DHCP Discovery

(VLAN) (after
releasing the first IP
from the native
DHCP server) The 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.
The L2 switch port for
the phone interface is
shut down or not
configured properly. Check the L2 switch and ensure that the
port is not shut down.
For a Cisco L2 switch, ensure that this is a
trunk port with Dot1q encapsulation, and
that this trunk port allows both native and
Voice LAN to pass through.
For an HP L2 switch, ensure that Native
Lan is untagged, and that Voice LAN is
tagged
The L2 switch port for
the router interface is
shut down or not
configured properly. Identify if there are two physical interfaces
to the router (one per VLAN), or a router on
a stick configuration (one physical with
virtual sub- interfaces).
Ensure that the port(s) on both sides (L2
switch and router) are not shut down.
If there is a physical interface on the router
for each VLAN, make sure that the L2
switch is set to access port for the
corresponding VLAN/ subnet correctly. OR
If there is one physical interface on the
router for multiple VLANs, ensure that this
is a trunk port on the L2 switch, and ensure
that this trunk port allows both native and
voice LAN to pass through.
On the router subinterface, ensure that the
proper VLAN is associated to the remote
subinterface.
The DHCP server does
not have enough IP
addresses. Create a larger scope with more IP
addresses on the DHCP server.
