Independent Vlan Learning (Ivl) Support; Queue-In-Queue Vlan Support - Avaya 1000 Series Configuration Manual

VLAN Tagging
• To support multiple tagged routed VLANs on the Ethernet
- set the encapsulation type to dot1q for the interface
- set the encapsulation type to dot1q for each subinterface
• To support multinetting on the Ethernet
do not set dot1q encapsulation on the interface or any subinterface

Independent VLAN Learning (IVL) Support

Independent Vlan Learning allows the router to split the ARP table according to VLAN so that
the ARP table lookup is based on both MAC and VLAN Id. The default mode for ARP for
backward functionality is Shared VLAN learning mode.
When vlan forwarding and macbridging are enabled, to show whether IVL is set, issue the
show vlanfwd macbridge config command .
The following figure shows the output when IVL is enabled:
host/configure/vlanfwd > show vlanfwd macbridge config
Macbridge: Enabled
MacAge(in minutes): 5
MAC Learning Type: Independent VLAN learning (ivl)
The following figure shows the output when macbridge is disabled:
host/configure/vlanfwd > show vlanfwd macbridge config
Macbridge: Disabled
MacAge(in minutes): 5

Queue-in-Queue VLAN support

The Queue-in-Queue VLAN feature has backwards compatibility with previous commands and
there are no new CLI commands to support it.
In previous releases, Ethernet interfaces could be configured as Vlan Tagged or Vld Tagged
interfaces. When untagged packets were to be switched using a VLAN, the interface had to
be configured as Vlan Tagged. When a VLAN tagged packet was to be switched with another
level of VLAN, the interface had to be configured as Vld Tagged. The Vlan and Vld interfaces
had their own configuration and forwarding tables. Additionally, there was a limit of 2 levels of
Vlan tagging (Vlan + Vld) allowed.
Using the Queue-in-Queue VLAN feature, there is a single type of tagged interface which
allows packets to be switched with any number of VLAN tags. Packets are then switched on
the outermost level of VLAN tags. However, the VLAN for management can only accept single
tagged packets.
