Interface Properties

The following table provides details about Interface Properties.

Table 1. Interface Properties
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.
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.
Enable Device Registration	Enable or disable AP registration through this interface. When enabled, wireless APs use this port for discovery and registration. Other Universal Compute Appliances can use this port to enable inter-Universal Compute Appliance device mobility if this port is configured to use SLP or the Universal Compute Appliance is running as a manager and SLP is the discovery protocol used by the agents.
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.
Layer 3
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
DHCP	Dynamic Host Configuration Protocol allows network administrators to centrally manage and automate the assignment of IP addresses on the corporate network. DHCP sends a new IP address when a computer is plugged into a different place in the network. The protocol supports static or dynamic IP addresses and can dynamically reconfigure networks in which there are more computers than there are available IP addresses. Valid values are: None Local Server. Indicates that the Universal Compute Appliance is used for managing IP addresses.
VRRP	Supports load balancing and high-availability functions for the Universal Compute Platform cluster. IP Addresses Record the IP address relationship between the cluster‘s direct interfaces (ICC, Service/Data ports), VRRP, and external access. Priority VRRP uses priority settings as a mechanism to arbitrate mastery of the state of exchanges across members of the cluster. Best Practice: Designate node 1 as the highest priority, node 2 for second highest priority, and node 3 as the lowest priority. The same priority should be used across all services (ICC, Services). Router ID Allows segmentation of a routing domain. It is important to separate from any 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 segments. Note: In a stand-alone configuration, configure priority and router ID with a numeric value. However, in a stand-alone configuration, the specific value is not important. These attribute definitions are important in a multiple-node configuration.
