Aironet access-point 1231G reboots itself frequently...

Hi there,
We have one 1231G access-point which reboots itself after every certain time, its uptime has never crossed some 30 - 35 mins, usually it remains to 10 -15 mins. Some days ago, I saw a similar problem being discussed on thsi plateform but after the NetPro being changed, I could not find the progress on that thread. The guys in that thread suggested to physically separate the wireless controllers and then re-attach it back. Instead of doing this I tried physical reboot/power-cycle of thsi access-point. That access-point behaved normally for some days but after some that it aain posed the same problem. Kindly help me with probable solutions to it.
Thanks and regards,
Gaurav

Hi Scott,
The show stack command shows like:

This looks good to me, although let me know your thoughts on it.
One thing I have observed that the it showed a high CPU spike when it reboots and stops responding on the network. sho proc cpu his command, just after the reboot shows a spike of between 85 to 100% CPU utilisation. Any thoughts!

Hi Niham,
You can try few things to troubleshoot this -
1. check the reachability of Radius server from your wlc (ping).
2. verify the IP address of Raduis server configured on wlc.
3. wlc in the Radius server ?
4. Shared Secret must be same on wlc and in raduis server.
Plz do not forget to rate useful post.

Bootup order on Cisco Aironet Access Points

Hello folks
Could you please help me in clarifying the bootup order on Cisco Aironet Access Points
Does the SNMP Agent on the device start before the Startup config is copied to Running Config ?
Because everytime the Cisco Aironet Access Point restart , SNMP trap is generated from Admin down WLAN interfaces (Dot11Radio1/Dot11Radio0) mentioning "Administratively down " .
So my best assumption is that
Access point Restarts - > SNMP Engine starts -> Startup Config is copied to Running config -> Interface is made admin down -> SNMP Trap is sent
Is that correct?
Please help !
Anup

The Clean Access Manager (CAM) manages out-of-band Clean Access Servers (CASs) and switches through the admin network. The trusted interface of the CAS connects to the admin/management network, and the untrusted interface of the CAS connects to the managed client network.
When a client connects to a managed port on a managed switch, the port is set to the authentication VLAN and the traffic to/from the client goes through the Clean Access Server. After the client is authenticated and certified through the Clean Access Server, the port connected to the client is changed to the access VLAN. Once on the access VLAN, traffic to and from certified clients bypasses the Clean Access Server.
In most OOB deployments (except L2 OOB Virtual Gateway where the Default Access VLAN is the Access VLAN in the Port profile), the client needs to acquire a different IP address from the Access VLAN after posture assessment.
For Real-IP/NAT-Gateway setup, the client port is bounced to prompt the client to acquire a new IP address from the admin/access VLAN.
The below URL describe the configuration steps needed to set up your OOB deployment:

Dynamic VLAN Assignment with RADIUS Server and Aironet Access Points

Hi Guys,
I would like to go for "Dynamic VLAN Assignment with RADIUS Server and Aironet Access Points 1300". I want the AP to broadcast only 1 SSID. The client find the SSID ->put in his user credential->Raudius athentication->assign him to an specific vlan based on his groupship.
The problem here is that I don't have a AP controller but only configurable Aironet Access Points 1300. I can connect to the radius server, but I am not sure how to confirgure the AP's port, radio port, vlan and SSID.
http://www.cisco.com/en/US/tech/tk722/tk809/technologies_configuration_example09186a008076317c.shtml#switch
I go through some references:
3.5 RADIUS-Based VLAN Access Control
As discussed earlier, each SSID is mapped to a default VLAN-ID on the wired side. The IT administrator may wish to impose back end (such as RADIUS)-based VLAN access control using 802.1X or MAC address authentication mechanisms. For example, if the WLAN is set up such that all VLANs use 802.1X and similar encryption mechanisms for WLAN user access, then a user can "hop" from one VLAN to another by simply changing the SSID and successfully authenticating to the access point (using 802.1X). This may not be preferred if the WLAN user is confined to a particular VLAN.
There are two different ways to implement RADIUS-based VLAN access control features:
1. RADIUS-based SSID access control: Upon successful 802.1X or MAC address authentication, the RADIUS server passes back the allowed SSID list for the WLAN user to the access point or bridge. If the user used an SSID on the allowed SSID list, then the user is allowed to associate to the WLAN. Otherwise, the user is disassociated from the access point or bridge.
2. RADIUS-based VLAN assignment: Upon successful 802.1X or MAC address authentication, the RADIUS server assigns the user to a predetermined VLAN-ID on the wired side. The SSID used for WLAN access doesn't matter because the user is always assigned to this predetermined VLAN-ID.

Thanks.

I'm not sure if the Autonomous APs have the option for AAA Override. On the WLC, I can go into the BSSID, Security, Advanced, and there's a checkbox that I would check to allow a Radius server to send back the VLAN.
I did a little research and it looks like the 1300 may give this option but instead is defined as "VLAN Override". I've found the release notes for 12.3(7)JA5 (not sure what version you're running) that give mention and a link to configuring EAP on page 4: http://www.ciscosystems.ch/en/US/docs/wireless/access_point/1300/release/notes/o37ja5rn.pdf
Hope this helps

Can interference cause an access point to reboot?

I recently configured our WCS to send email notifications. Monitor > Alarms > Email Notification
I now receive emails from WCS stating that some access points dissassociate from the controller, and then another email stating they are back again. Not the same APs, not all at the same time, etc. We have 1200+ access points. A very small percentage... maybe one or two per day decide to leave the controller and then come back.
Looking at the controller, I see this is a true statement. I see that the access point's uptime is equivalent to the time is left the controller and came back again.
My question is... does anyone else have this configured, and if so, what was causing the access points to disassociate? I cannot tell if the access point is actually rebooting or simply wandering away from home.
Is there a way to see what caused the AP to leave and come back again? With nobody in the building at 7pm, I don't think it was human intervention. Other access points on the same switch, and they don't wander. I do wonder if interference or something else can cause an access point to reload.
The APs are AIR-LAP1210 on a 5508 running 7.0.98.0
Are there any known bugs that you are aware of?
Thanks in advance!
WCS has detected a change in one or more alarms of category AP and severity Critical in Virtual Domain root.
The new severity of the following items is Clear:
'802.11a' interface of AP 'ap02' associated to controller 'WLC-1 (10.10.10.1)' is up. Reason: Radio interface reset.
'802.11b/g' interface of AP 'ap02' associated to controller 'WLC-1 (10.10.10.1)' is up. Reason: Radio interface reset.
AP 'ap02' associated with Controller '10.10.10.1' on Port number '13'.
E-mail will be suppressed up to 30 minutes for these changes.

You are in luck. Like you we have 4500 radios and we turned on alerts and we got slammed on this as well. I will share with you some of the things that contriubuted to our problem. It just wasnt one issue...
1) We had 200 APs configured as a primary to 1 WLC. Well that WLC could only take 150. So when one AP jumped off there were 50 other aps interested in getting on. And when this happened we got an alert. We only fill 125 per wism today. This cut down on a good portion of our alerts
2) We disbaled ap fall back. Once the aps were where we wanted them we killde ap fall back. (no more bouceing around).
3) We had a few aps with link problems. Not many but a few. These aps would lose data connection but still keep power and not reboot. We either had to replace the patch cable or do a new run.
Take a few and investigate them. You will start to develop your own pattern.

Strange VLAN issue on aironet access points

I'm setting up some access points for WPA. I've ran into a strange issue. The client VLAN (VLAN that the users will be put into) is 1, and the native VLAN is 10. The RADIUS server is in VLAN 1 (but I have a test RADIUS server in VLAN 10 as well). I can connect from the access point to a RADIUS server in either VLAN, and from the RADIUS servers to the access point as well. When I point to a RADIUS server in VLAN10 authentication works fine. If I point to a RADIUS server that is located in VLAN1, and I put the wireless clients in VLAN10 it works fine. But for some reason when I have the RADIUS server and the clients in VLAN (1) and the native (BVI1) interface in VLAN 10 the authentication packets never seem to get to the RADIUS server. It is as if the authentication is being sources out of the wrong VLAN. I can?t find any docs to say that this isn?t a supported configuration.

Hi Shannon,
have a look here:

Significance of Native VLAN
When you use an IEEE 802.1Q trunk port, all frames are tagged except those on the VLAN configured as the "native VLAN" for the port. Frames on the native VLAN are always transmitted untagged and are normally received untagged. Therefore, when an AP is connected to the switchport, the native VLAN configured on the AP must match the native VLAN configured on the switchport.
Note: If there is a mismatch in the native VLANs, the frames are dropped.
This scenario is better explained with an example. If the native VLAN on the switchport is configured as VLAN 12 and on the AP, the native VLAN is configured as VLAN 1, then when the AP sends a frame on its native VLAN to the switch, the switch considers the frame as belonging to VLAN 12 since the frames from the native VLAN of the AP are untagged. This causes confusion in the network and results in connectivity problems. The same happens when the switchport forwards a frame from its native VLAN to the AP.

SG300-28P and aironet access points

Dear support,
does Cisco SG300-28P provide enough PoE to power access points 1550 and 1600?
Thank you

Hi Mireille, it should. The 1550 is 802.3af compliant.
The 1600 may be interesting because it can actually draw up to 15.4 watt of power and you may run into limitations of cable. It is also 802.3af compliant.

IPhone 5 reboots itself frequently

Hi,
I have a iPhone5 from Singapore retailer, 16G black. I upgraded to 6.0.2 right after I got it. The device would self-reboot every 20 mins to 1 hour when I am using it. At night when I am charging it, it also occassionally reboots itself. Also the battery life is short, averaging 6-7 hours from full to < 20%. I tried to reset, restore, took to the Shanghai Apple Store, but they couldn't figure it out. Anyone has any ideas?

Hi Jnsumanth,
If your iPhone continues to restart itself unexpectedly, you may want to follow the steps in this article to troubleshoot -
iPhone: Hardware troubleshooting
http://support.apple.com/kb/TS2802
Specifically -
Will not turn on, will not turn on unless connected to power, or unexpected power off
Verify that the Sleep/Wake button functions. If it does not function, inspect it for signs of damage. If the button is damaged or is not functioning when pressed, seek service.
Check if a Liquid Contact Indicator (LCI) is activated or there are signs of corrosion. Learn about LCIs and corrosion.
Connect the iPhone to the iPhone's USB power adapter and let it charge for at least ten minutes.
After at least 30 minutes, if:The home screen appears: The iPhone should be working. Update to the latest version of iOS if necessary. Continue charging it until it is completely charged and you see this battery icon in the upper-right corner of the screen . Then unplug the phone from power. If it immediately turns off, seek service.
The low-battery image appears, even after the phone has charged for at least 20 minutes: See "iPhone displays the low-battery image and is unresponsive" symptom in this article.
Something other than the Home screen or Low Battery image appears, continue with this article for further troubleshooting steps.
If the iPhone did not turn on, reset it while connected to the iPhone USB power adapter.If the display turns on, go to step 4.
If the display remains black, go to next step.
Connect the iPhone to a computer and open iTunes. If iTunes recognizes the iPhone and indicates that it is in recovery mode, attempt to restore the iPhone. If the iPhone doesn't appear in iTunes or if you have difficulties in restoring the iPhone, see this article for further assistance.
If restoring the iPhone resolved the issue, go to step 4. If restoring the iPhone did not solve the issue, seek service.
Thanks for using Apple Support Communities.

Thanks in advance!

Blackberry Z10 connection with an Aironet Cisco Access Point 1200

Hi everybody,
I'm trying without success a connection between a Blackberry Z10 and an Aironet Cisco Access Point 1200.
We have no BB Server, we would like just to connect the WIFI.
I've checked this points during the activation of the device:
There's no LEAP protocolle.
There's an EAP-Fast possibility.
There's Mac Address recognition possibility.
When we try to use the EAP-Fast possibility, we generate a .pac file, but i don't know where i can put this file so that the Blackberry recognize this file. I've search the whole day and didn't find anything... there's simply no explanation with the Z10 around the .pac file without a BB Server.
I've try the Mac Address recognition and it simply doesn't work (no error the search time is too long)
Every other older smartphones - Blackberry (there's 4 devices) are working.
Anyone have an idea about? a suggestion? a list of compatible WIFI Devices?
Thank you ahead.
Have a nice day.
Joel.

Sorry i don't understand your answer.
I'm not a developper but a system administrator.
I just would like to use a Balckberry Z10 with our Wifi/Router Aironet Access Point 1200.
not more.

Satellite A305-6825 frequently rebooting itself

My laptop reboots itself frequently. This happened while I was running the original Windows Vista that was shipped with the macine, and continues to happen now that I have upgraded to Windows 7. Recently, the laptop also started to get hang-up (freeze-up) at times. Please advise. Thank you in advance.

Thank you Peter.
Before getting your suggestion for a clean-up start, I disconnected the power supply after charging the battery to full capacity and have used the laptop without a glitch this way for two days (on battery power ony). Any ideas as to what could be causing the reboots before, when the power supply was connected?
Thank you in advance,

Guest use of a Aironet 1131AG Access Point

I have 2 WLAN's using (mostly) D-Link products - one is for staff only and the other is for guests, and is totally separate from our LAN.
I'm disappointed with D-Link and want to change-over to all-Cisco AP's. I'm fairly satisfied with the 1131 and wish to build on it.
The manual mentions a guest SSID, but I have reservations about network security. (I am thinking of using a single WLAN with multiple SSID's to handle the staff and guests.) What is the opinion on this forum on this issue? (I'm very new to Cisco and classify myself as little more than a beginner with wireless in general.)

Is my aironet 1100 access point dead?

Hello,
I purchased a second hand cisco aironet access point on Ebay and I am having trouble getting into the configuration program. I have reset the device back to factory defaults and I get green led's when I plug it in. I have it connected to a pc running win xp via an ethernet patch cable. I have assigned 10.0.0.2/24 to my pc and when I ping the access point I am getting over 75% packet loss. The web browser will bring up the login box after a minute but after that nothing. Any suggestions? Is it dead?
With Regards,
Aaron McQuaid

Aaron,
Did you get this resolved?
I have the exact same problem. I am using an AIR-AP1121G and I can't see the AP anywhere. I can find it on my firewall sometimes, but sometimes the IP Address changes and sometimes it disappears completely.
I am pretty new to this type of AP. We have one at work I love, but this is my first one I am configuring.
TIA

1702i access point presales questions

I am trying to clarify the capabilities of this device before purchase. One of the points of confusion is that the configuration guide applies to the 3700 series, the 2700 series, and the 1700 series. If there is a more appropriate manual to use than the "Cisco IOS Configuration Guide for Autonomous Cisco Aironet Access Points" for the 1702i, then that would be useful information.
SSIDs: The manual indicates that the access points are capable of 16 SSIDs running simultaneously, but it doesn't make any distinctions between each of the series. Can I assume the 1702i is capable of 16 SSIDs, and 17 VLANs, like the WAP371?
DHCP server capabilities: P 5-25 of the manual shows how to use the internal DHCP server capabilities of the unit, but it is not clear to me how many instances, or pools, I can make. Am I limited to only one set, applied to one subnet, or can I define a different pool and subnet for each of the 16 SSIDs?
Specific model: The manual refers to the 1700i, but it looks like the model available is the 1702i. Are there any differences in the 1702i version?

"you will also see what access points that is supported on": My point was that the configuration guide did not say whether 16 SSIDs were supported on some or all of the series. That was my reason for asking the question (page 7-2 of the manual)
"The data sheet of the APs of the comparison guide will show you the feature difference of the access point": You must be looking at a different data sheet than I have been able to find:
http://www.cisco.com/c/en/us/products/collateral/wireless/aironet-1700-series/datasheet-c78-732347.html
a search for "SSID" on the page had no hits.
also the comparison between 1700, 2700, and 3700 series showed no hits for SSID:
http://www.cisco.com/c/en/us/products/wireless/buyers-guide.html#~indoorac,
"DHCP is strictly for that access point and it's always prefered to use a true dhcp server and not the access point itself."
It sounds like you may have misunderstood my question. I'm asking whether the DHCP server capability can assign a different IP pool for each SSID. The "Understanding Multiple SSIDs" section on P 7-2 shows that a different VLAN may be specified for each different SSID, but I can't tell from the "Setting up the DHCP Server" section on P 5-24, whether this can be done for different IP address pools, or just for one.
For example:
The SSID "InterEquipment" would use VLAN 2, and the subnet 192.168.2.0
The SSID "Staff" would use VLAN 3 and use the subnet 192.168.3.0
The SSID "Guest" would use VLAN 4 and use the subnet 192.168.4.0
Could the 1702i act as the DHCP server for all of these SSID/Vlan/subnet combinations, or just one of them?
Concerning your comment "...it's always preferred to use a true dhcp server and not the access point itself." , what is it about the access point that makes it not a "true dhcp server", and why is it "preferred" to use something else?
