Private Network

In IBP firmware version, it provides a feature similar to Cisco's PVLAN. It is called downlink
isolation. In general, the communication between all interfaces in the same port group is
possible. You could make an interface invisible for other member of this port group, and the
packets received on this interface will not be forwarded to the other member of this port group,
but the uplink ports. This chapter will describe how to configure the downlink isolation on the
Ethernet Connection Blade.
Beginning in privileged EXEC mode, follow these steps to configure downlink isolation for an
interface:
Command
Step 1 configure
Step 2 interface interface-id
Step 3 isolate
Step 4 exit
Step 5 show port-channel all
To add/remove the downlink isolation feature on an interface, use isolate/no isolate
interface configuration command. To display the downlink isolation setting, use show
interface status privileged EXEC command.
In this example, the interface 0/1, the member of the port group, is set to use downlink
isolation.
