Magical Effect DHCP relay service agent for a number of VLAN

Work in the LAN environment, the management of hundreds of workstations IP address is not a simple issue, in order to effectively address this problem, many LAN administrators will use in LAN set up a DHCP server approach to automatically ordinary workstations Allocation of IP addresses, so the network can be dismissed from the management manual for the workstation IP address assigned to repeat the operation, which has effectively improved the local area network management efficiency. But in the actual network maintenance may be encountered in the course of this phenomenon, that is, when the LAN installation configuration of the three switches, according to the different departments of a number of workstations are a few of VLAN, all in the LAN At the same time will not be able to workstations from the same DHCP server where the effective application of IP addresses, which is unable to work because of a DHCP server in a number of VLAN, in other words, ordinary LAN workstations address the issue of the request for information is not in a number of Vlan in the broadcast, when ordinary workstations located in different VLAN in, the address of the request for information on the absence of accurate and sent to find common workstation failure. Then how can we effectively address this difficult issue is «the simplest way, is nothing more than a Vlan set up a separate DHCP server, but the efficiency of this operation is often very low, but is not conducive to the reunification of network management and maintenance, This method of SBCSAM Smart Business Communication Systems for Account Managers operation is relatively low. In fact, installation, configuration of the three-tier local area network switches in the work environment, we can configure the switch three relay agent parameters, to achieve the same DHCP server to service more than Vlan the Cisco Certification purpose!
