To set a restriction for an IPSec tunnel, use the ike ipsec policies set interface
command. The interface that you specify on the command is the remote interface that
the tunnel is to be restricted to. To restrict the tunnel to the backup interface, specify
the remote name that you created for the dialup parameters as described in
“Specifying the Dialup Parameters” on page 6-9.
Configuring Dial Backup
To set up the router to use the Dial Backup feature, you must:
• If your router has an internal modem and you choose to use it, a feature key
must be installed (see “Key Enabled Features” on page 4-29); if not, an
external modem must be used.
• Connect an asynchronous modem to the console port of the router if
required.
• Special DB9 or DB25 connectors may be required. Special modem kit and/or
connector packages are available from Efficient Networks.
• Configure the router software to use the Dial Backup feature.
To begin Dial Backup configuration, you can select options using the Web
Management Interface (“Dial Backup” on page 8-68) or review the sample
configuration discussed in this chapter. Further configuration may require the CLI
commands described in this section.
NOTE:
Because Dial Backup uses the console port, you cannot enter CLI commands using
the console port while Dial Backup is enabled. While Dial Backup is enabled, you
must access the command line via Telnet.
The following is a general outline of the steps required to configure Dial Backup.
These steps are detailed in the sections that follow. To configure Dial-Backup:
Step 1 Check that the Internal Modem feature is installed in the router. To do so, enter the
key list command and look for the presence of a Intmodem key in the list. For more
information, see “Listing the Installed Feature Keys” on page 4-32. If no key is
present, an external modem must be connected.
Step 2 Define a remote profile for Dial Backup that specifies the ISP phone number and
other dialup parameters.
Step 3 Specify the conditions that determine the status of the DSL link. Default values are
provided for:
• Minimum stability period for the DSL link status signal
• Minimum retry period before DSL link restoration is attempted
