Field Reference
Dialer Interfaces on Cisco IOS Routers
Before you can configure a dial backup policy for a site-to-site VPN (see Configuring Dial Backup,
page 24-39), you must configure a dialer interface policy on the appropriate Cisco IOS router. The dialer
interface policy uses dialer pools to associate the dialer interface used by dial backup with a physical
BRI interface on the router. Each dialer interface is associated with a single dialer pool, which can
contain one or more physical interfaces. Multiple dialer interfaces can reference the same dialer pool.
The following topics describe how to create dialer interfaces policies on Cisco IOS routers:
• Defining Dialer Profiles, page 59-27
• Defining BRI Interface Properties, page 59-29
Defining Dialer Profiles
When you configure a dialer profile, you must select the interface or interface role representing the dialer
interface and specify the number to be dialed. You must also assign a pool ID, which you use to reference
this dialer interface when configuring the physical dialer interface. Additionally, you can modify the
default timeout settings for the line.
Note IP is the only protocol supported for dialer profiles by Security Manager.
Note Authentication parameters for the dialer profile are defined in the PPP policy.

Element Description
Interface Name The name of the interface or interface role for which you are
configuring CEF. Enter the name or click Select to select the interface
or interface role. If the object that you want is not listed, click the
Create button to create it.
Enable CEF on Interface Whether to enable CEF on the interface. CEF is enabled by default.
Load Balancing How the interface should balance traffic, either per-destination or
per-packet.
In per-destination load balancing, all packets for a given
source-destination pair take the same path. In per-packet load
balancing, packets for a given source-destination pair can take different
equal-cost routes, and thus reach their destination out of order.
The default is to balance the load based on the destination of the traffic.
