Cisco :: LWAP Does Not Work On 3750?
May 12, 2011
To lay it out, I recently installed 4 of these in a new office space. We have them connected to a 3750 stack....
Switch Ports Model SW Version SW Image
------ ----- ----- ---------- ----------
* 1 54 WS-C3750X-48P 12.2(53)SE2 C3750E-UNIVERSALK9-M
2 54 WS-C3750X-48P 12.2(53)SE2 C3750E-UNIVERSALK9-M
3 52 WS-C3750-48P 12.2(53)SE2 C3750-IPBASEK9-M
[Code].....
as you may notice, port f5/0/36 is showing not conencted. This is the case even if I move this LWAP to one of the other 3 ports that are working or even a port on one of the other 3 switch models in the stack. I troubleshot without cross connects, I changed port configs, I changed cables, but I still do not get a link. The LWAP does get power though and will start to boot, but then the status light on the top will just blink orange. sounds like the LWAP is broken.. BUT - if I move this LWAP to a port on a 6513, it connects to the switch and links to the WLC just fine.

I am attempting to get a NAT connection to work through a Sonicwall TZ200 to a VLAN defined on a Cisco 3750 switch. So far I have not been able to get it to work. I am able from the VLAN to access the internet and devices on another VLAN.
I have reviewed the configuration of the Sonicwall with Sonicwall support. They checked and see no issue with the configuration. I have the NAT gateway set to the vlan gateway IP address.
Are there any particular configuration options that I need to set on the 3750 switch in order to be able to route the traffic from the internet to the VLAN?

I've been use to managing our ASA's on firmware 8.2, however we have got a couple of ASA's on firmware 8.4 for a new project and the NAT area especially in the ASDM is very different now, I feel like I know nothing. On these new ASA's on 8.4 that will be in active/standy mode I will be creating a sub interfaces off these by attaching a 3750 and I wondered how the NAT exempts will work.
I will have to use exempts as I don't want the source IP to change when going from one interface to another in certain situations and this setup described works well on 8.2, but how can I do this on 8.4 as I don't even see the option for creating NAT exempts, looks like a different world?

I have PC_A and PC_B connected to the same switch, and are put in the same vlan. PC_A is the master (source) and PC_B is the destination (client). IGMP Snooping is enabled by default.
Is there any reason why this should fail? There is no RP or any interface with PIM enabled. Its a flat network with a source and client in the same vlan...
IH-3750-LOADTEST-101#show ip igmp snooping vlan 724
Global IGMP Snooping configuration:

IGMP snooping : Enabled

I have 2 local accounts on a 3750 that kick in should radius be unavailable. If I log in as the admin account it gets priv 15, if I log in as the other user it gets privilege 3 which is correct, by my commands dont work, this is what I have added and the strange thing is I've dont this many times before on our other switches
username admin privilege 15 secret ***
username users privilege 3 secret ***

I have a 3750-48P when plugged in has fans that spin up, but no lights on the front of the chassis. Does this mean the power supply is bad? If its bad, why do the fans power up? Also, i am not receiving any data through the console.

We're in the process of upgrading our Wireless AP's from autonomus to LWAP. We're doing the upgrades remotely (we have 100's of sites to do, and it's not possible to be there to console on to each one), using a local computer to upgrade them to LWAP's with the Cisco Upgrade Tool.Having some inconsistent bugs pop up though from time to time.The most common one is that it basically buggers up the IP address after applying the recovery firmware image. It's supposed to keep the IP it had according to the IPFile.txt (for example 172.25.25.4), but it does something very weird... it keeps the last two octets (so 25.4 from the e.g) but replaces the first two octets with a 192.168 address. So the final address in this example after the UpgradeTool has done its work, is 192.168.25.4 - which is compeltely wrong.
This causes it to be unable to talk to the WLC (obviously, with bogus IP information it will struggle), and gives us big problems in that it wont ever come up unless someone can console to the AP and fix it. We can usually resolve the issue by munging about on the switch - switching the port it's connected to between access and trunk and doing some shut/noshut cycles seems to do the trick mostly.

I have an AIR-AP1242AG-E-K9 which had c1240-k9w8-mx.124-21a.JA loaded, I followed the link below and upgraded with Cisco’s upgrade tool to c1240-rcvk9w8-mx with no problems at all, after the upgrade I could then see the LWAP on the 4402 controller and had it working a treat.Now the problems begin, I brought it into the office where we have 5508 controllers, plug in the LWAP into our management switch and boot it up I get an IP assigned from the DHCP server and the AP goes into discovery mode but never finds the controller.I have logged the boot process but this does not give much away, our other 1100 series AP’s boot fine,
[URL]
Console Boot Log.
Xmodem file system is available.
flashfs[0]: 9 files, 3 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 15998976
[code]....
And that is where she sits and does nothing more, I have noticed the DNS problems but the other 1100 series LWAP’s boot up after show that same issue.

Is it possible to Change IOS of 1252 LWAP AP to Autonomous AP? I have seen some documents for changing Autonomous AP to LWAP and change back procedures.

We are deploying a new wireless infrastructure with a WCS (7.0.172.0) / WLC (7.0.116.0) and AP AIR-LAP1142N-E-K9This AP are in lightweight mode.I know that we cannot do a SNMP polling directly on the AP.For the moment we monitor the AP's only by the traps sent by the WLC.
Is it possible to poll continuously the AP's status (up/down) maybe through the WLC or the WCS ? if yes how we can do that ?The goal is to monitor all the network with only one tool (HPOV) and the AP's integrated on our supervision map.

I have a 1121 autonomous AP which I switched to the lightweight mode by copying the LWAPP ios to its flash and issuing the command boot system flash IOS_file_Name. After that I was unable to associate the AP to my wireless controller because it was continiously rebooting. Unfortunately this AP does not have a console port so I can access the debug and see what is happening. And I was not able to switch it back to the autonmous mode becaus the AP won't accept the Autonomous mode IOS anymore.

I would like to convert some 1142N LAP to Autonomous. Is there a way to do ?
I have noticed a new image : c1140-k9w7-tar.124-25d.JA.tar
I don't see a way to replace the image in flash ?

I have an environment of Cisco 5508 Wireless Controller and 1142N Access Points. I have a problem with the ratio of concentration of clients connecting to Access points in floors.
Recently I have been turning off 802.11a on the access points and I am seeing increase in client count in a few of acces points.What is the maximum client count supported by these access points and how do i ensure they are distributed evenly on access points?

I have a 3502 AP that I am attempting to set back to factory default including clearing the username and password. It is going to work off of 4400 controllers. I have read numerous documents no how to clear the config and password but so far nothing has worked. I can get it into ap: mode but not sure what to enter here. When I do a dir there doesnt seem to be any files. It will pull an IP address via the local router but cannot communicate with WLC.

I am installing a small wireless network (for the firs time). The WLAN is connected to a router/firewall and consists of a Cisco 2960-C Series 8-Port Compact Ethernet Switch, a Cisco Aironet 2500 Series Wireless LAN Controller for Lightweight Access Points and a Cisco Aironet 1140 Series g/n Lightweight Access Points (five AP if I get it to work).
My problem is that when a client connects to the access point it does not get an IP-address.
In the WLC DHCP proxy is enabled and Internal DHCP server is used.
The scope is from 192.168.104.65 - 192.168.104.99
The WLC IP is 192.168.104.60
The DHCP server is given as 192.168.104.60
When starting the system I can see the the AP have the IP 192.168.104.66 so it seems the DHCP gives out IP-addresses. I can ping the AP.
When a client connects to the APit is asked for the security key and the client can be seen in the WLC monitor section. The client never gets an IP-address; in the WLC monitor 0.0.0.0 is shown.

We have WLC 4402 and LWAP 1510In access control list menu, all needed rule added and the last rule deny any to any We use Ethernet bridging on LWAP and some clients connect with wire network that associated with Ethernet bridge LWAP, Now when deny rule applied the client that connect with wired network couldn't established VPN connection or another service to the routing and remote server, I create rule that permit any to routing and remote server.

I am running big wireless network, with 20no of 5500 with 7.0.116.0 version. I have more than 20,000 AP's. If i add some config in primary controller or do some changes or reboot all the AP's are moving to backup controller. this doesn’t have any problem, but many AP's which moved to backup controller are losing VLAN mapping. This happens every time. Primary --> backup, backup --> primary. Both controllers have same vern...same config etc..

I have a problem with three AIR-LAP1131AG-E-K9 that joined the controller and the status led turns to yellow after joining the controller while other LEDs are blinking green.The APs has no coverage at all although the WCS shows that there is coverage and the 4400WLC shows that the AP interfaces are UP. (The ethernet interface and tha 802.11b,g radio interface is up).The SSID broadcast is enabled.On the switch the interface is up and there is traffic going in and out of the LAP.I tired power reset and factory reset for the APs but the problem remains the same.

We have just installed our first CT2504.After install I have found a dramatic drop in signal strength compared to the wireless survey result obtained.All of our site surveys include real world testing using an AP, in this case a AP1041N.In doubt I retested a section using an AP1041N in the same location as one of the recently deployed LAP1041N.
In the same location a LAP1041N has between -10 and -20dbi difference in SNR compared to the test AP1041N.For example locations that tested with -60dbi using an AP1041N have little to no coverage using the LAP1041N installed.This applies irrespective of the WLC automatic control over Tx power or manually setting the LAP TX to the highest level.

I have two Windows 7 computers and neither one will successfully upgrade a 1242 AP to LWAP. However, I go to a coworker's XP machine and run the tool without issues. On Windows 7 I keep receiving the error message of ACL or Firewall is blocking. I have added rules and then even tried disabling the firewalls completely on both computers and still no success.

I'm looking at adding a Cisco 3750-X switch running c3750e-universalk9-mz.122-55.SE1 (IP base license) into a stack of 3750-G switches running c3750-ipbasek9-mz.122-55.SE1.bin Given that the version and feature sets are the same I don't forsee any compatibility issues. Would there be any reason why a universal image wouldn't stack correctly with other switches running the single .bin file?

We have a stack of switches that is at the max number of members allowed in the stack. Problem is we are running out of port density and need to add more ports. So instead of adding a whole new stack I would rather replace 2 of the 24-port swicthes with 48-port switches.
If the two 24-port swicthes we are removing are stack members and neither of them are the stack master, I should be able to replace the 24-port switches with the 48-port switches without bringing the master offline? If the new 48-port switches are running the same IOS version as the current 24-port swicthes, they should add themselves to the stack?Would I have to tell the new 48-port swicthes what switch numbers they are replacing in order for them to be added to the stack since we are at the max number of members?Also since the 48-port swicthes are replacing 24-port switches will the master give the 48-port switches the configuration for only the 24-ports?

I have a DIR-655 B1 router. The firmware is 2.00 NA. Just to clarify, the DSi itself does work with WPA, but the games only work with WEP. I made a guest account and set it to WEP and it still does not work. I have tried making the main connection WEP as well, but when I go on the game and try it, it says it is WPA and not WEP. My friend has a DIR-655 as well, but the hardware and firmware version are different. Her games work flawlessly.
