3.2.1.2.10 rate-suppression
Command: rate-suppression {dlf | broadcast | multicast}
no rate-suppression {dlf | broadcast | multicast}
Function: Sets the traffic limit for broadcasts, multicasts and unknown destination
unicasts on all ports in the switch; the “no rate-suppression” command disables this
traffic throttle function on all ports in the switch, i.e., enables broadcasts, multicasts and
unknown destination unicasts to pass through the switch at line speed.
Parameters: use dlf to limit unicast traffic for unknown destination; multicast to limit
multicast traffic; broadcast to limit broadcast traffic. stands for the number of
packets allowed to pass through per second for non-10Gb ports. For 10 Gb ports, the
number of packets allowed to pass through multiplies 1,040. The valid range for both port
types is 1 to 262,143.
Command mode:
Interface Mode
Default: no limit is set by default. So, broadcasts, multicasts and unknown destination
unicasts are allowed to pass at line speed.
Usage Guide: 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 10Gb ports. However, the same setting for non-10Gb ports means to allow 3
broadcast packets per second and discard the rest.
Example: Setting ports 8-10 (1000Mbps) allow 3 broadcast packets per second.

3.2.1.2.11 show interface status
Command：show interface status[{ethernet | vlan |
port-channel | }]
Function： Show information of specific port on the switch
Parameter： is the port number of the Ethernet, < vlan-id > is the
VLAN interface number, is the number of the aggregation
interface, is the name of the interface such as port-channel1.
Command Mode：
Admin Mode
Default： Information not displayed by default
Usage Guide： As for Ethernet port, this command will show port speed rate, duplex
mode, flow control switch state, broadcast storm restrain of the port and the statistic state
