Chapter 3 General Management of the Switch 3-103
Note – The integrated switches on the Sun Fire B1600 blade system chassis are each
composed of two switch chips linked together. It is only possible to enable flow
control between two ports that are on the same switch chip. The ports NETP0,
NETP1, NETP4, NETP5, and SNP8 through SNP15 are on one switch chip. The ports
NETP2, NETP3, NETP6, NETP7, and SNP0 through SNP7 are on the other.(If you
look at the rear panel of the SSC, all the ports on the right are on one chip, and all
the ports on the left are on the other.)
■Speed/Duplex23 – The port speed and duplex mode. When auto-negotiation is
disabled, you can manually configure the port speed and duplex mode.
Note – When auto-negotiation is disabled, you can only set the up-link ports to
10 Mbit/sec or 100 Mbit/sec. To forcea port to operate at 1 Gbit/sec full duplex,
enable auto-negotiation, and set the port capabilities to “1000full” only.
■Flow Control23 – When auto-negotiation is disabled, you need to enable or
disable flow control. (Avoidusing flow control on a port connected to a hub
unless it is actually required to solve a problem. Otherwise back pressure
jamming signals may degrade overall performance for the segment connected to
the hub.)
■Broadcast storm suppression – The state of broadcast storm control on the
interface. For more information on broadcast storm control or information on
setting the broadcast threshold level, refer to “Broadcast Storm Control
(Global Setting)” on page 3-67.
