WLC 5508 APs showing Line Protocol Down
I have a WLC 5508 (software version 7.5.102.0) and it has 175 APS (mixture of 1131, 1142, 1602, 2602). Recently I've noticed that
about 40 of those APs don't work on the 2.4G Dot11Radio0. sh int dot11 0 shows me:

I've tried restarting the interface,to no avail, but rebooting the whole AP does bring it back up, but I expect that's a solution to the symptom, not the problem.
Hi Sean,
There are certain related bugs of this version. You may need to check whether you are hitting one these. I would suggest staying in 7.4.121.0 code would be a good idea unless you require new features available in 7.5 or 7.6.

What trigger Line Protocol Down?
Hi,
Recently I encountered a problem on "line protocol down" as I'd posted on 4th April.
Could anyone direct me to any webpage or sites where there's a detail explaination of how & what would trigger a line protocol down. Or these kinda data-link failure. Thanks!
With regardsHi Friend,
There could be few reasons majorly physical layer issue when the line protocol goes down.
Can you please update which interface was showing line protocol down. Logical interface (SVI) on layer 3 switch, physical port on layer 2/3 switch or any physical interface on router?
If it is a physical interface on layer 2 switch it is majorly a physical layer issue or may be that particular vlan asscosiated to that port got deleted.
If it is a layer 3 logical interface showing line protocol down may be there is no vlan associated to that vlan configured on layer 2 switch port or no trunk carrying that vlan on that switch.
HTH, if yes please rate the post.

Multiple DHCP scopes on WLC 5508 (not showing leases?)
I have 2 DHCP scopes set up on a wlc 5508, one for the AP's and another for a wlan, the leases for the AP's scope show up, but the one that the clients on the WLAN are on do not show up in the "show leases" is that a bug? normal?
Customers using Cisco Unified Wireless solutions have been reporting issues with the DHCP support provided on the Wireless LAN Controller (WLC). Some of these issues are software bugs or debugability problems. Others are due to lack of proper understanding on the DHCP implementation.
This document describes the different DHCP operations on the wireless controller, which provides consistent and accurate information to customers in an effort to reduce the related customer issues and TAC cases.
Please refer to the following link: http://www.cisco.com/c/en/us/support/docs/wireless/4400-series-wireless-lan-controllers/110865-dhcp-wlc.html -
Okay, this might seem like a really stupid question but it's got me stumped.
What the hell does "line protocol down" mean and how the hell do I fix it? I'm using a Cisco 2500 series router, and it's occuring on serial port 0 on BOTH routers. I've checked, double checked, re double checked, and triple checked (quadruple checked?) the wiring and the physical wiring is fine...
Can anyone provide any insights to this at all for me? I'd greatly appreciate it.
TIAThe line protocol state (up or down) reflects the layer 2 status of the interface. If your serial interface is saying that its state is up/down it means that it knows that it is plugged into something on the interface but that there is a layer 2 connectivity problem.
The nature of how the router determines the layer 2 status depends somewhat on the type of interface. On Serial interfaces the determination is based on the keepalives. So basically what the router is saying is that keepalives are not working on the router. There are a couple of things that can prevent keepalives on the serial interface, such as different protocols being configured (one end may be Cisco HDLC and the other end is PPP). If it was Frame Relay a mismatch of LMI type may cause it. Given your comment about using 2500 and that both sides are showing protocol down I am going to guesss that you have the routers configured back to back. And I am going to guess that you have not configured clock rate on whichever router has the DCE serial cable connected. When routers are back to back and do not connect to provider equipment, you need one of them to generate clocking (and it needs to be the one with the DCE cable). So check your cables, find which one is DCE, and configure clock rate on that router.

WLC 5508 rebooted but still showing high uptime
Hi all,
I had to reboot our production WLC 5508 last night to apply a new adder license, which increased our AP count by 25.
We run a DMZ mobility controller alongside the primary controller, which handles our mobile/guest WLANs using a Mobility Anchor. Normally we would reboot both of these due to issues with the anchor after the primary is rebooted.
So last night I rebooted the primary after installing the new adder license. Once it came back up, I checked the license count and it had increased as per the new license. After that I rebooted the mobility controller, and waited to ensure that this came back up.
Almost straight away, all the AP's had re-associated with the primary (all 96 of them), and clients were starting to show up. I checked the same on the mobility controller (although this does not manage any AP's) and I could see mobility clients associating with this also.
The problem came this morning, when none of the mobility clients that were connected to the mobiltiy WLANs were able to get to the Internet, or any kind of outside connection. This is the typical issue we see when our core switch gets rebooted, or the primary on its own, without rebooting the secondary.
So to troubleshoot this morning the first thing I suddenly noticed was the uptime on the primary controller. It showed 298 days!!
Anyone seen this behaviour before? The WLC DID reboot - I watched it go down and POST again. Why would the uptime counter not reset?
We're on firmware 7.2.111.3 - which I realise is pretty old, but due to CIsco screwing us over with a limited upgrade path, we are not able to upgrade it yet (AP hardware not supported on any of the newer code above this version).
Any help appreciated!In response to Sandeep, here's the sh sysinfo output:

Why WLC 5508 shows message " Operator changed to 11g mode" & AP is rebooted
Dear Sir,
I have faced some problem with Cisco 1520 Series APs.
Since few days, We got the log in wlc 5508 like this
"AP 'MAPNSY#WMI3', MAC: ac:a0:16:5c:45:00 disassociated previously due to AP Reset. Uptime: 0 days, 00 h 22 m 52 s . Last reset reason: operator changed 11g mode."
& then AP is rebooted.
Here, I attached the screenshot of WLC 5508 Log.
Plz, help us.Not the IP addr of the management interface.. I am telling about the Dynamic AP manager interface that you have configured which is for the AP to register..
Please post in the output..
show interface summary (mentioning the interface used for APs to join)
Regards

5508 pair show "Down" as data sources for Netflow
I've setup my 5508s to monitor and export netflow to Cisco Prime Infrastructure but no data populates in the expected tabs. When I check Admin-> Data Sources they show up as "down", while other netflow exporters (ASA1000s I used to test) show as "up". I verified in the WLC CLI that they are exporting flows. Thoughts?
WLC show flow exporter stat:
Exporter-name: CiscoPrime
Total Flows Sent: 69536
Total Pkts Sent: 4021
Total Pkts Dropped: 0
Last Sent Time: Thu Aug 15 15:24:29 2013Hi Marcin,
You are most welcome my friend I think the great NetPros in this thread
offer some excellent tips and strategies for this plan as well as the restrictions
you will encounter moving forward. You will likely want to make the 5508 the
primary controller with an eye on moving away from the 4400 at some point
due to it's EoL and inability to run the latest code versions.
Cheers!

GigabitEthernet1/1 is up, line protocol is down (notconnect)
Hi All,
I am really curious to investigate a possible reason behind this error message.
During the configuration of a port channel bundled with 2 links I have the error in the subject but only for one side of the connection and only for one link part of the port channel.
On the other side the corrispondent interface was up/up and the other link part of the port channel was able to go up with no issue (for all the configuration is the same).
Background info:
- The link in discussion was connecting the two Multilayer swicthes before the configuration of the port channel with no issue
- The port channel is a L2 etherchannel
- What was done was simply to shutdown the interface on both swicthes, add the command channel group xx mode on on both side of the connection and then bring up the connection with the result above showed: one side up/down (not connect) and the other side up/up
I am excluding problem with the configuration. The reason is simple: i just reply the configuration to the all links (total 2) part of the port channel with no issue.
Can be a cabling problem (SFP)? Again keep in mind that before the change, this link was active with no issue for 4 years.
Thanks all.Hi Peter,
Find below the requested output.
I forgot to mention something:
The etherchannel is a L2
The mode employed to create the port channel was on
In any case what I did in the meanwhile was:
- To check the cable -> It is ok
- I did not check the SFP but I configured the involved interfaces as L3 and I bringed up both with no issue. They are connected so I am assuming that the SFP is ok. Do you agree?
At this point due to the fact that:
Configuration is working properly for the second link part of the same portchannel
The cable and sfp is ok
The only problem that I can see here is the Etherchannel Modes adopted: I heard that on modes is not the best practice. The best is use the LACP

WLC 5508 LOAD BALANCING APs to HA-SSO
Do somebody knows what´s going to happen about configuration when you migrate 2-WLC 5508 giving wireless services correctly, using load balancing with the APs to HA-SSO mode???
At this time we have some AP groups in WLC1 and in WLC2 we don´t have the AP groups, what´s going to happen with the configuration of both WLCs, both configuration are going to be merged??
REGARDSWhen you covert the pair into SSO, all the APs will go to the ACTIVE unit. No unit will "live" in the standby unit because this unit will "share" the AP-support license between the two.
This is the first step you need to get sorted. Send an email to [email protected] and give them the exact details of what you want to do (i. e. AP SSO) and then provide the serial number of your nominated active WLC and the serial number of your nominated standby WLC. -
I have a blue veritcal line going down the middle of my screen turned my iMac and it showed up. What can that mean?
Hard to help without knowing which variant of iMac you have. They've been in continuous production since 1998 in four major families, and what works for one familiy of iMac may not work to diagnose one from another family.
Doing "About ths Mac" will show the processor info. Post what it says about your processor (and Mac OS version while you are there) and that will narrow what family of iMac you have.
This forum section is for the three iMac families made before 2006. -
WLC 5508 : session disconnected when one lag-port is down.
Hello,
I have a WLC 5508 ( version 6.0.182).
When the port1 and port2 are connected ( The switch is configured with a etherchannel in forced mode) everything works fine: There is traffic on the 2 ports.
When I disconnect one of the 2 ports, I can still ping outside with my PC client, but all my tcp sesssions goes down and I even cannot restart my session. The only way I found is to do a "Disconnect / Reconnect" on my PC wireless connection.
Do you know this probleme ?
Is it a way to avoid it ?
Michel MisonneCSCth12513 LAG fail-over does not work on CT5508
This bug is fixed in the special release available through TAC : 6.0.199.157 and 7.0.xxxx
Hope this helps.

Cisco WLC 5508 assigning different SSID to few APs
Hello Everyone,
I have a WLC 5508 runing 8.0
Presently one SSID is assigned to all th APs registered with my WLC.
I want a different SSID to 2 of APs. Can anyone tell me how to do this?Depend on WLAN ID number as well.
1. if WLAN ID number is greater than 16, then those SSID not visible in "default ap-group" & only in the APs in particular AP Group.
2. if WLAN ID number is lower than 16 then, by default it will advertise in APs in "default ap-grop". So if you add that WLAN to particular AP Group, then that WLAN advertised by APs in both AP groups (default & specific AP group)
