Confi gure > Protocol Switch > NUA Mappings 4.68
Protocol switch NUA mappings allow you to redirect specified NUAs to alternative NUAs for
switched X.25 calls. Up to twenty “NUA In” to “NUA Out” mappings are available. These mappings
alter the called NUA field in any X.25 call. The comparison uses “tail” matching, so that only the
rightmost digits in the NUA are compared with the table entry.
Using the Web Page(s)
The Configure > Protocol Switch > NUA Mappings web page displays a table with four columns
in which you can specify the NUA In values, corresponding NUA Out values, to which interfaces
the map pings should be applied, and whether the mapping should apply if the unit is making the call,
receiving the call, or both. For example, if the called NUA is 123456789345 and there is an NUA
In table entry of 9345, with Called/Calling set to either “Both” or “Called”, then this will match,
and the entire called NUA will be replaced with the corresponding NUA Out entry. In each case
the interface type to which the mapping applies can be selected from “ANY”, “LAPD”, “LAPB0”,
“LAPB1” “LAPB2” or “XOT”.
Using Text Commands
To configure the protocol switch NUA mappings via the command line use the x25map command.
To display a current protocol switch NUA mapping enter the command:
x25map ?
where is 0 - 19. Four separate commands are needed to set up a mapping. These
take the form:
x25map nuafrom t
x25map nuato
x25map interface
x25map ca_or_ci
where is the required entry number in the mapping table in each case.
The parameters and values are:
Parameter Values Equivalent Web Parameter
ca_or_ci 0,1,2 Called/Calling: 0=Both 1=Called
2=Calling
interface 0,1,2,3,4,12 Interface:
0=Any
1=LAPD
2=LAPB 0
3=LAPB 1
4=XOT
12=LAPB 2
nuafrom number NUA In
nuato number NUA out
For example:
x25map 13 nuafrom 9345
x25map 13 nuato 23421234567890
x25map 13 interface 4
x25map 13 ca_or_ci 2
