You can configure a Cisco core switch as a DHCP server by creating DHCP pools, assigning default gateways, and ensuring VLANs and trunk links are properly set up. Step 1: Enable DHCP ServiceEnsure the DHCP service is enabled on the core switch. On most Cisco Layer 3 switches, DHCP is enabled by default, but you can verify with: CodeCopyshow running-config | include service dhcp If disabled, enable it with: CodeCopyservice dhcp Step 2: Create DHCP PoolsEnter global configuration mode and create DHCP pools for each VLAN: CodeCopySwitch# configure terminalSwitch(config)# ip dhcp excluded-address 192.

168. 1. 1 192.

168. 1. 10Switch(config)# ip dhcp pool VLAN10Switch(dhcp-config)# network 192.

168. 1. 0 255.

255. 255. 0Switch(dhcp-config)# default-router 192.

168. 1. 1Switch(dhcp-config)# dns-server 8.

8. 8. 8Switch(dhcp-config)# exit Repeat for other VLANs as needed.

Excluded addresses are reserved for static devices like routers or servers. Step 3: Configure VLAN Interfaces (SVIs)Assign IP addresses to VLAN interfaces on the core switch: CodeCopySwitch(config)# interface vlan 10Switch(config-if)# ip address 192. 168.

1. 1 255. 255.

255. 0Switch(config-if)# no shutdownSwitch(config-if)# exit Ensure each VLAN used by access switches has an SVI on the core switch. Step 4: Configure Trunk Links to Access SwitchesEnsure the links connecting the core switch to access switches are configured as trunks: CodeCopySwitch(config)# interface gigabitEthernet 1/0/1Switch(config-if)# switchport mode trunkSwitch(config-if)# switchport trunk encapsulation dot1qSwitch(config-if)# exit This allows multiple VLANs to pass between core and access switches.

Step 5: Verify DHCP ConfigurationCheck the DHCP bindings and active leases: CodeCopySwitch# show ip dhcp bindingSwitch# show running-config | section dhcp You can also enable debugging to troubleshoot: CodeCopySwitch# debug ip dhcp server eventsSwitch# debug ip dhcp server packet This helps confirm that clients are receiving IP addresses from the core switch. Step 6: Save ConfigurationFinally, save the configuration to ensure it persists after a reboot: CodeCopySwitch# copy running-config startup-config By following these steps, your core switch will act as a DHCP server, providing IP addresses to clients connected through access switches while maintaining proper VLAN segmentation and routing.
