Chapter 1  Ethernet Interface Configuration Commands

1.1  Ethernet Interface Configuration Commands

1.1.1  broadcast-suppression

Syntax

broadcast-suppression { ratio | pps max-pps }

undo broadcast-suppression

View

Ethernet interface view, port group view

Default Level

2: System level

Parameters

ratio: Specifies a percentage of the total interface bandwidth for broadcasts on the interface, in the range 1 to 100. The smaller the ratio is, the less the broadcast traffic is allowed through the interface.

pps max-pps:  Specifies the maximum number of broadcast packets allowed to pass through the interface every second, in the range 1 to 1488100 (in pps, packets per second).

Description

Use the broadcast-suppression command to configure broadcast suppression by setting a broadcast traffic threshold.

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

By default, all broadcast traffic is allowed to go through an Ethernet interface, that is, broadcast traffic is not suppressed.

Configured in Ethernet interface view, the command takes effect only on the current interface; configured in port group view, the command takes effect on all interfaces in the port group.

l           With broadcast suppression enabled, the switch discards all broadcasts that cross the predefined broadcast threshold to ensure the operation of network services.

l           The broadcast suppression setting you configured will overwrite the previous broadcast suppression setting, if any.

l           With multicast suppression enabled, broadcast suppression is enabled automatically. However, with broadcast suppression enabled, multicast suppression can not be enabled.

l           You cannot enable broadcast suppression and multicast suppression on a board at the same time. If you have enabled broadcast suppression on some ports of a board, you cannot enable multicast suppression on the other ports, and vice versa.

Examples

# Set the broadcast threshold to 20 for Ethernet 1/1/1.

<Sysname> system-view

[Sysname] interface ethernet 1/1/1

[Sysname-Ethernet1/1/1] broadcast-suppression 20

# Set the broadcast threshold to 20 for all the interfaces in port group 1.

<Sysname> system-view

[Sysname] port-group manual group1

[Sysname-port-group manual group1] group-member ethernet 2/1/1

[Sysname-port-group manual group1] group-member ethernet 2/1/2

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

1.1.2  debugging ethernet packet

Syntax

debugging ethernet packet [ interface interface-type interface-number ]

undo debugging ethernet packet

View

User view

Default Level

1: Monitor level

Parameters

interface interface-type interface-number: Specifies an interface by its type and number.

Description

Use the debugging ethernet packet command to enable Ethernet packet debugging for a specified interface or globally if no interface is specified.

Use the undo debugging ethernet packet command to disable Ethernet packet debugging.

By default, Ethernet packet debugging is disabled.

Examples

# Enable Ethernet packet debugging.

<Sysname> debugging ethernet packet

1.1.3  description

Syntax

description text

undo description

View

Ethernet interface view, POS interface view

Default Level

2: System level

Parameters

text: Interface description information, a string of 1 to 80 characters.

Description

Use the description command to set the description of a specific interface.

Use the undo description command to restore the default.

By default, the description of an interface is interface index + interface.

Examples

# Set the description to lanswitch-interface for Ethernet 1//1/1.

<Sysname> system-view

[Sysname] interface ethernet 1/1/1

[Sysname-Ethernet1/1/1] description lanswitch-interface

1.1.4  display brief interface

Syntax

display brief interface [ interface-type [ interface-number ] ] [ | { begin | include | exclude } text ]

View

Any view

Default Level

1: Monitor level

Parameters

interface-type: Interface type.

interface-number: Interface number.

|: Uses a regular expression to filter output information.

begin: Displays the configuration information from the line that contains the string specified by the text argument.

include: Displays only the lines that contain the string specified by the text argument.

exclude: Displays all the lines that do not contain the string specified by the text argument.

text: Regular expression, a string of 1 to 256 characters. This argument is case-sensitive and allows spaces.

Table 1-1 Special characters used in regular expressions

Character	Meaning	Notes on Use
^	Boundary matcher for the beginning of a line. This character specifies a string with which a line begins.	The regular expression “^user” matches lines that begin with the string “user”. Lines that don t begin with the string “user”, for example, “Auser”, are not matched.
$	Boundary matcher for the end of a line. This character specifies a string with which a line ends.	The regular expression “user$” matches lines that end with the string “user”. Lines that do not end with the string, for example, “userA”, are not matched.
.	Full stop, used as the wildcard character, which matches any single character, including space.	None
*	Star, which matches the occurrences of the character to the left for zero or multiple times	zo* matches z and zoo.
+	Plus, which  matches one or multiple occurrences of the character to the left	zo+ matches zo and zoo, but not z.
-	Hyphen, which is used to connect two numbers or characters. Note that the number to the left of this character needs to be larger than the one to the right. When used in a “[“ and “]” pair, it represents a range.	”1-9” represent a range from 1 to 9 (“1” and “9” included), and a-h represent a range from “a” to “h” (“a” and “h” included).
[ ]	Specifies a range.	[1-36A] matches a character, which can be a number in the range 1 to 36 or character A.
( )	Specifies a group of characters. Usually used with “+” and “*”.	(123A) specifies the string “123A”. 408(12)+ matchers “40812” or “408121212” (but not “408”). That is, “12” can appear for multiple times.

 

Description

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

l           If neither interface type nor interface number is specified, all interface information will be displayed;

l           If only interface type is specified, then only information of this particular type of interface will be displayed.

l           If both interface type and interface number are specified, then only information of the specified interface will be displayed.

1.1.24  multicast-suppression

Syntax

multicast-suppression { ratio | pps max-pps }

undo multicast-suppression

View

Ethernet interface view, port group view

Default Level

2: System level

Parameters

ratio: Specifies a percentage of the total interface bandwidth for multicasts on the interface, in the range 1 to 100. The smaller the ratio is, the less the multicast traffic is allowed through the interface.

pps max-pps:  Specifies the maximum number of multicast packets allowed to pass through the interface every second, in the range 1 to 1488100 (in pps, packets per second).

Description

Use the multicast-suppression command to configure multicast suppression by setting a multicast traffic threshold.

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

By default, all multicast traffic is allowed to go through an Ethernet interface, that is, multicast traffic is not suppressed.

Configured in Ethernet interface view, this command takes effect only on the current interface; configured in port group view, this command takes effect on all interfaces in the port group.

Note that:

l           With multicast suppression enabled, the switch discards all multicast packets that cross the predefined multicast threshold to ensure the operation of network services.

l           The multicast suppression setting you configured will overwrite the previous multicast suppression setting, if any.

l           You cannot enable broadcast suppression and multicast suppression on a board at the same time. If you have enabled broadcast suppression on some ports of a board, you cannot enable multicast suppression on the other ports, and vice versa.

l           With multicast suppression enabled, broadcast suppression is enabled automatically. However, with broadcast suppression enabled, multicast suppression cannot be enabled.

l           Multicast suppression does not differentiate unknown multicasts from known multicasts.

Examples

# Set the multicast threshold to 20 for Ethernet 1/1/1.

<Sysname> system-view

[Sysname] interface ethernet 1/1/1

[Sysname-Ethernet1/1/1] multicast-suppression 20
