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 force a 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. (Avoid using 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.
