NPM v10.7 gets VLAN information out of the box and works well for non-stacked Alcatel switches. However, the OIDs that provide VLAN information has been implemented slightly differently by Alcatel for stacked switches. The attached set of GET TABLE pollers display the VLAN information for stacked switches, and all of them use ifIndex as the label. You can also create additional pollers using the OIDs in the MIB-2 ifTable while choosing ifIndex as the label if you want to display things like interface description. You would have to add a 'Tabular Universal Device Poller' resource to your Node Details view to display the results of these pollers.
