# packet.link.erf(3)

ERF module

## NAME

packet.link.erf - ERF module

## DESCRIPTION

Decode Extensible Record Format layer Reference: ERF Types Reference Guide, EDM11-01 - Version 21

## CLASSES

### class ERF(baseobj.BaseObj)

```
Extensible record format object
Usage:
    from packet.link.erf import ERF
    x = ERF(pktt)
Object definition:
ERF(
    timestamp = int64,  # The time of arrival, an ERF 64-bit timestamp
    rtype     = int,    # ERF type
    flags     = int,    # ERF flags
    rlen      = int,    # Record length
    lctr      = int,    # Loss counter/color field
    wlen      = int,    # Wire length
    psize     = int,    # Payload data size
)
```

**Methods defined here:** ---------------------

**\_\_init\_\_(self, pktt)** Constructor

Initialize object's private data.

- **pktt:**

  Packet trace object (packet.pktt.Pktt) so this layer has access to the parent layers.

**\_\_str\_\_(self)** String representation of object

The representation depends on the verbose level set by debug\_repr(). If set to 0 the generic object representation is returned. If set to 1 the representation of the object is condensed:\
     'rtype=21 rlen=312 wlen=290 '

If set to 2 the representation of the object also includes the type of payload:\
     'rtype: 21(InfiniBand), rlen: 312, wlen: 290 '

### class ERF\_TS(builtins.int)

```
ERF Time Stamp
```

**Methods defined here:** ---------------------

**\_\_str\_\_(self)** Return str(self).
