Table 2 contains a summary of the specifications, standards, and protocols that
apply to the switch.
Chapter 1. The IBM Flex System FC3171 8 Gb SAN Switch
The pass-thru module presents one or more compute nodes per port to the fabric.
The pass-thru module expands the fabric, but, unlike a full fabric switch, it does
not count against the fabric domain.
Note: A node port is also known as an N_port.
The switch supports the following error-detection methods:
— Cyclic redundancy check (CRC)
— 8-byte and 10-byte conversion
— Parity
— Long frame and short frame
— D_ID mismatch
— S_ID mismatch
The switch supports the following frame bundling methods:
— No frame bundling. Frames are intermixed from different sources at will.
— Soft lockdown. The switch waits for the sequence to be completed or a gap
in the frame traffic to occur before it services requests from a different port.
A FAN, as described in FC-FLA, is sent out by the fabric after an initialization
event (usually a loop initialization port) to each attached NL_Port. The purpose
of the FAN is to inform the attached NL_Ports of the fabric node name, port
name, and fabric address.
