BOOTP/DHCP Relay
Page 26-8
Because the clients in group 3 are not on the same segment as the
DHCP
server, they must
request an
IP
address via the
BOOTP
relay routing entity in the switch. When a
DHCP
request
frame is received by the
BOOTP
relay entity, it will be forwarded from group 3 to group 2. All
the
DHCP
-ready clients in group 3 must be members of the same
VLAN
, and the switch must
have the
BOOTP
relay function configured.
Example 2
This application example has a single group in a network with a mix of
DHCP
-ready and non-
DHCP
clients.
DHCP
-ready and non-
DHCP
clients can coexist in the same network, group, or
segment. There are two types of AutoTracker policies defined within the group—IP address
and IP protocol.
AutoTracker IP Policy Places DHCP Clients in Same VLAN
Whenever AutoTracker receives an
IP
frame, it examines the frame for an
IP
network layer
policy match. In the case of
DHCP
, the client generates an IP frame without an IP address.
Without an IP address, AutoTracker will not be able to place the client into a
VLAN
based on
IP address. Therefore, the client will become a member of the
VLAN
defined by a general IP
Protocol policy (i.e.,
VLAN 30
).
