<div>
yes you need to set the dhcp helper/relay address. <br />
<br />
If each vlan interface is taged with a ipaddress / subnet then the packets are forwarded to the DHCP server tag with this network information<br />
<br />
if the DHCP server has a scope that this information falls in then it will reply with a valid IP address.. <br />
<br />
the command is something like <br />
<br />
ip dhcp ? <br />
<br />
and of the top of my head i cant rwember the rest.. give me a few min<br />

<div class="content wysiwyg-content">
port 1: VLAN1, VLAN2, VLAN3<br />
Port2: VLAN5, VLAN6<br />
Port7: VLAN8<br />
<br />
i want to enable DHCP from switch, which has 8 IP ranges<br />
and each VLAN i want to assign different IP range<br />
is this possible from 3750 switch

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Network Management involves issues that are independent of specific hardware or software, including email policies, upgrade planning, backup scheduling and working with managed service providers for Desktop-As-A-Service (DaaS), Software-As-A-Service (SaaS) and the like through the use of tools, coupled with manufacturer standards, best practice guidelines, policies and procedures plus all other relevant documentation. Network management also includes monitoring, alerting and reporting, management reporting, planning for device or service updates, the backup of configurations, the setting of key performance indicators and measures (KPIs/KPMs), associated service level agreements and problem records as part of the IT Service Management (ITSM) framework.
