110 CHAPTER 5: PROBLEM SOLVINGSolving Problems With an SNMP Network ManagementApplicationThe SNMP network management application cannot accessthe stack. Check that: The stack’s IP address, subnet mask and default router arecorrectly configured, using either: The command line interface — refer to “Displaying the IPInformation” on page 52. The web interface — refer to “Management Address” onpage 85. The stack’s IP address is correctly recorded by the managementapplication. For information on how to do this, refer to thedocumentation that accompanies the application. You can access other devices. If you cannot access any otherdevices, there may be a problem with your SNMP networkmanagement application or management station.The SNMP network management application can no longeraccess the stack. Check that the port through which you are tryingto access the stack has not been disabled. If it is enabled, check theconnections and network cabling at the port. Try accessing the stackthrough a different port. If you can now access the stack, a problemwith the original port is indicated. Re-examine the connections andcabling.Possibly there is a network problem preventing you from accessingthe stack over the network. Try accessing the stack through theconsole port of one of the hubs, and reset the stack.
