4.9.3 Configuring Port Based HVLAN

4.9.3.1 Default Configuration

The default configuration for HVLANs is that there are no HVLANs configured, with TAGALL set to OFF and

all TPID values set to 0x8100.

4.9.3.2 Configuration Guidelines

The following rules are for setting the TAGALL and TPID values for a port-based HVLAN configuration:

• When adding a Network Interface to an HVLAN, the user should include FRAME=TAGGED

• When adding a Customer Interface to an HVLAN, the user should include FRAME=UNTAGGED

Note: Untagged is the default.

• On Customer interfaces, the port-based HVLAN tunnel is not operational until the interface is set to

tagall=on

• DHCP Relay/Snooping and IGMP Snooping must be disabled for the Customer Interface prior to setting the

interface to

tagall=on. Examples of the IGMP and DHCP commands are:

• Disable igmp interface=5.2

• Disable dhcp all interface=5.2

• An interface with a TPID value set can be a member of more than one HVLAN.

• An HVLAN can consist of one or more interfaces with TPIDs set at different values.

• When an interface is removed from an HVLAN, it will become a member of the an 802.1q default VLAN,

and the TPID value should be set back to the default 0x8100 value.
