Execution Errors 91

Error constructing target specification...hostname no longer valid?

The user was prompted for target slot/channels using the chassis selection dialog. After targets were selected, the construction of a target failed, probably because an IP host name could not be found in the hosts database even though the host name was valid at program initialization. (The host database has probably been changed or is no longer accessible.)

Target not responding because NMC is in a software download state. Please wait until software download is completed.

The NMC is being actively downloaded, or a download was initiated and not finished. It will not respond to SNMP requests until download is completed.

SNMP Get: <error>

An error occurred while IP Telephony Manager was issuing an SNMP operation: either a timeout or an SNMP protocol error. If it is a protocol error, the SNMP variable information in the error response can be seen in the IP Telephony Manager log (e.g., syslog).

SNMP Get-Next: <error>

An error occurred while IP Telephony Manager was issuing an SNMP operation: either a timeout or an SNMP protocol error. If it is a protocol error, the SNMP variable information in the error response can be seen in the IP Telephony Manager log (e.g., syslog).

SNMP Set: <error>

An error occurred while IP Telephony Manager was issuing an SNMP operation: either a timeout or an SNMP protocol error. If it is a protocol error, the SNMP variable information in the error response can be seen in the IP Telephony Manager log (e.g., syslog).
