1. Vlan benefits/functions
●Dividing broadcast domains
●Easy to manage
●Safe
1.1 Three elements of MAC address table:
●VlanID
●MAC address
●port number
The number of VLANs supported by Huawei is 1-4094
vlan: virtual local area network
untagged: A table from which the switch will release the specified label.
tagged: A list that is unconditionally released when certain specified VLANs (with tags) pass through the switch.
pvid: tag
2. The switch has different interface modes according to the connection object
1. Access access mode-computer: an interface can only be divided into one Vlan.
2. Trunk trunk link mode-switch: By default, only Vlan is allowed to pass other Vlan traffic and needs to be manually released.
3.hybrid mixed mode-computer/switch
2.1 Access：
Features: There is and can only belong to one Vlan.
交换机WS1：
[ws1]vlan bat 2 3
[ws1]int e0/0/1
[ws1-Ethernet0/0/1]port link-type access
[ws1-Ethernet0/0/1]port default vlan 2
[ws1]int e0/0/2
[ws1-Ethernet0/0/2]port link-type access
[ws1-Ethernet0/0/2]port default vlan 3
2.2 Trunk：
Features: It can carry the traffic of multiple VLANs.
