Wherein, logon message and probe messages are distinguished as：
(1) logon message includes control VLAN and forwarding is forbidden to configure；Probe messages include control VLAN and protection VLAN.
(2) logon message can be sent port corresponding to the main/slave link by source device respectively, and probe messages are only
It can the transmission of the port corresponding to primary link or standby link.
Standby link is switched to new primary link by step S303, source device, and source device is sent by new primary link comprising control
The FLUSH message of VLAN, so that the forwarding device option and installment connecting with new primary link includes the second filter table of control VLAN
The port of item forwards FLUSH message.
It should be noted that periodicity sending when due to logon message and probe messages, then register when across period transmission and report
Text and when probe messages, it may appear that the problem of the covering and update of the first filtering meter item and the second filtering meter item, below with reference to
Specific application scenarios, in the same SMART-LINK group the first filtering meter item and the second filtering meter item across period assignment
It is described in detail.
(1) when current configured second filtering meter item of the receiving port of logon message；
When configured second filtering meter item of the receiving port of logon message, forwarding device is according to the control in logon message
VLAN processed to first filtering meter item of the receiving port configuration comprising control VLAN of logon message, and is covered with the first filtering meter item
The second filtering meter item of lid.
As shown in Figure 1, if the Port 2 of Device E before receiving logon message, according to Device E's
Port1 it is received control VLAN be 10 the second filtering meter item, then 2 port Port of Device E receive control VLAN be
When 10 logon message, the first filtering meter item that control VLAN is 10 is configured for the port, meanwhile, which covers it
Second filtering meter item of preceding configuration.
(2) when the receiving port of probe messages is configured with the first filtering meter item；
When forwarding device is received by the port configured with the first filtering meter item comprising controlling VLAN comprising control
When the probe messages of VLAN, forwarding device traverses itself port, configure allow in port by VLAN in comprising probe messages
Protection VLAN and be not configured the first filtering meter item port the second filtering meter item；
As shown in Figure 1, if Device B receives the logon message for being 10 comprising control VLAN by 3 port Port,
And after being configured with the first filtering meter item that control VLAN is 10, being had received again by 3 port Port includes that control VLAN is
10, the probe messages that protection VLAN is 10-30, then Device B traverses itself port, discovery Port 3, Port 2 and Port 1
Allow by VLAN include 10-30, then Device B selects Port 2 and Port1 to forward probe messages, and to 2 He of Port
The second filtering meter item that Port1 configuration control VLAN is 10.

When forwarding device is received by being not configured with the port of the first filtering meter item comprising control VLAN comprising control
When the probe messages of VLAN, forwarding device configuration pin traverses itself to the second filtering meter item of the receiving port of probe messages
Port, configure allow in other ports by VLAN in comprising probe messages protection VLAN and the first filtering meter item is not configured
Port the second filtering meter item.
As shown in Figure 1, it is 10 that the Port 1 of Device A, which is received comprising control VLAN, the spy that protection VLAN is 10-30
Text is observed and predicted, then Device A is the second filtering meter item that the configuration control of Port 1 VLAN is 10；And itself port is traversed, find it
In his port Port 2 allow by VLAN include 10-30, then Device A selects Port 2 to forward probe messages, and right
The second filtering meter item that the configuration control of Port 2 VLAN is 10.And the Port3 of Device A is configured with and terminates SMART-LINK's
Hong Fan, therefore it is no longer thought of as the configurating filtered list item in the port, it is of course also possible to after configuring the second filtering meter item, to reception
To FLUSH message carry out termination flooding.
It should be noted that when the control VLAN change in the logon message and probe messages that source device is sent, forwarding
Equipment can find the first filtering meter item to be updated and the second filtering according to the source MAC in logon message and probe messages
