Description
When the flow control of the switch and the terminal equipment are all
enabled, if some port congestion of the switch occurs, the port will send the
pause frame to the terminal equipment that will be suspended to send data
after receiving the pause frame. Meanwhile, when one port of the switch
receives a pause frame, the port also will be paused to send data.
Note
Enable the flow control to avoid the data packet loss caused by the
inconsistency of the sending and receiving rate. Yet that will also affect the
communication rate of the data source port and other facilities. Please be
careful with this function when linking the network port.
State
Enable/Disable the forwarding function of the selected port.
Enable/Disable the broadcasting storm control function of the selected port. By
default, the storm control is disabled.
Storm Control
Broadcast storm means that the broadcasting frame quantities are soaring up
due to the continuous transmissions, which brings negative effect on the
communication, degrades the system performance and even results in
breakdown of the network.
While enabling the storm control, the switch will discard the excessive
broadcasting messages as the broadcast traffic on the port exceeds the limited
value (2000pps), thus reducing the proportion of the broadcast traffic to the
limited range.
Enable/Disable the address learning function of the selected port.
Address Learning
While enabling the address learning, if no corresponding MAC address in the
MAC address table as the switch receives the data package, it will broadcast
this package to all ports. The switch will record the corresponding MAC port to
the MAC table when the destination host returns some information from one
port.
The MAC address table keeps the system port corresponding to the MAC address of the host linking with that port.
