Wireless LAN Controller or WLSE?

As I'm struggling with a 2504 WLC right now, and have successfully deployed and maintain SME networks with up to a dozen or so autonomous AP's I have to ask, what does the WLC bring to the table when the max number of AP's is, lets say less than 30? I want to ignore batch configuration for now. I have plenty of copy 'n' paste templates so configging a dozen or so AP's doesn't take long and I still have to set up the WLC which also takes time so initially time saved is not going to be much when using a WLC. So what am I missing? Where's the big advantage of a WLC? Is there one, or is it simply Cisco creating demand out of thin air?

Scratch that. I see the WLSE is EoL with no replacement offered. Back to the 2504 I go...

Simplified management, automatic channel selection, automatic tx power management, rogue AP detection/suppression, seamless roaming (huge for voice deployments)

Pretty much what Paulg See Profile said. But, if you only have a handful of APs with one or two SSIDs and no wireless voice, then you're right, there's really not a huge benefit.

What problems are you having with the 2504?

2nd Paulg See Profile and Delco24 See Profile : it's a question better answered if you have multiple APs to push out for deployment and mangement.

It's my first one, so lots!
Right now the wireless phones can connect to the AP's but they aren't getting a DHCP response.
DHCP scopes are on a 2960S switch and all other hosts tested on the Voice VLAN receive DHCP responses as expected. That's 1...
Trunks are set up, mls qos and CoS / DSCP trust points are set but CoS to DSCP mappings are not BUT this is a pre-deployment lab. I'll get to those shortly.

2. I have set the CME router (a 2901) to auto-reg-ephone so I am assuming that once the phones get an IP address, CME will see them. I am perfectly OK setting ip wired phones, DN's etc etc, it's the wireless that's kickin' my *** right now.

Try Disabling DHCP proxy...under Controller > Advanced
Does the phone have any IP address?

DHCP proxy is currently disabled but I have tried it enabled as well.
I have two 7925 wireless phones. One is set up for DHCP, one is set up with a static IP and DNS, DHCP Server and TFTP server.
The CME router is set for auto-reg-ephone and I have manually added the phone that I manually configured which seemed to make sense. But neither phone will join the CME. Wired phones are found no problem.
I have noticed that I can't ping the DHCP SVI IP address from the WLC.
WLC Management ip is 192.168.0.5/24 and is VLAN 1
Phone VLAN is 192.168.50.0/24, SVI is 192.168.50.2, CME sub-if is 192.168.50.1. The 2960S is the DHCP server.
I can ping anything on VLAN 1 from the WLC but nothing else.
Appropriate DHCP scopes are set and include Option 150, Import all and DNS server IP's as appropriate.

Have you permitted your phone vlan on the trunk to the 2504? All vlan's used by the wlc need to be on the trunk port (or LAG) going to the wlc. Once that's done you need to create interfaces on the wlc for the appropriate vlans (same spot as you define the ap manager interface).

That may be where I'm going wrong.
The WLC has 4 VLANS each with it's own appropriate interface. The un-tagged VLAN is the management VLAN and is in the native VLAN subnet hanging off port 1 which is a trunk to the switch. All VLAN's are permitted on the switch trunk port. The 2504 does not seem to support LAG.
Each WLAN seems to have to be "mapped" to it's own interface which the WLC creates and names the same as the WLAN. If I put the Voice WLAN into the Management Interface the native VLAN seems to be bumped off as if I had changed the native VLAN. Very confused...

The 2504 can support LAG if you upgrade to 7.4 (released last week).

So... ok. First you create the interfaces which is where you associate the IP address to a vlan. When you create the WLAN your associate the WLAN to an interface. So when you create the WLAN make sure you select the appropriate interface (ap management interface is default). So when you create your voice WLAN, select your voice interface from the drop down menu. Have you tried this or am I misunderstanding the problem?

Got the 2960S config (minus passwords and other sensitive info) for review?

And if I read this right, you confirmed the pool itself is functional and is handing out DHCP addresses
as expected right? I've never worked with wireless phones but I'm halfway wondering if there's certain
DHCP options that are(n't) being set.

@ Phantasm
Yes I have done all that acording to what you say, as far as I can tell. I will put up screenshots later.

Hellfire, I will put up the config but as it's a pre deploymant lab there isn't much:

=========================================

vlan 50

ip dhcp-pool Voice
network 192.168.50.0 255.255.255.0
option 150
import all
dns 192.168.0.1 8.8.8.8 8.8.4.4
defualt router 192.168.50.2

ip dhcp excluded-address 192.168.50.1 192.168.50.99

Int vlan 50
ip address 192.168.50.2 255.255.255.0

Int Gig 1/0/47
description Link to WLC
swi mo trunk

Int Gig 1/048
description Link to CME
swi mo trunk

==========================================

The CME is a 2901. There are 4 or 5 sub-ifs on Gig 0/0 which relate to the VLAN's on the switch and all SVI's and sub-ifs are pingable from everywhere.

int gig 0/0.50
ip address 192.168.50.1 255.255.255.0

The router is brand new so it's running CME 8.5 (I think) so it's pretty much the latest version.

CME will see and discover every wired phone I throw at it and I am OK with adding DN's and assigning buttons etc.
I put my laptop wirelessly on to the Voice network to test. It received a DHCP address and could ping throgh to the CME and the WLC.
I cannot ping from the WLC CLI to any subnet other than the native vlan which is VLAN 1, 192.168.0.0/24

I checked my dhcp server and I'm handing out option 66 to my wireless phones which points to our call manager. Not sure if that'll help. The switch config looks fine to me.

I'll give option 66 a go when I get back to my lab this evening, and I'll report back.

Option 66 produced no results. I removed Option 150 before adding Option 66 and I pointed it at the CME.
On the phone wiith static configs I see these system messages in this order from phone boot:
IP Initialized
TFTP Timeout
Installed MIDP Module Successfully
CiscoCM1
DNS Unknown Host

----------------------------------------------------------------

Delco, even with the no ap option the output is still huge. Care to narrow it down a bit so I can show the relevant sections?

================================================

I included the native VLAN and the Voice VLAN. Phones are on 802.11a, native VLAN is 802.11n.

EDIT.
Just noticed the active physcal port for Voice is port 2. No idea how that happened! I've plugged port two into the switch but no joy.
Going to see if I can put voice back on port 1.

OK, voice is back on Port 1... just re-booting everything just in case!

Edit...
Still nothing

Second edit...
Both phones now have matching system messages, so I guess that's progress of sorts. I just don't know where that progress is taking me!

Third edit...
The DHCP phone is now showing an xml.default.cnf.xml: TFTP error message.
Schoolboy error alert! Am I supposed to be offering the .cnf file out from TFTP on the CME?
If so, I don't have it. Can I download it from Cisco.com?

Fourt edit...

The .cnf files are present for the statically configured phone.
sho telephony-service tftp-binding shows what's there, so I don't think it's a TFTP issue unless it's related to a DHCP option or an IP address issue.

I should've elaborated. We use option 66 to allow the phone to pull the config file from cme via tftp. I am not sure where you get the file... I would have to check with our voice guy but I'm not in the office.

Cracked it! Not quite sure which config got it working but I suspect it was adding the TFTP server (the CME) IP address to the handsets under the network config setting. I added the native VLAN ip address of the CME as a secondary TFTP Server address and both phones popped up on the CME really quickly. One DN and one ephone mac-address later and I had wireless calls between the two handsets. I will brick one of the handsets tomorrow to pin down exactly what was needed to get it working.

Now I can at least show the project manager that we can route calls. Imagine how pleased he will be when I tell him I have a phone system on which telephone calls can be placed and received...

I'd than to thank you guys for replying to my plea for help. It really is very much appreciated. I will no doubt be back with more questions as I get deeper in to the whole CME / wireless phone set up. But now it's time for a celebratory cup of tea!

The Voice pool DNS server should be the CME host only (50.1?) so it can find CiscoCM1 (the call manager.) There's no reason for them to resolve public internet hosts; and the router can do it if they do. [Note: that's actually 'CiscoCM1.' -- NO DOMAIN component. That makes it hard to add to most DNS servers.]

You can get around this by static programming *everything* on the phone. (that's the way I make remote 12sp+'s run. Yes, I still have one.) I'm sure your installation is too large for that. Option 150 (ip addresses) or 66 (hostname or address) points to CME to get their configuration file(s). DNS is how they'll find the callmanager.

[edit]
That would be...

ip dhcp-pool Voice
network 192.168.50.0 255.255.255.0
option 150 ip 192.168.50.1

Ok, thanks for that. It is currently working with import all but I'll remove it and I'll ditch the Google DNS too.
Also Option 66 is currently configured, pointing at 50.1 but I'll try Option 150 again to see what happens and so I can properly document the process and config required.

The install isn't that big. 12 wireless phones, about 12 wired but only 2 of them are "feature phones" (7940G's). The rest are 6901's. There are 8 1142 LAP's and a couple of 2960S's to complete the LAN.
Now I know I can get the wireless phones going the next job is the tedium of adding them to the CME and creating DN's. Once that's out the way I'll move on to getting the features working. Expect more threads in the not too distant future!

Glad to hear it's working. I've got about 20 of those wireless phones on my enterprise WLAN. They're a bit of pain up front but after you get them running they're good to go. Make sure you have the AP density to allow for seamless roaming. General rule of thumb is each AP overs 5000 sq ft. Subtract 1/3 from that for voice and another 1/3 if you want to run location tracking. So, if you have a 10,000 sq ft building you would need 2 AP's for data. If your running voice you'd be better running 3 AP's for that amount of space. These are of course just quick guidelines, but something to keep in mind.

DHCP options here, IIRC 66 and 150 are the key ones, along with basic connectivity to the TFTP server, but sounds like you got it figured out.
Congrats and let us know what the PM's reaction is.

Unfortunately a non disclosure order prevents me from giving a fuller explanation of where these will be deployed. Suffice to say the area to be covered is considerably less than 5000 sq feet per floor. I have 8 access points spread over 3 floors plus one outside. The area has some challenges to overcome with regards to signal propogation so we routinely spec what would be considered to be far too many AP's for the size of the area in order to compensate for those challenges.

Now I know how to get it going I can erase start the lot and configure it with the actual deployment config.

Once again, I would like to thank you guys for your contributions which have all been really helpful.
