Cisco Switching/Routing :: POE Devices Not Working As Expected AIR-CAP3502I-A-K9
May 29, 2012
I have 10 new AIR-CAP3502I-A-K9 connected to a WS-C3750X-48PF-L switch. 8 of the APs power on and connect perfectly, but two are problematic. Both devices are granted power, but they never go past the stage of getting power from the switch. A look at POE shows: [code]
Where the AP that is not working is connected to Gi1/0/4. The interface shows down/down. I've tried shutting the interface, removing power, cdp etc.
Are there any other tricks you can think of to get it working or would you say that it's 2 faulty APs? I am not based at site unfortunately so I cannot console to the APs and check them out.

access-list <#> permit/deny <protocol> <sourceAddress> <sourceMask> <destinationAdd> <destinationMask>Say I applied an ACL inbound on Fa0/0, would the source address be the outside the LAN?So if took the same ACL and applied it as outbound, would the source need to be change to an IP inside the LAN?I am a bit confused by the data flow I'm seeing in packet tracer simulation mode to. I set up an ACL for testing purposes "access-list 199 permit ip 193.20.30.0 0.0.0.63 any" set as inbound, the idea being it permits any traffic from the .0 subnet.When I watch the packet in the simulation, it makes it to the destination address then is dropped by the router on it's way back out to the sender.

I have a CSS 11503 with a basic content rule for TCP 10000 going to a few backend servers. I was looking into the default timeout values for flows and when testing using telnet the flow didn't terminate as expected?
For example, i have no 'timeout multiplier' specified in the config and when i look at the output of 'show flow-timeout default' it tells me the default 16 seconds timeout is in effect for *. With that in mind, i telnet to the content rule vip on TCP 10000 and on the backend server using wireshark i can see the TCP threeway handshake. With no data passing i'd expect the CSS to terminate this flow after 16 seconds.. yet it takes exactly 128 seconds before wireshark shows the RST and the flow is terminated. 128 being 8 times the default 16 second flow timeout.
If i try to force the connection to close early by specifiying 'flow-timeout-multiplier 2' in the content rule, or even a multiplier of 40, it still waits 128 seconds to close the telnet connection.

I'm trying to test such 802.1x wired environment:windows xp sp3 as supplicant windows NPS as radius server 2960 as authenticator latest anyconnect (3.1.01065) + nam and standalone profile editor.I have a question: What is the difference between protected identity pattern and unprotected identity pattern (set in nam profile editor)? As I understand documentation PEAP-MSCHAPv2 is a tunneled method and it uses un- protected identity pattern to protect user's identity during phase 0. But if I use any fake identity here (anonymous, anonymous@[domain], etc) access is rejected (Access-Reject in switch debugs). I have to use exacly the same pattern in unprotected identity pattern as in protected identity pattern ([username] or [username]@[domain]) to gain access, regardless of authenticaton mode (same in machine only, user only authentication).

I got 10 Catalysts 3750 (all of them identical) and I got the IOS Update. Anyway I only have service contract for 4 of them.
Am I allowed to update all of them? Or only the four devices which have the service contract?

My question is if I do not want to purchase any additional switches can I connect the devices to the 6509 and put them in their own separate vlans?I am a little fuzzy about the physical connections needed to make this design work as it is.

I have several cabinets with top-of-rack N2K's attached to N5K's via FEX's. 9 cabinets with 2 switches each.
Recently I added 3 more cabinets to the mix, for a total of 12 cabinets with 2 switches each.
I can get into the new switches and see the FEX's and configure ports, etc. but no device I attach to the 'new' N2K's is pingable over the network. I can take the same device, same cable, and attach it to a legacy N2K talking to the same N5K's, and it immediately joins and is pingable over the network

I'm getting currently installing a full Valcom IP sound and clock system , along with all new Cisco 2960 gig ps-l switches. All devices run off of POE. In the past, I have read that most AP's only draw approx. 12.5 watts (va's). But you must take into account length of wire to add your additional draw which puts you at the 14.5 they auto draw. My question being that the clocks I have auto draw 15.4 watts, which is eating up my 370w of power on my switches. The spec sheet on the clocks show only a power consumption of 4.5 watts. So today I turned a few ports down to 4.5 watts and everything still worked fine.. Any experience by chance with Valcom devices or just turning the power down on devices in general? I can imagine that a clock is drawing enough to care about the length of the wire run.

Has come across issues with multiple GRE tunnels between two devices when using the same source and destination addresses. I've tried using tunnel keys but this makes no difference. The only way I can get this to work is between different source & destination addresses.

I just upgraded to the e4200 v2 and I seem to be having connection issues with my android phone and tablet. Both are 802.11n compatable but they seem to have issues staying connected. Just so everyone is up to speed, there are two connections made by android, a general one to the internet, and a second one to the google servers (for syncing e-mail and contacts and the like) When just connected to the internet, the wireless icons are gray, when connected to the google servers as well, the icons turn blue. It's the drop in connection to the google servers that I'm having an issue with. I currently have the router set in full auto for channel and frequency band, but I've also tried setting specific ones thinking maybe the change in channel or something was causing the disconnect. The disconnect will even happen when I'm sitting right next to the router. The phone is a Samsung Galaxy Nexus (Verizon LTE) running Android 4.0.3 and a Asus Transformer tablet (Wifi only) running android 3.2.1.

In my organization we have several 2950T that conected each other. We have 4 floor with each floor have 1 sw except 4th flr have 3 sw.
Main server, apps, db ( 15 units) connected to core sw at 4th flr. Currently the problem is others devices can't connected to the server at core sw. Test ping and the network to core sw is intermittent problem. When ping 100 times only 30 reply. After 10 minutes the connection restored. Ping 100 times successful. It will not having problem again until the next day. This already happen 3 days. Any command for me to use to check if port or the switch having problem? Any log i can collect

I have a Cisco 887M router which I wish to restrict the devices allowed to be connected/allocated an IP address to two, and *only* two.
I can't, for the life of me, find out how to allow these two devices to connect to ANY port - I can configure a MAC restriction on a single port, but I don't know how to make it so that I can allow JUST these two devices to connect to any port in the 4 port switch/VLAN (VLAN 1 is used because the mongrel who set this up was lazy). I know the MAC addresses I want to allow
How I can do this? I *can* restrict any given port to the two MAC addresses - but if I try to add the MAC addresses to another port, they get removed from the initial one. I need to be able to have them connect to ANY port and work, but allow NOTHING else to work.
For those wondering, this is to counter a user who is utilising company resources for purposes not approved - and costing us quite a bit of money in the process.

We just installed a Cisco ME-3400EG switch at one of our sites. A Cisco C3750X switch is connected to the 3400. When we run the command CDP NEIGHBORS, the 3400 shows no devices. We can access the 3750 via the 3400. Also, when we run CDP NEIGHBORS on the 3750 we do not see the 3400 (but other devices are displayed). How can we get CDP to display the devices on the 3400? We have already tryed CDP RUN.

I have a network that has a pair of 6500 switches on either end, running HSRP. In between each 6500 are two to three ruggedcom switches. They are connected to each other and the 6500's by trunk ports in a straight line. The 6500's see each other as CDP neighbors, and the 6500's can see the rugged- com as LLDP neighbors (ruggedcom only supports LLDP).
The issue is that randomly devices on the ruggedcoms will drop offline and then come back. The problem is that the devices that drop offline are all in the same VLAN, so it appears like a virus - i.e. one device drops off, then multiple. Eventually the HSRP starts flapping between the two 6500s and this causes havoc on the network.I'm almost to the point of taking a laptop and plugging it into one of the ruggedcom's to see traffic, but the issue is that the ruggedcoms are outside in cabinets that laptops shouldnt be exposed to.

show cdp neighbors command shows two devices connected through the same local port?I have a Cisco 3560 that when I issue the "show cdp neighbors" command I get the following results: [code]
the question is why is this showing that Gig0/3 is being used twice to connect to two different devices. I have verified there is no hub connected to this port and in fact Switch3 is not connected to Switch1 at all yet it still shows up in the CDP table.
I have cleared the CDP table on every device at this location and still get the same results.

This summer the IT department at my location rolled out a little more than 100 AIR-CAP3502I-A-K9's to much success. We have had an issue with only one AP. This paticular AP must have gotten unplugged during the updating process after the initial conneciton to the controller was made as the LED currently blinks red-blue-red, indicating an error in the flash memory according to the manual.

I am doing some really rough budget numbers. What can I expect for a life cycle on some Cisco gear like a 2801 router and a 48 port PoE switch? Is 4 years pushing it too much? We usually don't upgrade unless something breaks.

In my LAN environment, I'm using two cisco SG300-10 switches. Both switches are connected by GE10 on both switches, where both ports are set to trunk.Now on all ports 1-9 on both switches, I'm having client computers attached. So I set ports 1-9 to "access" mode.All interfaces on any switch is left in default vlan.
Is it normal that I see all traffic from all connected devices on any port where I connect a listening device?What I'd like to achieve is, that only traffic that is meant for a specific workstation is actually forwarded to this workstation. By now it seems that I get all the traffic from everybody.

I have 1 cisco AP (CAP3502I) which is not able to associate with WLC (version 7.0.235.0), using CAPWAP. Simply from debug I can see that AP is trying to contact WLC on port udp/5246 but can't see any response from WLC.
*Oct 19 07:06:50.055: UDP: sent src=x.x.x.x(4271), dst=wlc.wlc.wlc.wcl(5246), length=47
AP is getting config about WLC from DHCP option 43 and have own reservation to get same IP address (+default GW). AP is NOT associated but as it has IP address from DHCP then it is pingable. But don't know why, but I'm not able to tracert/traceroute to this AP, as I can see it is getting packets but it is not responding.
But on different locations, where are same APs model (associated with WLC) I have no problem with traceroute it, as APs are responding.
My question: It is not related that AP is not able to associate with WLC (still working on it) BUT should I be able to traceroute/tracert to unassociated AP (to his IP) and get response???
NOTE:
==> WLC is in DC and AP on one location, so diagram could be: WLC ---- L3 device ---- Provider MPLS router..........Provider MPLS router ---- L3 device -- L2 switch --- AP (CAPWAP)
@It means that there is NO FW on tha way :-)
I check many other APs with same model and non of them has problem to respond for traceroute, but this particular unassociated one has :-
