Introduction
Term Use in this Manual
Auto-VLAN This is a special, automatically-created and configured, radio port VLAN
(see radio port VLAN definition below) used by the zl switch to
automatically enable communication between a zl Module's downlink
port and a connected radio port.
Only one radio port
Auto-VLAN may exist on a zl switch.
The Auto-VLAN is special in that it is automatically created and
configured by the switch when a Module is installed into the switch, or
when a radio port is connected to a PoE-enabled zl switch port. However,
LLDP auto-provisioning must be enabled on the switch (it is enabled by
default).
When the switch creates the Auto-VLAN, it uses the first available
VLAN ID (VID) starting from the provisioned vlan-base value, which is
2100 by default. Therefore, the VLAN ID for the radio port VLAN is normally
2100.
After a radio port
Auto-VLAN has been established, no additional radio
port Auto-VLANs are created. The switch automatically configures this
VLAN by adding the downlink ports (<slot-ID>DP) of subsequently
installed zl Modules to this VLAN as tagged members. The uplink ports
(<slot-ID>UP) of the above Modules are automatically added as tagged
members to VLAN 1 (DEFAULT VLAN). When the switch detects LLDP data
at a port identifying a newly-attached radio port, it automatically adds
that port to the Auto-VLAN as an untagged member.
The lldp auto-provision radio-ports auto-vlan <vid> command may be
used to create or change the Auto-VLAN. See “Automatic RP VLAN
Operation Using LLDP” on page 12 for more details on auto-provisioning.
Downlink Radio
Ports
zl switch ports that share radio port VLAN membership (tagged or
untagged) with the Module's downlink port. If a radio port is directly
connected to the zl switch port, it must have an untagged membership in
the radio port VLAN.
Downlink Port The internal Module port that carries wireless station traffic to and from
the Wireless Edge Services zl Module. This port is identified by the switch
slot ID where the Module is installed, with ‘DP’ appended. For example,
“CDP” is the downlink port for a Wireless Edge Services zl Module
installed in slot C of a zl switch.
Infrastructure
switch
A switch that provides connectivity between a Wireless Services-
Enabled ProCurve zl Switch and a radio port. For management purposes,
these switches should also be members of a separate VLAN.
Infrastructure
switch port
A port in an intermediate switch that provides connectivity between a
Wireless Services-Enabled ProCurve zl Switch and a radio port. If the
radio port is connected directly to an infrastructure switch port, the port
must be an untagged member of the radio port VLAN. If not connected
directly to a radio port, the port may be a tagged or untagged member of
the radio port VLAN, depending on network requirements.
