Unanswered Question


We are a small ISP distributing internet access for our customers via vlan sub-interface. At this moment we plan suggest for customers service IPTV. For that purpose we create special vlan and set streamers and middleware in that vlan. On our switches(3750&2950&2960) configure MVR feature and can now access multicast stream from his own vlan. If customer use vlc all work fine. Problem begins when we try to use set-top-box. It use DHCP-client to recieve ip address. Is possible to define one DHCP ip-pool to assign addresses to all of such set-top-box ? What is strategy in this situation ? Is possible use one port of switch for both services ? Or simple give customers 2 ports with different services ?

Yes it is possible to setup the dhcp server config file to give out DHCP addresses based on the vendor class identifier (option vci 60). When the Discover come in from the STB it should have a string which identifies itself as a specific type/manufacture STB. USe a specific dhcp pool associated with the vci and only those STBs will get an address from that pool.
