Port Details

To view port details, double-click its row in the Interfaces table or click its overflow menu and select View Port:

The Details page is divided into three sections:

For information about the other pages available under Port Info, see Port Pages.

Port Details

TIP: The information listed in the portal is a relatively small subset of what is available.

To get full details about a port, use the GetInterfacePhysical API call.

Details

This section lists the interface ID, time created and updated, and information about the data center in which the port is located.

Device and Media

This section describes the physical device used for your connection.

Device Name

The device name has the following format: <router type><number>.<PoP ID>.

The router type is one of the following:

CFR
Core Fabric Router.
These routers are large and can support many 40 Gbps and 100 Gbps connections. Our CFR hardware is either Juniper QFX10k series or Cisco NCS5500 series.
EFR
Edge Fabric Router.
These routers are usually smaller. If the PoP already has a CFR setup, the EFR typically handles the 1 Gbps connections. At smaller sites, EFR can support a limited number of 100 Gbps connections.

For more information about device hardware, such as make and model, use the GetInterfacePhysical API call.

Interface

The interface name has the following format: type-fpc/pic/port.

Type
  • xe: 10 gigabit Ethernet interface
  • et: 100 and 40 Gigabit Ethernet interface
  • ge: Gigabit Ethernet interface
  • ae: Aggregated Ethernet interface
FPC
The slot number in which the FPC (flexible PIC concentrator) or DPC (dense port concentrator) line card is installed.
PIC
The PIC (physical interface card) location number on the FPC.
Port
The port number on the PIC or DPC.

For more information, see Juniper - Interface Naming Overview.

Speed/Media

The speed and optic you selected when creating the port.

Demarc LOA Information

The demarc LOA information specifies connection placement, including:

  • Panel
  • Module
  • Position

How this information is formatted varies depending on the site and hardware used.

Availability Zone

The availability zone signifies device diversity. Provisioning connections across availability zones builds redundancy in your network.

Single Gigabit Port Details

The following fields are only available for 1 Gbps ports.

Autonegotiation

When you create the port, you have the option to toggle autonegotiation on or off. You can also toggle it on or off when editing the port.

Autonegotiation is enabled by default. You can toggle it off for troubleshooting purposes or if you are connecting to a device operating in full-duplex mode.

NOTE: While autonegotiation is togglable on 1Gbps interfaces, it is also enabled on all 10Gbps and larger interfaces.

By default, link mode is set to auto. However, in some cases you can request that this be set to full duplex.

States

  • Row

    • State
    • Description
  • Row

    • Status

    • Status can have the following values:

      • Active

      • Deleted

      • Provisioning

        NOTE: On rare occasions, you might order a port at a location in which there is a temporary lack of pre-configured ports. When this happens, your port remains in the Provisioning state for 1-3 business days as we manually complete its configuration.

        An informational message should appear in the portal as you create the port letting you know about any lead times before you proceed.

  • Row

    • Admin

    • The Admin state refers to whether the router is enabled (Up) or disabled (Down).

      This is separate from the Enabled state, but they typically correspond with each other.

  • Row

    • Operational
    • The Operational state is read from your router and refers to the state of your cross connect link.
  • Row

    • Last Flap
    • This indicates the last recorded route flap. Route flapping can be caused by a variety of hardware, software, and connection errors.
  • Row

    • Billing

    • Charges begin to accrue 24 hours after you create a port (allowing you to cancel your order without incurring costs). Billing begins 15 days after the port is created.

      This field tells you how many days you have until billing begins. After 15 days, the status is updated to Active.

      TIP: Hover over Active to see the date that billing started.
  • Row

    • Enabled
    • This field indicates whether the port is enabled or disabled. For information on disabling ports, see Disable an Interface.

Optical Light Levels

Fiber optic connections work by translating binary data into light. The light is then transmitted through fiber cabling using different pulses, wavelengths, and intensity to convey that data.

The optical light level is the strength of that light when it is transmitted on one end and received on the other.

Optical light levels are measured in terms of transmitted power (TX) and received power (RX). Light lanes are the electrical lanes in the optic interface. The example below is a 40G optic, which has four lanes:

alt_text

When working correctly, the optical signal strength should fall within a certain power range. A green dot next to the RX/TX value indicates a healthy connection; a red dot indicates that either the optic levels are outside the acceptable range or that the cross connect has not been installed yet:

alt_text

  • Optical power that is too high can saturate the receiver and prevent a clean decode, resulting in errors. This is typically caused by the wrong type of optic, a too-short fiber span, or an active device in the path (such as an amplifier or DWDM transponder).

  • Optical power that is too low can result in slow connections, connections that won’t pass data, and connections that might not link at all. This is typically caused by unseated or dirty patches, a bad cross connection, or a longer fiber span than expected.

    If your optical light levels are consistently too low, you can have the patches cleaned, scoped, and replaced as needed.

NOTE: The acceptable range is different depending on the hardware. The high/low thresholds are included in the GetInterfacePhysical API response.

Active VCs

The Active VCs table lists all the virtual circuits attached to the port. You cannot delete a port if it has virtual circuits associated with it.
