Logical Interfaces Field DescriptionsNEW!

Use the data in the following table to use the Logical Interfaces tab and the Insert Logical Interfaces dialog. The available fields in the dialog differ depending on the type of core you select: layer 2 or ip.


Name	Description
Id	Specifies the index number that uniquely identifies this logical interface. This field displays on the Insert Logical Interfaces dialog only.
IfIndex	Specifies the index number that uniquely identifies this logical interface. This field is read-only. This field displays on the Logical Interfaces tab only.
Name	Specifies a name associated with this logical interface, which can be up to 64 characters. Note: If you do not assign a name when you configure virtual NNI links for Multi-Area boundary nodes for VSP 7400 Series, the system autogenerates the name and displays the name as `Virtual-link-x`, where `x` is the logical interface ID.
Type	Specifies the type of logical interface to create: Specify layer 2 for a Layer 2 core network that the tunnel will traverse. Specify ip for a Layer 3 core network that the tunnel will traverse.
DestIPAddr	Specifies the destination IP address for the IP-type logical interface.
DestIfIndex	Specifies the physical port or MultiLink Trunking (MLT) that the Layer 2 logical interface is connected to.
Vids	Specifies the list of VLANs that are associated with this logical interface.
PrimaryVid	Specifies the primary tunnel VLAN ID associated with this Layer 2 Intermediate-System-to-Intermediate-System (IS-IS) logical interface.
CircIndex	Identifies the IS-IS circuit created under the logical interface. This field displays on the Logical Interfaces tab only.
NextHopVrf	Displays the next-hop VRF name to reach the logical tunnel destination IP. This field displays on the Logical Interfaces tab only. You can use this field to specify the VRF to reach the logical tunnel destination IP associated with a parallel tunnel.
ISIS Mtu	Specifies the Maximum Transmission Unit (MTU) size in bytes for IS-IS packets that use this logical interface. The default value is 1600.
BfdEnable	Enables or disables BFD on an IS-IS Logical Interface.
SrcIPAddr	Configures an additional source address to use as the parallel tunnel to create a backup adjacency. Note: To use an IPsec-encrypted tunnel as the parallel tunnel ensure that you configure the same source IP address on the logical IS-IS interface and in the Fabric IPsec Gateway virtual machine.
Origin	Specifies the origin of the IS-IS logical interface configuration, either through Zero Touch Fabric Configuration (ZTF) or manual configuration (config) through CLI or EDM.
Multi-Area Virtual Link Note: Exception: only applies to VSP 7400 Series.	Enables (true) or disables (false) a Multi-area boundary node virtual NNI link on an IS-IS Logical Interface. The default is disabled.
