Chapter 3 Adding and Troubleshooting Devices Using Device Management
Working With Pre-deployed Devices
If the ping fails because the:
• Device is an unknown host. The name service could not resolve the specified host name into an IP
address.
• Device is unreachable. Your local system is unable to determine a route to the device.
• Device is not responding. Your local system was able to determine a route to the device, but the ping
did not receive any responses to the ICMP echo-request packets it sent to the device.
Step 2 Open a Telnet session to the device to check its SNMP configuration.
If the device is not responding to the SNMP Get request packets from your server, make sure it has an
SNMP agent that is enabled and accessible using the community strings you specified.
Use etherfind or another packet analyzer to investigate the SNMP packet exchange between your server
and the SNMP agent on the device.
If the device does not support RFC 1213 (SNMP MIB II) attributes, it cannot be managed by RME.
Step 3 After you have corrected your device specification, your network connectivity, or both, resubmit the
device.
If you try to re-import a device without modifying its device credentials using Common Services >
Device and Credentials > Device Management, that device is not processed. Instead it is shown as a
duplicate device in the Device Import Status window.
You should resubmit the Pre-deployed device using RME > Devices > Device Management >
Pre-deployed Devices > Resubmit (button).
These tables describe the probable cause and the suggested action that needs to be taken when the
devices are in Pre-deployed state:
• PingUtility Determines That the Device is an Unknown Host (Table 3-6)
• Ping Utility Determines That the Device in Unreachable (Table 3-7)
• Device Does not Respond to an ICMPEcho Request Packet (Table 3-8)
• Device Does not Respond to an SNMP Get Request Packet (Table 3-9)
• Device Does not Support RFC 1213(SNMP MIB II) Attributes (Table 3-10)
The following table describes what to do if the Ping utility determines that the device is an unknown
host:
