The sample output below shows that the serial number of the cards zero and one:
# pcie8120-serialno
PCIE-8120#0: 6010687046XX
PCIE-8120#1: 601068703YXX
D.4 Switches Flow Control
By default, the flow control between all the switch ports connected to the DSPs on PCIE-8120
cards are not enabled when PCIE-8120 card is initialized using
pcie8120_init
command.
Due to errata of the switch chip used on PCIE-8120 cards, the flow control cannot be set on all
the ports individually, but it can be set on certain pairs of ports as given below:
(0, 10), (1, 11), (2, 12), (3, 13), (4, 14), (5, 15), (6, 16).
BCM5396 switch chips has 17 ports. Out of 17 ports, 16 ports (port #0 through #15) are
connected on PCIE8120 to either DSPs or front panel RJ45 connectors or to host interface.
port#16 is a special purpose port and is not connected on PCIE8120.
Flow control on Ports 7, 8 and 9 can be set individually.
Flow control on port 11, 12 and 15 connected to DSPs is not enabled by default, due to the
above errata.
The following commands would enable flow control for ports 1 and 11, 2 and 12 and 5 and 15.
For example,
# octmezz --dev=msw0 -w 0x00 0x61 0xbb
msw0: PG:REG 0x0:0x61 -> 0x00bb
# octmezz --dev=msw0 -w 0x00 0x62 0xbb
msw0: PG:REG 0x0:0x62 -> 0x00bb
# octmezz --dev=msw0 -w 0x00 0x65 0xbb
msw0: PG:REG 0x0:0x65 -> 0x00bb
