Flow control is a ethernet mechanism to indicate a hosts is overwhelmed by incoming traffic. In such a situation, the host can send PAUSE frames to the otherside of the link. When such a PAUSE frame is received, the transmission of the send will be stopped for a specified amount of time. By default, we disable this on our ByteBlower switch en ByteBlower interfaces, because this influences the test and test results.
Enable flow control on the ByteBlower switch
Flow control can be enabled on the ByteBlower switches of the SMC brand.
In attachment, you can find a configfile that will enable flowcontrol on port 1-12.
To install this configfile, follow these instructions:
Connect your switch
Then you should place the attached config file on a tftp server in your network.
Install the configuration file
With these commands, you can then load the config file on the switch:
copy tftp startup-config TFTP server IP address : <tftp_ip> Source configuration file name: smc.24.flowcontrol.conf Startup configuration file name: [startup1.cfg] (extra check) show startup-config (reboot switch) reload
Now you have flow control on port 1-12, and no flow control on port 13-24.
