Issue/Introduction
How to use the DCM timeout value to enable NCM captures to complete successfully.
Occasionally there may be a requirement to increase the DCM timeout in order to enable an NCM capture to complete successfully.
By default the DCM timeout is set to 3 seconds and this may not be enough time for the device response to be received by Spectrum.
The DCM timeout value dictates how long Spectrum waits for a response after the SNMP set is sent for before it triggers the timeout error.
Increasing the DCM timeout means that Spectrum will wait longer from the time that it sends the SNMP set.
Resolution
To change the DCM timeout go to the CA Spectrum Modeling Information sub view on the information tab.
From here you can modify the DCM Timeout starting by double the ms value.
