Description
Display the speed and duplex of all port. There are three speeds
10Mbps, 100Mbps and 1000Mbps supported for TP media, and the
duplex supported is half duplex and full duplex. If the media is 1Gbps
fiber, it is 1000Mbps supported only. The status of speed/duplex
mode is determined by 1) the negotiation of both local port and link
partner in Auto Speed mode or 2) user setting in Force mode. The
local port has to be preset its capability.
Default: None, depends on the negotiation result.
Show each port's flow control status.
There are two types of flow control in Ethernet, Backpressure for
half-duplex operation and Pause flow control (IEEE802.3x) for
full-duplex operation. The switch supports both of them.
Default: Disable
For 10/100M ports, there is no side effect on this setting.
For Gigabit ports, setting of Wait-State will remove the issue with
ignored pause frames but resolve in the minimum interframe gap
being at least 14 bytes instead of the usual 12 bytes. This applies for
uncongested traffic as well. The larger interframe gap will result in
throughput rates less than 100%. For example, a stream of 64-byte
frames and a stream of 1518-byte frames, their maximum throughput
is 97.7% and 99.9% respectively.
