status of your TCP/IP network and whether the router is configured properly to run efficiently in the network. This information can also be helpful in troubleshooting and optimizing of the network.
To check the TCP/IP routing table and information associated with each route, load TCPCON and then select IP Routing Table > Proceed > entry you want to view.
The IP Routing Table window shows you all known TCP/IP destination networks and the following information about each item:
IP address of the destination
IP address of the next hop router
Type of the route (direct, remote)
Primary cost for the route
Interface used to reach a route
The IP Route Information window expands on this by showing information about the mask used, the routing protocol through which the destination was learned, and the age of the route.
You can view, and sometimes change, the configuration of TCP/IP protocols configured for use in your router. You can reach this information by loading TCPCON and selecting Protocol Information. You can configure and view statistics and other information for the following protocols:
EGP
ICMP
IP
OSPF
TCP
UDP
