Solved: How to disable dhcp pool
1) I would like to know whether it is possible for the WS-C2960X-24TS-LL to do this (without any additional router / DHCP server), because I’ve been told Lan Lite does not support DHCP server feature. However, according to the Cisco Feature Search, C2960X with Lan Base software do support „DHCP – Server Port Based Address Allocation“. Clients connect to switch 2 and 3 using dhcp, switch 1 uses dhcp relay to forward requests from VLAN 2 to the dhcp server on VLAN 1. So far so good. Now I want switch 1 to add option 82 to the dhcp requests so the dhcp server can see whether the request came through switch 2 or switch 3. I tried turning on dhcp option 82 support on Solved: Hi Guys I have a cisco 1142 AP connected to a Cisco 2960 switch which is connected to a Fortinet Firewall that is the DHCP Server On the firewall I have configured 3 vLans and have 3 SSID’s on the cisco.

Hi Ameen, In General when you have multiple scopes for multiple subnets created in DHCP server then the ip helper-address will be one (DHCP server address). In your case you have created two subnets (primary & secondary) under one LAN interface and pointed ip helper-address to DHCP server. So if dhcp broadcast / unicast query send from any particular subnet

I want to be certain about ip dhcp snooping configuration on a Cisco 2960 switch (in Packet Tracer) Is it true that ip dhcp snooping will disable all dhcp traffic on all the switchports of a 2960 PacketTracer switch? So if that is true, enabling ip dhcp snooping trust on a switchport, will allow dhcp traffic for that switchport. Is my understanding of dhcp snooping right?

For example on port 14 we have a device Hi, on 2960 you cannot configure RACLs only PACLs ( only applied inbound) or mac ACLs to filter non-IP traffic so this wont work on your switch.

However, upon unboxing I can find no hint of dhcp service beyond acting as a relay. no ‚ip dhcp pool‘ command in the cli, no nothing! Because it will require that a DHCP server be physically located on each vlan. If there are 20 vlans do they want to deploy 20 DHCP servers? As Jon mentioned if the switch vlan interface has an IP address configured then it can also be configured with ip helper-address which will forward DHCP requests to a remote DHCP server.
