IGX Configuration Summary
Figure 3-22 illustrates the sequence of using addshelf either locally or remotely to add one or more
interface shelves. To delete an interface shelf, use delshelf after you delete connections and the
active interfaces. To view status of an interface shelf, execute dspnode at the routing hub. (The
dspnw command shows an alarm on a node but does not specify an interface shelf.)

Adding Connections in a Tiered Network through the CLI
Adding a connection in a tiered network requires that you add local segments and a network
segment. The following steps illustrate the setup for each segment for an interworking connection:
Step 1
Step 2
Step 3
Note that the vpi and vci need to match only at the segment on the local interface shelf. Apart from
this requirement, the vpi.vci on segment 1 can also be the same as the vci.vpi on segment 2.
Converting a Routing Node to an Interface Shelf
To convert a routing node to an interface shelf, first remove the routing node from the network by
deleting all connections then deleting and downing all lines and trunks. Refer to Cisco WAN
Manager documentation or the Cisco WAN Switching Command Reference for instructions. In the
command reference, check the chapters by topic (ATM connections, Frame Relay connections,
trunks, and so on) for the applicable command descriptions. Next, you need to add the node as an
interface shelf. Refer to the section "Configuring an IGX Switch to Be an Interface Shelf" page 51
for instructions.

For segment 1:
addcon slot.port.DLCI local_nodename slot.vpi1.vci1
where the first slot has a Frame Relay card, and the second slot has a BTM. (In an IGX
interface shelf, the only card that supports the trunk to the hub is the BTM.)
The network segment:
addcon slot.port.vpi1.vci1 remote_nodename slot.port.vpi2.vci2
where the card in slot is a BNI
For segment 2:
addcon slot.vpi2.vci2 local_nodename slot.port.DLCI
where the second slot is a Frame Relay card.
