Configuration procedure
Before the configuration, make sure Switch A and Switch B can reach each other.
1. Configure Switch A:
# Configure interface VLAN-interface 100.
<SwitchA> system-view
[SwitchA] vlan 100
[SwitchA-vlan100] port Ten-GigabitEthernet 1/1/7
[SwitchA-vlan100] quit
[SwitchA] interface vlan-interface 100
[SwitchA-Vlan-interface100] ip address 10.1.1.1 255.255.255.0
[SwitchA-Vlan-interface100] quit
# Configure interface VLAN-interface 101.
[SwitchA] vlan 101
[SwitchA-vlan101] port Ten-GigabitEthernet 1/1/6
[SwitchA-vlan101] quit
[SwitchA] interface vlan-interface 101
[SwitchA-Vlan-interface101] ip address 1.1.1.1 255.255.255.0
[SwitchA-Vlan-interface101] quit
