# SNMP command executed: /usr/bin/snmpwalk -M /usr/local/snmp/mibs -v2c -c XXXXXXXXX xx.xx.xxx.xx:161 ARUBA-MIB::wlsxEnterpriseMibModules.4.1.1 
ARUBA-MIB::wlsxEnterpriseMibModules.4.1.1.0 = Gauge32: 4

.1.3.6.1.4.1.14823.2.2.1.4.1.1.0 = Gauge32: 5

The vendor cert "Aruba Switch Overview" shows the following:

Number Users

(wlsxTotalNumOfUsers/2015291)*100

Environment

NetOps Performance Management 20.2

Resolution

A vendor cert extension must be done:

 

Do a REST PUT against the following URL: http://<DA>:8581/typecatalog/certifications/snmp/extension/ArubaSwitchOverviewMib

 

The syntax should be as follows:

<!-- Auto-generated by the type catalog local manager. -->
<DataModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" namespace="http://im.ca.com/certifications/snmp" xsi:noNamespaceSchemaLocation="SNMPCertificationFacet.xsd">
<Author>CA</Author>
<Version>1.0</Version>
<FacetType name="ArubaSwitchOverviewMib" descriptorClass="com.ca.im.core.datamodel.certs.CertificationFacetDescriptorImpl">
<FacetOf namespace="http://im.ca.com/core" name="Item"/>
<Expressions>
<ExpressionGroup destCert="{http://im.ca.com/normalizer}NormalizedMobileSwitchAPInfo" name="ArubaSwitchOverviewMibDS">
<Expression destAttr="NumUsers">wlsxTotalNumOfUsers</Expression>
</ExpressionGroup>
</Expressions>
</FacetType>
</DataModel>

 

This gives the number of users from the mib object rather than a calculated number
