Hi all,
I have two subnets (192.168.42.96/27 and 192.168.42.128/25) assigned to the same VLAN.
Is it possibile configuring a DHCP pool on a Cisco switch that can distribute IPs from more than one subnet?
Many thanks,
Maurizio

Generally no , but there is a mutiple DHCP subnet feature supported in 12.4T but i never seen it on dist or access switches or used it , not sure what its available on but you can cehck the doc below and follow the guides it may give more info on it

Hi Mark,
I have to implement VLANs segmentation on a LAN that actually is using a flat network (VLAN1 ).
I have to move the DHCP server to the Cisco 3650 and I would like to avoid the reassignment of IP addresses. So I'm trying to subnetting the actually addressing plan to satisfy our requirements.
For the server VLAN I need to reserve two subnet, 192.168.42.96/27 and 192.168.42.128/25. Some of the servers (and printers) have a reservation, others take an IP from the pool.

Hi Mark,
I think I will do so. Moving some of the clients or servers in ordero to obtain the segmentation that I want. So I will not need a dhcp pool with two subnets :)
