Line Card Interfaces

Because of the wide variety of line cards supported by Cisco 12006 and

Cisco 12406 Routers, you should see the configuration note that shipped with a particular card for interface configuration information. This section provides several examples to show the general way the setup command utility handles line card interface configuration.

The following sample excerpt from a System Configuration Dialog session for a Quad OC-3cPOS line card shows settings for a typical configuration:

Configuring interface POS3/0:

Is this interface in use?: yes

Configure IP on this interface?: yes

Configure IP unnumbered on this interface?: no

IP address for this interface: 2.1.1.1

Number of bits in subnet field: 0

Class A network is 2.0.0.0, 0 subnet bits; mask is 255.9.0

Configure CLNS on this interface?: yes

Note By default, POS interfaces use the 32-bit cyclic redundancy check (CRC) and high-level data link control (HDLC) as the encapsulation protocol.

The following sample shows the same Quad OC-3c POS line card interface being configured for IP unnumbered:

Configuring interface POS3/0:

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

In the following sample, an ATM line card is being configured to use IP:

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 255.9.8.0
