ratio: Specifies the maximal ratio of broadcast traffic for an Ethernet interface. It ranges between 1 to 100 and defaults to 100. The smaller the ratio, the less broadcast traffic allowed through the interface.

pps max-pps: Specifies the maximal broadcast packet number per second for an Ethernet interface. It ranges between 1 to 1,488,000 for GigabitEthernet port(s) and 1 to 1,488,0000 for 10GE port(s) in pps, representing packets per second.

Description

Use the broadcast-suppression command to configure broadcast storm suppression ratio.

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

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

The above commands apply to the current port only while executed under Ethernet interface view, or to all ports in a port group while executed under port group view.

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

Example

# Allow 20% of broadcast traffic to pass through the interface GigabitEthernet 1/0/28, that is, configure the broadcast suppression ratio to 80%.

<Sysname> system-view

[Sysname] interface GigabitEthernet 1/0/28

View

Ethernet interface view/port group view

Parameter

ratio: Specifies the maximal ratio of multicast traffic for an Ethernet interface. Ranges between 1 to 100. The smaller the ratio, the less multicast traffic allowed through the interface.

pps max-pps: Specifies the maximal multicast packet number per second for an Ethernet interface, It ranges between 1 to 1,488,000 for GE port(s) and ranges between 1 to 14,880,000 for 10GE port(s) in pps, representing packets per second.

Description

Use the multicast-suppression command to configure multicast storm suppression ratio.

View

System view

Parameter

manual port-group-name: Name of a specified manual port group, a string of 1 to 32 characters.

aggregation agg-id: Number of the specified port aggregation group. The specified port aggregation group must already exist. You can use the display link-aggregation summary command to display brief information of all existing port aggregation groups.

Description

l Use the port-group manual command to enter a specified manual port group view. If the manual port group does not exist, you need to create it first before entering its view.

l Use the port-group aggregation command to enter a port group aggregation view.

l Use the undo port-group manual command to delete a specified manual port group.

By default, no manual port group is configured.

1.1.23 port link-type

Syntax

port link-type { access | hybrid | trunk }

undo port link-type

View

Ethernet interface view/port group view

Parameter

access: Specifies the link type of a port as Access.

hybrid: Specifies the link type of a port as Hybrid.

trunk: Specifies the link type of a port as Trunk.

Description

Use the port link-type command to configure Ethernet port link type.

1.1.24 reset counters interface

Syntax

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

View

User view

Parameter

interface-type: Interface type.

interface-number: Interface number

Description

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

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

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

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

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

Example

# Reset statistics for the interface GigabitEthernet 1/0/1.

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

1.1.25 shutdown

Syntax

shutdown

undo shutdown

View

Ethernet interface view

Parameter

None

Description

Use the shutdown command to shut down an Ethernet interface.

Use the undo shutdown command to turn on Ethernet interface.

By default, Ethernet interface is enabled.

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.

Example

# Shut down the interface GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface GigabitEthernet 1/0/1

[Sysname-GigabitEthernet1/0/1] shutdown

# Turn on the interface GigabitEthernet 1/0/1.

[Sysname-GigabitEthernet1/0/1] undo shutdown

1.1.26 speed

Syntax

speed { 10 | 100 | 1000 | auto }

undo speed

View

Ethernet interface view

Parameter

10: Indicates that the interface rate is 10 Mbps.

100: Indicates that the interface rate is 100 Mbps.

1000: Indicates that the interface rate is 1000 Mbps.

auto: Indicates that the interface rate is automatically negotiated between peer Ethernet interfaces.

Description

Use the speed command to configure Ethernet interface data rate.

Use the undo speed command to restore Ethernet interface data rate.

By default, Ethernet interface data rate is automatically negotiated between peer Ethernet interfaces.

l Combo port only supports speed auto and speed 1000.

l 10GE port cannot support speed command.

Note that he Combo port does not support the speed command.

Example

# Configure data rate for the interface GigabitEthernet 1/0/2 to 100 Mbps.

1.1.27 unicast-suppression

Syntax

unicast-suppression { ratio | pps max-pps }

undo unicast-suppression

View

Ethernet interface view/port group view

Parameter

ratio: Specifies the maximal ratio of unicast traffic for an Ethernet interface. Ranges between 1 to 100. The smaller the ratio, the less unicast traffic allowed through the interface.

pps max-pps: Specifies the maximal unicast packet number per second for an Ethernet interface. It ranges between 1 to 1,488,000 for GigabitEthernet port(s) and 1 to 1,488,0000 for 10GE port(s) in pps, representing packets per second.

Description

Use the unicast-suppression command to configure unicast storm suppression ratio.

Use the undo unicast-suppression command to restore unicast suppression ratio.

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

The above commands apply to the current port only while executed under Ethernet interface view, or to all ports in a port group while executed under port group view.

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

Example

# Allow 20% of unicast traffic to pass through the interface GigabitEthernet 1/0/28, that is, configure the unicast suppression ratio to 80%.

<Sysname> system-view

[Sysname] interface GigabitEthernet 1/0/28

[Sysname-GigabitEthernet1/0/28] unicast-suppression 20

# On all ports of the manual port group “Group1” ( from GigabitEthernet 1/0/1 to GigabitEthernet 1/0/5 ), allow unknown unicast traffic equivalent to 20% of the total transmission capability of each port to pass and suppress excessive unknown unicast packets.

1.1.28 virtual-cable-test

Syntax

virtual-cable-test

View

Ethernet interface view

Parameter

None

Description

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

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 that:

l When the cable is functioning properly, the cable length in the test result represents no meaning;

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 Currently the S5500-SI Series Ethernet Switches support the tested items include: cable status and cable length.

Example

# Enable the virtual cable test for the interface GigabitEthernet 1/0/1.
