tion
encapsulation-type
Encapsulation type, with nonstandard, ietf, multi-protocol and snap
available.
idle-timer minutes
Maximum idle time for the virtual circuit associated with the address
mapping. 0 means that the idle time is infinite.
no-callin Disables accepting calls to the address mapping.
no-callout Disables calls originating from the address mapping.
packet-size input-size output-size
Carries out maximum packet size negotiation when initiating calls from
the mapping. It needs the following parameters: maximum input packet
size and maximum output packet size, which are both in the range of 16
to 4096 bytes 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 calls from the address mapping to carry reverse charging
requests.
roa-list roa-name
Specifies an ROA list name for the X.25 interface. The roa name is a
string of 1 to 19 characters.
send-delay delay-time
Carries out the maximum network transmission delay negotiation when
initiating calls from the mapping. The delay time is in the range 0 to
65534 ms.
threshold input-value output-value
Specifies threshold values when initiating throughput negotiation with the
peer from the mapping. The values of input/output can only be 75, 150,
300, 600, 1200, 2400, 4800, 9600, 19200, or 48000.
vc-per-map count
Maximum number of VCs associated with the address mapping, in the
range 1 to 8.
window-size input-window-size
output-window-size
Carries out the window size negotiation with the peer when initiating
calls from the address mapping, including input window size and output
window size. When the modulo is 8, the size is in the range 1 to 7. When
the modulo is 128, it is in the range 1 to 127.
Usage guidelines
Since X.25 protocol can multiplex multiple logical virtual circuits on a physical interface, you need to
manually specify the mapping relation between all network addresses and X.121 addresses.
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
by using 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.
Examples
# Set two address mappings on the X.25 interfaces Serial2/1 and Serial 2/0, respectively, and the four
address mappings have different attributes.
<Sysname> system-view
[Sysname] interface serial 2/1
