Logical Fields

The Net Protocol Suite supports the following Logical Fields:

Analyzer speed

Traffic speed on the Port.

This specifies the bit rate of the item (1G, 2G, 4G, 8G, 10G, 16G, 25G, 32G, 40G, 50G, 100G).

Brief

The transport function names listed in an exchange

Command Status

The status of the packet if the packet is a command, such as reject or complete. For example, specifies SCSI command status (Good, Check condition, …).

Count

The number of repeated order items. This specifies the number of instances for items with a repeated count (AN, Training, Ordered Sets).

Current State

Specifies the analyzer sequencer state number at the time the item was captured.

Data Length

The length of the data in the frame, if it is a data frame, such as FCP Data frames. This specifies the length of the data payload in byte For frame items.

Duration Time

The amount of time it takes to receive all of the data of the item. Time is specified in nanoseconds.

Ethernet Frame

Value if this field is “Ethernet” for Ethernet frames and is Null for other frames.

Ethernet Tag

The Tag name of the frame such as VXLAN.

It shows string of Ethernet tags (if any), otherwise is null. Ethernet tags can be “ISL”, “VXLAN”, “GRE”, “NVGRE”.

EVPD

The “EVPD” field value in an inquiry SCSI command frame. This is “EVPD=True”, if the EVPD in SCSI Inquiry bit is 1; otherwise, it is null.

Exchange Status

The exchange status for each command. This specifies the exchange status in general. The exchange status can be one of the following values: 0x2: Success; 0x0x1: Fail; 0x0: Incomplete.

FC Frame

Link protocol name such as FC. It is “FC” for FC frames; otherwise, it is null.

FEC Status

The FEC status of the frame. This is “BASE-R FEC” for FEC 2112, and “Reed-Solomon FEC” for Reed Solomon FEC; otherwise, it is null.

FICON Non-Zero status flags

FICON status flag values.

  • This is a string that shows the name of flags that are on (value is 1) the status flag of the FICON frame; otherwise, it is null. This field is applicable only for FICON frames.

  • Status flags are “FFC”, “CI”, “CR”, “LRI”, and “RV”.

Fragment Offset

Displays the “offset” field value in the IP header. The IP “Fragment Offset” field is expressed in bytes.

Jammer Port Name

Jammer Port Name.

This field is applicable to the AJA port configuration. It is “Before Jam” for frames that were captured before the jamming action; it is “After Jam” for frames that were captured after jamming.

Lane No

The Lane number of the item. It specifies the physical lane number for link training items at 40/50/100G.

Latency

The time between the first frame of the exchange and the last frame of the exchange.

  • This value is valid for first frame of an exchange; it is not applicable for other frames of the exchange.

  • The latency time of an exchange is expressed in nanoseconds.

Link Function Name

Link Function name. This is a string that includes a decoded abstract of item and shows Protocol and/or Frame type.

Link Service

Basic link ABTS type & Link ACK.

  • This is applicable for FC Basic link service and the Link control frame.

  • It specifies a string that shows the Basic Link Service/Link control frame plus its type. For example, “Basic Link Service-ABTS”.

Marker

Bookmark name of the item. This is an editable field shows marker name (if any) for an item.

Markers Count

The “Markers count” value for each frame.

Packet Length

The actual length of the packet.

  • The frame length is expressed in bytes.

  • If the item is not a frame, it is 0.

Pending Commands

The number of commands waiting to complete the exchange. This specifies the number of pending exchanges.

It is an application of the first and last frame of each exchange. For other frames of the exchange, it is null (0).

Port

The port label of the analyzer (the physical port number).

Preset Status

The preset status in training sequence frames. This is a decoded string for an Ethernet training sequence preset response. The decoded value is “Updated” or “Not Updated”.

Protocol Type

Ethernet or Fibre channel. This is “Ethernet” for Ethernet items and “FC” for FC items.

Response Time

Time between the command and response in an exchange.

  • This specifies the response time of an exchange in nanoseconds.

  • It is applicable for first frame of each exchange.; it is null (0) for other frames of the exchange.

Run Date

The Date the trace was captured. It specifies Date/Time that an item was captured.

Start Time

Time stamp of the item. It specifies start time.

Start/Stop

It is applicable only for SCSI Start/Sop Unit command and is a string decoded value for Start/Stop bit. If this bit is 1, decoded value is “START”, otherwise is “STOP”

TCP bits

TCP special bit values such as ACK, RST.

  • This is a decoded string value for the following TCP framebits: RESET, NS, SYNC, FINISH, CWR, ECE, URGENT, ACK, and PUSH.

  • If any of above bits is 1, decoded string contains [name], for example if SYNC and ACK are 1, the decoded value is [SYN], [ACK].

TCP Payload Length

TCP Payload length of the packet if the frame is TCP. The TCP frame payload length is expressed in bytes.

Throughput

The total number of transferred bytes of an exchange divided by the duration of the exchange. In MB/s.

Time Delta

Delta time between current item and previous row. This specifies the start time difference between each item and the previous item.

TLS Function name

The TLS content types or handshake types in the packet, if any. This is a string that includes the decoded content types or handshake types in the order they appear in the packet. The Application Data content type is not shown, and for the Handshake content type, only the handshake types are displayed.

Examples: Change Cipher Spec; Encrypted Extension; Finished

Training sequence explanation

Explanation for training sequence frames. This is a decoded string for training sequence items.

Transport function name

The transport function name of the packet, if any.

This is a string, including a decoded abstract of the item, depending on frame type; it contains decoded string of major field in the frame.
