Link Protocol: Enables or Disables the PSP.
PSP is an Ordered Set transmitted repeatedly which is used to establish and maintain a link.
l
Enabling the Primitive Sequence Protocol (PSP) allows link management
l
Disabling the Primitive Sequence Protocol (PSP) forces the port into an Active state with no
link management
l
When a Primitive Sequence is received and recognized, a corresponding Primitive Sequence
or Idle is transmitted in response. Recognition of a Primitive Sequence requires consecutive
detection of 3 instances of the same Ordered Set. The Primitive Sequences supported by the
standard are:
l
Offline (OLS)
l
Not Operational (NOS)
l
Link Reset (LR)
l
Link Reset Response (LRR)
l
Topology: Point-to-Point (P-to-P) mode is supported.
In Point-to-Point mode, only two ports are used, connected by a fiber optic link. The transmitter of
each port is connected directly to the receiver of the opposite port. There is no ambiguity in address-
ing, and there is no question of availability.
: Fibre Channel defines three topologies: 1) Point-to-Point, 2) Arbitrated Loop, and 3) Fabric;
however, Point-to-Point topology is the least complex.
