I'm researching hardware alternatives to the Foundry switches we currently employ in our DCs. I'm focusing in on the Cisco 3750G-24TS, which seems to cover all the bases I need from a hardware standpoint. What I'm looking for from this crowd is any information they can share about that switch from a service & reliability perspective, especially how Cisco has treated you when you run into problems with the devices.
View 14 RepliesI used so far Nortel switches like Nortel 4550T-PWR, recently few of them died and since they have only 1 year of warranty i'm looking into other options.
To Nortel is this Cisco comparable model Catalyst 3750 (p/n: WS-C3750-48TS-S) or this Catalyst 3560 48 10/100 + 4 SFP IPB Image(p/n: WS-C3560-48TS-S) ? If is some other model please let me know, and i got around 20 nortel switches 2xxx, 4xxx and 5xxx series and at at least once a year one dies is that normal? They are properly installed in server rooms so there is no overheat issue.
And how much warranty Cisco gives on their switches which are comparable to 4xxx and 5xxx series of Nortel.
My 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,
Does anyone know a way to put Virtuozzo on a Nehalem node?
Secondly, do these Nehalem's have a great increase in Virtualization like they say, versus the 5450 series?
I would like to know this just for general reference. Because in a VPS to VPS envoironment are these really better? If there's no solution to this I guess the best solution would be a 7xxx 16 core Xeon, what's your opinions on that?
about thei5 and i7 cpu,
what series of xeon are the same as they are?
Can anyone give any real world numbers as to what each model of the Juniper-J series router is capable of? How much do these routers cost, and where is the best place to get them from?
View 14 Replies View RelatedIn one of our racks, we now just have two Procurve (J4900B) switches, and run software firewalls on our CentOS servers. We are now looking towards a hardware firewall to ease managment and reduce load on our servers.
One of our suppliers reccomends the SSG140 from Juniper, and it seems to cover our needs. The SSG320 however seems to have more features, like layer3 routing. Could this device replace our Procurve switches, and act as a firewall/switch?
Anyone familiar with these devices and have some input on what to choose? How does the anti-ddos and bruteforce attack functions work out, do they hold up? Anyone tested the Deep Inpspection Signature module? Is it worth having for a ISP/Webhost?
any experience and feedback on Juniper J-series routers?

Anyone know anything about cisco pix 501s? i need help setting one up if anyone can give me a hand.
View 14 Replies View RelatedI 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?
I 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 ?
We 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
I 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?
I 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.
after 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.

I'm trying to learn about network. I bought Cisco 2950 for testing. I set it up and finding out the way to cap its ports at 20Mbps or 50Mbps. Do you know what command or how to do this?
Also what command to check the port speed or to uncap the port?

What is the difference between the Cisco PIX and Cisco ASA Firewall Systems?
Also which firewall do you guys recommend for a rack of servers
I 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?
My 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?
whether I can grant a specific vlan priority over all other traffic..and if so does anyone know an appropriate site where I can find documentation on how to do so?
