LAN design

Hi all,
My company has 4 departments spreading among 4 buildings. Each buiding is about 300 users. Should I use 1 subnet for each deparment and do a trunking between building or should I 4 subnets for each deparment and do routing between building?
thanks

It depends on the technology you use to connect the buildings. If you have a fast technology, e.g. dark-fiber Ethernet, then I would go for one VLAN per department, trunks between the buildings, and route then at the core/distribution layer.
There seems to be a trend towards geographically-based VLANs, e.g. one VLAN per closet, but I do not like that architecture so much, especially if the departments have their own servers. I much prefer one VLAN per logical grouping.

LAN Design Question

Hi Team, i need some information regarding LAN Design, Please see Diagram 1 Current Setup. in which when our Core switch trunk ports are full we install 2 aggregate switches and connect both aggregate switches with core switches.
but mostly in documentation i see connectivity as mentioned in 2nd diagram with name "setup online" , where RED lines are added, i mostly see such full mesh physical connectivity.
May i know if there is any real problem in first design? where we only connect Core1 with Aggregate 1 and Core 2 with aggregate 2?
thank you in advance.
Just to add HSRP is running on LAN side between both Core and all LAN gateway are on Core switches. and EIGRP is running between 2 routers and 2 Core switch.

Wow ... 3560G core and you want to do multiple redundant links. One word will sum this all up: NIGHTMARE.
On paper, you'll be able to get this right by fine-tuning STP, PVSTP, MSTP, etc. In the real world, I wouldn't touch this scenario. Not with a switch that does NOT support stacking.
Let's say your core is a stack of 3750G/E/X or 3650 or 3850 and your access switch are 2960S/X/XR. If this is the case, then you'll have a pair of routers with their links going down to a stack of 3750 and from the stack of 3750 you have links going down to the access switch.
NOTE: I'm holding back the "method" because I'm waiting for more information from you.

LAN design - how to implement a core switch?

Hi all,
First post here so please be gentle :-)
I'm looking for a bit of advice with a LAN setup I've been tasked with.
The basic requirements are to have a demonstration suite of servers/storage devices networked with internet access with certain devices segmented in different VLANs. Also, a separate VLAN is required for training and meeting rooms which will receive DHCP addresses from a WIN2K3 server.
The kit I've inherited consists of:
1 ADSL Modem/Router
1 2611XM router
2 Catalyst 4006 switches with Supervisor II engines (CatOS :-( ), one with a layer 3 routing module
Several Catalyst 2950/3500xl switches
Netscreen 100 Firewall
F5 Firepass for VPN
After a lot of fun resetting devices I've currently setup the LAN with a router on a stick configuration which routes between different VLANs (on the 3500/2950s) and which has internet access via the 2611 and ADSL modem router in turn. That's about as far as my current knowledge goes I'm afraid!
What I have to do is incorporate the 4006s but I don't really know how to go about it or what's the best way to use them. How would I use them as core switches?
I was hoping someone could point me in the right direction on the best way to connect the switches up, i.e. network design, cabling (fibre uplinks between switches) and some basic configuration advice with the layer 3 routing module.
Any advice will be most appreciated!! It's my first networking job and I'm a bit lost.
Thanks.

Peter,
I would do the same - with a twist...
Have 1 4006 as a VTP server, also the spanningtree root for all vlans.
Have a trunk between the two 4006's - and make it an etherchannel 2 or 3 ethernet links (redundancy).
Make the second 4006 also a vtp server (redundancy) and have that 4006 the secondary 4006 for spanningtree (more redundancy!)
That way if you decide to have a distribution layer - you have 2 uplinks into the core 1 into 4006-1 as the primary, and the second 4006-2 as the secondary.
You could then have a trunk (etherchannel) between the distribution switches, then have a access layer into the distribution layer with duel links. This way you could have multiple switch and or link failures and still work!!!
You use the layer 3 module to do the inter-vlan routing - correct. Then have your adsl modem/router as the gateway to the internet - you put a default route in the layer 3 module point to the adsl modem! then you have the routes for the various vlan subnets pointing from the modem back to the layer 3 module......done!
HTH.

LAN Design Recommendations?

Hello,
We have a 48 port 2960G switch distributing our LAN to numerous 24 port 2960G switches.
We have been talking about bringing in another 48 port 2960G switch for redundancy.
Can someone please let me know what the best design options are for this setup, in terms of redundancy and possibly even load balancing? I am interested to find out what Cisco technologies/features are recommended in this situation.
I created a quick drawing of what we currently have and what we are thinking about. None of these devices have been put into production yet. Let me know if you have any questions, thanks.

Ok, scratch all that. My project has been updated, to the point where my design needs to go back to the drawing board. I was told to implement 100% end-to-end redundancy (from the distribution switches to the servers).
We have nine racks of servers for this project. Each rack will get a primary access switch, and a secondary access switch. That is a total of 18 access switches. These switches will all have uplinks to two distribution switches. For the servers themselves, we will utilize NIC adapter teaming. The server network adapters will be configured in a primary/secondary relationship. I have an example drawing of how I think one rack would be laid out.
- The two distribution switches are 2960G, 48 ports (already purchased).
- The access switches are 2960G, 24 ports (already purchased).
- There will be a total of five vlans, but only two of them will carry around 90% of the traffic.
- The network will be strictly data. There is no voice traffic.
- There will be a ballpark of around 60 servers (no more than 10 servers on a rack). Almost half of these servers are only there as backups.
- There will be no end-user workstations off any of these switches. This is strictly a server farm.
- I do not have a strong feel of the overall traffic on this network, but I was told that it could pass a few terabytes per day (moderate-low load I suppose?).
I have a number of questions....
1. Can two 2960G switches effeciently handle the stress of connecting to 18 access switches each? There will also be other links on these distribution switches, such as connections to the internet and end-user access from our corporate network.
2. All five vlans will be propagated to all of our racks. I was hoping to balance the traffic by vlan. Make one distribution/access switch the primary link for one vlan - while making the other distribution/access switch the primary link for a different vlan. Is that feasible under my circumstances?
3. Etherchanneling the trunks (that is, having two or more links from a distribution switch to an access switch) would not be possible, because you can only configure six etherchannels per switch total. My distribution switches would have 18 different etherchannels (one channel for each access switch). Am I right in thinking this?
4. Will NIC adaptor teaming on each server effectively work in this scenario, or is there a better solution for redundancy? I read this can be done with Cisco's Link-State Tracking feature.
5. Are there any modification suggestions to my drawing, or is that the best end-to-end redundant method for my situation?
Feel free to ask questions. I look forward to some feedback, and appreciate the help.

Simple LAN Design Question

Hi All,
I am trying to design a small LAN using 3 Extreme Summit switches as access switches, all L2 only, 1 Cisco 6509 as core/distribution, and 1 Cisco 3825 router for WAN access. There are 3 VLANs required, 1 on each Extreme switch. What is the best way to connect everything?
I have been considering creating trunk ports on the 6509 to each Extreme switch. Then enabling routing on the 6509. Does it make sense to trunk even though I only have 1 VLAN going across the trunk? Is there an alternative?

... if asked 'should I trunk between switches' I'll never understand why people refrain from trunking just because the dont need it at the moment. One aspect often overlooked is the ability to transport Layer2 QoS designation inside the .1q tags. Another alternative is the enabling of DTP (dont know if Extreme has this feature). If used wisely - considering the LAN-security implications - its a great feature.
We buy and sell Cisco equipment with a bunch of world class features - and dont use much of 'em. Most of these features are even tought at the CCNA level.

New LAN Design Help

I'm new to Cisco and hoping to implement a large Cisco solution. Unfortunately we're not in the position to hire an expert so I'm seeking some much needed advice!
The general plan for phase 1 would be:
A router with 9 interface cards, that will have a 4Gbps trunk to an Internal Network Switch, 1gbps to DMZ switch, 1gbps to WLAN router, 1gbps to identical router for HSRP, 1gbps to WAN switch, and 100mbps to Internet router
The router will need to participate in OSPF, HSRP and do trunking. It needs to do IPSEC vpn tunnels
The Internal Network Switch would have about 40 Vlans to individual departments. Each department uplink to the Internal Network Switch would be 100mbps. Eventually this switch will be doubled up for redundancy.
There would be about 1000 clients going through it via the Internal Network Switch, and through the Router, using the DMZ servers as well as the Internet.
So I have a few questions regarding this setup:
1/ Which type of router should I use?
2/ Which type of switch should I use?
3/ Is the network schema at all correct or would there be a better way of doing it?
Hoping for some help!

1) I recommend going with Cisco 2800 ISR for the IPSec VPN http://www.cisco.com/en/US/products/ps5854/index.html
2) I recommend going with Cisco 3750G for the DMZ, WLAN, WAN switch connections. This switch provides (with the right image) HSRP, OSPF, EIGRP services.
http://www.cisco.com/en/US/products/hw/switches/ps5023/index.html
3) Drop all connections down to the 3750G (all ports support up to 1Gb speed) and perform all the routing there as well as layer2 VLANs.
Nice, clean and inexpensive solution.
In addition, 3750s support stackwise cabling so if you purchase more than one switch for port density, in the config it looks like a single switch.

EtherChannel and LAN Design for new buildiing(s)

What is the recommended best practice for EtherChannel size for a 3750G-12S stack? Will I benefit from stacking these with the StackWise cable on the backplane, or would it be better to run these independently back to the 4006 with individual EtheChannels?
The 3750G-12S stack will likely be 1 or 2 devices at distribution layer for upwards of 18 - 20 2960G-48 access layer switches and approximately 20 1242LAP AP's in addition to max capacity of end users attached to the switches.
I am considering implementing a 4 gig EtherChannel between the 3750's to the 4006 for this load. My limit is the number of available ports on the 4006 and obviously the max load of links on the EtherChannel.

Unsure there's a single "best practice" for stacking or not. Some advantages/disadvantages to both. Part of the decision might rest on whether the 3750s will be L2 or L3.
Stackwise could be a performance bottleneck if you believe there would be much traffic between switch ports, but if most will transit your 4006, your links to it would be the bottleneck.
What you might consider, a single 3750G-12S (four?) that can handle 2 links from each access switch, that are Etherchanneled and not connected to the same 3750 stack member. This with the 4 gig Etherchannel to the 4006, which again should be spread across stack members.

High Availability LAN Design

Hi,
Consider the following:
H1------S1----R1----ISP1
H2----- S2----R2----ISP1
H1/2 are dual-homed hosts.
S1/2 are WS-2970G-24's.
R1/2 are 7204VXR's with NPE-G1's connecting to redundant links in providers PoP.
Was hoping to implement HSRP but can this be implemented? The 2970's ( running Enterprise IOS) can't do layer 3 routing, right?
How would you connect redundant links to NPE-G1 gig ports and make them act like two switch ports?
Any advice appreciated.

Apologies. I'll try again.

Wireless AP design for Wireless IPPhone 7921

FOr a client they are asking 40 Wireless IP Phone, with 3 floors, IPT side I am clear in design, but for access point design I am bit confused with standalone and WLC design.
Could please light me on Wireless design for standalone AP and WLC controller with AP , in the design plan to give both as options.
And also how to confirm a AP is a standalone or it wil work only with WLC.
Please light me with wireless design for IPT.

I would suggest you subcontract this to a partner who is familiar with wireless voice designs. There are a lot of details and caveats to make sure it works.
For example: autonomous APs are not viable for voice installations. You need a controller to prevent the roam times from interrupting the call.
At a minimum, you should read the Voice over Wireless LAN Design Guide:

Wireless Network Design

What are best practices in consideration to wireless network design? I have a WLC 4400 and 1200 AP's that I want to deploy to replace my existing wireless network. I am researching the best network design for implementing a secured wireless infrastructure and also having a quest account for non employee's to logon to and surf the Internet. We also have WAN sites that need to be included in this design.
Any help would be appreciated.

Hi Uzma,
It is likely in this day and age that when creating a Large WLAN that you will be using a "Lightweight" architecture. Here are some good "getting started" Cisco docs (and link to a video) which might help with your initial steps.

Design and configuration tips & suggestions

This is the current configuration of switches I have setup on our network. Its about 150 miles long(east-west) and about 20 miles wide(north-south). All of the locations are connected via a wireless bridges(trango, tranzeo, smartbridges) or via an ISP private vlan. Currently I have the 3550's connecting to each other via ospf and they are all doing inter vlan routing. The 3550 at location 20(3550-20) is I guess one of the main switches. Its located at the data center and it has the most connections to other wirelessly connected buildings. I have it configured to do pbr to 4 different DSL connections and it also has the switches from the data center connected to it. The small to medium sized locations have 2950's or 2960's.
To give you an idea of what is all going on now:
18 Wireless Bridges
1200 Workstations
30 Servers
3000 Users
21 Mbit of internet access
200 Gig's of Data being Backed up over night
1 Local server at each location
We are planning on implementing a video conferencing system soon as well as voice services in the future.
What I would like to know is what is the best configuration for these switches to prepare them for video conferencing, data connections and maybe voice?
Vlan Configurations?
Trunking?
Routing?
QOS?
Any ideas or suggestions on configurations would be great. I want to make sure I go about this the right way the first time so I'm not reconfiguring when we want to setup the video or voice services.
Thanks,
Dan.

Hi,
when designing and implementing a video and voip network there are many things to consider. So I will not try to list some of them but would recommend you to read through
1) "IP Videoconferencing Solution Reference Network Design (SRND)"
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns280/c649/ccmigration_09186a00800d67f6.pdf
2) "Enterprise QoS Solution Reference Network Design Guide Version 3.3"
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns432/c649/ccmigration_09186a008049b062.pdf
3) "Campus Network Multilayer Architecture and Design Guidelines"
http://www.cisco.com/application/pdf/en/us/guest/netsol/ns656/c649/cdccont_0900aecd804ab67d.pdf
QoS will be needed in any case and there are separate chapters regarding your different Catalyst switches.
Generally VoIP will be transported in separate Voice VLANs interconnected through IP routing. So you should also have a look into your overall LAN design. 3) gives you a guidance to a robust modern switching design.
Hope this helps!

an electron spectrometer system in the WMU accelerator
laboratory. The program was written in LABVIEW.
The project involved controlling and retrieving
data from devices on a CAMAC crate as well as
GPIB (IEEE-488) instruments connected to the system
via a GPIB to CAMAC interface. A computer communicated
with the system via a serial (RS-232) port on the
crate controller.

NAT Configuration

During the Christmas holidays I'm going to be fine tuning our server and was thinking that the NAT service may benefit our network. We have approx. 35 windows machine accessing the Internet and normally all at once with one public IP address. So I think NAT may help resolve some issues but I have a few questions.
Currently the server is using eth0 directly into the switch and the VPN appliance is also connected to the switch. The server dishes out IP addresses to the LAN while the VPN appliance is manually set with it's IP address. According to how NAT configs, eth0 will connect directly to the WAN port on the VPN unit and eth1 will be connected to the switch. When your setting up eth0 how is this configured? Do I manually set an IP to reflect my private LAN designation and does this now become my 'Gateway' when I'm setting up server eth1 settings.
I'm a bit confused. Any help would be appreciated or comments on my setting up the NAT service.

No offense, but I think it's clear you're a bit confused.
We have approx. 35 windows machine accessing the Internet and normally all at once with one public IP address. So I think NAT may help resolve some issues
If you have 35 machines sharing a single public address you're already using NAT. Therefore either the issues you're having aren't related to NAT at all, or they are NAT-related but having your server run NAT isn't going to resolve them.
It isn't yet clear to me what the issues are that you're trying to resolve. Can you elaborate?
Given what you've said so far:
Currently the server is using eth0 directly into the switch and the VPN appliance is also connected to the switch.
OK, makes sense so far...
The server dishes out IP addresses to the LAN while the VPN appliance is manually set with it's IP address.
OK, this makes sense, too - pretty standard so far.
According to how NAT configs, eth0 will connect directly to the WAN port on the VPN unit and eth1 will be connected to the switch
OK, this is where it breaks down. Why do you plan to connect eth0 to the WAN port of the VPN? Typically the VPN server will have one WAN port and one LAN port, but it may be able to run on a single link
When your setting up eth0 how is this configured?
How is what configured?
Do I manually set an IP to reflect my private LAN designation and does this now become my 'Gateway' when I'm setting up server eth1 settings.
You've lost me completely here. What device are you configuring here?
Do you already have the VPN in place? Is that already operating?
If so, why do you see the need to change this?
