HP 2910al, Summit X350, Juniper EX3200, Netgear Gs724at
Aug 23, 2009
Looking to upgrade to a new switch and have the following in mind. Budget is around 1-2k. We're pushing 500mbps upstream so i want to make sure that the unit can handle that well. Lots of full speed traffic between servers too.
No fancy features required, and the only need is port trunking, which all of these have.
I look at the specs for latency and pps, but I'm not sure if you can trust these figures.
Anyone have experience with the following.
HP Procurve 2910al-24
$1430
latency <2.9us
131 Mpps
176 Gbps
Bonus: 10Gb capability with expansion module
Extreme Networks Summit x350
$1300
latency < ?
65 Mpps
88 Gbps
Bonus: 10Gb capability with expansion module
Juniper Juniper EX3200-24T
$1800
latency < ?
65 Mpps
88Gbps
Bonus: 10Gb capability with expansion module
Bonus: 8 ports are POE
Netgear GS724AT
$350
latency <3us
??? Mpps
48Gbps

Anyone using an Extreme Networks Summit x450a for aggregation/edge? I'm looking for a switch to handle aggregating a few racks (~10) and provide bandwidth accounting, rate limiting, and port filtering by IP address (not port). Any reviews?

Having a slight problem working with one of our Extreme Summit 48 (ugh) switches - I've figured out most of the basics, but I can't seem to find any way to add a secondary IP address to a VLAN! This, I would have thought, would be a pretty basic feature to have. Typing "config vlan [vlanname] ipaddress 1.2.3.4/24" works for setting the primary IP, but I can't figure out how to add any more - and doing the command again just overwrites the first one.
So... does anyone have any tricks up their sleeve, or is this something that Extreme neglected to add to this model switch?

I just picked up a Summit 24e3 and found it that the extremeware inside has no SSH (OMG) and Web interface. I am wondering if anybody got a firmware laying around that I may able to download off.

i am using NetGear GS748T Switch and having problem with it.
Currently NetGear GS748T Switch is providing all clients 1000Mbit connection.
unfortunately i don't have the software and this is my first time using NetGear GS748T Switch.
how to control my switch and limit my clients connection.
NetGear GS748T Switch is accepting 10/100/1000Mbit, currently everyone have 1000Mbit. if any idea how to control / limit it, please let me know.
and one more question about bandwidth usage, what should i install to see each client bandwidth usage ?

A month or so I bought a cheap NetGear FSM762 managed switch of eBay.
Its perfect for our needs as its only ever going to have 20 low traffic servers plugged in. When I first received it I tried it on my local home network and was able to login to the webadmin, telnet and serial/console perfectly, now I have plugged it into a live setup, added the IPs to it (rather than DHCP on my home setup) and the bugger just doesnt want to load up telnet or webadmin but serial/console is working perfectly.
If I go to the webadmin I get: Bad Request (Invalid Hostname). Last night we moved all our servers to a new rack and we got the error above. Before this the page wouldnt load at all

I need to protect about 80 servers from certain attacks some of them are being victim of. Altogether, these servers use about 200Mbps being almost all of them webservers. The last time, one of them was a victim of a DDoS attack which made all the rest get some packet loss (because this attack was consuming all the bandwidth we had available).
I was looking at Juniper solutions, however I get a bit confused with all the products they have to offer. First, I was looking at IDP series, but they seem a bit pricey and I believe I donīt need all those IDP functions those devices are capable of. NetScreen is also too expensive for me. Iīm looking at a budget of 10.000$ aprox.
I found SRX series and after taking a look at SRX240 and SRX650 specs [url] those firewall numbers seem very nice and perfect for my problem. Would this be a wise choice? This device would act also as the main router for our racks. Please let me know if there are other recommendations that fit the specified budget (10K).

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?

Does anyone have any experience running Juniper SSG-550 firewalls in a high-traffic hosting environment?
I run network operations for a hosting provider in Australia. We currently have two J4350s running as border routers, and we are looking at putting two Juniper SSG-550s behind the border routers to do stateful firewalling / NAT.
We'll be using active/active NSRP on the SSGs for load balancing and failover.
My concern is that these devices may not be able to handle our traffic load. They have a hard-set limit of 256,000 "concurrent sessions" which may not be enough for us in peak times. Almost all of our traffic is HTTP though, so I would imagine sessions would timeout quite quickly?

In 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?

I've been reading and searching on here as much as I can to try to help me in making a decision, unfortunately when I think I know what to do, I read something else and get confused again.
We are in the process of moving networks within our datacenter and will have 2 drops coming into our half-cabinet. We have about 7 servers in there, some for our own use and some for clients. In all cases, we manage the servers and are the only ones with root access (no need for VLANs for the purpose of protecting IPs etc).
We currently have a single drop and use an HP procurve 2524 layer2 switch that has been in there for over 6 years and never had a single hiccup. We also don't push much traffic at all though. Under 5mbps combined.
My question though is this: moving to the new network we will have 2 drops that are set up as HSRP on their end (upstream of me, I don't have to worry about having two switches). In order to use the dual feeds, we will need a Layer3 switch. One feed will be active, the other is not, both are connected to the switch via a VLAN and provide a gateway for VLAN2 to use. I have never used a layer3 switch, though I'm not *too* concerned since I don't expect we'll be doing anything too complex. My understanding is that one VLAN (VLAN1) will be set up with an IP address assigned to each drop and that VLAN1 will create a gateway for VLAN2. The second VLAN (VLAN2) will be all our "inside" client IPs that will then route through VLAN1.
I was briefly checking out the cisco 3750, but I think it's overkill...? I don't want to spend too much money, since I don't think we need any complex setups, at the same time, I don't want to waste money by buying something that won't work efficiently down the road.
My immediate short-list is now an HP procurve 2610, an HP procurve 3500 J9470A (not the YL), and a Cisco 3560 24-TS.
Of course, then someone mentioned Juniper (whom I have zero experience with either) and hence the title to my thread... I'm thoroughly confused. I was looking at the EX3200-24T.
Ok, so if I have to boil this down to some simple requirements/thoughts... here goes:
1. I only need 24 ports for now.
2. I use SNMP currently to monitor usage for clients (and overall)
3. I like HPs and have used them for layer2, I like their lifetime warranty and software availability
4. I don't have direct experience with Cisco at all.
5. Aside from routing from one VLAN (provider side) to another VLAN (my side), I don't think I need any other special features (hence the hp 2610 being ok I think, since it offers "lite layer3")
6. Some people say HP is great for layer2 but not for layer3? Now I dont' know what to think.
7. Currently use about 2mbps and might jump to 3 or 4mbps, but don't have major needs. I'd like for this switch to be able to last me a while though... so maybe 20~40mbps+? (but still not the hundreds of mbps that others here push
8. If possible, I'd LIKE to limit some servers to 1mbps or 2mbps on a per-port basis... but this is not a hard requirement. (I think this takes the 2610 out).
Budget: I like the $500 price tag of the 2610, but can spend the $1500~$2000 for the HP 3500, Cisco 3560, or Juniper. I would just rather not, if the price/features are not justifiable.
Hopefully I've provided enough information for someone to offer their insight? I think a few strategic key points or questions from someone with more experience might be what I need to help me bust through the "too many choices" fog and end up with the best switch for my situation...

I am tried of not finding a good documentation on now to configure netscreen-25 firewall.
This is the current setup;
Ethernet Drop -> Netscreen (connected via straight RJ-45)
NetScreen -> Switch (Connected via cross-over cable)
This is the what I want to be able to do...
I am assigned a 76.36.57.32/27 subnet
Netmask 255.255.255.224
Gateway 76.36.57.33
1) Make Netscreen accessible via IP 76.36.57.34 for remote management.
2) I dont want netscreen to assign IPs for my wired devices because I've already set all their IPs and those are the ones I want to use.
Now, I did read the manual [url] and went to Network -> Interfaces -> Ethernet 1 Trust *edit* and in the "IP address" box I typed 76.36.57.34 and netmask "/27".
In the "Manage IP" box, I typed 76.36.57.39/27 according to the manual.
After doing all that, I cant access any of my "wired" devices behind firewall and neither can I access the firewall itself with the IP I assigned.

we have this Juniper SSG5 firewall, our very first Juniper and wanted to use it.
While I am able to use it in NAT mode, I have been unsuccessful to use it in route mode.
We have Public IPs from the same segment and I wanted to use it with the firewall but it appears that I can't assign IPs for each port if the IP is from the same segment.
Does it mean that we can't use it other than in NAT mode?
What we want to accomplish is to have one of IPs to act as gateway and filter or route in/out traffic to/from our other IPs.

We are searching a firewall for our small colocation.
We have chosen the Juniper SSG 520/550 or a Cisco ASA 5520 (eventually the 5540).
We want primaly filter ddos attacks on our webservers (bot-network, attacking a domain, port 80) and syn flood attacks (port 80).
Do you have real experience with the Juniper or Cisco devices?
Can we integrate such device in the fellowing network design:
(where to put the firewall ?)
- Uplink 1gbit datacenter -> our HP Procurve gigabit switch
- HP Procurve switch -> Servers
We are using /30 as eth0 "bridged", and /29 /28 /27 "routed" over eth0.
I would prefer a "live analysis" of our traffic. Is that possible?

I've been looking at these two Firewalls for a quite some time and I am not sure which one I should go with. Price is not a factor since both are around the same price range.
The firewall is going to be in between my DROP and LAYER3 Switch.
So...FastE -> Firewall -> Layer3
As you can see, I dont want any fancy VLAN stuff or anything like that since my switch can take care of all that. I just want a firewall which is easy to configure and manage and has DDoS protection built-in.
If you have any other hardware based firewalls in the price range of ASA 5505 and Netscreen 5GT then I would want to hear about those as well.

I have a SSG-320M I manage, and would like to know if I can block traffic to our web servers based on the user agent hitting us? I know user agents that keep using more and more IP addresses to crawl us, one already taking up some 30 or 40 addresses under my policies and its a pain to identify these by hand and keep updating the firewall every few days to add new IP addresses for them. Is there somewhere I can add part of the user agent I do not want to ever see again? Right now I do this by having a policy at the top saying "BadBotsGroup" is denied. But I want to deny anyone with a user agent "OneUserAgent" or "SecondUserAgent"
It seems so important and simple, but I do not see anything about being able to do this. Thanks for help and pointers. Right now we have special code at the top of our sites that blocks these bots, but I would much rather do it in one location at the firewall.

to build a new 10GE network and have received offers from Juniper and Cisco distributors.
Juniper seems to be a bit more expensive. It was our first choice at the beginning untill we saw many big ISP's using cisco 6509 with SUP720-3BXL for routing.
Is there anyone with experience on both products? How about support for both of these?
