Interfaces Tab

Configuration > Networking > Interfaces

The Interfaces tab lists the interfaces for appliances selected in the appliance tree. Fields available in the table depends on the selected filter button that is located immediately above the table.

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

Descriptions of the fields on this tab (All, Hardware, Dynamic, USB LTE) 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.
Type Port type (RJ45 or SFP). Drop-down box appears on interfaces with Combo ports. RJ45 is the default for Combo port.

NOTE: Combo ports apply to hardware interfaces only. Combo ports are not applicable to VLANs (virtual interfaces), so in those cases, this field appears blank.
  • 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.

Descriptions of the fields on this tab (PoE) follow:

Field Description
Appliance Name of the appliance for the interface.
Name Name of the interface.
PoE Config Power mode of the PoE interface.
PoE Status Enable status of the interface.
Priority Priority status of the interface (dynamic or static).
PoE Class Power class of the interface.
Voltage (V) Total voltage available on the appliance.
Current (A) Total current available on the appliance.
Power (W) Total power available on the appliance.

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.

PoE (Power Over Ethernet)

This table appears only for interfaces that support PoE.

Field Description
Edit Click to open the PoE Configuation Dialog box.
Name Name of the interface.
PoE Config Enabled status of the interface.
PoE Status Detection status. Settings include Searching, Delivering, or Disabled.
Priority Priority status. Priority determines the interfaces that receive power when power is over-subscribed on the appliance. Setting of 0 denotes highest priority.
PoE Class Power class of the interface.
Voltage (V) Total voltage available on the appliance.
Current (A) Total current available on the appliance.
Power (W) Total power available on the appliance.

Interfaces Dialog Box

The dialog box that appears depends on the selected filter button located immediately above the table.

  • When all, Hardware, Dynamic, or USB LTE is selected, the Interfaces dialog box appears. Use this dialog box to change configurations for the specified interface.

  • When PoE is selected, the PoE Configuration dialog box appears. Use this dialog box to modify the configuration interfaces on the specified 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.
Type Port type (RJ45 or SFP). Drop-down box appears on interfaces with Combo ports. RJ45 is the default for Combo port.

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.

PoE Configuration Dialog Box

The PoE Configuration dialog box modifies the configuration on interfaces located on the specified appliance. Configuration parameters include:

Power Mode: Specifies power management and priority parameters for appliance PoE interfaces. The following mode options are available:

  • Dynamic, without pre-allocation and no priority
  • Static, no priority
  • Dynamic with pre-allocation and no priority
  • Dynamic with pre-allocation and priority
  • Static with priority
  • Dynamic without pre-allocation and with priority

Individual Power Mode settings include:

Dynamic Mode: Power budget calculations are performed based on power that Powered Devices are currently consuming.

Static Mode: Power budget calculations are performed based on the class of the Powered Devices. Power consumption by Powered Devices is not considered.

Pre-Allocation: When connecting a new Powered Device, power budget calculations are based on the maximum power consumption of the class. If the sum of the current power allocated and the maximum power of the class is outside this budget, the device is not powered. When Pre-Allocation is disabled, the device is allowed to connect and make decisions based on consumption.

Port Limits: Individual ports can have maximum power draw limits set. Ports that exceed the power limit are be denied power.

Interface: The name of the interface modified by corresponding parameter settings.

Enable PoE: Specifies the PoE enable status of the correlated interface.

Priority: Specifies the priority status of the correlated interface. Priority determines the interfaces that receive power when power is over-subscribed on the appliance. (Priority settings are hidden when the selected power mode includes no priority).

Max Power (W): Configures the maximum power available to the corresponding interface.
