OC-12c/STM-4c Packet-Over-SONET Line Card Installation and Configuration
(Document Number 78-4341-xx) that accompanied your Quad OC-3c/STM-1c
and OC-12c/STM-4c POS line cards, respectively.
Step 3 In the following example, the system is being configured for a POS interface
using IP unnumbered. Respond as appropriate for your needs:
Configuring interface POS4/0:
Is this interface in use?: yes
Configure IP on this interface?: yes
Configure IP unnumbered on this interface?: yes
Assign to which interface: ethernet0
Configure CLNS on this interface?: yes
Repeat Step 2 and Step 3 for each POS interface you need to configure; then, if
you have ATM interfaces installed, proceed to Step 4. Otherwise, proceed to
Step 5 to check and verify your configuration parameters.
Step 4 The Asynchronous Transfer Mode (ATM) interfaces allow connections to
external OC-12/STM-4 networks. In the following example, the system is being
configured for an ATM interface using IP. Respond as appropriate for your
needs, using your own address and subnet mask for the setup prompts:
Configuring interface parameters:
Configuring interface ATM1/0:
Is this interface in use?: yes
Configure IP on this interface?: yes
IP address for this interface: 1.1.1.2
Number of bits in subnet field: 0
Class A network is 1.0.0.0, 0 subnet bits; mask is 255.0.0.0
For the ATM interfaces in your system, additional configuration
Note
parameters might be required before you can fully use these interfaces (such as
configuring permanent virtual circuits [PVCs], and so forth), but are beyond the
scope of this publication.
