Configuring Vlan Based Hvlan - Allied Telesis SwitchBlade x3100 Series Manual

Introduction
4.9.4.2 HVLAN Support for the SBx3112 Interfaces
The SBx3112 can support HVLAN on either the GE24 or XE4 cards, since either card can support network
interfaces.
The x3112 does not allow Tagged-only frame acceptance on an interface that is a member of a customer VLAN
(CVLAN)/ tunneled VLAN. This means that if an interface is an untagged member of a VLAN from which the
interface is being deleted and the interface is a member (tagged and untagged) of customer VLAN (CVLAN),
the interface delete is not allowed and an error message is generated.
For example, this shows the rejection of an attempt to delete the default untagged vlan on an interface that has
been associated with a CVLAN:
officer SEC>> CREATE HVLAN VID 300 TYPE VLANTUNNEL
Info (040590): Successfully created HVLAN(s) 300
officer SEC>> CREATE VLAN VID 20
Info (040590): Successfully created VLAN(s) 20
officer SEC>> HVLAN 300 INT 0.0 FR TAGGED
Processing.....
Info (040604): Successfully added HVLAN(s) 300 on interface(s) ETH:[0.0]
officer SEC>> ADD VLAN 20 INT 1.0 FRAME TAGGED
Processing.....
Info (040604): Successfully added VLAN(s) 20 on interface(s) ETH:[1.0]
officer SEC>> ADD VLANTUNNELMAP VLAN 20 HVLAN 300
Info (040556): 1 VLANs were added to the tunnel for HVLAN 300
officer SEC>> DEL VLAN 1 INT 1.0
Processing.....
Error (040617): Interface(s) ETH:[1.0] can not deleted from VLAN(s) 1
Because interface(s) acceptable frame type would become
VLAN-tagged only.

4.9.5 Configuring VLAN Based HVLAN

4.9.5.1 Default Configuration
When the SBx3112 is initially booted up (or from a "Purge database"), all interfaces will be configured to be the
default VLAN (VID 1), and no HVLAN is created by default.
4.9.5.2 Configuration Guidelines
When adding a Network Interface to an HVLAN, it should be provisioned with FRAME=TAGGED (exam-
•
ple "add hvlan Btunnel interface=10.0 frame=tagged")
