DHCP address pool with partial MAC not assigning to correct DHCP pool

[pilotboy72]

Hello,

I have created two DHCP address pools specifically for some of my IoT devices for monitoring purposes.  I have added the correct partial MAC addresses for each of the pools.

For the first address pool, all of the devices with the partial MAC address are correctly being assigned to that pool (where there is a single partial MAC).  The second pool has 4 partial MAC addresses specified in MAC access control (allow) and only a handful of the devices are correct assigned to that pool -- the rest are maintaining their addresses in the main pool.

Looking at the DHCP logs, I see requests from these devices for an "unknown" lease.  However, I don't see any response in logs for this.  This example is all I see:

dhcpd: DHCPREQUEST for 192.168.1.188 (192.168.1.1) from 00:07:a6:xx:xx:xx via igb1: unknown lease 192.168.1.188

The correct pool range for partial MAC 00:07:a6 should be 192.168.1.200 to 192.168.1.232.

Not sure where to go next to try to debug my config.  Any ideas?
