Thank you yes that is the what we are looking to do. Been working with AirOS so need to jump on IOS-XE. I agree AirOS won't go away completely for a few more years.

Thanks so much Scott I think we have 3702's and 2802's as well already. Haven't worked with a 4802 yet. For AirOS we have 2 x 5508's and 2 x 2504's. 3504 is the next step up from 2504 as far as I know correct?

Thank you for that link. Yeah 9800 with eWLC 9300 doesn't make sense.

Thanks Rasika so this is more like for a work related lab so 9800-L shouldn't be an issue. Is there any specific benefit of 9800-40 over -L? If it is justifiable it may get approved but I'm not seeing any major differences when it comes to features. Hope you are doing well and staying safe. Ali

Looking to upgrade some lab gear from 5508's/2504's and 2600's 2700's and wanted to get some opinions: C9300-24P (It says 200 APs, so I'm guessing that is 200 per stack? All the AP's need to be connected to the same stack? Or is this different from the 3800 serious?) Catalyst 9800-L Catalyst 9800-40 (I think this may be an overkill as 9800-L should be able to do everything this one does other than the AP, client count and throughput) For APs I was thinking 2 x 9120 2 x 9130 Thank you

I know this is old and you may have figured this out already but you have to make sure that on the secondary and tertiary you have run the same commands for the Flexconnect groups also: config flexconnect group group-name ap add ap-mac

Thanks Andrew that is correct it is a /30 P2P link. There is nothing on 10.20.8.0/24 and 10.20.7.0/24 have static IP's only no DHCP. Only BAD_ADDRESS messages are on 10.21.x.x/16 range. I did notice that none of the interfaces have "no ip proxy-arp" command and I am looking to add that on both ends later tonight. Yes I concur its a terrible design and I would love to fix it/change it. I have talked to the customer about it as well, but they have to make the last call.

Thanks Andrew please see my responses below: 1st issue - secondary IPv4 addressing and DHCP... You need to create three scopes for each of the networks and then combine them into a Super Scope on the DHCP servers so they know they can issue addresses from any of the subnets when they receive DHCP requests forwarded by the routers primary IPv4 address. *** No DHCP is needed for the secondary IP's. Devices in those networks are setup with Static IPs. DHCP is only needed for the 10.21.0.0/16 network 2nd issue - DHCP resilience. Three options here. Cluster (MS Clustering with a VIP so both DHCP servers need to be on the same L2 network), DHCP failover (available from 2012 R2 where the DHCP server database is replicated so each server knows what has been leased) or split the scopes so the servers don't have overlapping addresses to dish out. *** DHCP servers are setup with option 2 i.e; DHCP Failover. There are two scopes on the servers: 10.20.0.0/16 10.21.0.0/16

Don't see the MAC in the scope that is what I have been trying to find out but no luck so far. I have asked customer to send me the logs lets see will keep y'all posted.

Thank you for the reply, please see below: DHCP servers are setup with the fail over configuration so only one is supposed to respond unless the primary goes down only then the secondary is supposed to respond. I talked to multiple systems engineers and they confirmed this behavior, unless I'm missing something please do let me know. We do not need DHCP to assign IP's for the secondary subnet, there is no issue with the assignment, issue is that one of the scope is getting filled with "BAD_ADDRESS". Like shown here. https://www.petenetlive.com/KB/Article/0001651 10.21.0.0/16 network is getting IP's but it fills up with these BAD_ADDRESS IP's so customer has to keep cleaning them up.

Secondary are static only. DHCP is only for the 10.21.0.0/16 network.

Yes checked with the customer couple of times and he said that it is enabled. Logs show the MAC? I don't think there are any MAC's in the MS Windows DHCP logs.
