Cisco Aironet 2600 Series DHCP Server Configuration NOT Serving Addresses?
I have (2) AIR-SAP2602I-A-K9 similarly configured,
on two different isolated LANs.
They don't appear to be handing out addresses via DHCP.
{If I connect them to a LAN with a different DHCP server,
the wireless devices can get addresses
from that other DHCP server on the LAN, through the AP.}
I followed 12.4.25d.JA.cg.pdf

Solved! Go to Solution.
Thats the DHCP Pool range 192.168.29.88 through 192.168.28.95
Well that's going to confuse your clients.
And that's NOT how you configure your "range". See below:
ip dhcp excluded-address 192.168.29.1 192.168.29.87
ip dhcp excluded-address 192.168.29.96 192.168.29.254
ip dhcp pool RCS1
network 192.168.28.211 255.255.254.0
default-router 192.168.28.1
lease 0 1
ip dhcp pool RCS1
network 192.168.29.88 255.255.255.248default-router 192.168.28.1
lease 0 1
The subnet is different.
Your network is 192.168.29.88 up to 192.168.29.95 but your default router is way out.
The LAN address range is 192.168.28.0 through 192.168.29.255 (/23)
The AP is assigned IP 192.168.28.211 with mask 255.255.254.0 (/23)
Thats the DHCP Pool range 192.168.29.88 through 192.168.28.95
{Unless I am misunderstanding the documentation 12.4.25d.JA.cg.pdf}
...
Step 3 ip dhcp pool pool_name Create a name for the pool of IP addresses that the wireless device assigns
in response to DHCP requests, and enter DHCP configuration mode.
Step 4 network subnet_number
[ mask | prefix-length ]
Assign the subnet number for the address pool. The wireless device
assigns IP addresses within this subnet.
Thats the DHCP Pool range 192.168.29.88 through 192.168.28.95
Well that's going to confuse your clients.
And that's NOT how you configure your "range". See below:
ip dhcp excluded-address 192.168.29.1 192.168.29.87
ip dhcp excluded-address 192.168.29.96 192.168.29.254
ip dhcp pool RCS1
network 192.168.28.211 255.255.254.0
default-router 192.168.28.1
lease 0 1
Yes, of course, you're right.
However It doesn't appear to allow redefining the ip dhcp pool network,
and I can't seem to find a command that willl clear / remove the pool?

The answer is: default ip dhcp pool RCS2
(sigh)

Sorry, just saw your post.
Try this:
no ip dhcp pool RCS1
ip dhcp pool RCS1
network 192.168.28.211 255.255.254.0
default-router 192.168.28.1
lease 0 1
