Interfaces Tab

Configuration > Networking > Interfaces

The Interfaces tab lists the interfaces for appliances selected in the appliance tree.

The All button displays all hardware and dynamic interfaces for the selected appliances.

Descriptions of the fields on this tab follow:

FieldDescription
Appliance NameName of the appliance for the interface.
NameName of the interface.
StatusStatus of the interface (up or down).
IP Address/MaskIP address for the interface.
Public IPPublic IP address for the interface.
SegmentName of the configured segment being used.
DHCPIndicates whether this interface’s IP address is obtained from the DHCP server. Displays as Yes, No, No data (not configured), or Invalid data (error condition).
SpeedCurrent interface speed state and setting.
DuplexCurrent interface duplex state and setting.
MTUMaximum number of packets being transmitted.
MAC AddressMAC address applied to the interface.
SNMP IfIndexIndex number of the network interface.
  • Best practice is to assign static IP addresses to management interfaces to preserve their reachability.

  • Duplex should never display as half duplex after auto-negotiation. If it does, performance issues and dropped connections will occur on the appliance. To resolve, check the cabling on the appliance and the ports on the adjacent switch or router.

  • To directly change interface parameters for a particular appliance, click the corresponding edit icon, which opens the Interfaces dialog box for the appliance.

  • To change the IP address for a lan or wan interface, either use the Appliance Manager Configuration > System & Networking > Deployment page or the CLI (Command Line Interface).

  • To change the IP address for mgmt0, either use the Appliance Manager Administration > Basic Settings > Hostname/IP page or the CLI.

Terminology

InterfaceDescription
blanBonded LAN interfaces (as in lan0 + lan1).
bvi0Bridge Virtual Interface. When the appliance is deployed in-line (Bridge mode), it is the routed interface that represents the bridging of wan0 and lan0.
bwanBonded WAN interfaces (as in wan0 + wan1).
tlan10-Gbps fiber LAN interface.
twan10-Gbps fiber WAN interface.

Interfaces Edit Row

Use this dialog box to change interface configurations for the appliance.

The All Interfaces button displays all interfaces for the appliance, including both assigned and unassigned hardware interfaces. MAC addresses indicate assigned interfaces.

Descriptions of the fields on this dialog box follow:

Hardware

FieldDescription
NameName of the interface.
AdminAdmin status of the interface (up or down). Click this field to change the value.
StatusStatus of the interface (up or down).
IP Address/MaskIP address for the interface. If the address is blue, you can click it to open the Deployment dialog box, from which you can change IP addresses/masks.
Public IPPublic IP address for the interface.
SegmentName of the configured segment being used.
Speed (Mbps) / DuplexCurrent interface speed and duplex settings. auto means auto-negotiation, which is the process by which terminating devices automatically negotiate for maximum bandwidth.
StateCurrent interface speed and duplex states.
MTUMaximum number of packets being transmitted. Click this field to change the value.
MACMAC address applied to the interface. To unassign the MAC address, click the field and select Unassigned.
SNMP IfIndexIndex number of the network interface.

Dynamic

FieldDescription
NameName of the interface.
StatusStatus of the interface (up or down).
IP Address/MaskIP address for the interface. If the address is blue, you can click it to open the Deployment dialog box, from which you can change IP addresses/masks.
SegmentName of the configured segment being used.
MTUMaximum number of packets being transmitted.
SNMP IfIndexIndex number of the network interface.
  • As a best practice, assign static IP addresses to management interfaces to preserve their reachability.

  • Speed (Mbps) / Duplex should never display as half duplex after auto-negotiation. If it does, performance issues and dropped connections will occur on the appliance. To resolve, check the cabling on the appliance and the ports on the adjacent switch or router.

  • To change the IP address for a lan or wan interface, either use the Appliance Manager Configuration > System & Networking > Deployment page or the CLI (Command Line Interface).
