DHCP server does not
have enough IP
addresses.
Create a larger scope with more IP
addresses on the DHCP server.
DHCP server is acting
up and cannot assign IP
addresses for the
corresponding subnet,
even though there are
enough IP addresses.
For a Microsoft DHCP server, reboot the
server.
For the controller internal DHCP server,
disable DHCP and rebuild the scope.
L2 switch port is shut
down or not configured
properly.
Check the L2 switch, and ensure that the
port is not shut down. Ensure that this port
can access the DHCP server subnet (that
is, access the port for the same VLAN,
etc.).

DHCP server)
DHCP Option 125 or 43
(DHCP Option 130
-MITEL IP PHONE prior
to Release 4.0) is not
programmed up on the
second scope of the
DHCP server (or on the
second DHCP server).
OR
VLAN ID is not
assigned properly.
1. Identify if there is one DHCP server for
both VLANs, or if there is one DHCP
server per VLAN .
2. For one DHCP server for both VLANs,
ensure that
option 125/43 (option 130
prior to Release 4.0) is programmed in
the scope of Voice LAN as String type
with value of “MITEL IP PHONE”.
3. For one DHCP server per VLAN, ensure
that option 125/43 (option 130 prior to
Release 4.0) is defined in both DHCP
servers properly.
4. Verify that the vlan tag in the option 125
or 43 data string (option 132 prior to
Release 4.0) is set to assign to the
proper VLAN ID.
One DHCP server for
two VLANs network
configuration: IP helper
(sometimes called
DHCP Relay) address
on the router interface
is not set up correctly.
On the router interface (in which DHCP is
not residing), enter the IP helper address
and specify the IP address of the DHCP
server on the other side of the subnet (that
is, always set up IP helper address on the
DHCP client side).
Ensure the second scope is created for the
corresponding VLAN.
