4 — IP Routes
When the P117F(R) is in
Whenever the agent sends a packet to a management station that does not reside on the same network, the agent searches an internal table to determine via which router the packet should travel. Part of this internal table is built from the data you enter for the IP Routes parameter. The IP Routes parameter correlates host or network destination addresses (of management stations) with gateway addresses.
You may define multiple IP Routes from the agent to the management station. As the agent searches the IP Routes table, it will select the gateway that was added last. If that gateway is unavailable, it will proceed to the gateway added before the last one, and so on.
You may also define a default gateway for all management stations rather than define a specific gateway for each possible destination. If the agent cannot find a particular network or host destination address in its IP Routes table, it will use the default gateway (the default gateway is correlated with destination address 000.000.000.000). If the agent cannot find a particular network or host destination address and no default gateway has been defined, the packet will not be sent.
If an agent or P110 stack does not appear on a management station as expected, it may be as a result of the agent not including this station in its IP Route table. Ping the agent to see if the agent is active. The agent and stack may be operating normally even though the management station is not communicating with the agent.
To define an IP route, you must supply:
•The IP address of the station or the network (not subnet)
•The IP address of the gateway (router).
