14.1.2 Port Configuration
Fiber Channel - Port Setup
On the
Port
tab, select from the following options to configure your FC port:
Speed:
Selectable test rates via drop-down menu:
1G (1.0625 Gbps)
2G (2.125 Gbps)
4G (4.25 Gbps)
8G (8.50 Gbps)
10G (10.52 Gbps)
16G (14.025 Gbps)
Link Protocol (PSP):
Enables or Disables the PSP.
Enabling the Primitive Sequence Protocol (PSP) allows link management.
Disabling the Primitive Sequence Protocol (PSP) forces the port into an Active state with no link management.
PSP is an Ordered Set transmitted repeatedly which is used to establish and maintain a link.
PSP also when this setting is enabled.
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:
Offline (OLS)
Not Operational (NOS)
Link Reset (LR)
Link Reset Response (LRR)
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 addressing, and there is no question of availability.
Note
: Fibre Channel defines three topologies: 1) Point-to-Point, 2) Arbitrated Loop, and 3) Fabric; however, Point-
to-Point topology is the least complex.
Link Management:
Enable or Disable.
Only available when PSP is enabled.
Initializes the Fibre Channel link and manages various states, including link failure, loss of synchronization, loss of signal,
or protocol violations.
B-to-B (Tx): Buffer to Buffer:
Valid settings are in the range from 1 to 65535.
Number of local port frame buffers are available to receive frames from another port
Determines how many frames can be sent before receiving R_RDY acknowledgements.
“Credits”, or the number of frames, are negotiated between the n_ports and f_ports at the time of login
Both ports on the link exchange values of how many frames they are willing to receive at a time from the other port. This
value becomes the other port's BB_Credit value and remains constant as long as the ports are logged in.
Each port also keeps track of BB_Credit_CNT.
