Impossible. Pretty sure you're missing something. Wondering what type of authentication you configured on the SSID and how are you handling the FT.

Hi all,
I'm setting up a FreeBSD box to be used as NTP server within my network, which most of the time will be a stratum 2 NTP.
While I do have some sync problems between the FreeBSD box and the Stratum 1 (work in progress due to a firewall between them) I do see some strange errors on my routers and switches while issuing "show ntp assoc det".
Please see below in bold:
configured, ipv4, insane, invalid, unsynced, stratum 3 ref ID 81.21.76.27 , time DF66EA6B.C498C97E (10:50:51.767 CEST Tue Oct 9 2018) our mode client, peer mode server, our poll intvl 256, peer poll intvl 256 root delay 33.44 msec, root disp 876.63, reach 0, sync dist 16836.15 delay 0.00 msec, offset 0.0000 msec, dispersion 15937.50, jitter 0.00 msec precision 2**21, version 4 assoc id 35170, assoc name 144.210.60.118 assoc in packets 4710, assoc out packets 4786, assoc error packets 3988 org time 00000000.00000000 (01:00:00.000 CEST Mon Jan 1 1900) rec time DF66EACB.8DC1D5AC (10:52:27.553 CEST Tue Oct 9 2018) xmt time DF66EACB.8DC1D5AC (10:52:27.553 CEST Tue Oct 9 2018) filtdelay = 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 filtoffset = 0.00 0.00 0.00 0.00 0.00 0.00 0.00 0.00 filterror = 16000.0 16000.0 16000.0 16000.0 16000.0 16000.0 16000.0 16000.0 minpoll = 6, maxpoll = 10
While the assoc errors are incrementing, there is another odd thing: the reach value is most of the time 0 (0 the received updates are minimum - 377 constant updates). Now I'm not sure if this value is regarding the stratum 1 NTP or to my NTP (no firewall between these devices).
Ntp In packets : 41034
Ntp Out packets : 55569
Ntp bad version packets : 0
Ntp protocol error packets : 0
Ntp Software Name : Cisco-ntpv4
Ntp Software Version : Cisco-ntpv4-1.0
Ntp Software Vendor : CISCO
Ntp System Type : Cisco IOS
Can anyone explain how are the assoc errors generated?
Thanks,
N

Hi @Cisco SE,
Very important to understand it's the client's decision to which AP will roam.
You can only influence this decision using:
802.11r;
802.11k;
802.11v;
you're saying the APs are quite close one to the other, you may want to disable the lower data rates on the controller - this is quite a powerful feature and I think will work for you. Check the link speed while you are in the other room, this way you will know what to disable.
You may want to ask your users to "forget" the network and rejoin, after enabling/adjusting the roaming features.
Cheers,
Neo

According to table 10 from https://www.cisco.com/c/en/us/products/collateral/switches/catalyst-2960-x-series-switches/data_sheet_c78-728232.html your switch should be able to provide 30W per port for 12 APs.
Check the running-config and look for a line similar to power inline consumption default 15400.
Thanks,

I assume 10.7.1.3 is your dhcp server.
The router is only forwarding the requests to 10.7.1.3 - if you're using it, leave it there.

Hey,
You should be fine, just be sure service DHCP is enabled on the ISR. If disabled it will disable the ip-helper feature as well.
Good luck.

Hi,
I had a similar problem with a few 3802 (minimum 30W) and 3560-x switch.
In my case, the switch was capable of 802.3at or (POE+) only when was configured with 2 power supplies (1x1100W + 1x750W/ 2 x 1100W). While the switch was configured with only one PS (1100W), the APs were sucking only 15.4, but no other errors was shown in the logs, the APs were joining the controller but with the radios down.
You may want to check the specs, regarding the POE capabilities with different PS.
I suggest leaving only 3 APs connected, and see how it goes.
Kind regards,
Neo

You are very correct.
That would be my next step in troubleshooting this problem.
Unfortunately I can't update the code at this moment.
I was just looking to find out if there are any other people that faced the same problem and what steps they followed.
After more research, I realised the switch will need one more power supply in order to work under the 802.3at standard. I did not test as we bought the righ power injectors, but I assume for a 3560x-48 I will need 2 PS:
Setup1 - 1 x 1100 W and 1 x 750 W
Setup 2 - 2 x 1100 W
Otherwise the switch will be just 802.3af.
Found this in their documentation. Not that happy, as Cisco is advertising the sw as POE+. I had to go through all their documentation to find this bit. I wonder how the switch will perform with a new code.

Hi all, I do have 3 x AIR-AP3802I-E-K9 and a WS-C3560X-48P with a PS of 1100 W, capable of 802.3at. I can get the APs on the WLC, but they're not broadcasting, and clean air is off. After some troubleshooting, even if I configured the switch interface for max power (see below) the AP seems to suck no more than 15.4 W, which is...confusing, as on the WLC, it says Medium Power, but no alarms, though the LEDs are flashing in all colours. The remaining power is over 600W on the switch so here we're fine. See below the interface conf: interface GigabitEthernet0/8 description *** Wireless AP *** switchport trunk encapsulation dot1q switchport trunk native vlan 40 switchport trunk allowed vlan 40,58 switchport mode trunk load-interval 30 power inline port priority high power inline static See below the show power inline output showing the static power conf of 30 W per interface.

Another strange thing is that on the WLC it says connected with medium power, and not indication of low power here (only on the APs logs). Any thoughts ?

Hi,
I thinkg AIR-AP2802I-x-K9 C comes with the Mobility Express feature (you can use the AP as wireless controller up to 25 APs), while the simple version comes just as LWAP (can be used just with a controller).
Kind regards,

Hi all,
My company just purchased 3 x AIR-AP2802E-E-K9. While booting, all of them are looking for a wireless controller. Since we don't have one, I'm trying to convert one of APs to Mobility Express.
Checking Cisco's documentation for Aironet 2800 (http://www.cisco.com/c/en/us/td/docs/wireless/controller/technotes/8-3/b_Cisco_Mobility_Express_Deployment_Guide.pdf) they're saying:
Step 1 Enter enable to go to privileged execution mode.
Step 2 Enter show version on the AccessPoint CLI.From the show versionoutput, you can determine the AP Image type and AP Configuration and can then proceed with the conversion process.
• Case 1: If the AP Image type is MOBILITY EXPRESS IMAGE and AP configuration is NOT MOBILITY EXPRESS CAPABLE, only conversion of AP Configuration is required. Go to 5.
• Case 2: In the show version output, if the AP Image type and AP Configuration are not available, download of the Mobility Express image and conversion of AP Configuration is required. Go to 6.
Step 3 Enter the command below to change the AP Configuration to MOBILITY EXPRESS CAPABLE. AP#ap-type mobility-express tftp:// / Since the Access Point has an AP Image type: MOBILITY EXPRESS IMAGE; a new image does not be downloaded. After the command is issued, the Access Point reboots and comes up as AP Configuration MOBILITY EXPRESS CAPABLE .
Step 4 If AP Image Type and AP Configuration is not available in show version, it means that the AP is running CAPWAP image. To do the conversion, execute the command below: AP#ap-type mobility-express tftp:// / Example: AP#ap-type mobility-express tftp://10.18.22.34/AIR-AP1850-K9-8.1.120.0.tar Starting the ME image download... It may take few minutes to finish the download. Note After the image download is complete, it writesto flash followed by a reboot.
I feel confused, when I'm trying to connect the console cable to the AP I can't do anything, since it is constantly looking for a controller and I can't get the chance to type anything in. In other document (http://www.cisco.com/c/en/us/td/docs/wireless/access_point/2800/quick/guide/ap2800iegetstart.html#pgfId-69227) they're saying:
The access point console port is enabled for monitoring and debug purposes. All configuration commands are disabled when the access point is connected to a controller.
The AP is an AIR-AP2802E-E-K9, 8.2.20.16
Does anyone have any idea how to switch it to Mobility Express ?
Thank you!

Hi jeswinsamuel and thanks for taking the time for writing. You're right regarding the one ap to act as a controller up to 25 aps, using the Mobility express feature. I just need to know if they can be configured, like you said, in the traditional standalone solution. From my point of view, configuring one AP to act as a controller for an x number of AP's, is nothing but getting the AP ready to be part of a network managed by a controller, if you get my point.

Hi all,
I'm trying to find out the difference between AIR-AP2802E-E-K9C and AIR-AP2802E-E-K9. I read a few documents and found out that the "C" comes from configurable but nothing more than that. Do these AP's need an wireless controller to work ? Can they be configured to work in a standalone setup ? (only ap's without wireless controller?) I suspect it depends on the software running on them but I want your opinions as well. Kind regards,
Neo
