IP Configuration window 188
Models 2616RC, 3096RC & 3196RC Admin Reference Guide 12 • IP (IP, TCP, UDP, & ICMP)
# Valid but Discarded
The number of routing entries which were chosen to be discarded even though they are valid. One possible
reason for discarding such an entry could be to make more buffer space available for other routing entries.
IP Configuration window
The IP Configuration window (see figure 104) provides the means for you to view and modify the values of the
IP Forwarding and Default Time-to-Live parameters for the T-DAC.
Figure 104. IP Configuration window
To display the IP Configuration window, on the IP Overview window (see figure 102 on page 183), click the
Modify… link.
IP Configuration
The following sections describe the IP parameters displayed on the IP Configuration window.
Forwarding (ipForwarding)
Determines whether the T-DAC is acting as an IP gateway that will forward datagrams received by-but not
addressed to-the T-DAC. IP gateways forward datagrams, IP hosts do not (except those source-routed via
the host).
Note
For some managed nodes, this object may take on only a subset of the
values possible. Accordingly, it is appropriate for an agent to return a
“badValue” response if a management station attempts to change this
object to an inappropriate value.
The following options are available:
• forwarding(1)—acting as a gateway
• not-forwarding(2)—not acting as a gateway
Default Time-To-Live (ipDefaultTTL)
The default value inserted into the Time-To-Live (TTL) field in the IP header of datagrams originating from
the T-DAC, whenever a TTL value is not already supplied by the transport layer protocol.
Saving your work
Once you have defined your desired values for the configurable parameters shown in the IP Configuration win-
dow, you must click the Modify button to save the new values into volatile DRAM. Once you click the but-
ton, the T-DAC will implement the changes immediately.
