Port Details Pages
To view port details, double-click its row in the Interfaces table or click its overflow menu and select View Port:
For information about the Details page, see Port Details.
The statistics page presents graphical information on traffic, errors, and optics.
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.
- 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 an inadequate buffer size.
- The number of discarded packets in excess of the burst allowance (your committed rate).
- 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 information that is logged varies depending on the device. Common log messages are SNMP_TRAP_LINK_UP and SNMP_TRAP_LINK_DOWN, which are logged when an interface changes state.
Any optical light level warnings or alarms are also logged here.
The History page shows event logs specific to the interface.
Events that are logged include the following:
- When the interface was created
- The creation and deletion of virtual circuits
- LOA generation
- Disable and enable actions
- Any changes to the port name
Click Toggle Details to view more information about the event.
You can find the LOA and any service orders on the Documents page.
Click Upload File in the upper right to upload any related documents relevant to your network or port.
