Cisco Switches
Jun 19, 2007Is there such a switch?
Do cisco do a 24 port 1000Mbs switch that you can control each port speed through a web based software?

L2 Switches......Cisco, Dell And HP
Aug 9, 2009we are a small shop...
Not looking to buy another switch but we have a crapshoot of switches around. Dell 5448,
HP 2910 and a Cisco 3560.
I'd like to keep the the Cisco back in HQ stock since it's a POE switch.
We are colocating just 1 SAN intially. Max of maybe 7-8 Servers total in the future. Not alot of bandwidth and doing L2 traffic only. Any issues with either the Dell or HP in the colo environment from a production standpoint. We have used a couple of Procurves in our environment, and the dell switches were freebies that were part of our last order.
Basically, it would look like this
ASA5510 serving as main headed VPN
2 Branch Offices connecting to it
One L2 Switch. 2 - 3 Seperate Vlans with a trunk port back out to the ASA5510
Cisco Switches - Traffic Shaping Required
Jun 9, 2008I was checking out the switch products from Cisco and I noticed that there is quite a few products that been discounted, and I am trying to find correct switches that does traffic shaping on port for inbound and outbound.
I preferred they are 48 ports with 2 Gigabit uplinks, with Enterprise L3 image and it is little difficult to find the correct older models that is being sold on ebay to pick up the correct one.
I am also open to Extreme and Foundry switches as well, but I rather like to stick to one type for deployment, since I am working on the plan to deploy 2 core switches which all edge switches will hook into it.
Cisco 2950 - How To Enable "Cisco Network Assistant"
Dec 16, 2007My host has helped me to install a switch. However, I don't know how to configure using the command line. Could anyone help me?
I need to be able to connect to my Cisco switch using Cisco Network Assistant. If you know the command sequence,
Switches
Nov 23, 2007I am building an advanced network in a big building which will be used by desktop/printers and backend thin servers, which requires high-available network and consume high bandwidth all this thru categorie 6 cables (RJ-45).
The idea is to build different path with optical fibers and to connect each part of the building with it's own optical fiber to the server room (where we run Microsoft company network servers, SAN, backup, and external access) using a 10/100/1000 switch and optical fiber for long distance.
So I though about using switches which have at least :
48 ports 10/100/1000 (auto negociation)
4 ports 10 gE
for now I will not use many features but with time I could create some trunk, and use some advanced *routing* (switching) features.
As the budget is also not unlimited, I thought about buying :
Edge switch :
§ HP ProCurve 2900-48G J9050A [url]
with X2 extension HP ProCurve 10-GbE X2-SC SR Optic J8436A [url]
Core switch :
§ HP ProCurve 6400cl J8433A [url]
As I am studying any network vendor (but not such as 3com, netgear, dlink, linksys), but more such as HP, Extreme, Cisco, Foundry I am opended to your model ideas for me needs!
Switches
Apr 1, 2007I am in the market for some new switches and I was going to buy some HP stuff, but a friend of mine recommended 3com....their prices are dirt cheap....any experience with them?
Does anyone have any words to compare and contrast the two based on experience?
NIC Bonding And Switches
Jul 2, 2008I just stumbled across mention of bonding two NICs to serve as one. (E.g., 100Mbps NIC + 100Mbps NIC = 'virtual' 200 Mbps NIC, as far as everything on the network is concerned.)
I'd been familiar with the concept for quite some time, but I guess I never really thought it through until just now...
How does this work with switches? It seems to me that the answer should be a flat, "It doesn't." But it seems that it does work. How does the switch merrily map an IP to two different ports? Do the two NICs maintain their MACs? (Wouldn't two MACs to one IP cause even more problems?)
L3 Switches With Ipv6
Sep 12, 2007to buy some more Layer 3 switches but I'd like to get ipv6 support. I like the Cisco 3550 but it does not support ipv6.
Can someone recommend a switch in the same price range (less than $1400 for 48 ports) that supports ipv6? This will be used for connecting to customer servers.
Buying HP Switches
Dec 25, 2007where I can get the best price for HP switches? Looking for 1x2848 and 1x2650

Jun 28, 2008basic layer2 10G, most everything out there has more advanced L3 features which is fine but aren't nessecary, they maybe used at some point in the future.
Currently looking at the cisco 4900M as it appears to be very cost effective at ~$10k/ for the chassis w/8 port 10gb base, + xenpack cost and it isn't a very costly piece of gear.
Anyone Use Dell Powerconnect Switches
Apr 29, 2008Does anyone use Dell PowerConnect Switches?
If so please list what model number you use and your thoughts as compared to Cisco switches.
Once again I would like model numbers you are using.
Choosing Ethernet Switches
Feb 22, 2007We're ready to setup 3-4 42U racks for servers and are in need of choosing Ethernet switches. What do you guys use and why?
I'm looked at Cisco switches, but lost in their product forest. I'm looked at Express 500, 2960 and 3750-E models. Is there any more difference (in exception of stacking, cli and hot-swap fan/psu) that I need to consider? Prices differentiate too much.
I'm also looked at Linksys/D-Link business products and they seems to have the same features as Cisco Express series, but only 50% cheaper.
Opinions On Extreme Networks Switches
Mar 5, 2007I had the chance to work with the summit24 switches, and I personally liked them. It is straight-forward in my opinion for the Web Interface compared to others I have seen and the pricing seems to be reasonable.
I was wondering if anyone has had any experience with any of their switching devices.
Rsyn --backup --backup-dir Switches For Incremental Backs
Jan 26, 2007I current do some rsync backups with a command like so every day
rsync -az -e ssh --stats --delete --exclude "stuff" / user@server:/home/user/
What I want to do is have some incremental backups in there in subdirectories. So, for example, something like this on the remote server
/home/user/something.tuesday
/home/user/something.friday
I thought the --backup --backup-dir Switches were used to store just the files that had changed in seperate directories, am I wrong on that?
I've read everything I could find, including the big rsnapshot scripts, but I'm not able to do what I want, it seems so simple but something's not right, am I wrong that subdirs should have just files that are new or have changed. I tried various things like this, but had no luck
rsync -az -e ssh --stats --delete --backup --backup-dir=/home.Thursday --exclude "stuff" / user@server:/home/user/
Cisco Pix 501

Jan 13, 2008I just got a Cisco PIX 501 from my IT Guy for home use and he didn't reset the firewall to default settings so there are ton of old commands in here.
Is there a command I can use to reset the firewall back to the factory default settings?
Or is there anyway I can flash it back to factory default settings?
Cisco ASA
Apr 19, 2008I am interested to buy a Cisco ASA firewall. So far I have never played with this gears and I wonder if it is easy to setup.
Is there any software provided by Cisco to setup rules and ACL thru some graphic interface software ?
Which Cisco Firewall?
Aug 21, 2007We are looking to replace our existing WatchGuard Firebox's with a hopefully more reliable firewall from Cisco's range although I'm a bit lost when it comes to the different ranges.
Could somebody suggest a firewall that is capable of:
1: Both NAT & Drop-in (bridge) mode
2: Pretty low bandwidth requirements, no more than 10mbit/s traffic
3: SNMP Monitoring
4: High availability pairing
Cisco Routers
Mar 25, 2009I am on a tight budget for a Cisco firewall. I am browsing and seeing some affordable options in the x600 series.
Please tell me, which series is best?:
1600
2600
3600
The higher the better?..
Also what about submodels, like is 1650 better than 1600?
And how can I tell how much DRAM each one can take up to?
Cisco Guard
Apr 22, 2009I see a lot of DDos related articles here at WHT. We've got hit multiple times by DDos and had to handle those attacks everytime with a different approach.
The largest one and the most well know one (we were in Times Mag, AP news, CNN, slashdot, you name it - just do a search about us on WHT) was Russian botnet cyberattack - we had to anaylyze netflow and then block everything on our edge routers, then on the firewall and then locally on the servers.
Since then we had number of other attacks, some of them we were not able to defend on the server level, while, as you can understand we can't do netwflow and manual intervention evey time somebody gets an attach.
We have very good scripts which allow to mitigate huge number of DDos attack, whet our scripts are finding attacking IPs and blocking them automatically - still some attacks could be blocked only on the router level.
I've read that Cisco Guard (I am interesed in 65xx version of it) suppose to mitigate DDos attacks in automatic mode.
Cisco Redundancy
Sep 25, 2009after months of disruption moving servers into a new data centre, our once reliable colocation company has now had nearly 6 hours downtime in the last 16 hours. So much for network redundancy.

Also which firewall do you guys recommend for a rack of servers
Which Cisco Router To Use
Jul 11, 2007I am currently looking at these Cisco switches:
- Cisco 2924 WS-C2924-XL-EN Enterprise Switch
- Cisco 2950 WS-C2950-24 Catalyst Switch
- Cisco 3512 WS-C3512-XL-EN Enterprise Switch
- Cisco 3524 WS-C3524-XL-EN Enterprise Switch
- Cisco 3548 WS-C3548-XL-EN Enterprise Switch
1) I was recommended to chose the XL-EN model switches because it seems they have more Memory, but the second one in the list (Catalyst) is not a XL-EN, is that going to have any affect performance wise? or it doesn't really matter?
2) I was also recommended to choose managed switches because that way I can use the SNMP features to measure bandwidth, are any of the switches above unmanaged?
3) I also want to be able to manage the switch remotely, web managed, are any of the switches above web-manageable?
4) Most importantly, when my datacenter give me a 100mbit drop, I dont know which port to plug it in in the 29** series. In the 35** I see it clearly but I am not able to see it in the 29**, any ideas?
5) On some of these switches I see a special port called "Console", what is it? where does that connect to?
6) Do any of the switches above not have a console port?
Cisco ASA Security
Sep 28, 2007My network currently looks like this :
ISP ->> L3 Switch ->> Firewall (Transparent Mode) ->> Switch ->> Servers
I have a single /24 and my firewall is on x.2 and routes traffic for each of the servers.
Now i have a new Cisco ASA 5510 that i want to replace the aging firewall currently in place, however i dont want to put the firewall into transparent mode because i dont want to lose all the functionality.
Now with most firewalls your outside subnet cannot be the same as your inside subnet, which is fine if you are using NAT but i dont want to NAT. I need all of my servers to remain with their public ip addresses.
So what is the ideal way to setup something like this? Request my ISP give me a /30 for the ASA outside interface or something? And then ask them to route my /24 through the /30 new subnet?

View 3 Replies View RelatedCisco Licensing
May 16, 2007From the posts in this forum it would appear that a number of forumites are colocation service providers and web hosters that use Cisco gear.
I was reviewing the Cisco End User License Agreement that was included in the router box. Under the General Limitations section, "Customer shall have no right, and Customer specifically agrees not to:", item (iv) states, "use or permit the Software to be used to perform services for third parties, whether on a service bureau basis or time sharing basis or otherwise, without the express written authorization of Cisco".
Does this mean that a service provider is required to acquire
a separate license similar to the Microsoft Service provider license?
