# Create isolation group 1.
[SwitchA] port-isolate group 1
[SwitchA-port-isolate-group1] quit
# Assign ports GigabitEthernet 3/0/2 and GigabitEthernet 3/0/3 that connect to Switch B and
Switch C to isolation group 1.
[SwitchA] interface GigabitEthernet 3/0/2
[SwitchA-GigabitEthernet3/0/2] port-isolate enable group 1
[SwitchA-GigabitEthernet3/0/2] quit
[SwitchA] interface GigabitEthernet 3/0/3
[SwitchA-GigabitEthernet3/0/3] port-isolate enable group 1
[SwitchA-GigabitEthernet3/0/3] quit
# Configure VLAN 3 as a community VLAN in isolation group 1.
[SwitchA] port-isolate group 1

[SwitchA-port-isolate-group1] quit
2. Configuring Switch B:
# Create VLAN 2 and VLAN 3, assign GigabitEthernet 2/0/2 to VLAN 2, and assign
GigabitEthernet 2/0/3 to VLAN 3.
<SwitchB> system-view
[SwitchB] vlan 2
[SwitchB-vlan2] port GigabitEthernet 2/0/2
[SwitchB-vlan2] vlan 3
[SwitchB-vlan3] port GigabitEthernet 2/0/3
[SwitchB-vlan3] quit
# Configure GigabitEthernet 2/0/1 as a trunk port and assign the port to VLAN 2 and VLAN 3.
[SwitchB] interface GigabitEthernet 2/0/1
[SwitchB-GigabitEthernet2/0/1] port link-type trunk
[SwitchB-GigabitEthernet2/0/1] port trunk permit vlan 2 3
3. Configure Switch C in the same way Switch B is configured.
Verifying the configuration
# Display information about isolation group 1 on Switch A.
[SwitchA] display port-isolate group 1
Port-isolate group information:
Uplink port support: NO
Group ID: 1
Group members:
GigabitEthernet3/0/2 GigabitEthernet3/0/3
The output shows that ports GigabitEthernet 3/0/2 and GigabitEthernet 3/0/3 are assigned to
isolation group 1.
# Display the configuration of isolation group 1.
[SwitchA] port-isolate group 1
