Hyperlinks
The IP Overview window provides the following hyperlinks to the windows shown in figure 103. You can use
these pages to view and modify the values of certain IP parameters:
• TCP—Clicking the TCP hyperlink displays the TCP Overview window (see section “TCP Overview win-
dow” on page 198).
• UDP—Clicking the UDP hyperlink displays the UDP Overview window (see section “UDP Overview win-
dow” on page 201).
• ICMP—Clicking the ICMP hyperlink displays the ICMP Overview window
(see section “ICMP Overview
window” on page 203).
• Modify—Clicking the Modify hyperlink displays the IP Configuration window where you can modify the
values of the IP forwarding and time-to-live parameters (see “IP Configuration window” on page 188).
• Addressing Info—Clicking the Addressing Info hyperlink displays the IP Addressing Overview window. This
window (see “IP Addressing Overview window” on page 189) displays each IP address and its associated T-
DAC interface ID number, and a Details…. for each IP address. The Details hyperlink displays the IP
address Details window for that IP address.
• Routing Info—Clicking the Routing Info hyperlink displays IP Routing Overview window. This window
displays the defined IP routes table that the T-DAC uses to routing IP datagrams. For each route, the table
shows the IP address, subnet mask, next hop router, and interface) You can use this window to add IP
routes to the T-DAC’s routing table by defining IP routing parameters (see “IP Routing Overview window”
on page 190).
• Address Translation Info—Clicking the Address Translation Info hyperlink displays the IP address transla-
tion window where you can view and define the T-DACs physical to logical (MAC to IP) address correla-

IP Parameters
The following sections describe the IP parameters displayed on the IP Overview window.
Forwarding
The Forwarding parameter defines whether the T-DAC acts as an IP gateway in respect to the forwarding of
datagrams received by, but not addressed to the T-DAC. IP gateways forward datagrams. IP hosts do not for-
ward datagrams, except in the case when the host is the source of the datagram.
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.
One of the following values may be defined for ipForwarding:
• forwarding(1)—acting as a gateway and will forward IP datagrams to other gateways
• not-forwarding(2)—not acting as a gateway so it will discard IP datagrams destined for other gateways
