Cisco WAN :: 3845 Upgrade To A Newer Faster Platform
Feb 22, 2011
I've been experiencing a problem with my existing 3845's that may mean I may have to upgrade to a newer faster platform.Currently I have ISP links to 2 providers and run BGP. Each ISP link plugs into a separate 3845 NM-1GE fiber port. Both links are 100Mb ethernet handoff. There is an average of 50 - 60Mbps traversing each link during peak times. I am experiencing a large number of Input errors on both ISP links almost all of the errors are ignored. I opened a TAC case and I'm told that the 3845 can not handle this much traffic along with an ACL on the ISP interface and BGP. TAC engineer tells me that the RX ring of the interface is being overrun and tuning buffers will not make any difference. CPU util never goes above 25%.
I found this "VWIC2-2MFT-G703 1841 - 3845 tied to platform slot density" from Cisco web site, does it mean if Cisco 1841 have two wic slots I can put two VWIC2-2MFT-G703 in this chassis.
When we originally deployed our Cisco Prime NCS and MSE Virtual Appliances, the VMsphere server they were on was not able to assign us the level of resources we requested. We installed the MSE as "LOW" system due to the memory and CPU requirements. It has a 2000 CAS element limit. At the time we were licensed for 1000, so no huge problem.
Now, we purchased a Cisco UCS C240 server to run our Prime NCS and MSE on, which gives us our own environment where we have plenty of resources. I also bought 6000 CAS element licensing.
The catch is, how can I either do a fresh install, using the same UID, on our new UCS server, so that our licensing is still valid when we move the box, or, is it possible to do some sort of platform reinstall or upgrade after moving our original MSE VM guest over to the UCS server? Sadly, I can't even utilize the additional 1000 CAS element licensing at this time because it won't allow me to add the 6000 license and use only 2000, on the LOW appliance. So I've got to get these VM guests moved, but maintain any UID's so that the licensing still works.
Is it possible to disconnect the licensing we have, from the UID, and move it to a different UID?
I have a DI-604 D-link router, is it necessay to upgrade to newer router to get faster access to internet? Upgrade Firmware? I have a PD950 processor with Win XP pro and use it for DAYTRADING streaming data and fast executions.
Is there any physical or technical diferrences between PWR-3845 AC/2 and PWR-3845 AC? We are trying to order replacement parts and wondering if PWR-3845 AC is for one power supply and AC/2 means you get two with one order?

I current have 20 x cisco AP 1142 with WLC 4400 series, I'm looking for newer/latest Cisco AP for expansion. I was looking at Cisco 3500 series but not sure how good/flexible they are when comparing to 1142 and other AP series.
(eth ports routing only) and a layer 2 switch into a cluster of two layer 3 switch clustered. I have looked at Cisco 3550 EMIs with HSRP but I would like to implement based on newer models of Cisco switches.
I have run into a problem replacing an old Linksys BEFVP41 with a SA520. The BEFVP41 had an address on the LAN defined as a DMZ. That address was another router. It is in the same subnet as the local LAN and I am not sure what ports it uses. It is controlled by an outside group and requires much delay and paperwork to change the address. The new SA520 will only support a DMZ if it is in a different subnet than the LAN. Any way to simulate the old DMZ function on the newer router? I have not yet been able to obtain a list of all ports that should go to the second router. Didn't know if there was a way to forward all ports like the old BEFVP41 does by setting a DMZ address.
trying to upgrade home network and found a dual-band 2.4Ghz and 5Ghz router. Appears that none of out newer Toshiba laptops and neither of our brand new Asus laptops recognize the 5Ghz network sitgnal. Only PC in entire house that sees the 5Ghz signal is the old PC in the house running Win XP.
One of our locations recently upgraded their VPN router from a Netgear FVS318 to the Cisco Small Business Router RV042
My location uses the Linksys RV042v1.2. We can't get the VPN to connect. The VPN set up screens are similar, but there some parameters that we had to adjust. The SA Lifetime parameter for the Cisco Router defaulted to 86400 Secs (Phase 1 & 2) The SA Lifetime parameter for the Linksys only goes to 28800. So we adjusted the Cisco RV042 to match out Linksys RV042.
That's the only difference in the screens that I see. The Cisco has additional paramters under "Advanced", but they're all unchecked by default.
When they shipped the Netgear FVS318 over to us, we get the VPN to function, however, the Netgear has a max throughput of 10Mbps. (we get 4-5Mbps on Speedtest.net). The RV042 gives me over 40Mbps (Optimum Business w/Ultimate)
I tried both firmware updates on the RV042v1.2 RV042 v1.3.12.19 RV042 v1.3.13.02
Any compatibility issues between the different versions of the RV042?
I have a cisco wireless environment running NCS with a wism, two 4400's, and now two 5500's. The bulk of our AP's are 1131's, however we are now ordering and using 1142's and 3602's. We just added the 5500 controllers in preperation for a large deployment of 1142's. What I would like to do is have the system setup so that the the 1142's will default to the 5500 controllers. Since the wism and 4400 wont support the 3602's its not really an issue for them. I'm trying to find the best way to accomplish this. I've already heard one suggestion of manually going through and setting all the AP's to a primary and secondary controller but I was hoping to find a way to have the system do this for me.
Is there a newer tool for current versions of Checkpoint to ASA 8.4? I notice a lot of similarity between checkpoint and 8.4 now, but I still have to do it all line by line which has become a PITA.
A newer router that I got from a friend, a CISCO Linksys WRT310N, is not connecting to my XP computer via a CAT5e cable. It willconnect for about 5 to15 mins, then lose connectivity. Ihaven't tried with a faster CAT6, since my dog chewed through my other one,and I have yet to get a new one. I used an older NETGEAR B/G router and it worked fine.
We have a centralized Cisco 5508 WLC with 84 APs(1142N) in branches (slow WAN links), Current WLC IOS version is 7.0.220.0.Recently we bought new Aps Air CAP36021-N. These APs are not compatible with existing WLC IOS. If I upgrade WLC, then can I stop propagating newer firmware for old Aps? Because it kills all WAN.
I have an N300 (F9K1002v2) and I'd like to know if there are any firmware updates newer than 2.00.08, I've tried flashing firmwares 3, 4, and 5 but they all fail.
For many years we've had the following vlan and port security config on our 3560s: [code] This has worked great on 12.2(37)SE1, 12.2(40)SE and 12.2(46)SE. However since 12.2(50)SE, and I've tried all the versions since then, we have a problem with 7900 phones and ATA186s taking upwards of 20 minutes before they can get a valid IP number.The problem on the newer IOSes seems to be related to the inactivity aging.On the older IOS versions the mac address of the voice device appears on the voice vlan straight away.
On the newer IOS versions the mac address of the voice device appears on the DATA vlan and seems to be stuck there until the inactivity aging removes it. It then gets re-learned, sometimes on the voice vlan, and sometimes on the data vlan. If you're unlucky and it gets re-learned on the data vlan you've got to wait until the inactivity time ages the address out again. Repeat until the mac address eventually gets learned on the voice vlan. I don't want to be stuck on 12.2(46)SE forever.
From an older manual it describes how to configure this. I installed the oldest firmware available for download and this feature is there. Was this just simply moved somewhere else in the newer firmware?
Configuring Port VLANs You can associate VLANS on the Cisco RV220W to the LAN ports on the device. By default, all 4 ports belong to VLAN1. You can edit these ports to associate them
I'm looking at a dual-channel wireless-N router that transmitts at 2.4Ghz and 5Ghz, but none of our newer laptops even recognize the 5Ghz channel. Is there a configuration setting to change what frequency laptops can recognize? Looking to put 2 newer modle Toshiba loptops on the 5Ghz channel and leave two other...older systems on the 2.4Ghz channel.
We are looking to deploy ISE supporting 5000 devices and would like to use the Cisco UCS platform to host this. Looking at the spec required a C22 M3 would be sufficient; however we would also like to host some UC applications on the same server if resources allow.
Therefore we would like to deploy ISE on a C220 M3 server and connect the associated NIC to a DMZ. We would then like to deploy UC applications such as CUCM and CUPS on the same UCS server with a NIC attached to the internal network.
Also while the UC application would require a UC Foundation License (R-VMW-UC-FND5-K9) whould this also meet the requirements for ISE?
So I had an iphone 4 and switched my signal to B and G only to get better service since my iPhone 4 only had G so not worth having N.Speedtest.net is about 5.69mbps download.I got a new iphone 5 and switch to G and N mixed thinking I'd get better speeds.When I switched speeds stayed about the same.
I do want a mixed signal if possible for PS3, other iphone 4, and laptops that don't have N wireless.Is that to be expected? or is something else going on that I'm missing?I'm running Firmware Version: 1.35NA and Hardware Version: A4
I am doing a school research project in which I am setting up an OC-192 ring for a company (contract work through AT&T). I have chosen to use the Cisco ONS 15454 SONET MSPP as my platform. The company currently has locations in Chicago and Philadelphia and connects them through an OC-12C ATM connection and they are looking to add 2 gigabit ethernet connections.My question is what cards and parts will I need for the Cisco ONS 15454 SONET MSPP, and how much will everything cost? I have been searching the internet for components and prices and I have found it extremely difficult to find any information.
I currently have a 50Mbps Internet Connection provided by an ethernet handoff for hosting some webservers. We are looking at adding an additional 10Mbps Internetn connection and route BGP between the two. For the 50Mbps connection, i'm using a Cisco 2951 router. I also have another 2951 router to terminate the 10Mbps connection. Does these router have enough horsepower to fully route BGP?
I want to select catalyst 3560G for my network. But IOS SLB need to be implemented in my network. I only know catalyst 6500 series can support this feature and i am not sure whether 3560G can support this feature. what platform and IOS version i need to implement IOS SLB?
A make one BOM and i just ask my self can we order on the one platform ( for example 5510-SEC-BUN-K9 ) SSL Essentials license ( this license is on the platform by default we buy 250 users ) and i need 50 Users license from them to be Premium.
Can i buy those two license on the same platform and is this will work ?
During WAN troubleshooting, I did a "clear interface ser0/0/0" on a branch router. It has two WAN links. I lost ssh/telnet connectivity but both WAN links were still replying to pings. We did a manual power off of the router to regain connectivity.Is there a known issue with this command on this IOS version? We're using Cisco 2911 platform with IOS 15.1-1.T2 version.
If i go wired i get 100mbps on both my laptop and desktop unit if i switch to wireless they both go 135 to 150 mbps any ideas? both units have megabit cards. My laptop i use at work at 1.0gbps no problem. It doesnt change no mater where i plug into at home or with different cables same speeds
I have a Dell Latitude D530 - I am only able to,download at a speed of 2.95 while I can upload at nearly 7,My PC that is attached to the same provider will,download at 7.84 and upload at 7.96.
I live in an apartment complex with a few other roommates. We each have an ethernet cable jack in our rooms, and we also have a wireless router located in one of my roommates' rooms that we all use for WIFI. when connected to only WIFI, my interenet connection is faster than using an ethernet cable? Our WIFI network displays a speed of 65Mbps, while the ethernet network shows a 10Mbps.
