CISCO AUX BACK-TO-BACK 实例

[作者:中国IT实验室收集整… 来源:不详 时间:2012-11-15我来说两句

  Click on the routers in the topology below to vIEw their configurations.
  
  router 2500 AUX----NULL MODEN CABLE-----ROUTER 2500 AUX
  
  Before You Begin
  This configuration has Cisco 2500-serIEs routers back-to-back using the async AUX port. The Cisco AUX port is connected to another CiSCo AUX port running PPP. The connection has been configured to allow IP for a permanent connection.
  
  IngredIEnts
  For this recipe, you need the following:
  
  A null modem cable.
  
  You may also need an RJ45-to-DB25 adapter converter. For more information on cables, see the Cables documentation.

  Debug and Show Commands to Use for Troubleshooting
  Check under line aux 0:
  Issue the show line aux 0 command.
  
  Verify that all signals are up. For example, CTS, RTS, DTR, CD. If nothing appears next to them, they are up. If "No" appears next to them (for example, No-CTS), it means they are down.

  Use the show line command to determine the async interface of the AUX ports. Though most routers have the AUX port as interface async 1, Access servers have the AUX port interface after the tty lines. For example, if your router has 16 async/modem lines, then the AUX port is line 17. In this case, the AUX port must be configured on interface async 17. Configure the AUX port based on the show line outputs. The example below verifIEs that the AUX port is on int async 1.
  
  Router1#show line
  Tty Typ Tx/Rx A Modem Roty AccO AccI Uses Noise Overruns
  * 0 CTY - - - - - 0 0 0/0
  A 1 AUX 38400/38400 - inout - - - 0 0 0/0
  2 VTY - - - - - 0 0 0/0
  3 VTY - - - - - 0 0 0/0
  4 VTY - - - - - 0 0 0/0
  5 VTY - - - - - 0 0 0/0
  6 VTY - - - - - 0 0 0/0
  Use these debug commands to verify that the link comes up correctly:
  
  debug ppp negotiation - To display information on PPP traffic and exchanges while negotiating Link Control Protocol (LCP), Authentication, and Network Control Protocol (NCP). A successful PPP negotiation will first open the LCP state, then Authenticate, and finally negotiate NCP. If CONFREQs are being sent out, but no CONFACKs being received, check that the cabling is correct and whether the correct line (interface async x) is configured.
  debug ppp authentication - To display PPP authentication protocol messages, including Challenge Handshake Authentication Protocol (CHAP) packet exchanges and Password Authentication Protocol (PAP) exchanges.
  debug ppp error - To display protocol errors and error statistics associated with PPP connection negotiation and operation.
  Before attempting any of the above debug commands, please see Important Information on Debug Commands.
