i have 6500 & have about 32 Vlan for voice & data
to each vlan there are DHCP pool & it knows the range from interface vlan & each vlan have its default router
NOW i need to add FWSM to protect the data so i need to remove Interface Vlans from the switch to FWSM
so i wonder how the DHCP pool will know the respective VLAN
is there are any configuration or it will know it from FWSM or it won't be recommended to use DHCP server on switch in this case

Hi
If i understand correctly you need the FWSM to forward on DHCP requests from clients attached to it's interfaces.
If i have understood you can do this as the FWSM has a DHCP relay feature although there are a number of caveats to it's use. Attached is a link to a doc with details on this feature

Hope i have understood
