trill announcing-vlan
Use trill announcing-vlan to configure announcing VLANs.
Use undo trill announcing-vlan to remove the specified announcing VLANs.
Syntax
trill announcing-vlan { vlan-list | null }
undo trill announcing-vlan { vlan-list | null }
Default
No announcing VLAN is configured. Announcing VLANs are enabled VLANs.
Views
Layer 2 Ethernet interface view
Layer 2 aggregate interface view
Predefined user roles
network-admin
mdc-admin
Parameters
vlan-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 vlan-id1 to vlan-id2. The value range for VLAN IDs is 1 to 4094. The value for the vlan-id2 argument must be equal to or greater than the value for the vlan-id1 argument.
null: Configure the announcing VLAN list as empty.
Usage guidelines
RBs send Hello frames in a set of VLANs. The VLAN set is calculated as follows:
DRB—Enabled VLANs ∩ (announcing VLANs ∪ designated VLAN).
Non-DRB—Enabled VLANs ∩ (designated VLAN ∪ (announcing VLANs ∩ forwarding VLANs)).
To prevent Hello frames from consuming excessive CPU resources, reduce the number of announcing VLANs.
Configuration in Layer 2 Ethernet interface view takes effect only on 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
# Set VLANs 10 through 20 to announcing VLANs.
<Sysname> system-view [Sysname] interface [Sysname-] trill announcing-vlan 10 to 20
# Set the announcing VLAN list to empty.
<Sysname> system-view [Sysname] interface [Sysname-] trill announcing-vlan null
