Beginning with Data ONTAP 7.3, storage systems, except for the smallest models, are no longer limited to 128 interfaces per storage system. Larger storage systems can accommodate from 256 to 1024 network interfaces per system depending on the system's memory and whether they are in a clustered, active-active configuration.
Run the sysconfig command and refer to the Memory size field displayed for your storage system's slot 0 system board to determine your storage system memory.
The new maximum number of network interfaces allowed for each system are shown in the following table. The total number of interfaces can include physical, vif, VLAN, vh, and loopback interfaces.
The number of physical interfaces depends on the storage system model. Up to 16 vifs may be supported by each storage system. The maximum number of vlans that can be supported equals the maximum number of network interfaces shown in the following table minus the total number of physical interfaces, vifs, vh, and loopback interfaces supported by the storage system.
