Configuring Port Isolation

Configuring Port Isolation

Configuring a Port Isolation Group

# Configure port isolation on GE1/0/1 and GE1/0/2 to implement Layer 2 isolation and Layer 3 interworking on the two interfaces.
<HUAWEI> system-view
[HUAWEI] port-isolate mode l2
[HUAWEI] interface gigabitethernet 1/0/1
[HUAWEI-GigabitEthernet1/0/1] port-isolate enable group 1
[HUAWEI-GigabitEthernet1/0/1] quit
[HUAWEI] interface gigabitethernet 1/0/2
[HUAWEI-GigabitEthernet1/0/2] port-isolate enable group 1
[HUAWEI-GigabitEthernet1/0/2] quit
# Configure port isolation on GE1/0/10 to GE1/0/20 to implement Layer 2 and Layer 3 isolation on these interfaces.
<HUAWEI> system-view
[HUAWEI] port-isolate mode all
[HUAWEI] port-group portgroup1
[HUAWEI-port-group-portgroup1] group-member gigabitethernet 1/0/10 to gigabitethernet 1/0/20
[HUAWEI-port-group-portgroup1] port-isolate enable group 2
NOTE:
All S series chassis switches support Layer 2 and Layer 3 isolation. S series box switches support Layer 2 and Layer 3 isolation excluding the S2700SI and S2700EI running V100R006C05 and the S1720GFR, S1720GW, S1720GWR, S1720X, S1720GW-E, S1720GWR-E, S1720X-E, S2720EI, S2750EI, S5700LI, S5720LI, S6720LI, S6720S-LI, S5710-X-LI, S5710-C-LI, S5700S-LI, and S5720S-LI running V200R001 and later versions.

Configuring Unidirectional Isolation

# Configure unidirectional isolation to isolate GE1/0/5 from GE1/0/6, GE1/0/7, and GE1/0/8 unidirectionally. This configuration ensures that Layer 2 data packets from GE1/0/5 cannot reach GE1/0/6, GE1/0/7, and GE1/0/8.
<HUAWEI> system-view
[HUAWEI] port-isolate mode l2
[HUAWEI] interface gigabitethernet 1/0/5
[HUAWEI-GigabitEthernet1/0/5] am isolate gigabitethernet 1/0/6 to 1/0/8
