       type interface-wildcard
       type atm-vci

Mode: Configuration Mode

Description:

The value accepted by all DDL interface types always includes a portion that represents the physical device itself. The acceptable value for this portion depends on the kind of interface.

• GRE interfaces, the acceptable value is gre
• IP-IP interfaces, the acceptable value is ipip
• For the first management interface, the acceptable value is fxp0. The second management interface is fxp1.
• For other kinds of interfaces, the values have the following syntax:

          type-fpc/pic/port[:channel]

type specifies the media type, such as at for atm interfaces or ge for Gigabit Ethernet interfaces.

fpc is the number for the flexible PIC concentrator (FPC) that houses the physical interface.

pic is the number of the Physical Interface Card (PIC) that houses the physical interface.

port is the number of the port on the PIC that corresponds to the physical interface.

channel is the channel number assigned to the interface. It is required for channelized interfaces, but optional for all other kinds.

DDL has the following interface types defined:

• interface-device type-fpc/pic/port[:channel]

           name of the physical interface device plus an optional channel identifier (e.g. fe-0/0/0)

• interface-unit type-fpc/pic/port[:channel][.logical-unit]

          name of either a physical interface device or logical interface device. (eg. fe-0/0/0 or fe-0/0/0.0)

• interface-name type-fpc/pic/port[:channel].[logical-unit]

          name of a logical interface device. It is the interface-device type plus an optional unit number. If the user does not provide the logical-unit-number, the CLI assigns the default value of 0 (zero). (e.g. fe-0/0/0.1)

• interface-wildcard type-fpc/pic/port[:channel].[logical-unit]

          a logical-interface device name that has wildcards in one or more fields. Each field in the name accepts a numerical value can contain instead contain the * (asterisk) wildcard. (e.g. fe-0/*/1.*)

• atm-vci vpi.vci

          to require that the user provide a virtual circuit identifier (VCI) for an Asynchronous Transfer Mode (ATM) interface. The vpi portion defines the Virtual Path Identifier (VPI) for the ATM interface and can range from 0 to 255. The vci defines the VCI and can range from 0 to the maximum value value defined for VPIs in the configuration: the absolute possible maxima differ for regular and multicast circuits. A VPI/VCI pairing of 0.0 is not a legal pairing.

Example:

        object newbie {
            help "Newbie DDL testing";
            flag setof list ;

            object interface {
                help "Interface-unit example (has to be atm)";
                flag identifier nokeyword;
                type interface-unit;
                match "at";
            }

            attribute atm-vci {
                 help "Test atm-vci type";
                 type atm-vci;
            }
        }
