Table 3: QFabric System Terms (continued)
Definition Term
Private collection of routing tables, interfaces, and routing protocol parameters
unique to a specific customer. The set of interfaces is contained in the routing
tables, and the routing protocol parameters control the information in the
routing tables.
(See also virtual private network .)
routing instance
Set of one or more Node devices that connect to servers or storage devices. server Node group
Unique Layer 2 broadcast domain for a set of ports selected from the
components available in a partition. VLANs allow manual segmentation of
larger Layer 2 networks and help to restrict access to network resources. To
interconnect VLANs, Layer 3 routing is required. virtual LAN (VLAN)
Layer 3 routing domain within a partition. VPNs maintain privacy with a
tunneling protocol, encryption, and security procedures. In a QFabric system,
a Layer 3 VPN is configured as a
routing instance .

Four-Level Interface Naming Convention
When you configure an interface on the QFabric system, the interface name needs to
follow a four-level naming convention that enables you to identify an interface as part
of either a Node device or a Node group. Include the name of the network or server Node
group at the beginning of the interface name.
The four-level interface naming convention is:
device-name : type-fpc/pic/port
where device-name is the name of the Node device or Node group. The remainder of the
naming convention elements are the same as those in the QFX3500 switch interface
naming convention.
