Displaying And Maintaining Isolation Groups; Port Isolation Configuration Example - H3C SR8800 Configuration Manual

Step
2. Enter interface view.
3. Configure the port as the
uplink port of an isolation
group.
NOTE:
An isolation group can have only one uplink port. The uplink port you configured for an isolation group
•
can overwrite the previous one, if any.
If you configure a common port in an isolation group as the common port of another isolation group, the
•
port leaves the previous group and joins the new one.
You cannot configure an isolated port in an isolation group as the uplink port in any isolation group.
•
You cannot configure the uplink port of an isolation group as an isolated or uplink port in any other
•
isolation group.
• You cannot configure a link aggregation member port as the uplink port of an isolation group neither
can you assign the uplink port of an isolation group to a link aggregation group.

Port isolation configuration example

Networking requirement
As shown in
Device is connected to an external networks through GigabitEthernet 3/1/4.
•
GigabitEthernet 3/1/1, GigabitEthernet 3/1/2, GigabitEthernet 3/1/3 and GigabitEthernet
•
3/1/4 belong to the same VLAN.

Command
•
Enter Ethernet interface view:
interface interface-type
interface-number
•
Enter Layer 2 aggregate
interface view:
interface
bridge-aggregation
interface-number
port-isolate uplink-port group

Remarks
Use either command.
•
The configuration in Ethernet
interface view applies only to the
port.
•
In Layer 2 aggregate interface
view, only the Layer 2 aggregate
interface is configured as the
uplink port of the specified
isolation group, and you can still
assign its member ports as
isolated ports. However, these
ports will be placed in Unselected
state and cannot receive or
forward data packets.
An isolation group has no uplink port
by default.
