How can ftp service on non-standard port be load balanced using Cisco ACE.

How can ftp service on non-standard port be load balanced using Cisco ACE.For example ftp service required on tcp 2000 port

Hi Samarjit,
you can do this by specifying the port number in the class map that you create . Please find the below mentioend config guide where you can specify the tcp/udp port , range or ports or even the wild card to match the port.

Adding a 2nd WFE to a Production Farm - Load balanced using F5 Virtual IPs

Hello all,
In much reading I haven't been able to find a more or less straight answer to this question: I have a small-ish SharePoint farm; 1 WFE, 1 App and a SQL cluster. I need to bring a 2nd web front end into the farm. What I am trying to find
out is, may I install the SharePoint bits and join the new web front end to the farm - without putting the web apps' IPs into my F5 pools - without adversely impacting the farm?
What I'm after is time to test the new web front end by redirecting my browser to it via my hosts file. Once I'm confident all is well, I would then configure WFE2 to have traffic forwarded to it through the F5. Is this a reasonable hope?
Thanks in advance for any advice you might provide

Yes, that will work.
Having an extra WFE that isn't included in your load balancer is actually a fairly common practice when you use it as a dedicated crawl target, there' no impact to having it there unused for a while.
Thanks very much for confirming; I appreciate that!

Load balancing using GLBP

Dear All,
I need to built a scenario where i am using two ISP's for redundancy for my internal network and at the same time wants to load balance in such a way that my first packet going outside the network (using NAT) goes from first ISP's public ip address and second packet going outside the network (using NAT) goes from second ISP's public ip address.
Need your help
Thank You

Hello
I tried to lab this up - I managed to use a first hop protocol (hrsp) to a redundant HRSP & NAT configuration - however I have tried GLBP and at present not been successful in getting it to work-

Load balancing using multiple default routes

Hi Guys,
I just want to ask does creating multiple default routes on my router provides load-balancing on my WAN side? As far as i know, for example if I have two default routes on my router and let say I have two users connecting to the internet, the first one might go to the first WAN link while the second user might go to the second WAN link.
Thank you so much
Rex

there are the difference between, load balancing and load sharing..which we need to understand.
load sharing means you have 2 users, user A and User B, user A wants to use ISP1 and user B wants to use ISP2. this is called load sharing. and can be achieved via PBR (Policy based routing).
we should not try to use load balancing for Internet traffic with 2 different ISPs.

Load-balancing using ServerIrons or NetApp Netcaches

          Dear all,
          From a cursory search, this one has been asked loads of times, but I can't find
          an answer....
          We're adding a Weblogic cluster into a resilient environment which has Netcache
          boxes doing reverse proxy and content caching, and Foundry ServerIrons doing the
          load-balancing. We could add in a pair of Apache servers load-balanced by the
          serverIrons and a pair of weblogic boxes in a cluster. However, this is not only
          a bit of overkill, but also adds quite a bit of latency to requests. We also
          already have the Netcache boxes. So, we want to get rid of Apache, and use a
          proposed 3 tier environment:
          Netcache
          |
          | (possibly via a serverIron)
          v
          Weblogic Cluster
          |
          |
          v
          Oracle
          Will this work? Does anyone have any experience extracting the session ID on
          a serverIron (or even on a netcache itself)? Has anyone found a way of doing
          session failover using a serverIron?
          Words of wisdom are needed for a flagging technical consultant...
          Thanks

Load Balancing using Virtual IP on DMZ interface of 5520 ASA

We want to achieve a load balancing scenario using Virtual IP on DMZ interface on a Cisco ASA 5520.
The IPs we are going to use on DMZ are 10.15.1.2 and 10.15.1.3
These IPs are going to be NATted to all inside IPs.
Lets say our outside IP is X.X.X.X
This IP points to 10.15.1.2 and 10.15.1.3 with .2 being the primary and .3 being the secondary.
When I hit the outside IP, it should point me to .2 and that .2 should take me to the inside IPs.
I need configuration assistance with that.

Hi Pratik,
The ASA does not support having 1 global/translated IP address on the outside mapped to multiple local/real IP addresses on the DMZ. If it did, the ASA would have no way of deciding if traffic destined to X.X.X.X is really meant for 10.15.1.2 or 10.15.1.3. For this scenario, you should use a dedicated load balancer or a router that supports policy-based routing.

CSM - Load balance using Server CPU

Hi
I have a customer who requires the load-balancing prediction
algorithm to be based on the CPU level of the Server. So the server with the least CPU is chosen at the laod-balancing stage.
Is there a way to do this?
Thanks James

Hi James
With CSM the only option is DFP (Dynamic feed back protocol). If your application vendor provides DFP agents (which is very unlikely) for the application then these agents can be installed on App servers for the desired purpose.

With ACE you can use SNMP based probes to achieve what you are looking for.

Firewall Load Balance using bridged mode ACE

Dear Folks,
I 'd like to load balance 2 ASA using 3 ACE [ Inside,outside,dmz network zone]
I 've seen sample configuration, all of them are running the ACE in the route mode, and asa are running in route mode
Would it be possible to run the ACE in the bridge Mode, because the ip subneted problem, We don't have enough to split,,
by the way if possible,All server that install behind ACE, what is default gateway should Server Point to [ in our case we have 2 independent firewall ] should I create the VIP for both firewall ? or should I just simply set the server's gateway to BVI interface, ?
Please Help Thanks

Thank you very much Gilles,
You 're the man. ;-)
Another question in my case I try to load balance 3 interface firewall [inside,outside,dmz] in order to make the packet return the same firewall it has passed earlier,
What kind of hashing technique do I need to use and Do i need to use mac sticky command ???
I tried to find some configuration sample from cisco website , but i only found with only 2 interface with ACE running source hash and destination hash in each ends,
Thank you very much

Site not accessible from the Load balanced web front end server - sharepoint 2010

I have a production environment with 2 WFE's(sp-wfe1 & sp-wfe2), 2 APP's and 2 SQL clustered VM's.
2 WFE's are load balanced using hardware load balancer.
An A-Record(PORTAL) is created in DNS for the virtual IP of the load balancer which points to the 2 WFE's.
A web application is created on the WFE's on port 80.
alternative access mapping is configured and the load balanced record "http://PORTAL" is used under the default zone.
Under IIS I have edited the bindings for the sharepoint site at port 80 and added the HOSTNAME as PORTAL.
Result: The site is accessible from outside the server and works fine.
ISSUE: The site is not accessible within the WFE's(sp-wfe1 & sp-wfe2).
When I browse the site from the WFE's server it ask for the credentials and when I enter the credentials and click OK it ask the credentials again and again and in the end displays a blank page.
Kindly help me in this issue because I am clueless and couldn't find anything helpful on the internet.

Mudassar

Lync 2013 Enterprise load balancing on the front end and edge pool

Hi,
I am setting up a Lync 2013 Enterprise deployment consisting of a Front End pool (x2 FE servers) and an Edge pool (x2 Edge servers). I'm seeing some conflicting advice regarding load balancing using hardware or DNS for the front end and the edge.
On the front end I have 2 internal DNS records 'lyncfepool1.contoso.local' each of which map to one of the IPs of the FE servers. I've used my details to populate the Detailed Design Planner excel spreadsheet and am told that I require a HLB to load
balance my front end pool. I'm aware of the need to load balance HTTPS traffic internally (which will be done by TMG) however other traffic to the front end (SIP, etc) can be balanced by DNS only, and not require a HLB?
Can someone clarify the front end requirement?
Also - looking now at the edge pool - this site again have two edge servers in a pool. We are using a total of six private IP addresses, two per edge service (2 x av.contoso.com, 2 x sip.contoso.com and 2 x webcon.contoso.com). These will be
NAT'ed by the external firewall and directed to the respective external (DMZ) IP addresses on the Edge servers on port 443. I know this isn't true roundrobin due to the intelligence of the Lync client when connecting (in that the Lync client will connect
to one of the public IPs and if it can't connect, it will know to connect to the other service IP), however I want to clarify this set up, particularly the need to direct the external public IP traffic at the DMZ Edge IP specified in the topology builder.
I've attached a basic diagram of the external/DMZ/Edge side which hopefully helps with this question
Persevere, Persevere, Per..

That is because you will always need HLB for a front-end server since it hosts the Lync webservices which use HTTP/HTTPS traffic.
The description on the calculation tool also describes this correctly:
Supports Standard and Enterprise pools (up to 12 nodes), with pure device-based load balancing or a combination of DNS load balancing and device-based load balancing (for
Lync web services)
You can use either Hardware or DNS loadbalancing for SIP traffic only, but you will always need a HLB for the webservices. Both are applicable for the Front-End so you have either
full HLB for both SIP and HTTP(S) traffic
DNS LB for SIP traffic and HLB for HTTP(S) traffic
Hope this is more clear :-)

Why do I have to overide internal Lyncpool FQDN when using hardware load balancing

Hi!
As the title says, why do I need to override the FQDN when using HLB? Why can't I just change the DNS entry of lyncpool01.domain.com to point to the HLB?
Thanks!

You'd want to override it because there are non-HTTP/HTTPS ports involved that are better load balanced using DNS.

http://technet.microsoft.com/en-us/library/gg615011.aspx
If you want to use HLB for all internal ports, then you wouldn't necessarily need to override this.

Hardware or Software Load Balancer

Hi all,
We're looking to have two OHS servers at the top layer which we then want to load balance using a DNS Alias. Does anyone have any recommendations or useful reading materials on choosing between software and hardware load balancers? I've seen and maintained Hyperion implementations that successfully using both, but would like to understand the pros/cons of each approach.
Also, does anyone know of any recommendations from Oracle on which approach with Hyperion / configuration recommendations when using Load balancers? The EPM High Availability guide 11.1.2.1 doesn't say much about load balancers sitting above the OHS layer
Thanks
Nick

Hi Nick,
The big problem with round-robin DNS is if one of your OHS nodes goes down every other user will head a bad URL. A hardware load balancer when setup properly will have much more intelligence and can sense if a site is down and automatically send all requests to the online node. Higher end hardware load balancers usually offer features like SSL Offloading and content compression.
This being said there are real costs for hardware load balancer which can run into the 10's of thousands of dollars if not hundreds of thousands of dollars.
You may also want to review the content available at: http://www.loadbalancing.org/
If you are looking for something in between round-robin DNS and a true hardware load balancer take a look at Linux LVS at: http://www.linuxvirtualserver.org/ -- this does require a bit of linux knowledge.
