x.121-address: X.121 address of the peer host.
option: Specifies some attributes or user facilities for the address mapping.
Description
Using the x25 map command, you can set the address mapping between IP
address used by LANs and X.121 address. Using the undo x25 map command, you
can delete one existing mapping.
By default, no address mapping is set.
Since X.25 protocol can multiplex more logical virtual circuits on a physical
interface, you need to manually specify the mapping relation between all network
addresses and X.121 address.
Once you have specified an address mapping, its contents (including protocol
address, X.121 address and all options) cannot be changed. To make
modifications, you can first delete this address mapping via the undo x25 map
command, and then establish one new address mapping.
Two or more address mappings with an identical protocol address shall not exist
on the same X.25 interface.
Detailed explanations are as follows:
broadcast: Sends any broadcasts of internetworking protocol and the multicast
of IP to the destination. This option provides powerful support for some routing
protocols (such as Routing Information Protocol).
closed-user-group group-number: Number of the closed user group
corresponding to this address mapping.
encapsulation-type: Encapsulation type, optional types include nonstandard,
ietf, multi-protocol and snap.
idle-timer minutes: Maximum idle time for the VC associated with the address
mapping. 0 means that the idle time is infinite.
no-callin: Disables accepting call to the address mapping.
no-callout: Disables call originating from the address mapping.
packet-size input-packet output-packet: When the address mapping is used to
originate a call, it will negotiate the maximum packet size in bytes with the
peer end. Its value must range from 16 to 4096 (including 16 and 4096), and
must be the integer power of 2.
reverse-charge-accept: If a call initiated by the address mapping carries reverse
charging request, to accept the call, this option must be configured in the
address mapping.
reverse-charge-request: Specifies reverse charging request while calling from
the address mapping.
roa-list name: Specifies an ROA list name configured by the command X25
roa-list in system view for the X.25 interface.
send-delay milliseconds: When the address mapping is used to originate a call,
it carries the maximum transmission delay request.
