Parameters

ratio: Sets the broadcast suppression threshold as a percentage of the interface bandwidth. The value range for this argument is 0 to 100. A smaller value means that less broadcast traffic is allowed to pass through.

pps max-pps: Specifies the maximum number of broadcast packets that the interface can forward per second. The value range for the max-pps argument (in pps) is 0 to 1.4881 × the interface bandwidth.

kbps max-kbps: Specifies the maximum number of kilobits of broadcast traffic that the Ethernet interface can forward per second. The value range for this argument (in kbps) is 0 to the interface bandwidth.

Usage guidelines

The broadcast storm suppression features limits the size of broadcast traffic to a threshold on an interface. When the broadcast traffic on the interface exceeds this threshold, the system drops packets until the traffic drops below this threshold.

Both the storm-constrain command and the broadcast-suppression command can suppress broadcast storms on a port. The broadcast-suppression command uses the chip to physically suppress broadcast traffic. It has less influence on the device performance than the storm-constrain command, which uses software to suppress broadcast traffic.

For the traffic suppression result to be determined, do not configure both the storm-constrain broadcast command and the broadcast-suppression command on an interface.

The configured suppression threshold value in pps or kbps might be converted into a multiple of a step supported by the chip. As a result, the effective suppression threshold might be different from the configured one. To determine the suppression threshold that takes effect, see the prompts on the device.

Examples

# Set the broadcast suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] broadcast-suppression kbps 10000

The actual value is 10048 on port GigabitEthernet1/0/1 currently.

The output shows that the value that takes effect is 10048 kbps (157 times of 64), because the chip only supports step 64.

Parameters

copper: Activates the copper combo port. In this case, use twisted pairs to connect the port.

fiber: Activates the fiber combo port. In this case, use optical fibers to connect the port.

Usage guidelines

A combo interface is a logical interface that physically contains one fiber combo port and one copper combo port on the device panel. The two ports share one forwarding interface. As a result, they cannot work simultaneously. When you activate either port, the other port is automatically disabled. You can select to activate the copper combo port or fiber combo port.

Before using this command, perform the following tasks according to the marks on the device panel:

· Determine the combo interfaces on your device.

· Identify the two physical interfaces that belong to each combo interface.

Examples

# Activate the copper combo port of combo interface GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] combo enable copper

Predefined user roles

network-admin

context-admin

Parameters

half-life: Specifies the amount of time after which a penalty is decreased, in the range of 1 to 120 seconds. The default value is 54 seconds.

reuse: Specifies the reuse threshold in the range of 200 to 20000. The default value is 750. The reuse threshold must be less than the suppression threshold.

suppress: Specifies the suppression threshold in the range of 200 to 20000. The default value is 2000.

max-suppress-time: Specifies the maximum amount of time the interface can be dampened, in the range of 1 to 255 seconds. The default value is 162 seconds (three times the half-life timer).

Usage guidelines

When configuring the dampening command, follow these rules to set the values mentioned above:

· The ceiling is equal to 2 (Max-suppress-time/Decay) × reuse-limits. It is not user configurable.

· The configured suppress limit is lower than or equal to the ceiling.

· The ceiling is lower than or equal to the maximum suppress limit supported.

This command and the link-delay command are mutually exclusive on an interface.

This command does not take effect on the administratively down events. When you execute the shutdown command, the penalty restores to 0, and the interface reports the down event to the higher layer protocols.

Do not enable the dampening function on an interface with spanning tree protocols or Smart Link enabled.

After an interface in down state is dampened, the interface state displayed through the display interface command, MIB, or Web is always down.

Examples

# Enable interface dampening on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] dampening

# Enable interface dampening on GigabitEthernet 1/0/1, and set the following parameters:

With the CRC error packet alarm function enabled, when the number of incoming CRC error packets on an interface in normal state within the specified interval exceeds the upper threshold, the interface generates an upper threshold exceeding alarm and enters the alarm state. When the number of incoming CRC error packets on an interface in the alarm state within the specified interval drops below the lower threshold, the interface generates a recovery alarm and restores to the normal state.

You can configure the CRC error packet alarm parameters in system view and interface view.

· The configuration in system view takes effect on all interfaces of the specified slot. The configuration in interface view takes effect only on the current interface.

· For an interface, the configuration in interface view takes priority, and the configuration in system view is used only when no configuration is made in interface view.

When you execute this command multiple times, the most recent configuration takes effect.

Parameters

high-threshold high-value: Specifies the upper threshold for SDH-B1 error packet alarms, in the range of 1 to 4294967295 packets.

low-threshold low-value: Specifies the lower threshold for SDH-B1 error packet alarms, in the range of 1 to 4294967295 packets.

interval interval: Specifies the statistics collection and comparison interval for SDH-B1 error packets, in the range of 1 to 65535 seconds.

shutdown: Shuts down an interface when the number of incoming SDH-B1 error packets on the interface exceeds the upper threshold. Then, the interface stops forwarding all packets. To recover the interface, execute the undo shutdown command on the interface. If you do not specify this keyword, an upper threshold exceeding alarm is generated and the interface enters the alarm state when the number of incoming SDH-B1 error packets exceeds the upper threshold on the interface.

slot slot-number: Specifies an IRF member device by its member ID.

Usage guidelines

With the SDH-B1 error packet alarm function enabled, when the number of incoming SDH-B1 error packets on an interface in normal state within the specified interval exceeds the upper threshold, the interface generates an upper threshold exceeding alarm and enters the alarm state. When the number of incoming SDH-B1 error packets on an interface in the alarm state within the specified interval drops below the lower threshold, the interface generates a recovery alarm and restores to the normal state.

You can configure the SDH-B1 error packet alarm parameters in system view and interface view.

· The configuration in system view takes effect on all interfaces of the specified slot. The configuration in interface view takes effect only on the current interface.

· For an interface, the configuration in interface view takes priority, and the configuration in system view is used only when no configuration is made in interface view.

For this command to take effect, you must use the snmp-agent trap enable ifmonitor command to enable the SDH-B1 error packet alarm function.

When you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the upper threshold to 65, lower threshold to 25, and statistics collection and comparison interval to 20 seconds for SDH-B1 error packet alarms.

Parameters

hotbackup: Specifies hot backup packets.

relay: Specifies relay packets.

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

vlan vlan-id: Specifies a VLAN by its ID in the range of 2 to 4094. Packets are forwarded in the VLAN. If you do not specify this option, packets are forwarded in VLAN 2. The VLAN ID cannot be the PVID of an inner interface on a peer.

Usage guidelines

On an IRF fabric formed by SecBlade modules, the IRF physical interfaces forward hot backup and relay packets by default. Enable this feature to avoid unstable IRF connections when the IRF physical interface bandwidth is insufficient for hot backup and relay packets between SecBlade modules.

The inner interface is the inner Ethernet interface through which a SecBlade module communicates with the device.

Hot backup packets are exchanged between SecBlade modules to realtime back up the session entries and session-based service (NAT, ALG, and ASPF) entries. Relay packets are packets transparently transmitted between SecBlade modules.

Hot backup and relay packets can be forwarded through the same inner interface or different inner interfaces.

You can execute this command multiple times to specify multiple inner interfaces to forward hot backup and relay packets.

As a best practice, do not enable a spanning tree protocol on an inner interface with this feature enabled and its peer interface. The forwarding of relay, hot backup, and batch backup packets fails during spanning tree topology convergence. For more information about spanning tree protocols, see spanning tree in Layer 2—LAN Switching Configuration Guide.

Parameters

msec: Enables the physical state change suppression interval to be accurate to milliseconds. If you do not specify this keyword, the suppression interval is accurate to seconds.

delay-time: Sets the physical state change suppression interval on the Ethernet interface. A value of 0 means that physical state changes are immediately reported to the CPU and are not suppressed.

· If you do not specify the msec keyword, the value range is 0 to 30 seconds.

· If you specify the msec keyword, the value range is 0 to 10000 milliseconds, and the value must be a multiple of 100.

mode up: Suppresses the link-up events.

mode updown: Suppresses both the link-up and link-down events.

Usage guidelines

You can configure this feature to suppress only link-down events, only link-up events, or both. If an event of the specified type still exists when the suppression interval expires, the system reports the event.

When you configure this feature, follow these guidelines:

· To suppress only link-down events, configure the link-delay [ msec ] delay-time command.

· To suppress only link-up events, configure the link-delay [ msec ] delay-time mode up command.

· To suppress both link-down and link-up events, configure the link-delay [ msec ] delay-time mode updown command.

On an interface, you can configure different suppression intervals for link-up and link-down events. If you configure the link-delay command multiple times for link-up or link-down events, the most recent configuration takes effect.

Do not execute this command on an interface that has spanning tree protocols or Smart Link enabled.

This command and the dampening command are mutually exclusive on an Ethernet interface.

Examples

# Set the link-down event suppression interval to 8 seconds on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] link-delay 8

# Set the link-up event suppression interval to 800 milliseconds on GigabitEthernet 1/0/1.

CAUTION:

After you enable loopback testing on an Ethernet interface, the interface does not forward data traffic.

‌

Use loopback to enable loopback testing on an Ethernet interface.

Use undo loopback to disable loopback testing on an Ethernet interface.

Syntax

Parameters

external: Enables external loopback testing on the Ethernet interface.

internal: Enables internal loopback testing on the Ethernet interface.

Usage guidelines

After you enable loopback testing on an Ethernet interface, the Ethernet interface switches to full duplex mode. After you disable loopback testing, the Ethernet interface restores to its duplex setting.

The shutdown and loopback commands are mutually exclusive.

With loopback testing enabled on an interface on an F1005, F1010, F1000-AK108, F1000-AK109, F1000-AK110, or F1000-AK120 device, the speed of the interface changes to 100 Mbps. The speed restores to the original settings when loopback testing is disabled on the interface.

Examples

# Enable internal loopback testing on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] loopback internal

multicast-suppression

Use multicast-suppression to enable multicast storm suppression and set the multicast storm suppression threshold.

Use undo multicast-suppression to disable multicast storm suppression.

Syntax

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

undo multicast-suppression

Default

Ethernet interfaces do not suppress multicast traffic.

Views

Layer 2 Ethernet interface view

Predefined user roles

network-admin

context-admin

Parameters

ratio: Sets the multicast suppression threshold as a percentage of the interface bandwidth. The value range for this argument (in percentage) is 0 to 100. A smaller value means that less multicast traffic is allowed to pass through.

pps max-pps: Specifies the maximum number of multicast packets that the interface can forward per second. The value range for the max-pps argument (in pps) is 0 to 1.4881 × the interface bandwidth.

kbps max-kbps: Specifies the maximum number of kilobits of multicast traffic that the Ethernet interface can forward per second. The value range for this argument (in kbps) is 0 to the interface bandwidth.

Usage guidelines

The multicast storm suppression feature limits the size of multicast traffic to a threshold on an interface. When the multicast traffic on the interface exceeds this threshold, the system drops packets until the traffic drops below this threshold.

Both the storm-constrain command and the multicast-suppression command can suppress multicast storms on a port. The multicast-suppression command uses the chip to physically suppress multicast traffic. It has less influence on the device performance than the storm-constrain command, which uses software to suppress multicast traffic.

For the traffic suppression result to be determined, do not configure both the storm-constrain multicast command and the multicast-suppression command on an interface.

Examples

# Set the multicast storm suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] multicast-suppression kbps 10000

The actual value is 10048 on port GigabitEthernet1/0/1 currently.

The output shows that the value that takes effect is 10048 kbps (157 times of 64), because the chip only supports step 64.

Parameters

high-threshold high-value: Specifies the upper threshold for input bandwidth usage alarms, in the range of 1 to 100.

low-threshold low-value: Specifies the lower threshold for input bandwidth usage alarms, in the range of 1 to 100.

Usage guidelines

You can use the flow-interval command to set the statistics polling interval.

You can configure the input bandwidth usage alarm parameters in system view and interface view.

· The configuration in system view takes effect on all interfaces of the specified slot. The configuration in interface view takes effect only on the current interface.

· For an interface, the configuration in interface view takes priority, and the configuration in system view is used only when no configuration is made in interface view.

For this command to take effect, you must use the snmp-agent trap enable ifmonitor command to enable the input bandwidth usage alarm function.

When you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the upper threshold to 80 and lower threshold to 60 for input bandwidth usage alarms on GigabitEthernet 1/0/1.

Parameters

high-threshold high-value: Specifies the upper threshold for SDH error packet alarms, in the range of 1 to 4294967295 packets.

low-threshold low-value: Specifies the lower threshold for SDH error packet alarms, in the range of 1 to 4294967295 packets.

interval interval: Specifies the statistics collection and comparison interval for SDH error packets, in the range of 1 to 65535 seconds.

Usage guidelines

You can configure the SDH error packet alarm parameters in system view and interface view.

· The configuration in system view takes effect on all interfaces of the specified slot. The configuration in interface view takes effect only on the current interface.

· For an interface, the configuration in interface view takes priority, and the configuration in system view is used only when no configuration is made in interface view.

For this command to take effect, you must use the snmp-agent trap enable ifmonitor command to enable the SDH error packet alarm function.

When you execute this command multiple times, the most recent configuration takes effect.

Examples

# Set the upper threshold to 50, lower threshold to 30, and statistics collection and comparison interval to 10 seconds for SDH error packet alarms on GigabitEthernet 1/0/1.

Parameters

bridge: Specifies the Layer 2 mode.

route: Specifies the Layer 3 mode.

Usage guidelines

Interfaces operate differently depending on the hardware structure of interface cards. For a device:

· Some Ethernet interfaces can operate only as Layer 2 Ethernet interfaces (in bridge mode).

· Some Ethernet interfaces can operate only as Layer 3 Ethernet interfaces (in route mode).

· Some Ethernet interfaces can operate either as Layer 2 or Layer 3 Ethernet interfaces. You can use this command to set the link mode to bridge or route for these Ethernet interfaces.

Changing the link mode of an Ethernet interface also restores all commands (except shutdown and combo enable) on the Ethernet interface to their defaults in the new link mode.

auto: Enables the interface to negotiate a speed with its peer.

Usage guidelines

For an Ethernet copper port, use the speed command to set its speed to match the speed of the peer interface.

For fiber ports, only fiber ports 14 through 17 on the F1000-AI-60 and F1000-AI-70 devices support the auto and 1000 keywords of this command, and the other fiber ports support only the auto keyword of this command.

Support of an interface for the keywords depends on the interface type. For more information, use the speed ? command in interface view.

Examples

context-admin

Parameters

ratio: Sets the unknown unicast suppression threshold as a percentage of the interface bandwidth. The value range for this argument (in percentage) is 0 to 100. A smaller value means that less unknown unicast traffic is allowed to pass through.

pps max-pps: Specifies the maximum number of unknown unicast packets that the interface can forward per second. The value range for the max-pps argument (in pps) is 0 to 1.4881 × the interface bandwidth.

kbps max-kbps: Specifies the maximum number of kilobits of unknown unicast traffic that the Ethernet interface can forward per second. The value range for this argument (in kbps) is 0 to the interface bandwidth.

Usage guidelines

The unknown unicast storm suppression feature limits the size of unknown unicast traffic to a threshold on an interface. When the unknown unicast traffic on the interface exceeds this threshold, the system discards packets until the unknown unicast traffic drops below this threshold.

Examples

# Set the unknown unicast storm suppression threshold to 10000 kbps on GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] unicast-suppression kbps 10000

The actual value is 10048 on port GigabitEthernet1/0/1 currently.

The output shows that the value that takes effect is 10048 kbps (157 times of 64), because the chip only supports step 64.

storm-constrain

Use storm-constrain to enable storm control and set thresholds for broadcast, multicast, or unknown unicast packets on an Ethernet interface.

Use undo storm-constrain to disable storm control for broadcast, multicast, unknown unicast, or all types of traffic.

Syntax

storm-constrain { broadcast | multicast } pps upperlimit lowerlimit

undo storm-constrain { all | broadcast | multicast }

Default

Traffic storm control is disabled.

Parameters

all: Disables storm control for all types of traffic: multicast and broadcast.

broadcast: Enables or disables broadcast storm control.

multicast: Enables or disables multicast storm control.

pps: Sets storm control thresholds in pps.

upperlimit: Sets the upper threshold. If you specify the pps keyword, the value range for the upperlimit argument is 0 to 1.4881 × the interface bandwidth.

lowerlimit: Sets the lower threshold. If you specify the pps keyword, the value range for the lowerlimit argument is 0 to 1.4881 × the interface bandwidth.

Usage guidelines

After you configure storm control for a type of traffic, the device collects the statistics for the type of traffic at the interval configured by using the storm-constrain interval command. When the type of traffic exceeds its upper threshold, the interface takes an action configured by using the storm-constrain control command.

The storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storms on an interface. The broadcast-suppression, multicast-suppression, and unicast-suppression commands use the chip to physically suppress traffic. They have less influence on the device performance than the storm-constrain command, which uses software to suppress traffic.

For the traffic suppression result to be determined, do not configure both storm control and storm suppression for the same type of traffic.

When configuring this command, make sure upperlimit is greater than lowerlimit.

Examples

# Enable broadcast storm control on GigabitEthernet 1/0/1 and set the upper and lower thresholds to 200 pps and 150 pps, respectively.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

storm-constrain control

Use storm-constrain control to set the action to take on an Ethernet interface when a type of traffic (multicast or broadcast) exceeds the upper storm control threshold.

Use undo storm-constrain control to restore the default.

Syntax

storm-constrain control { block | shutdown }

undo storm-constrain control

Default

No action is taken on an Ethernet interface when a type of traffic exceeds the upper storm control threshold.

Parameters

block: Blocks the type of traffic exceeding the upper threshold and forwards other types of traffic. Even though the interface does not forward the blocked type of traffic, it still counts the traffic. When the blocked type of traffic drops below the lower threshold, the port begins to forward the traffic.

shutdown: Goes down automatically and stops forwarding any traffic. When the type of traffic exceeding the upper threshold drops below the lower threshold, the interface does not forward traffic. To bring up the interface, use the undo shutdown command or disable storm control on the interface.

Examples

# Configure GigabitEthernet 1/0/1 to block a specific type of traffic when the type of traffic exceeds the upper storm control threshold.

Default

Destination MAC filtering is enabled.

Predefined user roles

network-admin

Usage guidelines

This feature takes effect only on Layer 3 Ethernet interfaces/subinterfaces, Layer 3 aggregate interfaces, and Layer 3 Reth interfaces. These interfaces are referred to as interfaces in this command.

Typically, use the default settings.

With this feature enabled, when an interface receives a packet, the interface operates as follows:

· If the destination MAC address of the packet is the MAC address of the interface, the interface accepts and processes the packet.

· If the destination MAC address of the packet is not the MAC address of the interface, the interface drops the packet.

With this feature disabled, an interface accepts and processes a packet, without checking the destination MAC address of the packet.

Examples

# Enable destination MAC filtering.

Parameters

size: Sets the MTU in bytes. The value range for this argument varies by interface type.

Usage guidelines

A smaller MTU size results in more fragments. When you set the MTU for an interface, consider QoS queue lengths, for example, consider that the default FIFO queue length is 75. To prevent a too small MTU from causing packet drops in QoS queuing, you can perform one of the following configurations:

· Tune the MTU with the mtu command.

· Tune QoS queue lengths with the qos fifo queue-length command.

For more information about the qos fifo queue-length command, see ACL and QoS Command Reference.

Examples

# Set the MTU to 1430 bytes for GigabitEthernet 1/0/1.

<Sysname> system-view

[Sysname] interface gigabitethernet 1/0/1

[Sysname-GigabitEthernet1/0/1] mtu 1430

# Set the MTU to 1430 bytes for GigabitEthernet 1/0/1.1.
