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
Surendra

Wlc 5508 webauth subnet mask change issue
Recenly l changed the network subnet for a particular wlc interface and scope and also an upstream router and for some reason it would only allow me to use a /24 Host mask as my plan was to go to a /22 mask to allow for over 1000 hosts within this scope.
The Upstream Router which is a ( RV042 ) had the following original config :
192.168.1.1
255.255.255.0
I have noticed this device will not let me change the mask from a /24 to a /22 as you can only change from a pre-defined list of masks and you cannot manually add any either..
New Config
10.10.0.10
255.255.255.0
WLC 5508 Controller Interface
Original Config
192.168.1.25
255.255.255.0
192.168.1.1
New Config
10.10.0.25
255.255.252.0
Scope
Range : 10.10.1.10 - 10.10.3.254
Mask : 255.255.252.0
Network : 10.0.0.0
Router : 10.10.0.10
When l reconfigure to this addressing the wireless clients connect and get the new dhcp scope details but following this the webauth screen doesn't appear not allowing them to connect meaning there is no routing of traffic / internet access.
If l modify the above interface and scope masks back to a /24 - 255.255.255.0 the the wireless clients connect and webauth appears to prompt them to accept the terms and conditions and connect thus giving them internet access.
It looks like an issue with the mask ? The main reason l am trying to change the subnet addressing is because the standard /24 mask is not providing enough dhcp addresses and we have had times were the scope has been exhausted due to the public connecting and disconnecting as the lease perod of 2 hours holds onto the address before expiring meaning there is not enough available addresses for people to connect.
I would of thought that the upstream router ( RV042 ) even though it is only a /24 mask would still route the traffic coming from a WLC Controller interface with a /22 mask ?
Hopefully someone can suggest a solution ?
Thanks SimonHey Scott just getting back to this issue.. If for instance l can modify the wlc interface and Scope to have a /22 mask ( 1022 Hosts ) and my upstream Router ( Cisco RV042 ) can only provide a /24 or higher mask then does that mean l am still limited to a range of 254 hosts ( /24 Mask ) ? Would this mean l need to look into replacing my upstream Cisco RV042 VPN Router ?

Operation ' Change Attribute TSTATE ' could not be carried out for Request
hi,
i am unable to delete the request Id from DSO. and when i checked that, it says request is partially activated(error occured during the activation)
and when i checked the logs i got the following error messages:
Operation ' Change Attribute TSTATE ' could not be carried out for Request 609249
Termination in problem report 'RSS2_DTP_RNR_SUBSEQ_PROC_SET' in row ' 361'
i even thought it was BASIS issue but it was not.
due to this error the process chain is failing daily
kindly help
regards
lakshhi arvind,
i tried using the both the methods you had mentioned, i am able to delete the request at that moment but its again coming back, i think as it is a partially activated request so may be that is why it is happening
but the problem is still there

WLC 5508 Syslog send to custom port
We have added Splunk to a monitoring systems and I would like to send my wlc 5508 log messages to it. We have the Syslog Data Inputs on that server are all TCP and we would like to maintain tcp only if possible. I do need to be on a custom port other than 514. We are on 7.4.100.60 on a HA pair of 5508's. Does any on have any insight on changing the syslog port number in the WLC config?
I too am using Splunk for capturing WLC Syslog. With regards to the destination port of the Syslog, I don't know how to change it. However, to get around this I have set up a Splunk Forwarder with Syslog-NG. Basically Syslog-NG listens on any port number/protocol you define and writes logs to a log file name $hostname$.log. This means I could have x different WLCs sending Syslog to Syslog-NG on UDP 514 and Syslog-NG will write the syslog from each host to it's individual file.
From their I've configured Splunk forwarder to monitor each file and forward the logs on to Splunk. You can forward to any port/protocol you wish.
Also remember to do this
config logging debug syslog enable
On the controller. Otherwise you won't see the messages you expect. -
WLC 5508, vlan select, reserved address in external DHCP server
Hi guys,
I have a deploy with a WLC 5508 version 7.0.116.0, APs mode local and vlan select feature enable. The issue is that the reserved IP address in external DHCP server not work. The DHCP contains a reserved IP address associates with mac address, but the assignement of IP is not match with de policies in DHCP. All others services operate normally.
This reserved assignment operate previusly to modificate the WLAN to vlan select feature. Help me to improve this situation.
Thanks.-
Best regardsHello Abhishek, thanks for you quick answer....
the link was a document used for the deploy, but not especifict nothing about the reserved IP address for particular host. In other words, the reserved IP address (through MAC address) in external DHCP server not work when "vlan select" its enable. -
Hi All
I want to migrate from WLC 4400 to WLC 5508. currently on WLC 4400 we got 10 AP are connected with 5 SSID having different authentication method. On WLC 5508 If I create the same SSID with same key, will I need to reconfigure anything on end user PC and smart devices
any tool to migrate wlc 4400 config to wlc 5508
cheers
VishalThanks Scott, some more inquiry
how to reboot the AP from the controller. ( I see 'Reset AP' - this option to reboot or something else)
how to disconnect all users connected to specific SSID from controller
Can AP model 3702 work with WLC 5508, do we need specific software version
cheers

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:

As you may notice, the uptime has now reset, but thats because I had to reboot it again this morning. I didnt grab the output before the second reboot. It seems whatever issue caused the uptime counter not to reset didnt occur this time.
Very odd. -
I connect a copper SFP on port 2 of WLC 5508 to a ASA 5510 firewall. The links between two devices are down. Since ASA 5510 only support 100 full, how do I change port speed on port 2 to 100.
ThanksDoes this mean, I couldn't change port speed on the WLC?
Yes you can. You can change the speed setting to GIGABIT, nothing less.
Why do I need to buy another Gigbit switch for 2 connection?
What do you mean by "another"???? Do you have an existing GigabitEthernet switch that you can connect the WLC into?
You need a GigabitEthernet port to connect the WLC's GigabitEthernet port. And then you can have a FastEthernet port to connect the SAME SWITCH to your ASA.
WLC --- (1000BaseTx) --- Switch --- (10/100BaseTx) --- ASA
Does this make sense to you? -
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.

All the message dates in the message list changed in every mailbox to a recent date, I don't know why.. The dates within the messages' headlines themselves remained correct. How do I re-establish the correct dates also in the mailboxes' message list?
First thing is to forget all the complex configs and just try to schedule the report to run once now, no alerts, no notifications, no nothing.
Does that work?
Then you can build up the schedule, to see where the problem is coming from.

Why does my IN operator change the datatype
Hi
This doesn't make any sense, but i'm hoping there's an obvious answer which you guys have seen a million times before.
I have this criteria in my WHERE clause
AND rpg_id = (SELECT rpg_id
FROM integration.rep_elig_groups
WHERE pel_id IN(34))because of this clause no results are return in my query. However if i use a to_number function like this:
AND rpg_id = to_number(SELECT rpg_id
FROM integration.rep_elig_groups
WHERE pel_id IN(34))OR
AND to_char(rpg_id) = (SELECT rpg_id
FROM integration.rep_elig_groups
WHERE pel_id IN(34))i get the expected results returned.
The sub query:-
SELECT rpg_id
FROM integration.rep_elig_groups
WHERE pel_id IN(34)returns the value 226. rpg_id in this table is a NUMBER datatype. As is rpg_id in the original outer query.
I looked at synonyms, views, and other objects it might be using for the rep_elig_groups table, but there are none.
Then i tried changing the IN operator for an EQUALS operator and would you believe it, it worked.
AND rpg_id = (SELECT rpg_id
FROM integration.rep_elig_groups
WHERE pel_id IN(34))can someone please explain what ORACLE is thinking here!!!
Many thanks
