Problems creating reserved IP address in a DHCP Pool
We created a pool of reserved DHCP IP addresses under an older firmware release (13.0.4.13). We've upgraded to 13.0.4.17 and are now trying to both update existing reservations and add new reservat...
Hi psda ,
Sorry about this issue, maybe there is a conflict somewhere else - can you edit your config file or do a show run like I do below, to show your static pools and your VLAN interfaces? Alternatively, please send your tech-support file (Diagnostics\Support Diagnostics to ProAVDesign@netgear.com) with a link to this post and one of our SEs will help you.
On my side, using the latest NETGEAR Engage Controller (www.netgear.com/engage) and creating a VAN 10 with your IP scheme, I can create plenty of static pools easily in Engage (Site Settings\VLAN Routing and DHCP Server\Advanced\DHCP Reservations):
interface vlan 1
routing
ip address 192.168.253.1 255.255.255.0
exit
interface vlan 10
routing
ip address 10.4.0.1 255.255.255.0
exit
ip management vlan 1 192.168.253.1 255.255.255.0
router rip
exit
service dhcp
ip dhcp excluded-address 192.168.253.1 192.168.253.9

I'm using the main UI and not the engage controller. I experimented with the engage controller and DHCP reservations but these only work if the controller is running and that isn't a viable scenario for our config.
What show option is dumping out the info you displayed above?
Can you do "show run" after "enable" so in global admin mode, and copy paste the end of the config here, like me, starting with the VLAN IP interfaces, and all the DHCP services under?
I emailed the info you requested to ProAVDesign@netgear.com
Note: the RDL entry is one that reports the error. However, all new ones that I create report it also.
All right, we'll take it from there!
Several problems below that we will address together with the ProAV Design team and you:
- Your IP schemes are Class C with 255.255.255.0 but so far with an exclusion spanning across different Class C subnets
- Client-identifier shouldn’t be used (it’s for other DHCP options, here we do MAC reservation)
- Default-router is needed to me, in the main dynamic pool to be bound to VLAN 160, and in any static pool for correct binding as well
