broadcast-suppression

Syntax

broadcast-suppression { ratio | pps max-pps | kbps max-kbps }

undo broadcast-suppression

View

Ethernet interface view, port group view

Default Level

2: System level

Parameters

ratio: Sets the broadcast suppression threshold as a percentage of the port transmission capability, in

the range 1 to 100. The smaller the percentage, the less broadcast traffic is allowed to pass through.

pps max-pps: Sets the broadcast suppression threshold in pps to limit the number of broadcast

packets passing through the Ethernet port per second.

 For 100 Mbps port, the value range is 1 to 148810.

 For a Gigabit port, the value range is 1 to 1488100.

 For a 10-Gigabit port, the value range is 1 to 1488100.

kbps max-bps: Sets the broadcast suppression threshold in kbps to limit the number of kilobits of

broadcast traffic passing through the Ethernet port per second.

 For 100 Mbps port, the value range is 1 to 100000.

 For a Gigabit port, the value range is 1 to 1000000.

 For a 10-Gigabit port, the value range is 1 to 10000000.

Description

Use the broadcast-suppression command to set the broadcast suppression threshold on one or

multiple Ethernet interfaces.

Use the undo broadcast-suppression command to restore the default.

By default, Ethernet interfaces do not suppress broadcast traffic.

If you execute this command in Ethernet interface, the configuration takes effect only on the current

interface. 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 suppression threshold, the interface discards broadcast

packets until the broadcast traffic drops below the threshold.

1-2

 If you set different broadcast suppression thresholds in Ethernet interface view or port-group view

multiple times, the one configured last takes effect.

 For a particular type of traffic, configure either storm suppression or storm control, but not both. If

both of them are configured, you may fail to achieve the expected storm control effect.

Examples

# Set the broadcast suppression threshold to 20% on Ethernet interface GigabitEthernet 2/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 2/0/1

[Sysname-GigabitEthernet2/0/1] broadcast-suppression 20

# Set the broadcast suppression threshold to 20% on all ports in manual port group group1.

<Sysname> system-view

[Sysname-port-group-manual-group1] broadcast-suppression 20

Syntax

description text

undo description

View

Ethernet interface view

Default Level

2: System level

Parameters

text: Creates an interface description, a string of 1 to 80 characters. Valid characters and symbols

include English letters (A to Z, a to z), digits (1 to 9), special English characters, spaces, and other

Unicode characters and symbols.

 Each Unicode character takes the space of two regular characters.

 To use a type of Unicode characters or symbols in an interface description, install the specific

input method editor and log in to the device through remote login software that supports this

character type.

 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.

1-3

Description

Use the description command to change the description of the current interface.

Use the undo description command to restore the default.

The default description of an interface is the interface name plus Interface, GigabitEthernet2/0/1

Interface for example.

Related commands: display interface.

Examples

# Change the description of interface GigabitEthernet 2/0/1 to lanswitch-interface.

<Sysname> system-view

[Sysname] interface gigabitEthernet 2/0/1

regular-expression ]

display interface [ interface-type ] brief down [ | { begin | exclude | include } regular-expression ]

View

Any view

Default Level

1: Monitor level

Parameters

interface-type: Specifies an interface type.

interface-number: Specifies an interface number.

down: Displays information about interfaces in DOWN state and the relevant causes.

|: Filters command output by specifying a regular expression. For more information about regular

expressions, see CLI Configuration in the Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow.

exclude: Displays the lines that do not match the specified regular expression.

include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, which is a case sensitive string of 1 to 256

characters.

Description

Use the display brief interface command to display brief interface information.

 If neither interface type nor interface number is specified, this command displays information

about all interfaces.

 If only interface type is specified, this command displays information about interfaces of the

specified type.

 If both interface type and interface number are specified, this command displays information about

the specified interface.

# Display brief information about all interfaces.

Table 1-1 display interface brief command output description

Field Description

The brief information of

interface(s) under route

mode:

The command displays brief information about Layer 3 interfaces

Link: ADM -

administratively down;

Stby - standby

AMD

indicates that the interface has been shut down by the network

administrator. To recover its physical layer state, perform the

undo shutdown

command.

Stby

indicates that the current interface is a standby interface.

Protocol: (s) - spoofing

If the network layer protocol state of an interface is shown as UP, but its link is an

on-demand link or not present at all, its protocol attribute includes the spoofing

flag (an

s

in parentheses). This attribute is typical of interface Null 0 and the

loopback interfaces.
