Huawei Hrbrid interface and VLAN division based on IP

untag list

The switch interface can be set untag list , When data goes out of the interface , Will view untag surface , If there is a corresponding label in the table , Will take off the label , Let go of the data . If there is no corresponding label in the table , Will view tag surface . If there is a corresponding label , It will release , If it does not exist , Then discard the data .

tag list

The switch interface can be set tag list , When data enters the interface is , Will check whether the data has labels , If there is no label , Will be marked with PVID label , Let go , If there is a label , Will view tag Whether there is a corresponding label in the table , If exist , Then release , If not, discard .

PVID

The switch interface can be set PVID, When data enters the interface , Will check whether the data has labels , If there is no label , Will be marked with PVID label , Let go , If there is a label , Will view tag surface .

be based on IP Of VLAN Divide
 

PS： This function is only supported in Huawei hybrid On the interface

command ： vlan Under View ：ip-subnet-vlan ip [ Network segment | Single IP Address ]

Take the example above ,Server1 and Server2 be located vlan1 Of access Interface ,Server3 The interface is located at vlan10 The interface of , Now? sw2 The configuration cannot be modified because of the problem , Need to be in sw1 To configure , take Server1 and Server2 The flow rate of vlan10 and vlan20 Traffic forwarded to CoreSwitch On . and Server3 Just release its traffic .

SW2 Configuration on  

1、 The direct connection interface with the three servers should be changed into access Interface , At the same time, its default vlan The division is consistent with the requirements  

2、Sw2 And Sw1 The interface type of the directly connected interface is changed to trunk mouth , And release vlan30,Server1 and Server2 The flow of will be in the form of no label from Sw2 Forward to Shanglian Sw1 On , then Sw1 According to the corresponding IP by Server1 and Server2 The flow rate of is marked with the corresponding label .

SW1 Configuration on

1、 Will be in Sw2 The interface type of direct connection is changed to hybrid, At the same time, enter port hybrid tagged vlan 30 ,port hybrid untagged vlan 10 20. When these two items are entered , All from coreswitch Forwarded vlan10 and vlan20 The label will be removed on this interface , At the same time, because the interface port hybrid tagged vlan 30 The reason of the order , all vlan30 Traffic will be allowed to pass through this interface .

2、 stay vlan10 View configuration ：ip-subnet-vlan ip 10.10.10.1 24 , stay vlan20 View configuration ：ip-subnet-vlan ip 10.10.20.1 24, When these two commands are entered , When there is corresponding IP When the flow passes , Will be the corresponding IP Label it accordingly .

2、 take Sw2 And coreswitch The directly connected interface is set to trunk, And release vlan10,20 ,30.
