broadcast-suppression { ratio | pps max-pps }
undo broadcast-suppression
View
Ethernet port view, port group view, OLT port view
Default Level
2: System level
Parameters
ratio: Maximum percentage of broadcast traffic to the total transmission capability of a port. The smaller the ratio, the less broadcast traffic is allowed to pass through the interface. This argument ranges from 1 to 100. The system default is 100.
pps max-pps: Specifies the maximum number of broadcast packets that can be forwarded on a port, in the range 1 to 1488100 (in pps, representing packets per second). Note that:
l When a suppression granularity larger than 1 is specified on the device, the value of the pps keyword should be no smaller than and an integral multiple of the granularity. The broadcast suppression threshold value configured through this keyword on a port may not be the one that actually takes effect. To display the actual broadcast suppression threshold value on a port, you can use the display interface command.
l When no suppression granularity is specified or the suppression granularity is set to 1, the value of the pps keyword should be no smaller than 1, and the broadcast suppression threshold value is the one that actually takes effect on the port.
Description
Use the broadcast-suppression command to set a broadcast traffic threshold on one or multiple Ethernet ports or an OLT port.
Use the undo broadcast-suppression command to restore the default.
By default, broadcast traffic is not suppressed.
If you execute this command in Ethernet port/OLT port view, the configuration takes effect only on the current port. If you execute this command in port-group view, the configuration takes effect on all the ports in the port group.
When broadcast traffic exceeds the broadcast traffic threshold, the system begins to discard broadcast packets until the broadcast traffic drops below the threshold to ensure operation of network services.
Note that, for a 1000 Mbps port, if you have configured its rate as 100 Mbps or it has negotiated its rate to 100 Mbps, after you use the broadcast suppression command to configure the broadcast suppression ratio on the port, the ratio is the maximum amount of allowed broadcast traffic to 100 Mbps, the total transmission capacity of the port.
If you set different suppression ratios in Ethernet port view or port-group view for multiple times, the latest configuration takes effect.

Parameters
Parameters
text: Description of a port, a string of 1 to 80 characters. Currently, the device supports the following types of characters or symbols: standard English characters (numbers and case-sensitive letters), special English characters, spaces, and other characters or symbols that conform to the Unicode standard.
l A port description can be the mixture of English characters and other Unicode characters. The mixed description cannot exceed the specified length.
l To use a type of Unicode characters or symbols in a port description, you need to install the corresponding Input Method Editor (IME) and log in to the device through remote login software that supports this character type.
l Each Unicode character or symbol (non-English characters) takes the space of two regular characters. When the length of a description string reaches or exceeds the maximum line width on the terminal software, the software starts a new line, possibly breaking a Unicode character into two. As a result, garbled characters may be displayed at the end of a line.
Description
Use the description command to set the description string of the current interface.
Use the undo description command to restore the default.
By default, the description of an interface is the interface name followed by the “interface” string, GigabitEthernet 1/1/1 Interface for example.
Related commands: display interface.
Examples
# Configure the description string of interface GigabitEthernet 1/1/1 as lanswitch-interface.

View
Ethernet port view, port group view, OLT port view
Default Level
2: System level
Parameters
ratio: Maximum percentage of multicast traffic to the total transmission capability of a port, in the range 1 to 100. The smaller the ratio is, the less multicast traffic is allowed to pass through the interface.
pps max-pps: Specifies the maximum number of multicast packets allowed on a port per second. The max-pps argument ranges from 1 to 1488100 in pps, representing packets per second.
Note that:
l When a suppression granularity larger than 1 is specified on the device, the value of the pps keyword should be no smaller than and an integral multiple of the granularity. The multicast suppression threshold value configured through this keyword on a port may not be the one that actually takes effect. To display the actual multicast suppression threshold value on a port, you can use the display interface command.
l When no suppression granularity is specified or the suppression granularity is set to 1, the value of the pps keyword should be no smaller than 1, and the multicast suppression threshold value is the one that actually takes effect on the port.
Description
Use the multicast-suppression command to configure multicast storm suppression ratio on a port.
Use the undo multicast-suppression command to restore the default multicast suppression ratio.
By default, multicast traffic is not suppressed.
If you execute this command in Ethernet port/OLT port view, the configurations take effect only on the current port. If you execute this command in port-group view, the configurations take effect on all ports in the port group.
When multicast traffic exceeds the maximum value configured, the system will discard the extra packets so that the multicast traffic ratio can drop below the limit to ensure that the network functions properly.
Note that, for a 1000 Mbps port, if you have configured its rate as 100 Mbps or it has negotiated its rate to 100 Mbps, after you use the multicast suppression command to configure the multicast suppression ratio on the port, the ratio is the maximum amount of allowed multicast traffic to 100 Mbps, the total transmission capacity of the port.
If you set different suppression ratios in Ethernet port view or port-group view for multiple times, the latest configuration takes effect.

Description
Use the shutdown command to shut down a port.
Use the undo shutdown command to bring up a port.
By default, a port is in the up state.
In certain circumstances, modification to the interface parameters does not immediately take effect, and therefore, you need to shut down the relative interface to make the modification work.
Note that in case of a double Combo port, only one interface (either the optical port or the electrical port) is active at a time. That is, once the optical port is active (after you execute the undo shutdown command), the electrical port will be inactive automatically, and vice versa.

Parameters
10: Specifies the interface rate as 10 Mbps. The optical interface of a Combo port does not support the 10 keyword.
100: Specifies the interface rate as 100 Mbps. The optical interface of a Combo port does not support the 100 keyword.

Parameters
10: Specifies the interface auto-negotiation rate as 10 Mbps.
100: Specifies the interface auto-negotiation rate as 100 Mbps.
1000: Specifies the interface auto-negotiation rate as 1000 Mbps.
Description
Use the speed auto command to configure the auto-negotiation rate range of the current Ethernet port.
Use the undo speed command to restore the default.
The default value of the command varies with your device models.
If you repeatedly use the speed command and the speed auto command to configure the rate of an interface, only the latest configuration takes effect. For example, if you configure speed 100 after configuring speed auto 100 1000 on an interface, the rate is 100 Mbps by force, with no negotiation performed between the interface and the peer end; if you configure speed auto 100 1000 after configuring speed 100 on the interface, the rate through negotiation can be either 100 Mbps or 1000 Mbps only.
Note that:
l If the auto negotiation rate range specified on the local port and that on the peer do not overlap, for example, 10 Mbps and 100 Mbps are specified on one end while 1000 Mbps is specified on the other, the auto negotiation of interface rate will fail.
l If the auto negotiation rate range specified on the local port and that on the peer overlap, for example, 10 Mbps and 100 Mbps are specified on one end while 100 Mbps and 1000 Mbps are specified on the other, the result of the interface rate auto negotiation is the overlapped part, that is, 100 Mbps in the example.
l If the auto negotiation rate range specified on the local port and that on the peer are the same, for example, 100 Mbps and 1000 Mbps are specified on both ends, the result of the interface rate auto negotiation is the larger value, that is, 1000 Mbps in the example.
This function is available for auto-negotiation-capable Gigabit Ethernet electrical ports only.

Parameters
uni-number: Number of an UNI on the ONU, in the range 1 to number of current ONU UNIs. The number of UNIs can be up to 80.
Description
Use the uni virtual-cable-test command to test the cable connected to the specified UNI port of the ONU once and to display the testing result.
Note that:
l When the cable is functioning properly, the OLT does not display the length of the cable connected to the specified UNI port of the ONU under test in the test result; instead, the OLT displays – metres for the corresponding field.
l When the cable is not functioning properly, the cable length in the test result represents the length from the current interface to the failed position.
l This operation will re-enable an up UNI port link.
l The test result is for your information only. The maximum error in the tested cable length is 10 m. A hyphen “-” indicates that the corresponding test item is not supported.
l Support for the uni virtual-cable-test command depends on your ONU model.
Examples
# Use the uni virtual-cable-test command to test the cable connected to UNI 1 of the ONU specified by ONU 1/0/1:1 on the OLT once and to display the testing result.

Parameters
onu-number1: ONU port number, in the range 1 to 64.
to onu-number2: Specifies an ONU port range. onu-number2 is an ONU port number, in the range 1 to 64.
&<1-10>: Indicates that you can specify up to 10 ONU port numbers/port ranges.
Description
Use the using onu command to create virtual ONU port(s) for the current OLT port.
Use the undo using onu command to remove the specified ONU port(s) under the current OLT port.
By default, no ONU port is created for any OLT port when the device is started up.
To use the interface command to enter ONU port view, use the using onu command to create the corresponding ONU port first.
