HP A5830 Configuration Manual page 136

To enable Layer 3 communication among secondary VLANs associated with the same isolate-

user-VLAN, you must enable local proxy ARP on the upstream device (for example, Switch A in
Figure 41).
Associate the isolate-user-VLAN with the specified secondary VLANs.
3.
Step...
1. Enter system view
2. Create a VLAN and enter
VLAN view
3. Configure the VLAN as an
isolate-user-VLAN
4. Return to system view
5. Enter Ethernet interface view
6. Configure the link type of
the port
Access port
7. Assign port
to isolate-
Hybrid port
user-VLAN
8. Configure the isolate-user-
VLAN type of the port as
upstream
9. Return to system view
10. Create the isolate-user-
VLAN interface and enter
the isolate-user-VLAN
interface view
11. Configure an IP address for
the isolate-user-VLAN
interface

Required
By default, no isolate-user-VLAN type is
specified for the port
This configuration automatically assigns the
port to the secondary VLANs associated
with the isolate-user-VLAN
—

This configuration is required when
users in the isolate-user-VLAN must
communicate with other networks at
Layer 3

This configuration is optional when
users in the isolate-user-VLAN do not
need to communicate with other
networks at Layer 3
The vlan-interface-id parameter must take
the isolate-user-VLAN ID

This configuration is required when
users in the isolate-user-VLAN must
communicate with other networks at
Layer 3

This configuration is optional when
users in the isolate-user-VLAN do not
need to communicate with other
networks at Layer 3
By default, the isolate-user-VLAN ID is not
configured with any IP address
