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.
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.
