3550 + DHCP

[m.sir]

I have 3550 switch with four VLANs i would like to use this switch like DHCP server and I want create different DHCP pool for every VLAN...

Is it possible?? and how to do this???

You cannot use the Cat3550 as a DHCP Server. DHCP server can be implemented on routers only, not on switches.

Actually, the 3550s does operate as DHCP server in one specific situation, namely when running Express Setup...

Whether or not a 'switch' can be DHCP server, really depends on your definition of 'switch'. A Catalyst 6000 switch running Native IOS can be a DHCP server, and since the 3550 is the same code base, it might well do the same, had Cisco chosen to do so.

I don't know if this is going to help but I had the same problem. The only way I could get it to work was to use a Microsoft DHCP server with the different ip scopes matching the VLAN's and using the ip helper option on the switch which points the DHCP broadcast to the DHCP server on the different VLAN/IP address.
