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:

Field	Description
Appliance	Name of the appliance for the interface.
Name	Name of the interface.
Status	Status of the interface (up or down).
LACP Status	Link aggregation status of the interface (up or down). This status applies only to bonded interfaces (blan0, blan1, bwan0, and bwan1). This field is displayed only if the channel group is in LACP mode.
IP Address/Mask	IP address for the interface.
Public IP	Public IP address for the interface.
Segment	Name of the configured segment being used.
DHCP	Indicates 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).
Speed	Current interface speed state and setting.
Duplex	Current interface duplex state and setting.
MTU	Maximum number of packets being transmitted.
MAC Address	MAC address applied to the interface.
SNMP IfIndex	Index 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

Interface	Description
blan	Bonded LAN interfaces (as in lan0 + lan1).
bvi0	Bridge Virtual Interface. When the appliance is deployed in-line (Bridge mode), it is the routed interface that represents the bridging of wan0 and lan0.
bwan	Bonded WAN interfaces (as in wan0 + wan1).
tlan	10-Gbps fiber LAN interface.
twan	10-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

Field	Description
Name	Name of the interface.
Admin	Admin status of the interface (up or down). Click this field to change the value.
Status	Status of the interface (up or down).
IP Address/Mask	IP 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 IP	Public IP address for the interface.
Segment	Name of the configured segment being used.
Speed (Mbps) / Duplex	Current interface speed and duplex settings. auto means auto-negotiation, which is the process by which terminating devices automatically negotiate for maximum bandwidth.
State	Current interface speed and duplex states.
MTU	Maximum number of packets being transmitted. Click this field to change the value.
MAC	MAC address applied to the interface. To unassign the MAC address, click the field and select Unassigned.
SNMP IfIndex	Index number of the network interface.

Dynamic

Field	Description
Name	Name of the interface.
Status	Status of the interface (up or down).
LACP Status	Link aggregation status of the interface (up or down). This status applies only to bonded interfaces (blan0, blan1, bwan0, and bwan1). This field is displayed only if the channel group is in LACP mode.
IP Address/Mask	IP 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.
Segment	Name of the configured segment being used.
MTU	Maximum number of packets being transmitted.
SNMP IfIndex	Index 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).
To change the IP address for mgmt0, either use the Appliance Manager Administration > Basic Settings > Hostname/IP page or the CLI.
