Configure DHCP To use DHCP persistence, you must first enable DHCP and set up the IP address
pool. Then you must assign a specific IP addresses to each port.
Set up the DHCP Server
To enable the DHCP Server mode on the switch, do the following.
1. From the Configure menu, choose DHCP.
2. Check the Enable DHCP checkbox.
3. To enable DHCP snooping, check the DHCP Snooping checkbox.
DHCP snooping restricts broadcast of DHCP requests beyond the
connected switch.This means that devices receive address assignments
from only the connected switch. This option is available only on VLAN
interfaces. To enable DHCP Snooping on a specific VLAN, check the
DHCP Snooping checkbox for the specific VLAN in the DHCP pool
table.
4. To reserve an address pool to only the devices that are specified in the
DHCP persistence table, check the Reserved Only checkbox in the
DHCP pool table.
DHCP requests from ports not in the persistence table or from another
device (switch) are ignored. By default, this option is disabled and the
Reserved Only checkbox is cleared.
5. Click Submit.
