5.5.10 Set X.25 transport
X.25 support is most commonly configured as a transport for datagrams across an X.25 network.
Datagram transport (or encapsulation) is a cooperative effort between two hosts communicating across
an X.25 network. You configure datagram transport by establishing a mapping on the encapsulating
interface between the far host's protocol address (for example, IP address) and its X.121 address.
Perform the tasks in the following sections, as necessary, to complete the X.25 configuration for your
network needs:
♦ Mapping Protocol Address to X.121 Address
1. Mapping protocol addresses to X.121 addresses
This section describes the X.25 single-protocol and multiprotocol encapsulation options that are
available and describes how to map protocol addresses to an X.121 address for a remote host. This
section also includes reference information about how protocols are identified.
Encapsulation is a cooperative process between the router and another X.25 host. Because X.25 hosts
are reached with an X.121 address, the router must have a means to map a host's protocols and
addresses to its X.121 address.
Each encapsulating X.25 interface must be configured with the relevant datagram parameters. For
example, an interface that encapsulates IP will typically have an IP address.
You must also establish the X.121 address of an encapsulating X.25 interface using the x25 address
interface configuration command. This X.121 address is the address that encapsulation calls are
directed to. This is also the source X.121 address used for originating an encapsulation call and is used
by the destination host to map the source host and protocol to the protocol address. An encapsulation
virtual circuit must be a mapped at both the source and destination host interfaces.
For each X.25 interface, you must explicitly map each destination host's protocols and addresses to its
X.121 address.
If needed and the destination host has the capability, one host map can be configured to support
several protocols; alternatively, you can define one map for each supported protocol.
To set up connection, perform the following commands in interface configuration mode:
Supply an alias X.121address for the interface
Set DTE T23 clear request, default value=180sec
Modify SNMP interface parameters
Set parameters for X.25
Q(quit)
Set local X.121 address
Set address alias for this port
Add an alias address for this port
Display alias address for this port
