to 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.
I 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!
I 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?
I 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?)
Is there such a switch?
Do cisco do a 24 port 1000Mbs switch that you can control each port speed through a web based software?
where I can get the best price for HP switches? Looking for 1x2848 and 1x2650

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
basic 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.
Does 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.
We'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.
I 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.
I 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.
I've read that Virtuozzo 4.0 supported ipv6. I'm having problems finding anything to help setup the node for ipv6. I can't anything on the web except for some people talking about how to disable ipv6. So I was just wondering if anyone else has seen anything.
Edit: I don't think I posted in the correct section. Opps. Could a moderator move this to the right section?
we would like to extend our services with providing IPv6 for dedicated servers.
Our colo will provide us /48.
Am pretty new to IPv6. Can anobydy give some hints about IPv6 addressing for such scenario.
How should we cut that /48? How much IPs shoud I provide to every server?
Any real hosting world scenarios?
If you took every dns A record that exists for an ipv4, converted it to an AAAA ipv6 address record, what would the disk space difference be amongst every computer that hosts a dns server today?
View 1 Replies View RelatedI did a little research about availability of dedicated servers with native IPv6 and my results are... Well, let's just say that they are worse than I expected them to be.
Only providers that I found (with IPv6 carriers in brackets) are:
- OVH, FR (Teleglobe, Global Crossing),
- CoreIX, UK (Tiscali, Teleglobe),
- Goscomb, UK (NTT/Verio, Global Crossing),
- FDCServers, US (NTT/Verio, Hurricane Electric).
There is also LeaseWeb (and I found one IPv6 server running on their network), but I didn't find any information regarding IPv6 on their page.
If you know others, please update the list (with IPv6 transit providers if you know them, no peering/IX please).
As you can see, there are at least 5 carriers who provide native IPv6. What bothers me is the fact that most of the US providers use NTT/Verio, Global Crossing or both of them in their BGP mix. Why don't they enable IPv6 connectivity? All their hardware supports it as IPv6 isn't anything new, so I really don't see a reason why they don't do it... Anyone want to enlight me?
As this isn't 'offers request' thread, I guess it wouldn't be against the rules for providers to say 'we do IPv6'
Using CentOS server hosted with The Planet.
When I do an ifconfig I see a regular IP as well as an IPv6 one.
Does this mean my server is accessible via IPv6 as well, and would that bypass any firewall I have set on the regular IP? I noticed theres a ip6tables as well but I don't have it started. I'm fairly new to iptables in general so I'm not touching ipv6 now, unless I have to. Would it be safe to just block everything through ipv6 or would that be bad?
I'm kind of interested in learning more about IPv6 and eventually actually supporting it, but for now I rather not until I learn more about it.
In terms of dedicated servers how does this work? Is this something you can ask for, and is there any advantage to having it? Is it also possible to have an IPv4 AND IPv6 on same server?

View 3 Replies View RelatedCan you make a recommendation for a switch-based L3 router which can
- hold a moderate number of routes (interface routes, a few hundred statics + default)
- OSPF and BGP
- MST
- 1024 layer-3 dot1q subinterfaces (or maybe VLAN interfaces)
with
+ traffic policing in and out per subinterface/vlan
+ VRRP/HSRP/NSRP
- IPv4 & IPv6 native
- 2x GigE ports
- Not tip-over under 1gbps DDoS towards a VLAN interface.
I've been using 3560Gs, but they seem to lack the output traffic policing. I'd prefer to have subinterfaces which don't run spanning-tree, versus Vlan Interfaces to a trunk interface which runs spanning-tree. These switches sit at the L3 boundary between two L2 networks.
Cost is a big factor; but I also must carry vendor licenses & support contract, if the vendor asserts that not doing so is illegal in US.
I'm running plesk 12.0.18 on centOS 6.6 and I have some problems with ipv6 support for a domain. This is what I see in my apache logs for that domain:
2001:8d8:90b:c900::2a:19d1 - - [29/Jun/2015:17:44:55 +0200] "GET /hello.html HTTP/1.0" 404 1208 "-" "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)"
2001:8d8:90b:c900::2a:19d1 - - [29/Jun/2015:17:49:39 +0200] "GET /hello.html HTTP/1.0" 200 384 "-" "curl/7.19.7 (x86_64-redhat-linux-gnu) libcurl/7.19.7 NSS/3.16.1 Basic ECC zlib/1.2.3 libidn/1.18 libssh2/1.4.2"
2001:8d8:90b:c900::2a:19d1 is the ipv6 from my server, and it appears there because of nginx working as reverse proxy.
As you can see, facebook can't get /hello.html (404 response), but I can get it from another server using curl (200 response). I tried disabling nginx and this is what I see now:
2a03:2880:2110:dff3:face:b00c:0:1 - - [29/Jun/2015:17:55:11 +0200] "GET /hello.html HTTP/1.1" 404 1208 "-" "facebookexternalhit/1.1 (+http://www.facebook.com/externalhit_uatext.php)"

Still not able to get /hello.html. This is a problem for me because I can't share anything on facebook, since their bot can't find anything on my site.
I've already configured ipv6 for my domain.
Plesk Firewall has no effect on IPv6?
I am writing today regarding the Plesk Firewall. It seemed to be pretty handy for quickly blocking troublesome users from *replace-with-whatever-IP-block-is-giving-you-trouble*. Yet I am unable to block IPv6 addresses, and the fire wall seems to let some blocked IPv4s right in. I did not see any distinction as to v4 or v6 in the Firewall dialog for adding custom rules, so...
The question is...
(1) Is the Plesk Firewall *supposed* to apply rules to IPv6 by default?
If yes...
(2) Is there a setting or a switch that has to be configured for this to work?
If yes...
(3) Where are said configuration options located?
Okay, when I run /sbin/ip6tables -L (CentOS) I get output that resembles the iptables (no 6) output, only... what, converted to IP6? Not sure. Example output:
DROP tcp ::ffff:31.0.0.0/104 ::/0 tcp dpts:1:10000
In that particular instance I added a drop for the 31.0.0.0/8 block (using the Plesk Firewall interface), in order to create the script that's loaded into iptables (and ip6tables as well, apparently) when one elects to "Apply Configuration". It worked great, executed perfectly, and the iptables output list output looked to be (and remember, I have grossly insufficient background knowledge in this area) accurate.
Yet at the time of this writing I can see via live traffic monitor that an address in the 31.0.0.0/8 block (IPv4) is pounding away at a website. This is curious, as the live traffic monitor indicates an IPv4 address. So... can an IPv4 address be detected and recorded from a host that is only able to connect via IPv6? While an interesting question, I was more concerned with just blocking the IPv6 address and get more academic with it later.
But this raises another question; why would Plesk populate ip6tables and not provide an interface to actually submit IPv6 addresses.
I've been happily banning ip's using the output from
netstat -plan|grep :80|awk {'print $5'}|cut -d: -f 1|sort|uniq -c|sort -nk 1
for over a year now, with iptables. However recently, after upgrading to apache 2.2, the connections in netstat get listed as ipv6. A row can look like this for example:
tcp6 0 0 ::ffff:12.123.123.123:80 ::ffff:12.123.12.:12382 ESTABLISHED-
(actual ip addresses changed)
As you can see, the remote ip address isn't complete, it's cut off, so the script used to sum up connections and insert into iptables isnt doing anything.
