Guidelines for setting up VLANs in Data ONTAP
VLANs in Data ONTAP are implemented in compliance with the IEEE
802.1Q standard. You should keep these guidelines in mind when setting up VLANs in Data ONTAP:
- You cannot set up VLANs using the setup procedure. You must use the command line or the FilerView interface to create, change, or destroy VLANs.
- You must add the commands to create VLANs on your storage system to the /etc/rc file to make the VLANs persistent across reboots.
- You can create any number of VLANs on a NIC (supporting IEEE 802.1Q) on your storage system. However, Data ONTAP imposes a limit on the number of interfaces (including physical, vif, vlan, vh, and loopback interfaces) per storage system. See New maximum number of network interfaces for more information.
- You can create VLANs on physical interfaces and vifs.
- You can configure IPv4 and IPv6 addresses on a VLAN interface.
- You can use VLANs to support packets of different Maximum Transmission Unit (MTU) sizes on the same network interface. If a network interface is a member of multiple VLANs, you can specify different MTU sizes for individual VLANs.
- You can assign an identification number from 1 to 4094 to a VLAN.
- You must ensure that the interface on your storage system is also a member of its partner's VLANs in a cluster failover pair.
- You cannot configure any parameters except mediatype for the physical network interface configured to handle VLANs.
