Configuring a Dialer Interface (Required)

Navigate to the Interfaces level in the configuration hierarchy.

1. In the J-Web interface, select Configuration>View and Edit>Edit Configuration.
2. Next to Interfaces, click Configure or Edit.

From the [edit] hierarchy level, enter

edit interfaces

Create the new interface—for example, dl0.

Adding a description can differentiate between different dialer interfaces—for example, USB-modem-remote-management.

1. Next to Interface, click Add new entry.
2. In the Interface name box, type dl0.
3. In the Description box, type USB-modem-remote-management.
4. Click OK.

Create and name the interface:

1. edit dl0
2. set description USB-modem-remote-management

Configure Point-to-Point Protocol (PPP) encapsulation.

Note: You cannot configure Cisco High-Level Data Link Control (HDLC) or Multilink PPP (MLPPP) encapsulation on dialer interfaces used in USB modem connections.

1. In the Encapsulation column, next to the new interface, click Edit.
2. From the Encapsulation list, select ppp.

Enter

set encapsulation ppp

Create the logical unit 0.

Note: The logical unit number must be 0.

1. Next to Unit, click Add new entry.
2. In the Interface unit number box, type 0.
3. Next to Dialer options, select Yes, and then click Configure.

Enter

set unit 0

Configure the name of the dialer pool to use for USB modem connectivity—for example, usb-modem-dialer-pool.

1. In the Pool box, type usb-modem-dialer-pool.
2. Click OK.

1. Enter

   edit unit 0

2. Enter

   set dialer-options pool usb-modem-dialer-pool

Configure source and destination IP addresses for the dialer interface—for example, 172.20.10.2 and 172.20.10.1.

Note: If you configure multiple dialer interfaces, ensure that the same IP subnet address is not configured on different dialer interfaces. Configuring the same IP subnet address on multiple dialer interfaces can result in inconsistency in the route and packet loss. The router might route packets through another dialer interface with the IP subnet address instead of through the dialer interface to which the USB modem call is mapped.

1. Select Inet under Family, and click Configure.
2. Next to Address, click Add new entry.
3. In the Source box, type 172.20.10.2.
4. In the Destination box, type 172.20.10.1.
5. Click OK.

Enter

set family inet address 172.20.10.2 destination 172.20.10.1
