Huijue core switch disables DHCP
To disable DHCP on a Huijue core switch, you need to remove or deactivate any DHCP pools and ensure VLAN interfaces are not configured to provide IP addresses.
Steps to Disable DHCP
- Access the Switch CLI
- Connect via console, SSH, or Telnet.
- Enter system view mode:
system-view
- Check Existing DHCP Configuration
- Display all DHCP pools:
display dhcp server ip-in-usedisplay dhcp server pool - This helps identify which pools are active and which VLAN interfaces are associated with DHCP.
- Display all DHCP pools:
- Remove DHCP Pools
- Enter the DHCP view and delete the pools:
dhcp serverundo pool <pool-name> - Repeat for all configured pools to stop the switch from assigning IP addresses.
- Enter the DHCP view and delete the pools:
- Disable DHCP on VLAN Interfaces
- Enter the interface view for each VLAN interface:
interface Vlanif <vlan-id>undo dhcp select global - This ensures the interface no longer provides DHCP services to connected clients.
- Enter the interface view for each VLAN interface:
- Save Configuration
- After making changes, save the configuration to prevent DHCP from reactivating after a reboot:
save
- After making changes, save the configuration to prevent DHCP from reactivating after a reboot:
Verification
- Confirm that no DHCP pools exist:
display dhcp server pool - Check that VLAN interfaces are no longer issuing IP addresses:
display interface Vlanif <vlan-id>
Notes
- Disabling DHCP on a core switch is recommended when a dedicated DHCP server exists to avoid IP conflicts.
- If the switch previously acted as a DHCP relay, ensure that relay configurations are also removed to prevent forwarding DHCP requests. By following these steps, the Huijue core switch will no longer function as a DHCP server, and all IP address assignments will need to be handled by an external DHCP server or manually configured static IPs ( ).
