Parameters

interface-type interface-number: Specifies a FlexE physical interface by its type and number.

phy-number number: Specifies the PHY number of the FlexE physical interface, in the range of 1 to 254.

Usage guidelines

When you add a FlexE physical interface to a FlexE group interface, follow these restrictions and guidelines:

· You can add a FlexE physical interface only to a FlexE group interface.

· For correct communication between FlexE physical interfaces at both of the ends of a link, you must add the FlexE physical interfaces to the same FlexE group interface. Make sure the FlexE physical interfaces have the same PHY number.

· You can repeat this command to add multiple FlexE physical interfaces to a FlexE group interface. Make sure the PHY number for each FlexE physical interfaces is unique in a FlexE group interface.

If the bandwidth or timeslots of a FlexE physical interface have been bound to a FlexE logical interface, you cannot the following tasks:

· Remove the FlexE physical interface from the FlexE group interface.

· Change the PHY number of the FlexE physical interface.

Examples

# Add FlexE-100G 1/0/1 to FlexE-group 1/0/1 and set the PHY number of the FlexE physical interface to 2.

<Sysname> system-view

Default

A FlexE logical interface does not suppress broadcast traffic.

Views

Predefined user roles

network-admin

Parameters

ratio: Specifies 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 FlexE logical 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 FlexE 1/0/1:1.

<Sysname> system-view

[Sysname] interface flexe 1/0/1:1

[Sysname-FlexE1/0/1:1] broadcast-suppression kbps 10000

The actual value is 10048 on port FlexE1/0/1:1 currently.

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

Parameters

client-id: Specifies the client ID of the FlexE group interface to be created, in the range of 1 to 65534. The interface number of the FlexE logical interface is in the form of FlexE-group-interface-number:client-ID.

bandwidth { bandwidth-value | 1 | 1.25 | 2 | 2.5 | 3 | 3.75 | 4 }: Specifies the bandwidth of the FlexE logical interface directly.

· bandwidth-value: Specifies the bandwidth, in GB. The value range is 5 to 4194303, and the step is 5.

· 1: Specifies the bandwidth of 1 GB.

· 1.25: Specifies the bandwidth of 1.25 GB.

· 2: Specifies the bandwidth of 2 GB.

· 2.5: Specifies the bandwidth of 2.5 GB.

· 3: Specifies the bandwidth of 3 GB.

· 3.75: Specifies the bandwidth of 3.75 GB.

· 4: Specifies the bandwidth of 4 GB.

bind interface interface-type interface-number timeslot timeslot-list: Specifies the bandwidth of the FlexE logical interface based on timeslots. You can bind timeslots of a FlexE physical interface to the FlexE logical interface. The bandwidth of the FlexE logical interface is timeslot-count × 5 GB.

· interface-type interface-number: Specifies the FlexE physical interface by it type and number.

· timeslot-list: Specifies a comma-separated list of timeslot items. Each item specifies a timeslot by its ID or a range of timeslots in the form of start_timeslot-end_timeslot. For example, 1,3-5. The maximum length of the timeslot list is 31 characters. The value range of timeslot IDs depend on FlexE physical interface type.

¡ For FlexE-50G interfaces, the value range for the timeslot ID is 0 to 9. Each timeslot represent bandwidth of 5 GB.

¡ For FlexE-100G interfaces, the value range for the timeslot ID is 0 to 19. Each timeslot represents bandwidth of 5 GB.

Usage guidelines

Use this command to set the client ID for a FlexE logical interface to be created and create the FlexE logical interface in a FlexE group interface. The interface number of the FlexE logical interface is in the format of FlexE-group-interface-number:client ID. For example, after you execute the client-id 10 command in the view of FlexE-Group 1/0/1, the device creates FlexE logical interface FlexE1/0/1:10 in which 10 is the client ID.

You can set the bandwidth of a FlexE logical interface in bandwidth or timeslot configuration mode set by using the flexe config-mode command in system view.

· If the bandwidth configuration mode is bandwidth mode, you can only use the client client-id bandwidth command to set the bandwidth of the FlexE logical interface.

For correct communication between FlexE logical interfaces at both ends of a link, you must perform the following tasks:

· Create a FlexE group interface at both of the devices.

· Set the same client ID for the two FlexE group interfaces.

Examples

# Create FlexE logical interface FlexE1/0/1:10 and set its bandwidth to 10 GB.

Parameters

client-channel-id: Specifies a client channel by its ID in the range of 1 to 65534. The client channel ID cannot be the same as a client ID in the FlexE-group interface view.

bandwidth bandwidth-value: Directly specifies the bandwidth for the client channel. The bandwidth-value argument specifies the client channel bandwidth in the range of 5 to 4194303 in Gbps. The bandwidth must in the step of 5.

interface interface-type interface-number timeslot timeslot-list: Assigns bandwidth to the client channel through specifying timeslots.

· The interface-type interface-number argument specifies a FlexE physical interface by its type and number. Make sure the specified interface has been assigned to the FlexE-group interface.

· The timeslot-list argument specifies a timeslot ID list, for example, 1,3-5. Use a hyphen (-) to specify a timeslot ID range, and separate multiple timeslot IDs or ranges by using commas (,). A timeslot ID list can contain up to 31 characters. The value range for this argument varies by the bandwidth of the specified FlexE physical interface.

¡ For a FlexE-50G interface, the timeslot ID is in the range of 0 to 9, and a timeslot represents bandwidth of 5 Gbps.

¡ For a FlexE-100G interface, the timeslot ID is in the range of 0 to 19, and a timeslot represents bandwidth of 5 Gbps.

Usage guidelines

To allocate bandwidth at the granularity of 10 Mbps, you can create client channels in a FlexE-group interface. Then, you can create FlexE logical interfaces of smaller bandwidth in a client channel.

When you create a client channel for the first time, you must allocate bandwidth to the client channel.

For FlexE logical interfaces on two ends of a link to communicate normally, perform the following tasks on both ends:

· Create FlexE-group interfaces with the same number.

· In the FlexE-group interface, configure the same client channel ID, and configure the same bandwidth allocation mode for the client channel.

· In the client channel, configure the same client ID.

Examples

# Configure client channel ID 2, and allocate bandwidth of 10 Gbps to the client channel.

Parameters

interface-type interface-number: Specifies a FlexE logical interface by its type and name.

Usage guidelines

FlexE physical interfaces cannot process protocol messages for the clock service. To deploy the clock service (such as PTP) on a FlexE physical interface, you must bind the FlexE physical interface to a FlexE logical interface that hosts the clock service.

For the clock service to correctly operate between two devices, set the same client ID for the interconnecting FlexE logical interfaces at both ends.

If the bound FlexE interface fails, the clock service will be affected. To resolve the issue, bind the FlexE physical interface to another FlexE logical interface. During the rebinding process, the clock service is unavailable.

Examples

# Bind FlexE physical interface FlexE-HundredGigE 1/0/1 to FlexE logical interface FlexE 1/0/1:1 hosting the clock service.

Predefined user roles

network-admin

Parameters

bandwidth: Specifies the fine granularity bandwidth-based mode, which allows you to flexibly configure bandwidth.

sub-timeslot: Specifies the sub-timeslot-based mode, which allows you to allocate bandwidth by specifying sub-timeslots at the granularity of 10 Mbps.

Usage guidelines

To meet the differentiated service carrying requirements for small bandwidth, high isolation, and high security in the 5G+vertical industry application scenarios and private line service scenarios, you must provide carrier channels with lower granularity. The fine granularity unit (FGU) technique refines the granularity from 5 Gbps to 10 Mbps to provide carrier channels with low costs, small granularity, and hardware isolation to meet the requirements of 5G+vertical industry application scenarios and government/organization private line scenarios.

In the current software version, you can configure bandwidth at the granularity of 10 Mbps for FlexE-FG10G interfaces and client channels. Use this command to configure the bandwidth allocation mode for a fine granularity FlexE logical interface.

You can configure bandwidth for a fine-granularity FlexE logical interface flexibly or through specifying sub-timeslots with the specified granularity.

· When the bandwidth allocation mode is bandwidth-based, execute the fg-client fg-client-id bandwidth bandwidth-value command to configure bandwidth flexibly for a FlexE-FG10G interface.

· When the bandwidth allocation mode is sub-timeslot-based, execute the fg-client fg-client-id timeslot timeslotlist command to specify sub-timeslots with the granularity of 10 Mbps for a FlexE-FG10G interface.

If you have used the fg-client fg-client-id bandwidth bandwidth-value or fg-client fg-client-id timeslot timeslotlist command to configure bandwidth for a FlexE-FG10G interface or client channel, you cannot modify the bandwidth allocation mode for the FlexE-FG10G interface.

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

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.

As a best practice, do not enable the dampening function on an interface with RRPP, MSTP, 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.

Usage guidelines

With TxRx-mode generic flow control configured, a FlexE logical interface can both send and receive flow control frames:

· When congested, the interface sends a flow control frame to its peer.

· Upon receiving a flow control frame from the peer, the interface suspends sending packets.

To implement flow control on a link, enable generic flow control at both ends of the link.

Examples

# Enable TxRx-mode generic flow control on FlexE logical interface FlexE 1/0/1:1.

<Sysname> system-view

[Sysname] interface flexe 1/0/1:1

[Sysname-FlexE1/0/1:1] flow-control

Use flow-control receive enable to enable Rx-mode generic flow control on a FlexE logical interface.

Use undo flow-control to disable Rx-mode generic flow control on a FlexE logical interface.

Syntax

flow-control receive enable

undo flow-control

Default

Rx-mode generic flow control is disabled on a FlexE logical interface.

Views

FlexE logical interface view

Predefined user roles

network-admin

Usage guidelines

With Rx-mode flow control enabled, a FlexE logical interface can receive but cannot send flow control frames.

· When the interface receives a flow control frame from its peer, it suspends sending packets to the peer.

· When traffic congestion occurs on the interface, it cannot send flow control frames to the peer.

To handle unidirectional traffic congestion on a link, configure the flow-control receive enable command at one end, and the flow-control command at the other. To enable both ends of the link to handle traffic congestion, configure the flow-control command at both ends.

Examples

# Enable Rx-mode generic flow control on FlexE logical interface FlexE 1/0/1:1.

Parameters

fg-client-id: Specifies an FG client ID (FlexE-FG10G logical interface number) on a FlexE logical interface. The value range for this argument varies by device model.

bandwidth bandwidth-value: Directly specifies bandwidth for a FlexE logical interface. The bandwidth-value argument specifies bandwidth for a FlexE logical interface. The value range varies by the bandwidth allocated to the client channel. The bandwidth is in the step of 10 in Mbps.

timeslot timeslot-list: Specifies bandwidth for a FlexE logical interface by specifying sub-timeslots. The timeslot-list argument specifies a sub-timeslot ID list, for example, 1,3-5. Use a hyphen (-) to specify a sub-timeslot ID range, and separate multiple sub-timeslot IDs or ranges by using commas (,). A sub-timeslot ID list can contain up to 24 characters. Only full data configuration is supported. The value range for this argument varies by the bandwidth allocated to the client channel. A sub-timeslot represents bandwidth of 10 Mbps.

Usage guidelines

When you use this command to configure a FG client ID, the system will automatically create a FlexE logical interface with the same number. For example, if you configure FG client ID 10 on FlexE-FG10G 2/2/1, the system will automatically create FlexE logical interface FlexE2/2/1/0:10.

You can also use this command to configure the bandwidth for a FlexE logical interface. You can configure bandwidth for a FlexE logical interface flexibly or through specifying sub-timeslots with the specified granularity.

· When the config-mode bandwidth command is used to configure the bandwidth allocation mode as bandwidth-based, you can only execute the fg-client fg-client-id bandwidth command to configure bandwidth flexibly for a FlexE logical interface.

· When the config-mode sub-timeslot command is used to configure the bandwidth allocation mode as sub-timeslot-based, you can only execute the fg-client fg-client-id timeslot timeslot-list command to specify sub-timeslots for a FlexE logical interface. The bandwidth of the FlexE logical interface is the number of sub-timeslots multiplied by the sub-timeslot granularity.

For FlexE-FG10G logical interfaces on two ends of a link to communicate normally, perform the following tasks on both ends:

· For PHY-level fine granularity slices, configure the same FG client ID on the FlexE-FG10G interfaces.

· For FlexE-level fine granularity slices, perform the following tasks:

¡ Create FlexE-group interfaces with the same number.

¡ In the FlexE-group interface, configure the same client channel ID, and configure the same bandwidth allocation mode for the client channel.

¡ In the client channel, configure the same FG client ID.

Examples

# On a PHY-level fine granularity slice, configure FG client ID 10, create FlexE-FG10G logical interface FlexE 2/2/1/0:10 with the same ID, and assign bandwidth of 50 Mbps to the interface.

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

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

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

shutdown: Shuts down an interface when the number of incoming CRC 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 CRC error packets exceeds the upper threshold on the interface.

slot slot-number: Specifies a card by its slot number.

Usage guidelines

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. The configuration in interface view takes effect only on the current interface. (Devices that do not support the slot keyword.)

· 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. (Devices that support the slot keyword.)

· 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.

This command takes effect only when the CRC error packet alarm function is enabled by using the snmp-agent trap enable ifmonitor crc-error command.

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

In FlexE-DCN interface view, you can configure the following LLDP features to implement DCN:

· LLDP operating mode.

· LLDP function.

· Configuring the interface to generate ARP or ND entries after receiving LLDP frames carrying the management address TLVs.

· Advertisable TLVs on the interface.

For more information about LLDP, see LLDP in Layer 2—Ethernet Switching Configuration Guide.

Examples

# Enter the view of interface FlexE-DCN 1/0/1.

<Sysname> system-view

[Sysname] interface flexe-dcn 1/0/1

[Sysname-FlexE-DCN1/0/1]

interface flexe-group

Predefined user roles

network-admin

Parameters

interface-number: Specifies the interface number of the FlexE group interface. The last tier in the interface number represents the group number of the FlexE group interface.

Usage guidelines

After you create a FlexE group interface, you can add multiple FlexE physical interfaces to the FlexE group interface and create FlexE logical interfaces in the FlexE group interface as needed. Then, you can flexibly assign the total bandwidths of the FlexE physical interfaces to FlexE logical interfaces according to the bandwidth requirements of services.

The number of FlexE group interface must be equal to or smaller than the number of FlexE physical interfaces on the subslot.

You can delete a FlexE group interface only if the FlexE group interface does not have any FlexE physical or logical interfaces.

Examples

# Create FlexE group interface FlexE-Group 1/0/1 and enter its view.

<Sysname> system-view

[Sysname] interface flexe-group 1/0/1

[Sysname-FlexE-Group1/0/1]

Predefined user roles

network-admin

Parameters

down: Suppresses link-down events.

up: Suppresses link-up events.

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: Specifies the physical state change suppression interval on the FlexE 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 for this argument varies by device model.

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

Usage guidelines

You can use this command 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.

On an interface, you can set different suppression intervals for link-up and link-down events. If you set the suppression interval multiple times for the same type of link suppression events, the most recent configuration takes effect.

Examples

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

<Sysname> system-view

[Sysname] interface flexe 1/0/1:1

[Sysname-FlexE1/0/1:1] link-delay down 8

Parameters

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

Usage guidelines

The MTU set by using this command or the ip mtu command takes effect only on packets that the interface delivers to the CPU, for example, packets originated from or destined for the interface. Set a reasonable MTU on the interface to avoid fragmentation.

If you configure both the mtu and ip mtu commands on the interface, the MTU set by using the command takes priority.

Examples

# Set the MTU to 1430 bytes for FlexE logical interface FlexE 1/0/1:1.

<Sysname> system-view

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

undo multicast-suppression

Default

A FlexE logical interface does not suppress multicast traffic.

Views

FlexE logical interface view

Predefined user roles

network-admin

Parameters

ratio: Specifies 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 FlexE logical 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 FlexE logical interface can forward per second. The value range for this argument (in kbps) is 0 to the interface bandwidth.

unknown: Enables multicast storm suppression only on unknown packets. If you do not specify this keyword, packets suppressed by this feature depend on the device model.

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 FlexE logical interface FlexE 1/0/1:1.

<Sysname> system-view

[Sysname] interface flexe 1/0/1:1

[Sysname-FlexE1/0/1:1] multicast-suppression kbps 10000

The actual value is 10048 on port FlexE1/0/1 currently.

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

Usage guidelines

When an interface with auto power-down enabled has been down for a specific period of time, both of the following events occur:

· The device automatically stops supplying power to the interface.

· The interface enters the power save mode.

The time period depends on the chip specifications and is not configurable.

When the interface comes up, both of the following events occur:

· The device automatically restores the power supply to the interface.

· The interface restores to its normal state.

Examples

# Enable auto power-down on FlexE logical interface FlexE 1/0/1:1.

network-admin

Parameters

high-threshold high-value: Specifies the upper threshold for SDH-B2 error packet alarms, in the range of 1 to 4294967295 packets.

low-threshold low-value: Specifies the lower threshold for SDH-B2 error packet alarms, in the range of 1 to 4294967295 packets.

interval interval: Specifies the statistics collection and comparison interval for SDH-B2 error packets, in the range of 1 to 65535 seconds.

Usage guidelines

With the SDH-B2 error packet alarm function enabled, when the number of incoming SDH-B2 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-B2 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-B2 error packet alarm parameters in system view and interface view.

· The configuration in system view takes effect on all interfaces. The configuration in interface view takes effect only on the current interface. (Devices that do not support the slot keyword.)

· 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.

This command takes effect only when the incoming pause frame alarm function is enabled by using the snmp-agent trap enable ifmonitor sdh-b2-error command.

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

Examples

# Set the upper threshold to 10, lower threshold to 8, and statistics collection and comparison interval to 3 seconds for SDH-B2 error packet alarms on FlexE 1/0/1:1.

CAUTION:

After the type of an interface is changed, the system deletes the original interface and creates a new interface that is numbered the same as the original interface. All the other commands are restored to the default on the new interface.

‌

The bandwidth of an interface in standard Ethernet mode is fixed, and the bandwidth of an interface in FlexE mode can be flexibly specified.

· To assign bandwidth at the granularity of 5 Gbps, execute the port-type flexe command to switch the type of the interface from Ethernet to FlexE.

· To assign bandwidth at the granularity of 10 Mbps, execute the port-type flexe-fg command to switch the type of the interface from Ethernet to fine granularity FlexE.

If a FlexE physical interface has been added to a FlexE group interface and bandwidth has been assigned to a FlexE logical interface in the group, you cannot change the interface type.

Examples

# Change standard Ethernet interface FiftyGigE 1/0/1 to a FlexE interface.

<Sysname> system-view

[Sysname] interface fiftygige 1/0/1

[Sysname-FiftyGigE1/0/1] port-type flexe

Views

FlexE logical interface view

Predefined user roles

network-admin

Parameters

auto: Specifies PFC in auto mode. In this mode, the local end automatically negotiates the PFC status with the remote end.

enable: Forcibly enables PFC.

Usage guidelines

The local device notifies the remote end to stop sending packets carrying the specified 802.1p priority if all of the following conditions exist:

· Both the local end and the remote end have PFC enabled.

· Both the local end and the remote end have the priority-flow-control no-drop dot1p command configured.

· The specified 802.1p priority is in the 802.1p priority list specified by the dot1p-list argument.

· The local end receives packets carrying the specified 802.1p priority, and the received packets cause congestion.

When congestion is eliminated, the local end notifies the remote end to continue to send packets carrying the specified 802.1p priority. In this way, the local device can forward packets carrying 802.1p priorities in the specified 802.1p priority list without packet drops.

Examples

# Enable PFC in auto mode on FlexE logical interface FlexE 1/0/1:1.

Predefined user roles

network-admin

Parameters

dot1p-list: Specifies an 802.1p priority (or dot1p priority) list to identify flows that are subject to PFC (for example: 1,3-5). A hyphen (-) connects two numeric values, which together indicate a continuous value range. Different values or value ranges are separated with commas (,). You can configure up to 16 characters for this argument.

Usage guidelines

The local device notifies the remote end to stop sending packets carrying the specified 802.1p priority if all of the following conditions exist:

· Both the local end and the remote end have PFC enabled.

· Both the local end and the remote end have the priority-flow-control no-drop dot1p command configured.

· The specified 802.1p priority is in the 802.1p priority list specified by the dot1p-list argument.

· The local end receives packets carrying the specified 802.1p priority, and the received packets cause congestion.

If you configure the flow control or flow-control receive enable command on a PFC-enabled device or interface, the following events occur:

· The PFC configuration takes effect.

· The configuration of the flow control or flow-control receive enable command is ignored.

· The flow control or flow-control receive enable command takes effect on the device or interface only when PFC is disabled on it.

Examples

# Enable PFC in auto mode on FlexE logical interface FlexE 1/0/1:1, and enable PFC for 802.1p priority 5.

Parameters

50ge: Specifies the speed of 50 Gbps.

100ge: Specifies the speed of 100 Gbps.

Usage guidelines

Assume that an interface module has only two interfaces A and B and that A has a smaller interface number than B. When you change the speed mode of the interfaces, follow these restrictions:

· If both A and B operate at a speed of 50 Gbps, you can change only the speed mode of A to 100 Gbps. After the speed mode of A changes, B will be deleted.

· If you change the speed mode of A from 100 Gbps to 50 Gbps, B will be created and will operate at a speed of 50 Gbps.

· If A or B has been added to a FlexE group interface, you cannot directly change its speed mode. Before changing the speed mode, remove the interface from the FlexE group interface.

· If A operates at a speed of 50 Gbps and B has been added to a FlexE group interface, you cannot directly change the speed mode of A. Before changing the speed mode of A, you must remove B from the FlexE group interface.

To display the speed mode of an interface, use the display interface command.

Examples

# Configure Fifty-HundredGigE 1/0/1 to operate at a speed of 50 Gbps.

<Sysname> system-view

Default

The speed of an interface is determined by the transceiver module installed.

Predefined user roles

network-admin

Parameters

manual: Sets the speed mode to manual for the 50-100GE interface.

Usage guidelines

Suppose two interfaces on an expansion interface card operate at 50 Gbps. After you execute the switch-mode manual mode on an interface, you can execute the speed-mode 100ge command to configure the interface to operate at 100 Gbps. At the same time, the other interface will be deleted. To view the interface changes, execute the display interface brief command.

If an interface on an expansion interface card is a FlexE interface operating at 100 Gbps and has been assigned to a FlexE group, you cannot configure the interface to operate at 50 Gbps. To do that, first remove it from the FlexE group.

After you execute this command on an interface, you must use the speed-mode command to manually specify a speed mode for the interface.

Examples

# Configure interface Fifty-HundredGigE 1/0/1 to operate in manual mode.

<Sysname> system-view

[Sysname] interface fifty-hundredgige 1/0/1

unicast-suppression

Use unicast-suppression to enable unknown unicast storm suppression and set the unknown unicast storm suppression threshold.

Use undo unicast-suppression to disable unknown unicast storm suppression.

Syntax

undo unicast-suppression

Default

A FlexE logical interface does not suppress unknown unicast traffic.

Views

FlexE logical interface view

Predefined user roles

network-admin

Parameters

ratio: Specifies 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 FlexE logical 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.

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

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

Examples

# Set the unknown unicast storm suppression threshold to 10000 kbps on FlexE logical interface FlexE 1/0/1:1.

<Sysname> system-view

[Sysname] interface flexe 1/0/1:1

[Sysname-FlexE1/0/1:1] unicast-suppression kbps 10000

The actual value is 10048 on port FlexE1/0/1:1 currently.

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