Configuring USP Interfaces
LAll CLI commands mentioned in this section are described in the X330WAN User’s
Guide.
To configure USP interfaces:
1 Use the interface serial <if-number> command to enter the context of the serial
interface you want to configure.
2 If you require Frame Relay encapsulation, continue with step 6.
LAfter the interface is created, its default encapsulation is PPP.
3 Use the ip address <ip address> <mask> command to assign an IP address and a Subnet
mask to the interface.
4Type
exit to return to Supervisor mode.
LIf you need to define more than one IP address on the interface, enter a new interface
serial n.m context, where n is the port number and m is the additional IP interface
index. (For example: typing interface serial 1.1 enables you to configure an IP interface on
interface Serial 1, in addition to the IP interface created in step 3.)
5 Repeat steps 1 through 4 to configure the second USP interface if needed.
6 Use the encapsulation frame-relay command to change the encapsulation type to Frame
Relay.
LThe default value for Frame Relay lmi type is auto-learning, supporting both Annex-A
(Q933) and Annex-D (ANSI).
7Type
exit to return to Supervisor mode.
8 Use the interface serial <if-number>[<if-link-type>] command to enter the Frame
Relay Sub-interface context. (For example, typing interface serial 2.1 point-to-point
creates a Point-to-Point type Sub-interface 1 on port 2.)
LCurrently only Point-to-Point Sub-interface types are supported.
9 Configure a Data Link Connection Identifier (DLCI) for the Sub-interface using the frame-
relay interface-dlci <DLCI number> command.
10 Configure an IP address for the Sub-interface using the ip address <ip address> <mask>
command.
11 Type exit to return to Supervisor mode.
12 Repeat steps 8 through 11 to configure additional Frame Relay Sub-interfaces on the same
Frame Relay interface.
LIf you need to define more than one IP address on the Frame Relay sub-interface, enter a
new interface serial n.m.x context, where nis the port number, mis the sub-
interface index and xis the additional IP interface index.
For example: typing interface serial 1.1.1 enables you to configure an IP interface
on interface Serial 1, sub-interface 1 in addition to the IP interface created in step 10.
