Environment

VMware Smart Assurance - NCM

Resolution

NCM identifies serial number of cisco device with the following details.

If communication method is SNMP, results will be based on the following OID:
.1.3.6.1.2.1.47.1.1.1.1.11.X: <serial number>


If communication method is Telnet/SSH:
In "show version" command output - entry for "Processor board ID" is considered serial number.

 

Additional Information

"Pull System Properties" operation collects the Serial Number of the device.
As per Cisco IOS driver code - If SNMP Credentials are set at device end during discovery/ available in "Device Properties -> Communication", SNMP is given precedence for "Pull SystemProperties" even if the Mechanism set is "SSH".
