Chapter 1  Port Correlation Configuration Commands

1.1  Port Correlation Configuration Commands

1.1.1  broadcast-suppression

Syntax

broadcast-suppression ratio

undo broadcast-suppression

View

Ethernet port view, port group view

Parameters

ratio: Maximal ratio of broadcast traffic to the total transmission capability of an Ethernet port, in the range 1 to 100 . The smaller the ratio, the less broadcast traffic is allowed to pass through the interface. The system default is 100.

Description

Use the broadcast-suppression command to configure the broadcast storm suppression ratio for one or multiple ports.

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

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

If you execute this command in Ethernet port view, the configurations take effect only on the current interface. If you execute this command in port-group view, the configurations take effect on all ports in the port group.

Note that when broadcast traffic exceeds the maximum value configured, the system will discard the extra packets so that the broadcast traffic ratio falls below the limit to ensure that the network functions properly.

 

 

Examples

# Allow broadcast traffic equivalent to 20% of the total transmission capability of Ethernet 1/0/1 to pass and suppress the excessive broadcast packets.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] broadcast-suppression 20

# On all ports of the manual port group named group1, allow broadcast traffic equivalent to 20% of the total transmission capability of each port to pass and suppress excessive broadcast packets.

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.
-	Hypen, which is used to connect two numbers or characters. Note that the number to the left of this character need 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 grouyp 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.

1.1.22  reset counters interface

Syntax

reset counters interface [ interface-type [ interface-number ] ]

View

User view

Parameters

interface-type: Port type.

interface-number: Port number.

Description

Use the reset counters interface command to reset statistics for a specified port.

To sample network traffic within a period of time for a port, you need to reset the original port statistics.

l           If neither port type nor port number is specified, all port information will be reset;

l           If only port type is specified, then only information of this particular type of port will be reset.

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

Examples

# Clear the statistics on Ethernet 1/0/1.

<Sysname> reset counters interface ethernet 1/0/1

1.1.23  shutdown

Syntax

shutdown

undo shutdown

View

Ethernet port view

Parameters

None

Description

Use the shutdown command to shut down an Ethernet port.

Use the undo shutdown command to turn on Ethernet port.

In certain circumstances, modification to the port parameters does not immediately take effect, and therefore, you need to shut down the relative port to make the modification work.

Examples

# Shut down Ethernet 1/0/1.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] shutdown

# Bring up Ethernet 1/0/1.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] undo shutdown

1.1.24  speed

Syntax

speed { 10 | 100 | 1000 | auto }

undo speed

View

Ethernet port view

Parameters

10: Specifies the port rate as 10 Mbps.

100: Specifies the port rate as 100 Mbps.

1000: Specifies the port rate as 1,000 Mbps. This keyword is available only in 1000-Mbps Ethernet port view.

auto: Specifies to determine the port rate through auto-negotiation.

Description

Use the speed command to configure the Ethernet port rate.

Use the undo speed command to restore the default.

By default, Ethernet port data rate is automatically negotiated between peer Ethernet ports. For a SFP port that uses a 100-Mbps module, the default data rate is 100 Mbps. For a SFP port that uses a 1000-Mbps module, the default data rate is 1000 Mbps.

Related commands: duplex.

 

 

Examples

# Configure the port rate as 100 Mbps for Ethernet 1/0/1.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] speed 100

1.1.25  virtual-cable-test

Syntax

virtual-cable-test

View

Ethernet port view

Parameters

None

Description

Use the virtual-cable-test command to enable the virtual cable test for an Ethernet port and to display the testing result. The tested items include:

l           Cable status: Could be normal, abnormal, abnormal-open, abnormal-short, and failure;

l           Cable length;

l           Pair Impedance mismatch;

l           Pair skew;

l           Pair swap;

l           Pair polarity;

l           Insertion loss;

l           Return loss;

l           Near-end crosstalk.

By default, virtual cable test is disabled.

Note:

l           When the cable is functioning properly, the cable length in the test result represents the total cable length;

l           When the cable is not functioning properly, the cable length in the test result represents the length from the current port to the failed position.

 

 

Examples

# Enable the virtual cable test for Ethernet 1/0/1.

<Sysname> system-view

[Sysname] interface ethernet 1/0/1

[Sysname-Ethernet1/0/1] virtual-cable-test

Cable status: abnormal(open), 0 metres

Pair Impedance mismatch: no

Pair skew: - ns

Pair swap: -

Pair polarity: -

Insertion loss: - db

Return loss: - db

Near-end crosstalk: - db
