Configure NUA mappings
Protocol switch NUA mappings allow you to redirect specified NUAs to alternative NUAs for switched
X.25 calls. Up to 20 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 only the rightmost digits in the NUA are
compared with the table entry.
ÉWeb
1. Go to Configuration > Network > Protocol Switch > NUA Mappings.
The NUAMappings page displays a table with four columns in which you can specify the NUA
In values, corresponding NUA Out values, to which interfaces the mappings should be applied,
and whether the mapping should apply if the router 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, 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.
2. Click Add to add each NUAto mapping.
3. Click Apply.
