DHCP reservation on Spark

[Alex-]

R81.10.10, centrally managed by R82, ClusterXL.

We have a network with DHCP set, let's say for illustration 10.10.10.0/24

DHCP is set from .190 to .250 for instance.

In that pool, we set a few reservations by creating an object: Single IP --> Name + IPv4 --> Exclude from DHCP --> Create DHCP reservation  and enter <MAC address> in the Spark WebUI.

When the reserved system reboots, we get a log entry in the System Logs like "No network for lease <reserved IPv4>" and it gets another IP in the pool. Another reserved system provides the same entry.

• The reservation is within the interface subnet and the DHCP pool
• Dynamic DHCP works normally

I don't seem to find any specific solution for this issue, if anyone has an advice or experience to share.

Hey Alex,

I did some research on this, but could not find much myself either. I would open TAC case and see what they say.

Solved, just a bit of tripping between existing leases and reservations, along with some client systems stubbornly insisting to keep their IP.

Good job!
