I have a lightweight AP that boots into RoMmon, if i hold the reset button in for 10 seconds or so it will boot into the IOS and download the config from the controller but never registers. then once i reboot it it goes back to Romon unless i hold in the button again.

I have an 887VA-K9 which boots into ROMMON mode every time. It seems to have 3 tries at booting, then fails.
The entire console output from power-on is (blank lines removed):

we have 55 of the 1841 routers here, and one of them always boots to ROMMON from a very cold (down 1 hour or more) start. The image on all 55 is c1841-ipbasek9-mz.124-24.T4.bin. 32 MB Cisco brand flash. Here's what's been done thus far:In ROMMON changed to 0x2102. Then 'reset' and the image boots fine. Change config-reg to 0x2102. Save config. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Boot from ROMMON to USBflash0: Format the CF then copy over the bin file. Change to 0x2102 and save. Reload and image boots fine again. Wait an hour or more and boots to ROMMON.Swapped CF with another unit. Again, works fine to reload, but shut down and restart an hour or more later and boots to ROMMON. Format this CF and copy over image while on router. Image boots fine. Wait an hour or more and boots to ROMMON.In each case of very cold start the configuration register has reverted to 0x0 {why it boots to ROMMON}Tried dx mode with 0x8001. Nothing seen that is unusual to me, but I'm not an expert by any means.It doesn't seem to a CF card problem, but could be a connection to the CF card and then something behind that.
Here is the output of diagnostic boot mode:

Got a long lingering, year long issue that has spanned about 8 supervisor cards and a complete chassis swap. The 6509 acts as a ITN in our facility. The active sup card at random points of pipe usage boots into rommon mode, seriously inhibiting our company. I'm able to swap the 2 fiber pairs that we had going into the active supervisor card into the secondary and usually this works for another random amount of time, however, today it occured within minutes of hooking up the fiber links. Sitting there for about 5 minutes it booted into ROMMON. When this happens, I'm able to boot the sup card back to good status. Previous remedial actions, other than replacing sup cards/chassis, was checking the config register and making sure it was x2102. Previously, it was not, and we corrected and reloaded and it took, we thought this would fix the problem, until today.

I'm fairly new to networking and need to migrate an old core to a new core. I have a 6509-e Switch that I had an RMA on one of my 720 sup cards. After receiving the sup card I swapped my slave out with the new one, expecting it to boot into ios. It booted into Roman. I tried to boot the image manually and it did the same thing. I also tried to boot from my flash and, again, booted into ROMmon.
Question: If i configure and change the boot to boot from image it tells me i need to reset or power cycle first. Will this reset the entire switch? As this is production I'd rather not.
I am at home now, but I can supply any logs/hardware model/configs tomorrow. I thought I would see if this is an easy fix.
I'm finding some odd information from Cisco pages and non-Cisco pages also. What is the correct syntax for specifying boot images on a flash:/ of a switch? The differences is if you need the "/" or not as well as after the ";" fo you need to specify flash again.

View 4 Replies View Relatedwe want to have full wireless coverage in a big warehouse (120mx90m) and 15 meter Height that will be having big racks (14 meters height) and 2 meter between the racks and the rack itself is 1.5 meter (2 rack back to back), now we will be having scanners and we need to make sure the wireless is covering everywhere.Where is the best place to put the AP, Ceiling? How Many APs per row ? each row will be around 60 meters length.
Is AP 1252 a good choice? The scanners are a/b/g.What i'm thinking of is to put 1 AP per row mounted on the ceiling and antennas facing down because it is hard to mount the APs between the rack because of the automated racking system.
Currently my company has 1 primary SSID that is used throughout both floors of the building. We have 1252 LAPs which have 2.4 and 5Ghz antennas. I'm not sure if this issue is only with XP or perhaps it's the computer's drivers but we run into problems with end users going to a different location and having a very weak signal or nothing at all, yet coverage is fine. I believe the problem is the end user's machine selecting the strongest signal and it I have the feeling that switching bands isn't being done as it should when it's in range. So my question,
Should I split up our 1 SSID and created multiple SSIDs according to the location and include 5Ghz or 2.4Ghz in the SSID name so it's easier to ensure that users are connected to the proper signal? I want to ask if multiple SSIDs would still enable users to freely roam (as long as the ssids are configured) throughout the building without noticing a loss of signal but currently just having 1 SSID isn't really enabling people to freely roam around without connection issues.I don't believe having multiple SSIDs will be useful for the computer's choose their connection any more efficiently but allowing the user to manually see what they're connected to and pick something better according to their location.
I am configuring a mobile van that is used for a mobile health clinic to drive to several locations and when pulling into an allocated parking spot the van will connect via wireless automatically. I am using autonomous 1252 AP's and am considering either briding or workgroup bridging.
The issue I am encountering is that the AP inside a van is a router that has to do DHCP across the wireless and because the ethernet interface between router and AP in the van never goes down the router does not know to re-DHCP. I remember from way back there was an IOS command to track a serial interface and drop the ethernet if the serial link goes down. Is there an equivalent command for AP's to drop the ethernet interface if the radio interfaces go down?
I am using two Cisco Aironet 1252 (cisco AIR-AP1252AG-A-K9) to setup a point to point link (one is configured as root bridge and is as a non-root bridge). Both Aironets are running software version Version 12.4(25d)JA.
Is there a way that I can that I can perform an antenna alignment test on the Aironet that is configured as a non-root bridge?executing the following command dot11 dot11radio 0 ? does not show the antenna-alignemnet option.
I would like to add an additional antenna to a 1252 LAP but I'm unsure of a few things...
I know this LAP currently has at least a yogi directional antenna (AIR-ANT2410Y-R) and also a ( AIR-ANT2485P-R) connected to it. The access point is in a ceiling so I cannot view the connections but according to this data sheet, { URL } each of the antennas I've specified require 3 per AP. I am only aware of 1 of each being used so not sure why 3 would be required?
Also on my 1252 1 side has 3, 2.4Ghz connections for antennas, TX, TX&RX, and RX. If I want to only use 1 AIR-ANT2410Y-R, would this be connected to the TX&RX port? Do all antennas support transmit and receive or are there some that only support TX and others that only support RX or is this based only how you configure the antennas? On the other side of the access point there are 3, 5Ghz antenna connections.
I found a few older forum posts and documents online discussing how to create multiple SSIDs on 1 1252 AP using the WLC and they state that VLANs are needed for the interface and then I've read that multiple SSIDs on 1 interface are also possible. I'm not sure on how to actually configure this. I would like my 2.4Ghz radio on the 1252 to be associated with the current SSID in production and the 5Ghz band associated with another SSID that's in production. I couldn't find an option in the WLC or anything stated in the documents I've read about how to associate the radio band with the SSID.
View 5 Replies View RelatedWe are using WiSM WLCs and WCS to control a variety of 1131,1142 and 1252 APs utilising AP groups.
I've noticed on WCS that the power of certain APs is at a low setting, even though the APs surrounding them are also at a low setting. This is causing some gaps to appear on the heatmaps. I was under the impression that the WLCs would regulate the AP power to compensate for any gaps. Currently the global TX power level assignment method algorithm is set to automatic every 600 sec.
Now, obviously I could change this to fixed (not ideal as I may not want all my APs to run at max power all the time) or to on demand (also not ideal due to the increased admin).
Is there a way I can verify that the automatic power levels are adjusting as they should? Why are there gaps appearing in my heatmaps?
*NB It's not just the gaps on the heatmaps, I'm getting reports of dropping wireless signals from users hence me looking at the heatmaps and they just happen to correspond.

how to restore my IOS on this device
I have two 1252s on ports 1 and 2 off a Catalyst 3550. No other device on the switch except the fiber uplink.
Initially 1252 #2 (on port 2) resets for no reason at no specific time. We did not have a problem with 1252 #1.
The show ver on #2 does indicate that equipment resets due to power. I figured the 3550 is having problems powering two 1252s so had this AP on PWRINJ4 (validated its not drawing power via show power inline).
Today, #2 does not reset. However, now #1, which is the only device using inline power is now resetting. Same thing, reset due to power. Same weird behavior, at no particular time.
I've also have "no cdp enable" out off each port as i understand CDP sometime cause device to not boot up (15w versus 15.4w issue).
Both AP btw are Standalone IOS.
I have three Autonomous AP´s in a small office running voice applications, all of them are connected to the same infrastructure switch and they have same configuration, voice Vlan is configure to open authentication. I have two models of AP 1252 and 1262 and I paste Radio configuration below.
First issue: During calls users are facing problems when roaming between AP´s, and eventually calls are dropped.
Second issue: Sometimes one of these AP´s(1252) lose all transmit signal and when return I got authentication error on log.
Recently we had a situation where our users were unplugging one of our un-mounted 1252 LAPs. They would do this so they could borrow the wire to direct connect any one of their devices not realizing they were disconnecting a wireless access point. After discovering that the AP was unplugged once again, our admin plugged the AP back to the network but noticed that it no longer would connect to the controller. We can no longer console into the AP but can console into all other APs we have. All 3 lights are now green. Radio and Ethernet are solid and Status is blinking. I found the Cisco doc explaining the meaning of the front panel lights but have not found this particular configuration. What these lights mean and why not being able to use the console port?

As one AP can server 25 users, 2 APs are placed with antenna directions facing the compact users. Each users gets very good signal from these two APs.
Whether there will be serious interference and client association issues in this scenario? once one AP associates 25 clients, whether other 25 clients associate completely to other AP?
