Add an Interface

You must be a system administrator to add a network interface. Take the following steps:

  1. Go to Administration > System.
  2. Under Interfaces select Add.
    The Create New Interface dialog displays.
  3. Configure the following parameters:
    Table 1. Interface Parameters
    FieldDescription
    NameName of the interface.
    ModeDescribes 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 ExtremeCloud IQ Controller management port.
    VLAN IDID for the virtual network.
    TaggedIndicates 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.
    PortPhysical port on the ExtremeCloud IQ Controller for the interface.
    Enable Device RegistrationEnable or disable AP registration through this interface. When enabled, wireless APs use this port for discovery and registration. Other ExtremeCloud IQ Controllers can use this port to enable inter-ExtremeCloud IQ Controller device mobility if this port is configured to use SLP or the ExtremeCloud IQ Controller is running as a manager and SLP is the discovery protocol used by the agents.
    Management TrafficEnable or disable Management Traffic through this interface. Enabling management provides access to SNMP (v1/v2c, v3), SSH, and HTTPs management interfaces.
    MTUMaximum 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.
    FQDNFully-Qualified Domain Name
    DHCP ServerConfigure the Interface as a DHCP Server. 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 ExtremeCloud IQ Controller is used for managing IP addresses.
    Note: This setting differs from DHCP Client on the admin interface. Here you are configuring the controller as a DHCP server. You can also configure the admin interface as a DHCP client.
