Usage guidelines

This feature allows the device to check whether the VLAN ID of a flow matches that of any fast forwarding entry. If no match is found, the flow does not match any fast forwarding entry.

The VLAN ID of a packet helps the device to determine the TCP session to which the packet belongs. On a hot backup system formed by two firewalls, you must disable VLAN ID check if the traffic incoming interfaces on the primary and secondary devices belong to different VLANs. If you enable VLAN ID check, traffic cannot match session entries correctly when asymmetric-path traffic exists.

Examples

# Enable VLAN ID check for fast Layer 2 forwarding.

<Sysname> system-view

[Sysname] mac fast-forwarding check-vlan-id

cut-through enable

Use cut-through enable to enable cut-through forwarding.

Use undo cut-through enable to disable cut-through forwarding.

Syntax

cut-through enable

undo cut-through enable

Default

Cut-through forwarding is disabled.

Views

Predefined user roles

network-admin

context-admin

Usage guidelines

A cut-through forwarding-enabled device forwards a frame after it receives the first 64 bytes of the frame. This feature reduces the transmission time of a frame within the device and enhances forwarding performance.

A frame is forwarded before its CRC field is received, and thus CRC-error frames are forwarded instead of being dropped.

Examples

# Enable cut-through forwarding on the device.

<Sysname> system-view

[Sysname] cut-through enable

Bridge forwarding commands

add interface

Use add interface to add an interface to a reflect-type, forward-type, or blackhole-type bridge instance.

Use undo add interface to remove an interface from a reflect-type, forward-type, or blackhole-type bridge instance.

Syntax

add interface interface-type interface-number

undo add interface interface-type interface-number

Default

No interfaces exist in a reflect-type, forward-type, or blackhole-type bridge instance.

Views

Predefined user roles

network-admin

context-admin

Parameters

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

Usage guidelines

You can add only Layer 2 physical interfaces, Layer 3 physical interfaces, or Layer 2 aggregate interfaces to reflect-type, forward-type, or blackhole-type bridge instances.

Only one interface can be added to a reflect-type or blackhole-type bridge instance.

Only two interfaces can be added to a manually created forward-type bridge instance. The two interfaces must be the same type.

Each interface can be added to only one bridge instance.

This command is not available for a forward-type bridge instance that is automatically created upon insertion of a hardware bypass subcard. An automatically created forward-type bridge instance uses the pair of interfaces on the bypass subcard by default and you cannot edit the interfaces in the instance.

If you execute this command multiple times in reflect-type or blackhole-type bridge view, the most recent configuration takes effect.

If you execute this command multiple times in forward-type bridge view, the most recent two configurations take effect.

Examples

# Add GigabitEthernet 1/0/1 to reflect-type bridge instance 1.

<Sysname> system-view

[Sysname] bridge 1 reflect

[Sysname-bridge1-reflect] add interface gigabitethernet 1/0/1

add vlan

Use add vlan to add a list of VLANs to an inter-VLAN bridge instance.

Use undo add vlan to remove VLANs from an inter-VLAN bridge instance.

Syntax

add vlan vlan-id-list

undo add vlan [ vlan-id-list ]

Default

No VLANs exist in an inter-VLAN bridge instance.

Views

Inter-VLAN bridge view

Predefined user roles

network-admin

context-admin

Parameters

vlan-id-list: Specifies a space-separated list of up to 10 VLAN items. Each VLAN item specifies a VLAN ID or a range of VLAN IDs in the form of start-vlan-id to end-vlan-id. The end VLAN ID must be greater than the start VLAN ID. Valid VLAN IDs are from 1 to 4094.

Usage guidelines

You can add VLANs to a bridge instance before or after you create the VLANs.

You can add a VLAN to only one bridge instance.

If you execute the command multiple times, all configurations take effect.

If you do not specify the vlan-id-list argument, the undo add vlan command removes all VLANs from the inter-VLAN bridge instance.

Examples

# Add VLANs 2, 3, 5, and VLANs 50 through 70 to bridge instance 2.

<Sysname> system-view

[Sysname] bridge 2 inter-vlan

[Sysname-bridge2-inter-vlan] add vlan 2 3 5 50 to 70

bridge

Use bridge to create a specific type of bridge instance and enter its view, or enter the view of an existing bridge instance.

Use undo bridge to delete bridge instances.

Syntax

bridge bridge-index [ blackhole | forward | inter-vlan | reflect ]

undo bridge { bridge-index | all }

Parameters

bridge-index: Specifies a bridge instance index. For an automatically created forward-type bridge instance, the system will assign an index in the range of 32768 to 1082400.

blackhole: Specifies a blackhole-type bridge instance.

forward: Specifies a forward-type bridge instance.

inter-vlan: Specifies an inter-VLAN bridge instance.

reflect: Specifies a reflect-type bridge instance.

all: Deletes all bridge instances.

Usage guidelines

Use this command to create a bridge instance. You can create reflect-type, forward-type, and blackhole-type bridge instances for inline forwarding.

When you create a bridge instance, you must specify its type. You can specify only one type for a bridge instance.

The device will automatically create a forward-type bridge instance upon insertion of a hardware bypass subcard. The automatically created forward-type bridge instance uses the pair of interfaces on the bypass subcard by default. You cannot edit the interfaces in the bridge instance or delete the bridge instance.

In inline forwarding mode, tunneled packets are forwarded based on information in the tunnel encapsulation by default.

Use this command to enable the device to ignore the tunnel encapsulation and forward tunneled packets based on the original packet header information.

Examples

# Configure the device to ignore the tunnel encapsulation when forwarding tunneled packets in inline mode.

mac-address max-mac-count

Use mac-address max-mac-count to set the MAC learning limit on an inter-VLAN bridge instance.

Use undo mac-address max-mac-count to restore the default.

Syntax

Parameters

count: Sets the maximum number of MAC addresses that can be learned on an inter-VLAN bridge instance. The value range for this argument is 0 to 4096. To prevent an inter-VLAN bridge instance from learning any MAC addresses, set the limit to 0 for the bridge instance.

Usage guidelines

The command sets the size of the inter-VLAN bridge forwarding MAC address table. When the number of MAC address entries learned by an inter-VLAN bridge instance reaches the limit, the bridge instance stops learning MAC address entries.

Examples

# Configure inter-VLAN bridge instance 2 to learn a maximum of 10 MAC address entries.
