Table 8: show packet memory Field Descriptions
Description
Field
Data structure that defines and controls an aggregation
of data structures, collectively known as a packet.
Includes information about every packet in the
system.
Packet headers
Data structure that describes a particle and may be
chained to other particles in a linked list. Includes
information about the actual data of the packet and
other particle headers in this packet if present in this
packet.
Particle Pools
Duplicate particle header that points to a previously
allocated particle. Differs from a particle header in
that a particle clone shares the particle with another
particle header.
Particle clone
Scratch pad shared among the features in the packet
path, listing hangs of the packet header.
