FIGURE 9-19 VLAN Pool Configuration
A different DHCP pool must be created for each IP subnet for which DHCP
services should be provided. DHCP pools are not specifically tied to VLANs –
the DHCP server exists on every VLAN. When a DHCP request comes in, the
switch examines the origin of the request to determine if it should answer. If
the IP address of the VLAN matches a subnet for which the DHCP server is
configured, it will answer the request.
To add a new DHCP pool, click
Add. Fill in parameters as shown in the figure
below. Only those parameters shown are supported by the DHCP server. If
additional DHCP options are required, an external DHCP server should be
used. In the example shown, a DHCP pool has been created for network
10.26.1.0/24. The default router for the subnet is 10.26.1.1, and the primary
DNS server is 192.168.1.10.
