Cisco 2802i - Blue, Red and green flashing LEDs

ejdrijin1 — Mon, 05 Jul 2021 14:30:17 GMT

Hi,

I have a Cisco AP 2802i and I have installed the Mobility Express however the AP LED's is still flashing (Blue, Red and green). I was reading and found out that these flashes mean that the AP is attempting to discover a WLC.

I was under the impression that the AP will become the WLC once Mobilty Express is installed. Because of this also the SSID is not broadcasting.

Can some one guide me and tell me what could be the issue?

Thanks.

Console into the AP and post

Console into the AP and post the entire boot-up process.

That is NOT the boot-up process.

Bootup is showing that the AP is looking for a WLC but nowhere is it stated what the IP address of the WLC is (unless it's been deleted).

Hi Leo,

Hi Leo,

Thanks for your reply.

I was under the impression that the AP will automatically become the WLC. Am I wrong?

If you are saying about this line, I have removed the IP:

[*08/07/2017 11:06:23.1504] ethernet_port wired0, ip 1, netmask 255.255.255.0, gw , mtu 1500, bcast , domain c waiting for POE negotiation to complete

Thanks.

Yes I meant - I was under the impression that the AP will automatically become the WLC when converted to Mobility Express.

Then I noticed that under APs I had different tabs, and the IP had an IP and then in the controller tab it had another IP. Should that IP be the same?

Thanks.

Was this ever resolved? How?

Thanks

They were probably wrong about what the error was, when a 2802 is blinking red, green and blue it means that it doesn't get enough power (it needs poe+ but it hasn't negotiated to poe+) and therefore doesn't bring up its radios.

Cisco IOS errors	Red	Software failure; try disconnecting and reconnecting unit power
Cycling through red, green, blue, and off	General warning; insufficient inline power

Exactly and the clue was in the line of log which the AP kept repeating:
"waiting for POE negotiation to complete"

The other common mistake with ME is people not understanding that the WLC and AP components run like separate virtual machines and both need an IP address. Either both must be statically configured, in the same subnet, or you need a dhcp server which can provide both with an IP address.

It sounds like the way your Cisco AP 2802i is set up as a manager in Mobility Express mode is wrong. When the AP's LED flashes blue, red, and green, it means it's still looking for a Wireless LAN Controller (WLC) because it hasn't been set up as one yet. Make sure the AP is set to work in controller mode and that the Mobility Express image is installed properly. You may need to reset the AP to its original settings and set it up again, making sure that the Mobility Express software is loaded correctly and that the AP is designated as the main controller. Once everything is set up right, the SSID should spread as it should.

No, if the AP is looking for it's wlc it will flash red and green. See below.

EDIT: Removed the table and inserted an image instead.

EDIT2: Realized that the table is WRONG, atleast for the 2802, if a 2802 flashes blue, red and green it needs more power to bring up its radios, and if it flashes red and green it is in its discovery process.

EDIT3: Removed the table as it was wrong and probably causes confusion. See the table from @Rich R instead!

@Aina William have you been copy/pasting chatgpt (or other AI chatbot) answers into questions you actually don't understand anything about? I see you've posted a bunch of other similar type of answers on other threads. This type of content is neither helpful nor welcome in these communities. If you have experience or knowledge that can help with the original question, or you have specifically checked the correct answer yourself in the documentation then you're welcome to share it with the community. Pasting in the wrong answer about something you don't know anything about yourself doesn't help anybody and is just going to confuse.

The LED sequences on different AP models are different so you cannot just quote a generic answer. @Denniz had already provided the correct answer so why would you follow that with a wrong answer?

Rich R — Mon, 05 Aug 2024 08:17:52 GMT

I would just remove that table @Denniz to avoid further confusion <smile>
@Aina William appears to be a serial chatbot answerer.

The 2802 documentation is at https://www.cisco.com/c/en/us/td/docs/wireless/access_point/2800/quick/guide/ap2800iegetstart.html#40401

The answer is in the last row of the table.

I am not sure how Aina got the impression that he or she is the moderator here, any answer or comment is appreciated, up to the participants to figure out what is helpful and what is not, thanks guys.

Re: Cisco 2802i - Blue, Red and green flashing LEDs

Rich R — Mon, 05 Aug 2024 08:12:55 GMT

Aina did not, but Aina did post similar answers on numerous different threads within a small space of time, right after joining. The regulars here have seen this behaviour before many times, and discussed amongst the community VIPs and moderators, and I will continue to call them out where I see them. There's nothing wrong with sharing answers that you might have been able to get to with the help of searches and documentation, preferably by sharing the reference documentation links. But copy/pasting an answer you got by pasting the original question into a chatbot, without any knowledge of the topic yourself, defeats the purpose of these communities, especially when the answers are wrong, as I can assure you they very often are. The chatbots still haven't mastered the art of understanding the finer nuances of different models and brands of AP for example (we've seen answers for other vendors products being provided before). No doubt the technology will get there eventually but it isn't there yet. At that point Cisco will have the bots answering everything in the communities. They already have a limited deployment on some communities only, where the bot will try to answer questions which have gone unanswered for some weeks. An initial attempt to use it more widely proved very unpopular because so many wrong and misleading answers were provided. The bots are inherently limited by their access to copyrighted material so any product will need access to all the documentation as a minimum, for training, but also to the wider knowledge base of experience which is not in the documentation and some of it simply isn't documented anywhere. That's where the hands-on experience of community members can make the real difference. Moreover, what we often see is that these posts are not even actually intended to be helpful, just to look like they are real answers. Then the user comes back a day or 2 later to edit and add SPAM links to all the posts. So genuine and well intentioned answers are always welcome, fake answers are not.

Yah, thats probably a good idea :). Ty for the correct table!

This is how AP 2802/3802 signal if power it is not OK after boot and ME it is available, video:

(view in My Videos)

Easy to check from terminal also:

enter command: show logg and search for:

LLDP PoE negotiation START ... LLDP PoE negotiation FAILED !! ... Power mode: Degraded/Reduced Power, power_detection: DC_adapter(FALSE), 802.3AF_POE(TRUE) ... AP is in critical condition ... after some time radio will be disabled... AP is in critical condition Bringing down radio wifi0 Stopped Radio 0 Bringing down radio wifi1 Stopped Radio 1 Slot 0 radio down Slot 1 radio down

p.s.

It look like it is an bug in ME interface and AP it is displayed with radio operational and Power status Power injector / Full Power, even if LED signal, so better to check from terminal also to be sure.
