Chapter 3 Adding and Troubleshooting Devices Using Device Management
Checking and Viewing Device Credentials
You can also verify the RME device credentials in two other ways:
• Using the command line tool, cwcli inventory cda.
See Overview: cwcli inventory Command for further details.
• Using the Device Center (From CiscoWorks LMS Portal home page, Device Troubleshooting >
Device Center to launch Device Center).
See RME Device Center for further details.
Check Device Credentials Algorithm
Device Credential Verification verifies credentials that are device packages specific to a device type.
These device packages may have variations in CLI access and respond to different transport protocols.
Device credential verification uses the credentials stored in Device and Credential Repository and
validates these credentials against the corresponding device.
The following is the algorithm used to verify credentials for the device transport protocol:
• Read Community String
Read community string is verified by performing read operation via the SNMP transport library and
checking the result.
• Read/Write Community String
a. Read write community string is verified by performing snmpget operation on syslocation
variable.
b. snmpset is performed with the value returned in the previous step.
If the error message returned is,
–
snmpRspBadValue then the Read/Write community string is considered correct.
–
snmpRspNoSuchName then the Read/Write community string is considered wrong.
• Telnet Username and Password
Telnet username and password are verified by trying to login to the device using the Telnet transport
library. It also verifies if the attempt is successful.
• SSH Username and Password
SSH username and password are verified by trying to login to the device using the SSH transport
library. It also verifies if the attempt is successful.
• Telnet enable mode password
Enable mode password is verified while trying to establish connection using Telnet and entering the
enable mode. It also verifies if the attempt is successful.
• SSH enable mode password
Enable mode password is verified while trying to establish connection using SSH and entering the
enable mode. It also verifies if the attempt is successful.
After the device credentials are validated the result will be displayed and you can refresh to see the latest
status.
Note View Permission Report (Common Services > Server > Reports) to check if you have the required
privileges to perform this task.
