port-isolate enable
Syntax
port-isolate enable
undo port-isolate enable
View
Ethernet interface view, Layer-2 aggregate interface view, port group view
Default Level
2: System level
Parameters
group group-number: Specifies the ID of the group to which the ports are to be added. The value range
varies with devices.
Description
Use the port-isolate enable command to add a port in Ethernet interface view or a group of ports in
port group view to an isolation group as isolated ports.
Use the undo port-isolate enable command to remove the port or ports from the isolation group.
In Ethernet interface view, the configuration applies to the current port.
In port group view, the configuration applies to all ports in the port group.
In Layer-2 aggregate interface view, the configuration applies to the Layer-2 aggregate interface
and all its member ports. After you make the configuration, the system starts applying the
configuration to the aggregate interface and its aggregation member ports. If the system fails to do
that on the aggregate interface, it stops applying the configuration to the aggregation member ports.
If it fails to do that on an aggregation member port, it simply skips the port and moves to the next
port. For detailed information about Layer-2 aggregate interfaces, refer to Link Aggregation
Configuration in the Access Volume.
Note that: This command adds a port to the default isolation group (isolation group 1).
Examples
# Assign ports Ethernet 2/0/1 to the isolation group.
<Sysname> system-view
[Sysname] interface ethernet 2/0/1
[Sysname-Ethernet2/0/1] port-isolate enable
# Assign all the ports within port group aa to the isolation group.
<Sysname> system-view
[Sysname] port-group manual aa
[Sysname-port-group-manual-aa] group-member ethernet 2/0/2
[Sysname-port-group-manual-aa] group-member ethernet 2/0/3
[Sysname-port-group-manual-aa] group-member ethernet 2/0/4
[Sysname-port-group-manual-aa] port-isolate enable
# Assign Layer-2 aggregate interface Bridge-aggregation 1 and its member ports to the isolation
group.
