Cisco gateway cannot be added to VNQM

When trying to add a Cisco gateway to VNQM, the gateway cannot be added and VNQM displays an error that this device is not a gateway as similarly shown below:

• OIDs required by VNQM to add a gateway media are not present in the device MIBs.

The following OIDs are required:

// ISDN-MIB - isdnSignalingGetIndex
SnmpValueType ("1.3.6.1.2.1.10.20.1.3.1.0", SnmpValueType.INTEGER)

// DIAL-CONTROL-MIB:callHistory -callHistoryTableMaxLength
SnmpValueType ("1.3.6.1.2.1.10.21.1.4.1.0", SnmpValueType.INTEGER)

// IF-MIB:ifTableLastChange 
SnmpValueType>("1.3.6.1.2.1.31.1.5.0", SnmpValueType.TIMETICKS)


The wizard executes one “detector” job and this process:

1. At first, it checks whether  IsSnmpA is available by the presence of the following OID:
   • SysContactOid = "1.3.6.1.2.1.1.4.0"
2. Then, it checks for MediaGatewayOIDs:

• //ISDN-MIB - isdnSignalingGetIndex

"1.3.6.1.2.1.10.20.1.3.1.0", SnmpValueType.INTEGER,

• // DIAL-CONTROL-MIB:callHistory -callHistoryTableMaxLength

"1.3.6.1.2.1.10.21.1.4.1.0", SnmpValueType.INTEGER,

• // IF-MIB:ifTableLastChange 

"1.3.6.1.2.1.31.1.5.0", SnmpValueType.TIMETICKS

If all of the OIDs are present and the values have the correct type (SnmpValueType), the device is defined as a valid MediaGateway which can be added as a gateway.

Refer to the following VNQM documentation for the list of OIDs from the ccmGatewayTable.
