Point-to-Point Connection Details Pages
To view the connection details, select Point to Points in the menu on the left. Click one of the table rows to view an overview of that connection. For complete information, click Details.
For information about the Details page, see Point-to-Point Connection Details.
Because a point-to-point connection is essentially two ports connected by a single virtual connection, the details page comprises a combination of the same information you would find on a port details page and virtual circuit details page.
Port A and Port Z
The Port A and Port Z pages provide details about the two ports in the point-to-point connection.
- Header Row
- The administrative status refers to whether the router is enabled (Up) or disabled (Down).
- Port ID
- A unique identifier for the source port that includes the metro in which the port is located.
- The speed and optic you selected when creating the connection. For more information, see LINK> The speed and optic values are the same between the source and destination ports.
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 Device-Info API call.
- CFR: Core Fabric Router
The interface name has the following format:
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.
- The Operational status is read from your router and refers to the state of your cross connect link.
- Information about where the connection is place in the data center. 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.
(1G connections only)
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.
You can also toggle this on or off when editing the connection.NOTE: While autonegotiation is togglable on 1Gbps interfaces, it is also enabled on all 10Gbps and larger interfaces.
- Last Flap
- This indicates the last recorded route flap. Route flapping can be caused by a variety of hardware, software, and connection errors.
- Graphical representation of network traffic over the last 24 hours.
Information about the data center in which the port is located.
In some cases, the data center information might be different between the customer and PacketFabric (for example, different sites on a shared campus).
As you scroll down the page, you will see graphical information on traffic, errors, and optics for the ports.
By default, you are shown metrics over the past 12 hours. You can use the drop-down menus to select a different time frame, or select Custom to specify a date and time range.
You can view the following traffic metrics. Hover to see TX and RX details.
- Header Row
- Row 1
- Bits per second
- How many bits of data were transmitted per second.
- Row 2
- Packets per second
- Total number of packets per second.
- Row 3
- Unicast Packets
- Unicast packets are sent from a single source to a single receiver. Most LAN and internet traffic is unicast packets. This includes TCP traffic.
- Row 4
- Broadcast Packets
- Broadcast packets are sent from a single source to all receivers on the connection. This includes ARP traffic.
- Row 5
- Multicast Packets
- Multicast packets are sent from one or more sources to one or more receivers. This includes UDP traffic.
Framing errors occur when a data frame is read at the wrong starting point or is not in the format expected.
Common causes include hardware issues (optic cables, serial ports, NIC), duplex mismatches, and mismatched settings between the serial port and device.
- Resource Errors
- The number of transmit drops. This typically indicates a buffer error or that packets are too large to add to the buffer.
- MTU Errors
- The number of packets whose size exceeded the interface MTU. This is an output error.
- CRC Errors
- CRC errors indicate data corruption. These can be caused by a faulty cable, PIC, or FPC.
- The number of packets ASIC’s RED mechanism drops from the input queue. This can indicate traffic congestion or inadequate buffer size.
- The number of discarded packets over the burst allowance (your committed rate). Our default burst size is 6250000 bytes.
- The number of frames that have been received and are smaller than the minimum frame size (64 bytes). These are typically caused by collisions
- The number of packets that spent so much time in memory that they have been automatically purged. This can indicate software and hardware malfunctions.
- Module Temperature
- We use commercial transceivers, which have a temperature range of approximately 0-70° C.
- Transmit and Receive Power
- Transceiver power over time.
The statistics page presents a graphical view of the network traffic for the EPL connecting the to ports.
By default, you are shown metrics over the past hour. You can use the drop-down menus to select a different time frame, or select Enter Date Range to specify a date and time range.
You can view traffic in bits per second or packets per second.
The History page shows event logs specific to the connection.
Events that are logged include the following:
- When the interfaces were created
- LOA generation
- Any changes to the connection name
Click Toggle Details to view more information about the event.
From here you can find and download the LOA and any service orders.
