Using zl Switch Features for the Module
If auto-provisioning is disabled when a Module is installed:
■ the switch adds the Module’s uplink port to the DEFAULT_VLAN as a
tagged member, and
■ the switch adds the Module’s downlink port, if not a member of any
existing VLAN, to the DEFAULT_VLAN as a tagged member.
This configuration will not support radio port adoption at Layer 2. Radio
port adoption at Layer 2 uses the downlink port. However, to prevent loops,
the Module will automatically ignore the downlink port’s membership to a
VLAN that also includes the uplink port.
When configuring radio port VLANs manually, you should:
■ first disable LLDP auto-provisioning (no lldp auto-provision radio-ports)
to ensure that radio ports are not automatically assigned to an
incorrect VLAN.
■ configure the Module’s uplink and downlink ports as tagged members
of separate VLANs.
Note Any non-radio port traffic received on the Module’s downlink port is dropped.
When manually configuring Module and radio port communication paths, you
must:
■ Specify a radio port VLAN using standard CLI commands, and add the
internal downlink port (as a tagged member) and downlink radio
ports, including infrastructure switches, to it.
■ Add the internal uplink port as a tagged member to any VLAN needed
for communication to the wired network.
■ Disable LLDP auto-provisioning and 802.1X RADIUS-assigned radio
port VLANs.
If you wish to specify the Auto-VLAN and not use the first available VLAN
starting from vlan-base (default VLAN 2100), but allow ports to be auto-
provisioned, do the following:
■ Use the lldp auto-provision radio-ports auto-vlan <vid> command to
enable and designate the desired Auto-VLAN.
■ Use LLDP auto-provisioning or 802.1X RADIUS-assigned radio port
VLANs for automatic downlink radio ports and Module uplink and
downlink port setup.
