In questa configurazione, due diverse risorse X.25 (abbiamo utilizzato dspu-host per simulare i dispositivi terminali in questa configurazione). Per ulteriori informazioni sull'unità fisica a valle (DSPU), fare riferimento ai seguenti documenti:
Questi due dispositivi terminali comunicano con adattatori diversi nel sito mainframe su X.25. Le risorse X.25 remote sono state configurate per indirizzi di destinazione diversi (in lunghezze e indirizzi diversi). Qualsiasi chiamata in arrivo il cui indirizzo di destinazione X.121 corrisponde al "sottoindirizzo dlsw qllc" del router viene inviata a Data Link Switching Plus (DLSw+) (con ID.STN IND). Quando DLSw+ riceve una richiesta di informazioni su un indirizzo MAC virtuale del pool, il codice QLLC (Qualified Logical Link Control) tenta di impostare un circuito virtuale (VC) sull'indirizzo X.121 mappato all'indirizzo MAC virtuale specificato. Se viene ricevuta una chiamata in arrivo, QLLC invia a DLSw+ un ID.STN.IND con un indirizzo MAC virtuale dal pool.
Nessun requisito specifico previsto per questo documento.
Le informazioni fornite in questo documento si basano sulle versioni software e hardware:
Il software Cisco IOS® versione 12.2(6a) è stato usato in Pathos (Cisco 2612)
