Smart Link Device Configuration Example; Configuring An Associated Device; Enabling The Receiving Of Flush Messages - HP 4800G Series Configuration Manual

The control VLAN configured for a smart link group must be different from that configured for any
other smart link group.
Make sure that the configured control VLAN already exists, and assign the smart link group
member ports to the control VLAN.
Do not remove the control VLAN. Otherwise, flush messages cannot be sent properly.

Smart Link Device Configuration Example

Network requirements
Create smart link group 1.
The protected VLANs of smart link group 1 are mapped to MSTI 0 through 8.
Configure GigabitEthernet 1/0/1 as the master port of the smart link group, and GigabitEthernet
1/0/2 as the slave port.
Configure VLAN 20 for flush update.
Configuration procedure
<Sysname> system-view
[Sysname] vlan 20
[Sysname-vlan20] quit
[Sysname] interface gigabitethernet 1/0/1
[Sysname-GigabitEthernet1/0/1] undo stp enable
[Sysname-GigabitEthernet1/0/1] port link-type trunk
[Sysname-GigabitEthernet1/0/1] port trunk permit vlan 20
[Sysname-GigabitEthernet1/0/1] quit
[Sysname] interface gigabitethernet 1/0/2
[Sysname-GigabitEthernet1/0/2] undo stp enable
[Sysname-GigabitEthernet1/0/2] port link-type trunk
[Sysname-GigabitEthernet1/0/2] port trunk permit vlan 20
[Sysname-GigabitEthernet1/0/2] quit
[Sysname] smart-link group 1
[Sysname-smlk-group1] protected-vlan reference-instance 0 to 8
[Sysname-smlk-group1] port gigabitethernet 1/0/1 master
[Sysname-smlk-group1] port gigabitethernet 1/0/2 slave
[Sysname-smlk-group1] flush enable control-vlan 20
[Sysname-smlk-group1] quit

Configuring an Associated Device

Enabling the Receiving of Flush Messages

You do not need to enable all ports on the associated devices to receive flush messages sent from the
transmit control VLAN, only those on the master and slave links between the smart link device and the
destination device.
