The following table list problems that may occur while attempting to bootp devices using the SDM, along with their potential solutions.

The Troubleshooting Information topics list problems that may occur while using the SDM, along with their possible solutions.

If trying the solutions listed here does not resolve the problem, contact the Technical Assistance Center (TAC), which is on call 24 hours a day, 7 days a week.

ProblemPossible Solution
Unknown bootp request received on the SDM Network Events list.This will occur on SDMs where the second network card has been configured for DHCP,but is not receiving a DHCP reply. If this is not intended, set the second card to a static IP address,or disable the card if it is not in use.
Problems performing a bootp operation on a device.The most common cause of bootp issues is an invalid network configuration. Please ensure that all of the following conditions are met:
  • Verify that you can ping the device from the SDM to confirm there is no network connectivity issue.
  • No other bootp servers are active on the network.
  • Any router between the SDM and the target device is properly configured to pass bootp messages to the SDM.
  • An IP Helper is configured on the intermediate routers to facilitate data transfer of bootp messages to the SDM server.
  • Firewall software is not blocking port 67, and no other application that uses port 67 is running on the same machine as the SDM.
  • Verify that bootp is set to Unconditional in the device's SDM properties on the Administration tab.
  • The MAC address of the device in the SDM matches the device's actual MAC address.
  • The SDM is not pointing to an invalid or non-responsive DNS server. (If this condition exists,it will cause a delay in the Boot Protocol Process in Progress event,which causes the bootp process to timeout.)
  • Multiple default gateways are not in use on the SDM. (If the SDM is configured with multiple default gateways, the bootp reply may be sent through a gateway that does not have a route to the device. It is not recommended to use multiple default gateways on the SDM.)
