Hello Nagarajan,
looking at the data sheet (see link below) it appears that the WIC-1B-S/T is not supported on the 3845, you need the WIC-1B-S/T-V3, as well as IOS 12.3(11)T...

Cisco 3845 - Enable bluetooth but cucm administration not loading

Hello Guys,
I am trying to enable Jabra bluetooth on Cisco 3845 for a 7962g phone and I am trying to access cucm page and I am unable to do it. I need some help from you guys. Page gives Http error 404, Apache Tomcat. Not sure where to start troubleshooting.
We have Cisco 3845 and Cisco Unity Express 8.6.1 installed.

Hi p.bevilacqua
Thank you for this info I actually tried all those options aswell but still no luck.. could it be a IOS or DSP issue ?
in The meantime I have forwarded this link on to the 3rd partyCisco (Call manager) provider aswell.

IPhone 6 is not recognized by AT&T Microcell (older Cisco version)

I just discovered my new iPhone 6 is not connecting to my existing home AT&T Microcell. This device worked just fine for the last three years with my old iPhones 4 & 5. AT&T tech support had no immediate solution. (The Voice-over-WiFi feature should resolve this issue at some point in the future, however.)

Hello Myschyveus,
Thanks for using Apple Support Communities.
To troubleshoot this issue where your iPhone is not being recognized by iPhoto please follow the steps in the article below for your computer.

Cisco 3845 didn't detect HWIC-1FE and SFP GLC-LHSM

Cisco 3845 not detect HWIC-1FE and
SFP GLC-LHSM.
What is latest IOS which will detect WIC HWIC-1FE , SFP GLC-LH-SM.

Hi,
You need a minimum of 12.4(15)T for HWIC-1FE Support on 3845 routers.
Please refer the below URL for details:
http://www.cisco.com/en/US/prod/collateral/routers/ps5854/product_data_sheet0900aecd80581fe6_ps5853_Products_Data_Sheet.html
For the HWIC-1FE and HWIC-2FE the minimum level is Cisco IOS 12.4(15)T.

Does Cisco 3845 with NM-16A/S support OIR feature or Hot swap for this NM.

Dear Sir
My customer would like to implement Cisco 3845 with NM-16A/S x 4. I found that Cisco 3845 support OIR function but I am not sure OIR function that Cisco 3845 support, it support with which NM models. Can anyone tell me that NM-16A/S on Cisco 3845 support OIR function on this NM or not.
Thank you very much

Hi,
From what I have read from the following document.
http://www.cisco.com/en/US/products/ps5855/products_installation_guide_chapter09186a00802ccf1d.html
Network Modules
Network modules install directly into slots in the rear of the router. The Cisco 3845 router supports online insertion and removal (OIR, or hot swap) of network modules. The Cisco 3825 router does not support OIR.
Caution The Cisco 3845 router supports OIR with similar modules only. If you remove a network module, along with any installed WAN or voice interface cards, install another module and card combination exactly like it.
Interface Cards
Cisco 3800 series routers do not support OIR (hot swap) of interface cards inserted directly into router slots. You must turn off the router before installing or removing an interface card.
The Cisco 3825 router and the Cisco 3845 router each provide four interface card slots, labeled on the rear panel by HWIC and a number. Each slot can be occupied by one single-wide WIC, VIC, VWIC, or HWIC.
Hope this helps

DMVPN issue on a cisco 3845

Hi all,
We have configured a DMVPN from our headquarter to our branch offices (let's say BR1-BR3) .
We have noticed that sometime we cannot access some of our branch office, the scenario is like this:
- sometime, BR1 and BR2 are down but BR3 is working fine
- sometime, BR2 and BR3 are down but BR1 is working fine
- sometime, BR1 and BR3 are down but BR2 is working fine
- sometime, only one branch office is down and others are working fine
the hub is a cisco 3845, the IOS is c3845-advipservicesk9-mz.124-5c.bin
from the log, we have
*Sep 7 11:28:59.260: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 7: Neighbor x.x.x.x (Tunnel100) is down: stuck in active
*Sep 7 11:29:01.052: %DUAL-5-NBRCHANGE: IP-EIGRP(0) 7: Neighbor x.x.x.x (Tunnel100) is up: new adjacency
we do not know why it is down, there is no problem on the connection between the headquarter and branche offices.
Any suggestion are appreciated.

Hi Portu,
please, find below the answer:
Are you able to ping from tunnel interface to tunnel interface?
yes, we are able to ping tunnel interface to tunnel interface
Does the IPsec tunnel come down (show crypto isakmp sa)?
no, we see the status is ACTIVE
Does the tunnel interface come down (show interface tunnel x or show ip interface brief)?
the tunnel is UP
Any ISAKMP / IPsec related logs during the failure?
How often does it happen?
sometimes, many times in one day
sometimes, every 1 or 2 days
Does it recover by itself?
yes, it does
but after rebooting devices, it works fine again
Please, let us know if you need more information.

Problem with L2TP with Cisco 3845

Dear all
I have the following scenario for my dailup network.
MaxTNT(LAC) ---Ethernet--- Cisco3845 (LNS)
I have configuered MaxTNT Dailup server to act as LAC and launch a L2TP Tunnel after authenticating with Radius Server. Cisco 3845 acting as LNS estblishes L2TP tunnel with LAC and Dailup Users get connected on it as VPDNpppOE users.
However problem i am facing is that i don't receieve any authentication request on Cisco LNS. As soon as user gets connect it sents Accouting Request only.
I need authorization request in order to Push various different AVP from radius. But its not happening.
Anyone have any idea what could be wrong here?? is thre any specific parameter i need to set up Cisoc.. or on MaxTNT????
Waiting for reply

To enable the Layer 2 Tunnel Protocol (L2TP) tunnel server or network access server (NAS) to perform remote authentication, authorization, and accounting (AAA) tunnel authentication and authorization, use the vpdn tunnel authorization network command in global configuration mode. To disable remote tunnel authentication and authorization and return to the default of local tunnel authentication and authorization, use the no form of this command.
vpdn tunnel authorization network {list-name | default}
no vpdn tunnel authorization network {list-name | default}

FEX 2232TM not recognized by Nexus 5010P

Hi there,
I don't have any clue what this problem might be so please help.
I have a brandnew FEX 2232TM which is connected to a NEXUS 5010P running the following firmware:
oftware
BIOS:      version 1.5.0
loader:    version N/A
kickstart: version 5.2(1)N1(1)
system:    version 5.2(1)N1(1)
power-seq: Module 1: version v1.2
BIOS compile time:       11/30/10
kickstart image file is: bootflash:///n5000-uk9-kickstart.5.2.1.N1.1.bin
kickstart compile time: 7/12/2012 19:00:00 [07/13/2012 02:08:13]
system image file is:    bootflash:///n5000-uk9.5.2.1.N1.1.bin
system compile time:     7/12/2012 19:00:00 [07/13/2012 03:23:16]
According to the Cisco download page it is the latest version and should definitely support the 2232TM.
The problem is that the FEX is completely not recognized by the parent Nexus.
It is connected via 8 FET modules. But when ich check the light on both sides I only have light on the NEXUS side never on the FEX side on all modules.
From my understanding this should be the root cause of the issue because no light = no link.
I tried standard 10GBase-SR and Twinax cables as well. Same behavior - the FEX is not recognized.
The status LED if of course orange on the FEX.
This is the FEX related config ont he NEXUS:

Can anyone give me a hint what I am missing here??
Any help is really appreciated.
Thanks a lot!

Thanks,

High CPU Usage on Cisco 3845

Hi all,
I'm having high CPU usage with one of my Cisco 3845.
It works as an IP-IP Gateway and the CPU is quite high when the total number of calls only around 100-200 calls.
I check the CPU usage with "show process cpu sort" and it looks like there are some "hidden" processes that consuming CPU.
For example, 41% is total CPU, 25% is due to interrups, so CPU utilization on process level = 41 - 25 = 16%.
But as showed below, processes don't consume that much CPU, only around 7% ???
Please help to advise on this case. Any help is highly appreciated..
Thank you.

Has this been something that just recently started happening, or have you had this issue for a while? Have you installed any new programs recently?
You may want to download Glary Utilities, which is a free software(they will ask you if you want to go Pro, just say no, the free version works very well). There is a module for startup manager. You can go in and disable stuff that starts with the computer. I would advise unchecking adobe, java, quicktime, printers, etc. Anything that doesn't REALLY need to start with the computer. The nice thing with Glary is that you can restart the computer, and if you find that you need one of the programs to start with windows, you can go back in and enable it again.
The Celeron 925 processor in your computer is a decent entry level processor, but if there are too many programs running in the background, it can bog down quick. I would also recommend downloading and running Malwarebytes Anti-malware, to be sure that there is nothing malicous running in the background.

ACL processing in Cisco 3845

Hi,
I would like to know that ACL processing in Cisco 3845 is hardware based or software based?
May I have a list of hardware that support dedicated ASIC for ACL processing?
Thanks and Regards,
Ahmed Shahzad.

Ahmed,
ACL processing is primarily accomplished in hardware, but requires forwarding of some traffic flows to the CPU for software processing. The forwarding rate for software-forwarded traffic is substantially less than for hardware-forwarded traffic. When traffic flows are both logged and forwarded, forwarding is done by hardware, but logging must be done by software. Because of the difference in packet handling capacity between hardware and software, if the sum of all flows being logged (both permitted flows and denied flows) is of great enough bandwidth, not all of the packets that are forwarded can be logged.
These factors can cause packets to be sent to the CPU:
•Using the log keyword
•Enabling ICMP unreachables
•Hardware reaching its capacity to store ACL configurations
If ACLs cause large numbers of packets to be sent to the CPU, the switch performance can be negatively affected.
Hope to Help !!

SIP over UDP routing in Cisco 3845

dear friends,
How can we configure the SIP over UDP protocol by Cisco 3845 router?
For more details please fine the attachment.

Yes I tried but that is not helpful for me
How can I contact those people (engage a reputable consultant, or Cisco partner)?

Configure Trunk carrying same Vlans on two separate uplinks on Cisco 3845

Hi,
I need to carry 2 vlans(x & y) in a trunk to two separate redundant devices uplinked to Cisco 3845 on Fa1/0 and Fa1/1. I know I can create sub-interfaces on one of the uplink interfaces(i-e Fa1/0) with 2 distinct 802.1q vlans(Fa1/0.x & Fa1/0.y). But is there a way I can carry same vlans(x & y) trunked to my 2nd redundant device uplinked on 3845 from Fa2/0 ? If not then how should I get the 2nd redundant device uplinked to this 3845 router.
Any tips.. ?
Thanks for your help and suggestions.

IF both links are going to the same device then you can create a Layer 3 Etherchannel.

Configuring QoS on Cisco 3845 router for Polycom Video Conferecing

Dear All,
We have implemented a Polycom Video Conferecing solution at our Head Office. Using this we communicate with other branch offices through WAN (2mbps, MPLS).
The problem is that this WAN link is also used for data. When the traffic is high on the link, the voice and the video quality goes down drastically and we experience connection drops.
At the moment we have configured our Polycom box to communicate at 512kbps speed and we would like to reserve it in our WAN link. In case, video conferencing is not happening we would like it to be utilised by other traffic.
Can we configure QoS on our Cisco 3845 router to do this? I'm not a Cisco expert and have pressures from Management to correct this before the next conference.
I have already googled a fair bit but couldn't find something for me.
Could someone please tell me the exact commands that need to be given on our router to achieve this.
I'll be very thankful for this help.
Best Regards.

Hi,
You can use something like the following to guarantee 5122k of bandwidth to your video-conferencing bandwidth but to allow that bandwidth to be used by other traffic when it is not being used for video-conferencing:
class-map VDOConf
match ip dscp af41
policy-map WANPolicy
class VDOConf
bandwidth 512
interface
service-policy output WANPolicy
Note that the above assumes that your video conferencing traffic is being marked to AF41. If that is not the case, you can always match on the IP address of your polycom device using an ACL:
class-map VDOConf
match access-group 101
access-list 101 permit ip .....
Hope that helps - pls rate the post if it does.
