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.

Re: Difference between HWIC-1FE and HWIC-4ESW
Hi
I am trying to find out the main difference between the HWIC-1FE and HWIC-4ESW cards.
Also I have a cisco 2811 router that is configured with one Fastethernet connected to DSL and the other port connects to mt LAN and METRO (using subinterfaces), is this the best practice?HWIC-4ESW is the 4-port single-wide 10/100BaseT Ethernet switch HWIC. The 4ESW is a L2 switch and is cost effective.
HWIC-1FE is 1-port Fast Ethernet HWIC. The HWIC-1FE is a true L3 interface and is expensive. It has feature parity with an onboard FE interface except for OAM support, which is delayed.
HWIC-4ESW has the capability to setup VLAN but they are not the routed ports Whereas, HWIC-1FE has the same characteristics as Onboard FE ports. -

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
WisitHi,
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

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 replyTo 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.

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.

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.

Cisco 4900M integrated X2 ports, CVR-X2-SFP10G and SFP-10G-SR
Hi,
We are going to order two(2) cisco 4900M switches for core and twelve (12) 2960S switches for access (4 stacks with 3 switches each), connected to the core with 10G MM optical paths (up to 300M each). In addition I have one gigabit half-card but it is not related to my questions here. Please see my attached diagram.
So my questions are:
1. Point 1.Can we use integrated eight X2 ports of every of the both 4900M switches as plugging into four of them four convertors CVR-X2-SFP10G and to plug on every of the convertors sfp tranceivers SFP-10G-SR - as it is described on the diagram, or I need for something more in addition to described? I found only some minimum soft releases to use as requirement to use these convertors and sfp tranceivers, but is there something additional I need?
Note:I'm asking that because Dynamic Conf Tool doesn't give me to do such configuration, actually these convertors and SFPs are missing there at all, but it sometimes happens with some products... In documentation it is described this should work (if I didn't pass something which is my main consern and why I'm asking here).
2.Point 3.If this shouldn't work, the other alternative (not described in my diagram) is to use X2-10GB-SR modules without any SFPs - just ot use SC connectors for the optical cables instead of LC. So my question in that case is will 10G links work between X2-10GB-SR at one side and SFP-10G-SR at the other side where I have 2960S switches and this is the only option? Is is expected to have some problems in that scenario?
Note:Actually if Point 1 is workable I prefer to use it instead of Point 2 because of minor price optimization when using SFPs with convertors in comparisson to X2-10GB-SR.
3. If the both variants are possible, which one is preffered and why, what advantages does it have (for example low latency of something else)?
Thank You in Advance
AsenJust for your information, a fiber link does not care if one end of the fiber has an GBIC (SC-type connector) and the other end has a SFP (LC-type of connector); or any other transceiver footprint (X2, CFP, etc.).. The thing that is important is that each module is the same specification, and matches the fiber type and link length of the network (10GBASE-SX in this example).
Good luck. -
I updated iTunes to 10.4 version and now it doesn't start and send a messages "iTunes has detected an error and must be closed". Someone have the same problem and how can we repair our installation insted of change the windows XP installation? Best regards
Only way to get iMac starting again was to re-install 10.4.4 from DVD, and then update it into 10.4.6. For a while it worked perfectly, just as before.
Then I tried to print to CD with my EPSON Stylus Photo 950 from Adobe Photoshop Elements (2.0). It didn't print anything, but printer started flashing all lights. The print job was not performed, so I did remove it from the Printer Utility. After that the iMac started "ticking" again, same noise than before, after 10.4.7 installation. I did re-boot iMac. It never started, it does stuck on gray screen (gray block running clockwise). HW test from DVD didn't find any problems (extended search looping 3 times). But Disk Utility found hard drive to have inaccurate node structure, it could not fix it.
Apple support recommended to use DiskWarrior. However, it does not support (yet) Intel Macs. I haven't got TechTool Pro 4.5.1 anywhere. iMac does start on to FireWire mode (T at boot), but I cannot see the disk from 10.2.8 iMac.
So, obvisously the problem is not 10.4.7. I believe it to be ESPON printer driver compatibility on Mac OSX. This does not suprise me, EPSON printers *****, I shall never purchase one again. However, disk catalog structure should not get messed by one faulty printer driver! -
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,

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 !!

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.

Will on-board Gigabit Ethernet ports on a Cisco 3845 support a 100 Mb SFP?
Hi,
This is a very specific question - hopefully someone has tested this or run into this scenario...
I was trying to connect a Cisco 3845 router to a 100 Mbps circuit. Specifically, I was trying to connect this circuit to the on-board Gigabit Ethernet port (Gig 0/0). This is the port that can be used as either an RJ45 or SFP slot. The only SFP I had was a multi-mode 100 Mbps SFP. When I hooked it up to Gi0/0, I got a message saying the SFP type wasn't supported on the chassis.
I was able to deploy the 3845 and since then I haven't had the correct hardware to recreate the exact scenario. Has anyone experienced this? Is it simply because Gigabit interface on a 3845 won't support a Fast Ethernet (100 Mbps) SFP?
Thanks.Not all SFP's will just plug in and work. Here are the SFP's that are considered compatible with the 3800 series ISR's.
