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 126 for a 50G interface and 1 to 254 for a 100G interface.

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.

· On an RX-NIC-CQ1LF or RX-NIC-CQ2LF subcard, only one FlexE physical interface can be added to a FlexE group interface.

· On an RX-NIC-LGQ2L or RX-NIC-LGQ4L subcard, up to two FlexE physical interfaces can be added to a FlexE group interface. The member interface numbers must be 1 and 2, 3 and 4, 5 and 6, or 7 and 8.

· 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.

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-HundredGigE 3/1/1 to FlexE-group 3/1/1 and set the PHY number of the FlexE physical interface to 2.

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: Specifies the bandwidth of the FlexE logical interface directly in Gbps. The value range is 5 to 4194303, and the step is 5.

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 Gbps.

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

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 3/1/1, the device creates FlexE logical interface FlexE3/1/1:10 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 FlexE3/1/1:10 and set its bandwidth to 10 Gbps.

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.

Do not enable the dampening function on an interface with MSTP enabled.

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

Examples

# Enable interface dampening on FlexE-HundredGigE 3/1/1.

Parameters

slot slot-number: Specifies a card by its slot number. (In standalone mode.)

chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The chassis-number argument represents the member ID of the IRF member device. The slot-number argument represents the slot number of the card. (In IRF mode.)

subslot subslot-number: Specifies a subcard by its slot number.

bandwidth: Specifies the bandwidth mode as the bandwidth configuration mode of FlexE logical interfaces. In this mode, you can flexibly set the bandwidth of a FlexE logical interface.

timeslot: Specifies the timeslot mode as the bandwidth configuration mode for FlexE logical interfaces. In this mode, you can set the bandwidth of a FlexE logical interface by binding timeslots with the specified timeslot granularity of a FlexE physical interface to it.

Usage guidelines

You can set the bandwidth configuration mode for FlexE logical interfaces to bandwidth mode or timeslot mode.

· 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. In this mode, you can set different bandwidth for FlexE logical interfaces at both ends.

· If the bandwidth configuration mode is timeslot mode, you can only use the client client-id binding interface interface-type interface-number timeslot timeslot-list command to set the bandwidth of FlexE logical interfaces. In this mode, you must bind the timeslots of the same FlexE physical interfaces to FlexE logical interface at both ends. The timeslots of the FlexE physical interface bound to the FlexE logical interfaces at both end can be different.

If you already set the bandwidth of a FlexE logical interface by using the client command, you cannot change the bandwidth configuration mode by using this command.

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 3/1/1 and enter its view.

<Sysname> system-view

[Sysname] interface flexe-group 3/1/1

[Sysname-FlexE-Group3/1/1]

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 is 0 to 1200 seconds.

· 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 3/1/1.

Predefined user roles

network-admin

Parameters

auto: Autonegotiates the FEC mode or disables FEC according to the transceiver module type.

none: Performs no FEC.

rs-fec: Specifies the RS-FEC mode.

Usage guidelines

This command is supported only on CEPC-CQ8L, RX-NIC-CQ1LF, and RX-NIC-CQ2LF subcards.

The FEC feature corrects packet errors to improve transmission quality. It attaches correction information to a packet at the sending end, and corrects error codes generated during transmission at the receiving end based on the correction information. You can set the FEC mode as needed.

Make sure you set the same FEC mode for both interfaces of a link.

For transceiver modules that support FEC, you can specify the auto, none, or rs-fec keywords. For transceiver modules that does not support FEC, their interfaces do not correct forward errors.

The following compatibility matrix shows the support of the transceiver module models for FEC:

Model	FEC compatibility
100G_CWDM4_FEC_QSFP28	Yes
100G_PSM4_QSFP28	Yes
