Installation and Operation Manual
Avaya IP-DECT Base Station & IP-DECT Gateway version 7.2.x
If the server rejects the lease using a NAK, the client will forget about the lease and continue to
operate like it does for the first boot.
First boot with VLAN ID option received
If an offered lease includes the VLAN-ID option and the ID proposed differs from the VLAN
ID the devices currently operates with (that is, from the id configured in the devices
configuration), the device will change its VLAN ID to the one received in the VLAN-ID option.
It will not request the lease though. Instead, it will continue to send DISCOVER requests on the
new VLAN ID. If a lease is obtained there, all lease information is stored in the config file as
usual.
You can disable the VLAN-ID processing using the /no-vlan option.
Reboot with VLAN ID
If the device finds lease information in the config file at boot time and if there is a VLAN ID
different from the devices current VLAN-ID, it will re-configure itself to the new VLAN ID and
try to request the saved lease as usual. If the lease is rejected with a NAK by the server, the
device will re-configure itself to the pre-configured VLAN ID and try to DISCOVER a new
lease as usual.
E.7 VLAN set with LLDP
From version 7.1.X, VLAN is also set with LLDP if provided by the switch. See
VLAN on page 93.
E.8 Changing Configuration Options set by DHCP Options
If a device has been configured by DHCP, those parameters cannot be changed. Any attempt to
do so will issue a "Reset required" message.
