Configuring the DLCI to IP Mapping
When connected to a Frame Relay network, Business Communications Manager uses Frame
Relay INARP (Inverse Address Resolution Protocol) messaging to request the next hop protocol
address for a given DLCI. If the other end of the connection does not support INARP messaging,
there can be a communication failure because the mapping of which DLCI to use to reach a
particular IP address is not known.
The DLCI to IP Mapping feature solves this problem by providing static address mapping of the
DLCI to remote IP address.
Adding DLCI to IP Mapping
You can add up to 32 DLCI to IP Mapping entries.
To add a DLCI to IP Mapping entry:
1 On the navigation tree, click the Resources key and click the WAN key.
2
Click the WAN1 or WAN2 heading.
The WAN Summary screen appears.
3
Click the DLCI to IP Mapping tab.
The DLCI to IP Mapping screen appears.
4
On the Configuration menu, click Add DLCI to IP Mapping .
The DLCI to IP Mapping dialog box appears.
5
Configure the DLCI to IP Mapping parameters using the information in the following table.
6
Click the Save button.
Note: DLCI to IP Mapping feature is available only on the WAN1 and WAN2 interfaces.
This feature is not available on the UTWAN interface.
Table 183 DLCI to IP Mapping parameters
Attribute Description
Index (I#) This parameter identifies the DLCI to IP Mapping entry.
This is a read only parameter.
Local IP Enter the IP address used for the local end of this connection. The IP address you enter must
be one of the IP address assigned to this WAN interface.
You must enter the IP address in standard decimal format (for example 10.10.10.1).
DLCI Enter the Data Link Connection Identifier (DLCI) number for this interface.
You can enter a value from 0 to 1024.
Remote IP Enter the IP address used for remote end of this connection.
You must enter the IP address in standard decimal format (for example 10.10.10.1).
