This section explains how to configure the DHCP and DNS server settings that
will enable users to access the network and the services that rely on domain
name resolution.
Configure DHCP Relay Settings
If your network includes a DHCP server, the TMS zl Module can provide DHCP
relay services to this server for endpoints in TMS VLANs. A DHCP server
serves only clients on the same subnet or VLAN. DHCP relay passes DHCP
requests from clients on one subnet to a DHCP server on a different subnet,
eliminating the need for a DHCP server on each local network segment. When
the module forwards the DHCP request, it uses its address on the VLAN
through which it contacts the server. For example, if the module reaches the
DHCP server through VLAN 40, the module will use its IP address on VLAN 40
in the DHCP request packet.
For the TMS zl Module to provide DHCP relay services on a VLAN, the VLAN
must have a static IP address rather than a DHCP address.
