`p4e_commands` module

This module contains the L47 port packet engine classes.

Port (L47) Packet Engine Commands

class P4E_ALLOCATE[source]

Bases: object

Simple mode only: Allocate a number of PEs to this port.

class GetDataAttr[source]

Bases: ResponseBodyStruct

pe_count_alloc: byte, the total number of PEs to allocate to this port - including the PEs already allocated to the port.

class SetDataAttr[source]

Bases: RequestBodyStruct

pe_count_alloc: byte, the total number of PEs to allocate to this port - including the PEs already allocated to the port.

get()[source]

Get the number of PEs allocated to this port.

Returns:: the total number of PEs to allocate to this port - including the PEs already allocated to the port.
Return type:: P4E_ALLOCATE.GetDataAttr

set(pe_count_alloc)[source]

Allocate a number of PEs to this port.

Parameters:: pe_count_alloc (int) – the total number of PEs to allocate to this port - including the PEs already allocated to the port.

class P4E_ALLOCATION_INFO[source]

Bases: object

Display information about which PEs that are available for allocation/assignment and which are currently allocated/assigned to this port.

class GetDataAttr[source]

Bases: ResponseBodyStruct

allocated: eight hex bytes (64-bit) mask of PEs assigned to this port

available: eight hex bytes (64-bit) mask of available PEs

get()[source]

Get PEs allocation information.

Returns:: PEs allocation information
Return type:: P4E_ALLOCATION_INFO.GetDataAttr

class P4E_ASSIGN[source]

Bases: object

Advanced mode only: Assign previously reserved PEs to a port.

class GetDataAttr[source]

Bases: ResponseBodyStruct

mask: eight hex bytes, a bitmask specifying which PEs should be assigned to this port

class SetDataAttr[source]

Bases: RequestBodyStruct

mask: eight hex bytes, a bitmask specifying which PEs should be assigned to this port

get()[source]

Get the assigned PEs on the port.

Returns:: previously reserved PEs
Return type:: P4E_ASSIGN.GetDataAttr

set(mask)[source]

Assign the previously reserved PEs to the port.

Parameters:: mask (str) – a bitmask specifying which PEs should be assigned to this port

class P4E_AVAILABLE[source]

Bases: object

Simple mode only: Report the number of PEs available for allocation.

class GetDataAttr[source]

Bases: ResponseBodyStruct

available_pe_count: byte, total number of PEs that can be allocated to the port - including the PEs already allocated to the port.

get()[source]

Get the number of PEs available for allocation.

Returns:: the number of PEs available for allocation.
Return type:: P4E_AVAILABLE.GetDataAttr
