How TO Configure DHCP

[Tompeshwar Lal]

we have 4 department Finance, Marketing, HR, contracts. All are in different subnet. We need to install a single DHCP server to provide IP for all subnets.

We have one Layer 3 switch Cisco WS-C6513-E; Windows server 2003 DHCP server.

How to design the network ?

how to create SVI  on switch????????

[Rolf Fischer]

Hi,

I assume they already exist.

A SVI ("Switch Virtual Interface") is the Layer-3 interfaces of a VLAN:

! L2-VLAN:

vlan 10

! SVI (L3)

interface vlan10

ip address x.x.x.x m.m.m.m

ip helper-address y.y.y.y (DHCP-Server)

From the client's perspective, the SVI's IP-address is the default-gateway.

More information about the DHCP realy-agent you can find here:

Hope that helps
