DCS-3950 series Ethernet switch manual
multicasted flow. brmcdlf is for boradcasted or multicasted or DLF flow. all is for all types
of flow.
Command mode: Interface Mode
Default: Frame is delivered at line speed by default.
Usage Guide: With this command, bandwidth can be controlled for specific flow types. All
ports in the switch belong to a same broadcast domain if no VLAN has been set. The
switch will send the abovementioned three traffics to all ports in the broadcast domain,
which may result in broadcast storm and so may greatly degrade the switch performance.
Enabling Broadcast Storm Control can better protect the switch from broadcast storm.
Note the difference of this command in 10Gb ports and other ports. If the allowed traffic is
set to 3, this means allow 3,120 packets per second and discard the rest for 10 GB ports.
However, the same setting for non-10Gb ports means to allow 3 broadcast packets per
second and discard the rest.
Example: Llimit the number of broadcasting packet that can be received by the switch to
be 1000kbit per second.

7.2.1.2.3 speed-duplex
Command: speed-duplex {auto|force10-half|force10-full|force100-half|force100-full |
force100-fx |{{force1g-half | force1g-full} [nonegotiate [master|slave]] }}
Function: Configure the speed and duplex mode of the port.
Parameters: auto is for auto negotiation. force10-half is for forced speed of 10Mbit/s,
and half duplex mode. force10-full is for forced speed of 10Mbit/s and full duplex mode.
force100-half is for forced speed of 100Mbit/s and half duplex mode. force100-full is for
forced 100Mbit/s. force100-fx is for forced 100Mbit/s fiber mode. force1g-half is for forced
1000Mbit/s and half duplex mode. force1g-full is for forced 1000Mbit/s and full duplex
mode.
Command mode: Interface Mode.
Default: Speed and duplex auto negotiation is enabled by default.
Usage Guide: When configuring the speed and duplex of a port, the speed and duplex
must keep compatible with the remote connection pear. If the remote pear is configured as
auto negotiation, the local pear should be configured the same. If the remote one is
configured in forced mode, the local should be too.
Example: Connect the port 1 of Switch1 with the port 1 of Switch2, and configure them as
forced 100Mbit/s and half duplex mode.
Switch1(Config)#interface ethernet 0/0/1
Switch1(Config-Ethernet1-0/0/1)#speed-duplex force100-half
Switch2(Config)#interface ethernet 0/0/1
Switch2(Config-Ethernet0/0/1)#speed-duplex force100-half
