Interface and VLAN count recommendations

Interface count recommendations

We recommend monitoring up to 10000 interfaces in a single installation. If the count exceeds 10000, it will be efficient to increase the monitoring interval of those interfaces. Adding more interfaces will directly impact the overall performance of the product.


  1. Interfaces that have no data collection for the last 30 days will be automatically unmanaged and marked as 'Idle Interfaces' under the Interfaces Inventory page in VLAN discovery tool.
  2. You can avoid the addition of unnecessary interfaces by choosing appropriate criteria and conditions in the Interface Discovery page.

VLAN count recommendations

To avoid any hindrance in the performance of the product, OpManager limits the count of VLANs discovered to a maximum of 3000. New VLANs will not be allowed to be discovered in OpManager post the specified limit.
