trill announcing-vlan

Use trill announcing-vlan to configure the announcing VLANs.

Use undo trill announcing-vlan to restore the default.

Syntax

trill announcing-vlan { vlan-list | null }

undo trill announcing-vlan { vlan-list | null }

Defaults

No announcing VLAN is configured. The announcing VLANs are the enabled VLANs.

Views

Layer 2 Ethernet interface view, Layer 2 aggregate interface view

Predefined user roles

network-admin

mdc-admin

Parameters

vlan-list: Specifies the announcing VLAN list that includes multiple announcing VLANs. The VLAN list is represented in the form of vlan-list = { vlan-id [ to vlan-id ] }&<1-10>, where vlan-id specifies a VLAN ID in the range of 1 to 4094 and &<1-10> indicates that you can specify up to ten { vlan-id [ to vlan-id ] } parameters.

null: Specifies that the announcing VLAN list does not include any VLANs.

Usage guidelines

Announcing VLANs forward Hello frames between RBs. The DRB uses the VLANs in the following set for sending Hello frames: enabled VLANs ∩ (announcing VLANs ∪ designated VLAN). A non-DRB uses the VLANs in the following set for sending Hello frames: enabled VLANs ∩ (designated VLAN ∪ (announcing VLANs ∩ forwarding VLANs)).

The concepts and symbols used in this section are explained as follows:

• Enabled VLAN—VLAN enabled on the port.

• Forwarding VLAN—VLANs for which an RBridge port is appointed VLAN forwarder on the port.

• ∩ and ∪—Set operation symbols. ∩ indicates set-theoretic intersection, and ∪ indicates set-theoretic union.

Configuration in Layer 2 Ethernet interface view takes effect on only the current port. Configuration in Layer 2 aggregate interface view takes effect on the current interface and its member ports. Configuration on the member port of an aggregate interface takes effect after the member port leaves the aggregation group.

Examples

# Configure VLANs 10 through 20 as the announcing VLANs.

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] trill announcing-vlan 10 to 20

# Specify the announcing VLAN list as null.

<Sysname> system-view
[Sysname] interface ten-gigabitethernet 1/0/1
[Sysname-Ten-GigabitEthernet1/0/1] trill announcing-vlan null
