Cisco Layer 3 Switches Review: Cisco 3750-X



The Cisco 3750 range has been around for many years now, and has a vast following. The Cisco 3750-X is the new kid on the Cisco block, and it combines plenty of stuff that will be familiar to users of its predecessors with some funky new features that are clearly a step forward.

Cisco 3750 switch comes in a number of flavors – between 24 and 48 ports, with or without Power over Ethernet. Cisco 3750 with 48Pis the PoE variant of the 48-port device. Now, the traditional Cisco 3750 had four 1Gbit/s SFP ports in addition to the 48 10/100/1000 copper ports; the Cisco 3750-X instead has a slot into which you can slot either a four-port 1Gbit/s SFP daughter-board or a two-port 10Gbit/s alternative.

Alongside the port combinations, there are three software installs. The LAN Base software is a layer-2 only software image, and quite frankly I wouldn't ever expect to buy one of these if I only wanted layer-2 functionality. More sensible is the IP Base image which makes the device a proper Layer-3 routing switch, albeit with a limited selection of routing protocols. At the top is the IP Services image, which makes the unit a full-blown router (just like its ancestors – two of my BGP-shouting WAN routers are actually 3750Gs, in fact). The main market will of course be for the IP Base version.

The rear panel is interesting too, of course. As with the older 3750s the rear panel has a pair of “stack” ports. Each stack port provides a 16Gbit/s backplane connection, and by stacking your devices in a loop you end up with a resilient 32Gbit/s backplane. From a management and configuration point of view a stack is a single virtual switch – you manage it rather like a chassis product with a number of blades. So port 1 of switch 1 is Gi1/0/1, port 3 of switch 2 is Gi2/0/3, and so on.

The important rear-panel innovation with the new CISCO 3750-X model is the provision for redundant power supplies. In the old model you had a single, non-removable power supply along with an RPS (Redundant Power Supply) connection; to use the latter and give yourself some resilience you had to buy something like an RPS2300 – an external device that was a stupid shape that didn't fit into a rack very well, had buttons on the front whose only purpose seemed to be to make things break, and on a brighter note provided up to six switches with resilient power. The new model has dual slots for removable PSUs, of which one is populated by default; it's a ten-second job to slip a second one in beside it. One of the downsides of the old 3750 was the bloody awful reliability of the internal (fixed) PSU, and I've spent rather too many hours swapping out units with duff power units, so the removable units in the -X are most welcome.

Along with the redundant PSU facility is the power stacking capability. Just as you have your data stack cables, you also now have a pair of power-stack cables on each unit, so that the total power available via all the PSUs in the stack is available for negotiated use across the whole stack, for switch power and PoE.

As with the older devices, you can add and remove stack devices on the fly. Adding a switch to a stack is a simple case of settings its ID, telling the stack to expect a new member, and plumbing it in (although in theory the stack will deal with firmware mismatches in the new member, I prefer not to tempt fate so I always pre-install the right version). If a unit fails the stack will keep on humming while you pull out the duff one and stick in the replacement, and the config will be automatically migrated to the new unit.

The only downside I've found so far, in fact, is with trying to get the new -X model to co-exist in a stack with the old 3750-G (in short, I've not persuaded it to actually work yet) but I've no doubt I'll persuade it to play before long.

The Cisco 3750-X is a really sensible evolution in an already popular family of switches in the Cisco family. Being an IOS device there's really not a great deal of difference management-wise between the old and the new, so you get new functionality with almost zero additional training requirements. I've recently added seven 48-port non-PoE versions in three of my server installations, and have just received two new pairs of the PoE variant in a couple of offices, and I'm pretty happy thus far.

Pro
New power stacking capability is an excellent evolution.
32Gbit/s backplane should be sufficient for most modest installations.
10Gbit/s Ethernet support for uplinking or connecting to blade servers.

How to Verify and Troubleshoot NAT Configurations?


The most common mistake in troubleshooting is not the inability to use commands but the laxity in the examination of entries and configuration. Solving network problems requires careful and proper examination of routing entries and configuration.

There are several useful router commands to verify NAT translations. Cisco routers are equipped with NAT verifying tools.
1. The command: show ipnat translations display the details of NAT assignments; it will enable you to verify that correct translations exist in the translation table.  It’s recommended that you clear any dynamic NAT translation entries that might still be on the router.

2. To view additional details about each translation us the following command;
              R1#show ipnat translation sverbose

This command will display additions information, which includes creation dates and usage of each translation.

To clear NAT translations use the command:  clear ipnat translation
e.g.

R1#clear ipnat translation

3.Verify the operations of NAT by checking details about every packet that is translated by the router. To view this information use the:
                R1#debug ipnat  or
               R1#debug ipnat detailed

The later command debug ipnat detailed Provide a description of each packet that had been considered for translation. It also displays information on some errors such as failure to assign a global IP address.cisco product

4.The show ipnat statistics command display:
Details of all the active translation entries
NAT configuration parameters
Number of IP addresses in the pool
Total number of assigned IP addresses.

Another useful command for NAT verification is the show run command. With this command, you can view the;
Access command lists
Interfaces and other configurations

The most common mistake in troubleshooting is not the inability to use commands but the laxity in the examination of entries and configuration.

How to Create a LAN Connection Using an Ethernet Cable?

Having multiple computers at home doesn't mean you need to have multiple Internet connections. If you have a router and a few Ethernet Cisco cable, you can share an Internet connection among all your computers and even transfer files between them without having to use a CD, floppy disk or jump drive.

What you need to create a LAN connection using an Ethernet cable is Router Ethernet cables

How to Create a LAN Connection Using an Ethernet Cable? Follow these steps:
1. Insert the software disc that came with your router into your computer's CD or DVD drive. Follow the on-screen instructions to install the software.

2. Plug the AC power cable from the router to an electrical wall outlet. Connect an Ethernet cable from the port on the router that says either "WAN" or "Internet" to the outgoing port on your broadband modem.

3. Connect an Ethernet cable from the Ethernet port on the back of your computer to one of the open ports on the router.

4. Run Ethernet cables from any other open port on the router to any other computers you want to be added to the network.

5. Click on the "Start" bar at the bottom of your desktop and then choose the "Control Panel" button. Click on the link that says "Network Sharing Center" and then click on the button that says "Set up A Network Connection."

6. Check the radio box that is marked "Connect to the Internet through a gateway" and then click "Next." Type in a name for your network and then hit "Next" again. Press "Finish" to set up the network.

7. Go to the other computers on the network and navigate to the Control Panel again and then choose the Network Sharing Center. Click on "Connect to a Network" and then choose the network you set up on the first computer.

Tips & Warnings
It doesn't matter which open port you use on the router to connect an Ethernet cisco cable price to your computer, as long as you don't connect it to the "WAN" port reserved for the modem.

Keep the Ethernet cable in an area where it can't be tripped over or accidentally pulled out. Running it across the ceiling or on top of a wall using tape or a cable runner will keep the cords out of the way.

How to Use Cisco Static Routes?

Static cisco routes while manually intensive to keep up, are a very quick and effective way to route data from one subnet to different subnet. Let’s start with the basics.

What is a static router?
- a static route is a hard coded path in the router that specifies how the router will get to a certain subnet by using a certain path.

What do you mean by "hard coded"?
- you or someone has typed in the network ID and the next hop to get to the network specified

How do I add a static route into my Cisco router?
- Pretty simple
router# config t ; get into the configuration mode
router(config)# ip route A.B.C.D (destination network/host) A.B.C.D (mask) A.B.C.D (next hop); this is a simple static route

Are there any other ways to name the next hop except by using an IP address?
- Yes, you can use the port name i.e. ethernet0, E0, S0 and so on

What is "distance metric" that I can add at the end of the command?
- All routes have a value that allows the router to give a priority to which type of routing is used first. In static routes, the value is 1 which means no matter what other protocol you may have running like OSPF or RIP, the static route will always be used first. This can be changed to special needs. for example, if you have a frame link with ISDN back up, you can static routes for the frame and a second set of the same static router but with a distance matric of 255. This means while the frame is up, it goes first but when the frame goes down, the router will try to use the 2nd static which is normally ignored due to the 255 value.

Why do I want to use static routes when there are neat routing protocols like OSPF?
- static routes are easy, no overhead either on the link or the the CPU of the router. They also offer good security when coupled with a tight IP mask like 252 which gives only 2 hosts on a given link

If static routes are so easy, why not use them all the time?
- Static routes while easy can be overwhelming in a large or complicated network. Each time there is a change, someone must manually make changes to reflect the change. If a link goes down, even if there is a second path, the router would ignore it and consider the link down.

One of the most common uses of a static map is the default classless route
- ip classless
- ip route 0.0.0.0 0.0.0.0 [next hop]

This static map says that everything is remote and should be forwarded to the next hop( or supernet) which will take care fo the routing.

Dial on demand is also a big user of static routes. Many times with dial up or ISDN, you do not have the bandwidth or you do not want to pay the connection fees for routing updates so you use static routes.

Static routes allow you to set up load balancing after a fashion. Keep in mind that the IOS load balances across routes first and not interfaces. The easiest way to configure multiple routes on the same interface is to use the secondary IP command

Router 1
!
interface serial 0
 ip address 192.0.0.1 255.255.255.0
 ip address 192.0.0.2 255.255.255.0 secondary ! second route on same interface

interface serial 1
 ip address 192.1.0.1 255.255.255.0
 ip address 192.1.0.2 255.255.255.0 secondary

ip route 200.2.0.0 255.255.255.0 196.0.0.4; goes to serial 0
ip route 200.2.0.0 255.255.255.0 196.0.0.5; goes to serial 0
ip route 200.2.0.0 255.255.255.0 196.1.0.4; goes to serial 1

Router 2
!
interfaceethernet 0
 ip address 200.2.0.1 255.255.255.0
!
interface serial 0
 ip address 196.0.0.4 255.255.255.0
 ip address 196.0.0.5 255.255.255.0 secondary
!
interface serial 1
 ip address 196.1.0.4 255.255.255.0
 ip address 196.1.0.5 255.255.255.0 secondary

The traffic would go out router 1 across the two IPs on serial 0 first then across 1 IP on serial 1
This gives you unequal load balancing.

Notes: This is just the basics of static routing. You can get very creative if you want and take things further then described here. I would suggest "Routing TCP/IP Vol 1" from Cisco Press for more information.

Routers, Different Types to Serve Your Network


There are several types of routers you may hear of:wired router, wireless router.
More detailed classification: Internal cisco router sale (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; Backbone router (BR): Interfaces to backbone; Autonomous system boundary router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails.
If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of router.Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go.Generally, Routers that we used can either be wired or wireless. 
A wired router will generally connect to your computer and computers or hardware through an Ethernet cable.  This happens with the use of output ports.And the only input port provided on a router will be used for the Internet. 
A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections. You will know the router you are using is wireless if it comes with an antenna.  The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the cheapest cisco adsl router, provided they have password access.
Two Typical Routers We Usually Used
Commercial Router
If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router.  These routers are much more powerful than what you would purchase at your local electronics or computer store.  The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem.  Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN.(Cisco is a leading router manufacturer to aim to provide router and networking solution to small, medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town.  The commercial-grade will be used reset cisco router to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other.The local area network may consist of one large office within a building.In that case, you could have multiple LANs connecting to the WAN through one or multiple routers.
Consumer Routers
If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store.Generally you will want a router that serves as a wireless access point (WAP).It should also be a network switch.The wireless access point (WAP) basically provides the wireless access that everyone wants. That wireless access can be both to the Internet and to other computers in the home or office.Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths.Some of the lower priced consumer routers will not have a very strong firewall.
