I am trying to set up DHCP at some of our locations with a mix of "static" assignments and true DHCP assignments. We want some laptops to use the same IP address each time it is at that location, but other laptops we don't care what IP they have, just as long as they can connect.
I am going about this by configuring multiple "static" DHCP pools using client-identifier, and then one general pool that is just a subnet with no client-identifier.
The DHCP config is being done on a Cisco ISR 4321. The laptops connect by Wi-Fi to Meraki APs. The laptops are connected to a SSID on the APs which is configured to use an external DHCP server with L3 Roaming.
Part of the config I have set up:
ip dhcp excluded-address 10.228.AAA.1 10.228.AAA.29
ip dhcp excluded-address 10.228.AAA.96 10.228.AAA.254
ip dhcp pool GenPop
network 10.228.AAA.32 255.255.255.224
domain-name ourdomainname.com
default-router 10.228.AAA.1
dns-server 172.BBB.BBB.99 10.CCC.CCC.99
ip dhcp pool SN-5CD112TF3K
host 10.228.AAA.64 255.255.255.0
client-identifier MACADDRESS1
client-name CLIENT1
domain-name ourdomainname.com
default-router 10.228.AAA.1
dns-server 172.16.BBB.99 10.228.CCC.99
ip dhcp pool SN-5CG2140DD1
host 10.228.AAA.65 255.255.255.0
client-identifier MACADDRESS2
client-name CLIENT2
domain-name ourdomainname.com
default-router 10.228.AAA.1
dns-server 172.16.BBB.99 10.228.CCC.99
The problem I'm having is that the GenPop pool doesn't seem to want to hand out addresses.
If a laptop has a pool with a client-identifier, it pulls its assigned DHCP address just fine.
But if the laptop doesn't have a client-identifier - and then should use the GenPop pool - no address is assigned.
This doesn't make any sense to me, so I am obviously missing something simple.
Thanks for any suggestions you have.
