Create New Interface Settings

The following table provides interface properties for the settings in the Create New Interface window.

Table 1. Interface Field Descriptions
Field	Description
Name	Name of the interface.
Mode	Describes how traffic is forwarded on the interface topology. Options are: Physical - The topology is the native topology of a data plane and it represents the actual Ethernet ports. Management - The native topology of the Universal Compute Appliance management port. Routed - The controller is the routing gateway for the routed topology. Bridged at Controller - The user traffic is bridged (in the L2 sense) between wireless clients and the core network infrastructure. Bridged at AP - The user traffic is bridged locally at the AP without being redirected to the controller.
VLAN ID	ID for the virtual network.
Tagged	Indicates if the interface tags traffic. When traffic is tagged, the VLAN ID is inserted into the packet header to identify which VLAN the packet belongs to. Tagging can identify the port or interface to send a broadcast message to.
Port	Physical port on the Universal Compute Platform for the interface.
Management Traffic	Enable or disable Management Traffic through this interface. Enabling management provides access to SNMP (v1/v2c, v3), SSH, and HTTPs management interfaces.
MTU	Maximum Transmission Unit (MTU). Standard is 1500 bytes. Fixed value.
IP Address	For an Admin topology, the Layer 3 check box is selected automatically. The IP address is mandatory for a Physical topology. This allows for IP Interface and subnet configuration together with other networking services.
CIDR	CIDR field is used along with IP address field to find the IP address range.
FQDN	Fully-Qualified Domain Name
VRRP	This field lets you assign VRRP virtual IP addresses to this interface. For Managed Orchestration clusters, VRRP addresses support load balancing and high availability for cluster services. For Self-Orchestration standalone clusters, VRRP can be used to create an IP alias with access to the application management interface. To add a VRRP address, select Add, and configure the following: Address Enter the VRRP IP address. Note the following requirements: You can add up to ten VRRP addresses per data port. However, for ICC ports, you can add a single VRRP address only. To delete an address, select the adjacent icon. VRRP IPs must be on the same segment as the interface IPs. VRRP IP addresses must not overlap with any other address in the segment, including addresses assigned by the application. With clustered deployments, make sure to record the IP address relationship between the cluster‘s direct interfaces (ICC, Service/Data ports), VRRP, and external access. Comments An optional text comment for each VRRP address. Use the comment to describe how that VRRP address is used. Priority A numeric value (between 1-254) that determines mastery of the state of exchanges across cluster nodes. The value that you enter applies to all VRRP addresses on this port. As a best practice, note the following: On a single node, assign the same priority to all Service Set and ICC VRRP addresses. However, assign a different value on different cluster nodes. As a best practice, designate node 1 as highest priority, node 2 as second highest priority, node 3 as lower priority, and so on in descending order. Router ID A numeric value (between 1-255) that allows segmentation of a routing domain. The ID applies to all VRRP addresses on this port. Within a cluster, assign the same Router ID to the same VRRP addresses across the cluster. We recommend that you use a different Router ID for ICC VRRPs than for Service Set VRRPs. It is important to separate this VRRP config from other VRRP uses on the same network segment. The assigned value is arbitrary, but the value must not overlap when another VRRP usage is visible in the attached network segment. Note: The Priority and Router ID settings are important in multi-node clusters only. For Self-Orchestration standalone clusters, assign numeric values to each, but the specific values are not important.
