index_order ignores valid ifAlias

[ns]

For some reason, my data source always choses ifIndex as its Index Type even when there is a valid ifAlias. Here's my interface.xml:

Code: Select all

 <name>Get SNMP Interfaces</name>
        <description>Queries a host for a list of monitorable interfaces</description>
        <oid_index>.1.3.6.1.2.1.2.2.1.1</oid_index>
        <oid_num_indexes>.1.3.6.1.2.1.2.1.0</oid_num_indexes>
        <index_order>ifAlias:ifIndex:ifDescr</index_order>
        <index_order_type>numeric</index_order_type>
        <index_title_format>|chosen_order_field|</index_title_format>

...
               <ifAlias>
                        <name>Alias (IF-MIB)</name>
                        <method>walk</method>
                        <source>value</source>
                        <direction>input</direction>
                        <oid>.1.3.6.1.2.1.31.1.1.1.18</oid>
                </ifAlias>

And snmpwalk:

Code: Select all

snmpwalk -v 2c -c ******** ******* ifAlias
IF-MIB::ifAlias.1 = STRING: test
IF-MIB::ifAlias.2 = STRING: ""
IF-MIB::ifAlias.3 = STRING: ""
IF-MIB::ifAlias.4 = STRING: ""
IF-MIB::ifAlias.5 = STRING:

I've also reloaded the xml file with no luck. Any ideas?
