For a business that depends on technology, Cisco 1900 Series Integrated Services Routers (ISRs) deliver high-performance, highly secure connectivity with multiservice integration that can transform the workplace with a broad set of services, rich-media support, and operational excellence.

There are several Cisco 1900 popular stars including Cisco 1921/K9, Cisco 1921-SEC/K9, Cisco 1941/K9, Cisco 1941-SEC-SRE/K9, Cisco 1941-SEC/K9, CISCO1941W-A/K9, etc. Maybe it is hard for you to decide which one is the most suitable?

Cisco 1941 router or Cisco 1921 router? Not that complicated, look at some discussion from Cisco 1900 users or buyers, you will be clear about it:

The Cisco 1921 Integrated Services Router (ISR) brings you extremely protected data, portability, and application services as whatever you’re expecting. The primary features includes 2 integrated 10/100/1000 Ethernet ports, 2 enhanced High-Speed WAN Interface Card (EHWIC) slots, it has a ability to support 802.3af this power modules as well. if you concern the security it has a built in hardware encryption, together with this you can have extremely protected mutual communications.

Though you have mentioned two product with their series but let me tell you that there are multiple product with the same series, such as CISCO1941/K9 and C1941-SEC-SRE/K9 so still with the 1941 series you can have too many models, according to me you should first of make your own configuration and after that look for the model, after that you’ll be able to figure out which one would be better for yourself.

According to me you should prefer CISCO1941W-E/K9, it has a ability to support over 10 routing protocol such as OSPF, BGP, EIGRP, PIM-SM, IGMPv3, static IPv4 routing, static IPv6 routing and many more. The router is a evolutionary platform with multicore CPUs, if you have glance at the specification of this model, it will come to know that the hardware it has through which you can have very good performance, some of the features includes firewall protection, VPN support, Syslog support, IPv6 support, CBWFQ, WRED.

What Cisco Fans Talk About Cisco 1841

Cisco 1841 router is intended for use in small and medium branch offices.  This router is a low-end device making it one of the cheaper models produced by Cisco, and also Cisco 1841 is enterprise class and quite reliable.  As we expect, Cisco 1841 router uses the IOS software and uses Cisco standard cards to provide nearly any type of interface we want in it. 

Many people in IT are familiar with Cisco hardware and IOS so configuration and maintenance should be easier to attain than with another brand.  This is rack mountable making it fit much better into the wiring closet.  However it does only have a single power supply reflecting its intended place in the satellite offices rather than central routing for a large company. 

This particular model/CISCO 1841 series comes with the following features:

• 2 10/100  Ethernet ports  (copper - RJ45)
• 2 Wan Interface Card (WIC) slots for the ports of your choice
• 1 internal expansion slot
• standard pair of console/auxiliary console ports
• 1 USB port for console access (local device management)
• 128 Meg RAM; only expandable to 384 Meg. 
• 1U height

The Cisco 1841 routers come with three-speed fans which are controlled by a thermostat in the chassis.  The fan speed varies based on cooling demands which reduces noise and fan wear. Cisco 1841 comes with internal clocks, but is dependent on a non-replaceable battery.  Should the battery ever fail you will need to return the router to Cisco for battery replacement, although it should be covered by the warrantee.     

If you intend to use VoIP you will need a separate appliance as Cisco 1841 does not support either voice or VoIP despite having two WICs.  As with most low-end routers having only one power supply is a bane, although with most typical locations it would be installed in, it simply means not being allowed redundant power supplies, and breakers.  The Cisco 1841 router is a fine choice for a field office or a small office with less than 300 or so users depending on how they use it.  It is overkill for a job of less than 20 nodes where I’d recommend a smaller router or a PIX firewall.   It should be able to handle NAT, having more than one route to the internet or headquarters, as well as a reasonable amount of access control lists (ACLs).

Cisco Set to Acquire BNI Video

"Cisco believes, like many do, that the amount of video is only going to increase. It's already half of Internet traffic and I'm expecting it to be upward of 90 percent in the next five years," said Zeus Kerravala, principal analyst at ZK Research. "In order for ISPs to be able to control video quality and monetize it, these technologies are important."

Cisco's move to streamline its operations hasn't kept the company from making new acquisitions. Cisco plans to acquire BNI Video for $99 million.

A privately held company in Boxborough, Mass., BNI Video supplies service providers with two video products that offer video back-office and content delivery network or CDN, analytic capabilities.

Cisco is looking to BNI's technology to beef up its Videoscape TV platform. Videoscape lets service providers deliver video to any device over any Internet Protocol network. Cisco said BNI Video's technology would also help its service provider customers reduce operational costs and complexity and expand opportunities to monetize content.

"Cisco is committed to working with our service provider customers to deliver next-generation IP-based video experiences across devices," said Marthin De Beer, senior vice president and general manager of Cisco's Emerging Business Group. The BNI Video acquisition is part of that commitment by giving customers migration path to the Videoscape platform.

Cable Industry Encouraged

BNI Video has an industry background that may have attracted Cisco to become more than an investor. Along with Cisco, Comcast and Time Warner Cable were early investors in BNI Video.

Tony Werner, chief technology officer for Comcast, said BNI's technology has the potential to "play a critical role in advancing video experiences for Comcast's customers," and is encouraged by Cisco's acquisition of the company.

Likewise, Mike LaJoie, chief technology officer at Time Warner Cable, said the companies joining forces is an opportunity to "take video service providers to the next level with Internet video, helping to manage networks more efficiently to deliver advanced TV entertainment experiences to consumers."

Acquisition Trends

With the BNI Video acquisition that was announced Thursday, Cisco is putting its money where its mouth is. Cisco has stated that video is one of its five company priorities, the biggest growth driver for IP traffic and, as a result, the company's core networking business. The BNI Video acquisition follows the recent acquisitions of ExtendMedia and Inlet Technologies, which also strengthen Cisco's Videoscape portfolio.

"Cisco believes, like many do, that the amount of video is only going to increase. It's already half of Internet traffic and I'm expecting it to be upward of 90 percent in the next five years," said Zeus Kerravala, principal analyst at ZK Research. "In order for ISPs to be able to control video quality and monetize it, these technologies are important."

Kerravala also noted Cisco's recent acquisition trends. He expects the firm to return to doing smaller deals, below $150 million, until it gets the repatriation rates it needs.

"Most of Cisco's cash is tied up overseas, so people are trying to guess at what the next acquisition might be," Kerravala said. "It's going to continue to be companies like this that are very specialized, and do one thing well in one of Cisco's core areas. This is becoming the norm for Cisco acquisitions."
 

Common Questions & Guides for Cisco 1841 from Yahoo Answers

As we known, Cisco 1841 series is a super star among Cisco 1800 series,

Q: How to configure Cisco 1841 router to connect through satellite?

I am trying to configure my Cisco 1841 router to connect to the Internet through a satellite dish. I am stuck. All i need to know is what to do on my router. Sample config would be appreciated as well. I also want the outside world to access services such as web and ftp through the satellite connection
The connection is as follows
LAN----------|Cisco 1841 Router|-----------|Satellite modem|------Internet

A: Have you used another router in the past and you're just upgrading to the new Cisco one? If so, just copy the settings from the old router. If this is a new install, you're going to need the info from your satellite internet provider, like your login info. Your IP address if you have one (as opposed to DHCP), etc.

Q: Can I display a Cisco 1841 system info on my PC?

I am new to cisco equipments, I have a Cisco 1841. First is it possible to display a the router info on my PC. If so how do i connect the 1841 to my PC. And also can configure the router from my PC like the Linksys routers.

A: The Cisco routers are a professional grade router and way outperform the low end home grade routers like Linksys.
The Cisco 1841 can be configured using CLI (command line interface) with a serial connection and Hyperterminal on a Windows computer. It can also be configured using CLI using the LAN port of your pc connected to its LAN port.
Later models of 1841 also permit configuration via a Web GUI interface. (You are familiar with Web GUI as it is the only promulgated mode for configurations on low end routers.)
We do not know which version of firmware you have on your 1841 so we cannot tell you whether it supports the Web GUI mode or not. You indicate you are new to Cisco equipment but you did not indicate this was a new Cisco 1841.
The best way to determine this is to try to log onto it. You will need the user name and password. If these are lost, you can do a factory reset and use factory defaults.

Q: How can we use 3 ADSL line in Cisco Router 1841?

I have Cisco 1841 router. I already installed 2 ADSL WIC in both slot available on it. I want install one more ADSL WIC too in this router (3rd one)
Please let me know any way to adopt 3 rd WIC card on it ?. If not, please let me know , Is it available 2port ADSL WIC ?

A: Cisco doesn't make a 2 line ADSL WIC. You have 2 options:
1. Pull at least one of the WIC-1ADSL cards and install a WIC-4ESW 4-port switch and use external DSL modems.
2. Upgrade to a Cisco 28xx series router that supports more expansion cards.

Q: I would like to add more ether net ports to cisco 1841, which card i must use?

A: If you want to use these Ethernet ports as routed ports like build-in Ethernet ports, You have two options listed below:
HWIC-1FE 1-port 10/100 Routed Port HWIC
HWIC-2FE HWIC two routed port
If you are going to connect some PC or other devices, you can use switch ports like below:
HWIC-4ESW Four port 10/100 Ethernet switch interface card
You have only two slot in this router so choose carefully.

Q: How to enable bgp in cisco 1841 router?

A: You need advanced IP Services software image for this. See sources link [1] for further details, on how to upgrade.
See link [2] for configuration guide on BGP.
the quick answer is :
1.router bgp autonomous-system
2. network network-number [mask network-mask] [route-map route-map-name].
Configuring a good BGP router is not an easy task. You should read more about this, if you want to use it in a real-life network implementation.

Q: Cisco 1841 - how to NOT route between subnets?

I have an 1841 router connected to the Internet connection via one ethernet interface and half a dozen subnets via a trunk on the other interface. I want each of those subnets to be able to access the internet, but for security reasons I want to prohibit any routing between the subnets so they remain isolated from each other. How would I go about arranging this?

A: Have you made an ACL? Create one to block the subnet you do not want accessed and apply it inbound on the virtual interface.
If I remember right, something like this (i'll use 192.168.1.0/24 as the destination vlan).
access-list 101 deny ip any 192.168.1.0 255.255.255.0
Apply this inbound on the virtual int for this vlan,
virtual int 0/1
access-group 101 in

Q: Example config cisco 1841 with 2 hwic 4esw card using no vlans?

I have a cisco 1841 with 2 hwic 4esw cards and I want to setup the cards to work as L2 switches attached to the FE0/1 interface with the FE0/0 interface used as the connection out. All traffic thru the 2 switches would be NATed through FE0/0 also. Any ideas how I can do this without VLANs

A: How exactly are those two cards connecting to the Fa0/1 interface? You only mention the one router.
To NAT directly on that 1841 for switch ports on those cards, best way is to create an SVI and configure it as nat inside. That would technically require a vlan, but if it's dot1q tags you're trying to avoid you could always make it the native vlan or just the vlan 1 default. Those ports on the two hwics should be access ports anyway so it shouldn't be sending any tagged frames anyway unless you're trunking to something else that you haven't mentioned.
To give you a config I'd need to know what you mean by "I want to setup the cards to work as L2 switches attached to the FE0/1 interface". How are these cards attaching to the Fe (Fa?) interface of the router? You mean "attached" as in they're both part of the same physical router?

Q: How to configure ACL 115 on Cisco 1841?

Host 10.1.10.5 is not allowed to access host 10.1.50.7. All other hosts are allowed to access 10.1.50.7. Configure the ACL on B1 using ACL number 115. Please help!
A: Since I don't know which router is B1 incoming or outgoing traffic the ACL could be written for outgoing.
access-list 115 deny ip host 10.1.10.5 host 10.1.50.7
access-list 115 permit ip host 10.1.10.5 any
for outgoing traffic... would still need ip access-group 115 out on the interface.
alternately it could be written:
ip access-list extended 115
10 deny ip host 10.1.10.5 host 10.1.50.7
20 permit ip host 10.1.10.5 any

Source(s):

This one is a bit easier since your able to place the ACL nearest the point of origin on B1 and you can use an extended.
So the ACL is extended.
Applied to interface FA0/0 on the B1 router.
ACL should be applied to out.
access-list 115 deny ip host 10.1.10.5 host 10.1.50.7
access-list 115 permit ip any any
ip access-group 115 out
