map-list

To specify a map group and link it to a local E.164 or X.121 source address and a remote E.164 or X.121 destination address for Frame Relay switched virtual circuits (SVCs), use the map-list global configuration command. To delete a previous map-group link, use the no form of this command.

map-list map-group-name source-addr {e164 | x121} source-address dest-addr {e164 | x121} destination-address

no map-list map-group-name source-addr {e164 | x121} source-address dest-addr {e164 | x121} destination-address

Syntax Description

map-group-name

Name of the map group. This map group must be associated with a physical interface.

source-addr {e164 | x121}

Type of source address.

source-address

Address of the type specified (E.164 or X.121).

dest-addr {e164 | x121}

Type of destination address.

destination-address

Address of the type specified (E.164 or X.121).

Defaults

Disabled

Usage Guidelines

Use the map-class command and its subcommands to define quality of service (QoS) parameters---such as incoming and outgoing CIR, committed burst rate, excess burst rate, and the idle timer---for the static maps defined under a map list.

Each SVC needs to use a source and destination number, in much the same way that a public telephone network needs to use source and destination numbers. These numbers allow the network to route calls from a specific source to a specific destination. This specification is done through map lists.

Based on switch configuration, addressing can take either of two forms: E.164 or X.121.

An X.121 address number is 14 digits long and has the following form:

Z CC P NNNNNNNNNN

The table below describes the codes in an X.121 address number form.

 
Table 22:   X.121 Address Numbers
Code Meaning Value

Z

Zone code

3 for North America

C

Country code

10-16 for the United States

P

Public data network (PDN) code

Provided by the PDN

N

10-digit number

Set by the network for the specific destination

An E.164 number has a variable length; the maximum length is 15 digits. An E.164 number has the fields shown in Figure 2.

Field Description

Country Code

Can be 1, 2, or 3 digits long. Some current values are the following:

  • Code 1---United States of America

  • Code 44---United Kingdom

  • Code 61---Australia

National Destination Code + Subscriber Number

Referred to as the National ISDN number; the maximum length is 12, 13, or 14 digits based on the country code.

ISDN Subaddress

Identifies one of many devices at the termination point. An ISDN subaddress is similar to an extension on a PBX.

Examples

In the following SVC example, if IP or AppleTalk triggers the call, the SVC is set up with the QOS parameters defined within the class hawaii. An SVC triggered by either protocol results in two SVC maps, one for IP and one for AppleTalk. Two maps are set up because these protocol-and-address combinations are heading for the same destination, as defined by the dest-addr keyword and the values following it in the map-list command. 

map-list bermuda source-addr E164 123456 dest-addr E164 654321
ip 131.108.177.100 class hawaii
appletalk 1000.2 class hawaii
