Is this something recommended in my case? 1) I want to replace Cisco routing “DHCP Pools” in favor of a true DHCP Server. My problems are, in our environment, we primarily use VLANs and IP ranges within each Vlan for traffic reasons. We have network probes that require the use of an IP range per probe for test purposes. a. See example below. b. We have 500 Vlans in our test environment and require Vlans 500-999, each with its own IP range.

I’d like to add DHCP Pools and/or IP Ranges per subinterface. Is this something recommended in my case?

1) I want to replace Cisco routing “DHCP Pools” in favor of a true DHCP Server. My problems are, in our environment, we primarily use VLANs and IP ranges within each Vlan for traffic reasons. We have network probes that require the use of an IP range per probe for test purposes.

a. See example below.

b. We have 500 Vlans in our test environment and require Vlans 500-999, each with its own IP range.

Cisco 7206 Config:
ip dhcp pool vlan500
network 10.115.50.0 255.255.255.240
dns-server 10.15.12.9 10.10.1.10
default-router 10.115.50.1
domain-name dvlab.acterna.com
lease 10
!
interface GigabitEthernet5/0.500
encapsulation dot1Q 500
ip address 10.115.50.1 255.255.255.240
ip access-group 100 in
ip nat inside
no cdp enable

Probe Vlan and IP ranges

Vlan GW Start End Mask

500 10.115.50.1 10.115.50.2 10.115.50.14 255.255.255.240

501 10.115.50.17 10.115.50.18 10.115.50.30 255.255.255.240
