• BONES of PIX v6.3: Load Balancing Configuration

  Using the new feature of balancing by OSPF, is it possible to create a parallel table of the PIX to simulate a "dynamic load balancing environment"? Please explain why or not.

  If the answer is no, then, is it possible to create an environment of load balancing 'static '? How would this work? advantages and disadvantages?

  Kind regards.

  Fix... You need something in front of and behind the Pix to ensure that a session is maintained through the same Pix. This can also be done by NAT.

• PIX / ASA - OSPF load balancing

  Hello

  I read the balance a route via OSPF equal cost load the PIX. It will send packages via per package, or is there another method for distibuting the traffic to the break following equal cost?

  Thank you!!

  Hello Lawrence,.

  PIX 6.3 now supports the NLB using OSPF only (up to 3 default routes)

  The PIX can receive up to 3 doors by default (all the same metric) 3 different routes of entry, and

  balance the load on a per destination basis. Currently, there is no way the PIX to

  determine which carries a package will be sent to. You cannot currently use static routes

  for load balancing.

  The used hash algorithm is not simple, it is very difficult to determine which

  Route (next hop) a package will be given an IP Source and Destination pair. Basically,.

  the PIX takes the source and destination IPs (two 32-bit numbers) and axe in one

  16-bit unique number. Then the number of 16-bit (0x0000 - 0xFFFF) is divided into thirds.

  The first 1/3 goes to the door of entry 1, the next 1/3 goes to the door of entry 2, and the last 1/3 goes to

  Gateway 3.

  I hope this helps! If Yes, please rate.

  Thank you

• Load balancing question

  Hi all

  I have a question on the load balancing between several hosts of session.

  We have 6 Guest session, I created a managed with a specifik balancing application rule "Session desktop host advanced remotely. last Friday, he started a few problems, but we have not made any changes.

  the fist session host server had 71 active users and other servers were only 30.

  How is that possible?

  Do I have to put the rule on each server load balancing?

  Hello Sander,

  You must apply the rule individually for each RDSH of load balancing. Not on the managed desktop application. In our configuration, this does not work then maybe of the same counts for you.

• Cisco RV016 failover & load balance Multi WAN question

  Hello

  I think the RV016 is the camera to buy for our small building, but I'm a bit confused in the manual if my scheduled configuration is possible, so if you could confirm if this is possible I would appreciate it.

  We have a leased line as our main connection (lets call him WAN1). If this connection is not available, I don't want to load balance to any other network WAN.

  We have 2 netgear 4G devices identical (we'll call WAN 2 and 3 WAN). If the leased line is not available, I would like to then load balance these two WAN connections.

  Then I have a final connection, WAN4 as a slow adsl line. I don't know right now if I want to load balance this WAN1 or just have it as a backup to WAN2 and WAN3 failure (WAN2 and WAN3 have a 20 GB data limit each on their monthly allowance of the contract, if the leased line is down for more than a couple of days, what is unfortunately already happened) (then we reached this limit and then there is charged with extremely expensive data or just use the only ADSL)

  In any case, it's normal, I want to balance the load. I want to only load balance WAN3 and WAN2 WAN1 fails.

  Anyone know if this is possible? If not, is there any other similar device which would be appropriate?

  Thank you

  Ben

  Hi Bencarroll01,

  With RV016 you can get what you need.

  RV016 supports up to 7 WAN connection, and there are two mode of operation

  • Swing smart (Auto Mode): This option allows you to balance traffic between all interfaces increase the available bandwidth. The router balance traffic between the weighted alternating interfaces.
  • Group of IP (by users): Select this option for trafficking group on each WAN interface by levels of priority or classes of service (CoS). With this feature, you can ensure the bandwidth and a more high priority for specified services and users. All traffic that is not added to the IP group uses Intelligent balancing mode. To specify the services and users, click modify for the WAN interface and then add the entries of binding protocol for each service, IP address or IP address range.

  For our case, we must have RV016 configured with IP Group(By User), so in this case, we can configure binding protocol that we can specify and force all traffic from any IP address of the local network outside through WAN1. and any other WAN connection they always towards the TOP but not the traffic passing through them

  Now if WAN1 is down, immediately the rule to redirect traffic WAN 1 will be disabled and all traffic will pass through the rest of the WAN connection

  After that if the WAN1 is once again the binding protocol rule will be active again and again all the traffic will be done by WAN 1

  Please let me know if you have any other questions

• OSPF load balancing

  Hello

  Does anyone know how to deploy load balancing in OSPF area 0?

  Any suggestion for documentation would be apreciated.

  Thanks in advance for your help

  Hello

  OSPF is only the equal cost load balancing, so you must have two channels with equal to the destination charges.

  This command must also be set to more than one:

  maximum-paths

  under router ospf configuration.

  I think you also need ip cef enabled.

  See this link for more information:

• Question of balance of load on services deployed in two slaves

  Case:
  One master: 192.172.1.1
  Two slaves: 192.172.2.1/192.172.2.2
  There are service deployed in (192.172.2.1) slave1 and slave2 (192.172.2.2). A service will call the Service B, which is also deployed in slave1 and slave2.
  
  Condition:
  If I s as Department_A tmshutdown in slave1, there is a living as Department_A in slave2.
  
  Question:
  Now there's A service requests in slave2. If service B in slave1 will be called by A service in slave2 or not?
  
  My experience proves it of true. However, in my mind, the request to serve a slave2 only service B in slave1 slave2 not call. Is this wrong?
  
  Thanks for your kindly reply.

  Bill,

  If the service is available only on the B service and slave2 is available on both slave1 and slave2, service one can always call the B service on both slave 1 and slave 2 instances. A local idle service will always be perferred to a remote service, but if the local servers offering a B service are busy the system will also use remote servers.

  Each service has a charge associated with it as specified by the LOAD parameter in the UBBCONFIG * SERVICES section.  The default value is 50.  If some services are known to take longer that other services, an application can specify more load for long-term care services.

  The * section parameter NETLOAD MACHINES can be used to specify an additional charge to be added when calculating the cost of sending a request to a particular machine to another machine.  If NETLOAD is specified then Tuxedo will prefer the local machine to the remote machine by running the load balancer.

  Kind regards

• Load balancing ASA question - what IP I do direct clients too?

  I have 2 5520 with SSLVPN 50 user on each license. I want to use the VPN load-balancing feature. Must I send users to the address IP of Cluster? The documentation is not clear on this point.

  Thank you

  Justin

  That is right. You should have the VPN to connect on the LBS, not individual IP addresses cluster IP. Captain ASA will listen to connection requests to the IP cluster LB and based on the load either accepting the connection or automatically redirect to one of the ASAs Eve in the cluster. It must all be transparent to the user VPN connection.

• Windows Server 2008 R2 Network Load Balance question

  Hello

  I got my hooked VMs when a network load balancing in Windows Server 2008 R2 clustering.

  This only happens for Windows Server 2008 R2, Windows Server 2008 with SP2 is OK.

  And I use VMware ESXi 4, I don't know if this has been addressed in ESXi 4 U1.

  Can someone give some advice?

  Thank you very much

• RAC load balancing question

  We have added a third node of a cluster with two nodes on 11/7. Before the addition, expenses (via the OS uptime command or above) on the two first nodes were included between 20 and 40. The first node was the more active of the two, rarely fall below 30, but on both charges were very high. These first two nodes have two dual core CPU with 16 GB of RAM, who have six cases of db on each. The third node has two quad core CPU and 16 GB of RAM. We added only the busiest db on the third node, so there is only a single instance. We have added the third node to all remote to connect DB files tnsnames, with LOAD_BALANCE = yes. For the first week, Sunday 11/7 to Sunday 11/14, most incoming connections were still nodes 1 and 2. Connections have been made to node 3, but not as much as we would like. However, since this last Sunday 11/14, the majority of the connections are nodes 2 and 3. Rarely a connection will node 1. We can connect directly on node 1 with no problems. Nothing has changed over the weekend and nothing has been restarted. Is something that takes a while to 'calibrate' load balancing? Is there something that we can check or change to give a more balanced load? We are new on the PAP, so we are puzzled as to why it happened this way. Any guidance or advice is greatly appreciated.

  You must configure at the level load balancing server-side.

  (1) register all instances in any listener by setting local_listener and remote_listener of init parameters
  (2) CLB_GOAL set of each service, to set the expected duration of connections ("SHORT" for the pools of connections or "LONG" for forms)
  (3) set the GOAL of each services, updated the workload expected (FLOW for batch) or TIME of SERVICE for web sessions

• Correct settings to use Smart Connect and load balancing?

  Hi guys

  I have a question, the answer of which I was not able to find explicitly, so I hope a quick fix OK / not OK for you:

  I would use tri-band technology provides the R8000, i.e. to activate Smart Connect / load balancing. Is - it only works Ghzs 5 band, or the router can also connect clients on the 2 Ghz bands?

  If this is true, then I need to give the strip of 2, 4 GHz the SSID the same 5 Ghz band, correct?

  Otherwise, if it only works in the 5 Ghz bands, I could keep the SSID distinguishes?

  Thank you

  Balancing of resources between the two radios. 2, 4 GHz band vs a single radio, the two radio channels in the 5 GHz band.

• Nexus 1000v, UCS, and Microsoft NETWORK load balancing

  Hi all

  I have a client that implements a new Exchange 2010 environment. They have an obligation to configure load balancing for Client Access servers. The environment consists of VMware vShpere running on top of Cisco UCS blades with the Nexus 1000v dvSwitch.

  Everything I've read so far indicates that I must do the following:

  1 configure MS in Multicast mode load balancing (by selecting the IGMP protocol option).

  2. create a static ARP entry for the address of virtual cluster on the router for the subnet of the server.

  3. (maybe) configure a static MAC table entry on the router for the subnet of the server.

  3. (maybe) to disable the IGMP snooping on the VLAN appropriate in the Nexus 1000v.

  My questions are:

  1. any person running successfully a similar configuration?

  2 are there missing steps in the list above, or I shouldn't do?

  3. If I am disabling the snooping IGMP on the Nexus 1000v should I also disable it on the fabric of UCS interconnections and router?

  Thanks a lot for your time,.

  Aaron

  Aaron,

  The steps above you are correct, you need steps 1-4 to operate correctly.  Normally people will create a VLAN separate to their interfaces NLB/subnet, to prevent floods mcast uncessisary frameworks within the network.

  To answer your questions

  (1) I saw multiple clients run this configuration

  (2) the steps you are correct

  (3) you can't toggle the on UCS IGMP snooping.  It is enabled by default and not a configurable option.  There is no need to change anything within the UCS regarding MS NLB with the above procedure.  FYI - the ability to disable/enable the snooping IGMP on UCS is scheduled for a next version 2.1.

  
  
  This is the correct method untill the time we have the option of configuring static multicast mac entries on
  
  the Nexus 1000v.  If this is a feature you'd like, please open a TAC case and request for bug CSCtb93725 to be linked to your SR.
  
  This will give more "push" to our develpment team to prioritize this request.
  Hopefully some other customers can share their experience.

• ISE behind the load balancer

  I have a question about ISE profiling of the servers that are placed behind a load balancer:

  If you have an ISE environment where computers and users are be authenticated and restricted access Machine (MAR) is enabled (so that users can authenticate only on a machine already authenticated), the ISE servers up-to-date with all authentications of succesfull computer manipulated by other servers in the ISE?

  For example:

  There are 2 aircraft of ISE (ISE01 and ISE02) behind a load balancer.

  A user starts the computer and the computer authentication is managed by ISE01 (and the authentication is successful). For the moment, that the user logs on to this computer, the load balancer selects ISE02 to authenticate the user.

  ISE02 will be aware that the computer has been already properly authenticated on ISE01, so that users are able to connect? Or she refuses authentication of the user, because he thinks that the computer is not (yet) authenticated and Machine Access Restrictions is enabled?

  Kind regards

  Bert

  ISE servers are aware of all authentications of succesfull computer manipulated by other servers in the ISE?

  => N°

  they are independent servers that replicate that configuration.

  If a user must always authenticate with the same ISE.

  In addition, a load balancer kills profiling since profiling requires you to cover a portion of the traffic at the ISE

• Nexus1000V load balancing

  Hello

  could someone help me to clarify this...

  In our environment, we have a Nexus1000V. VEM is connected to two switches uplink. At this point neither mac-pinning or vPC - HM are used and nexus is running the default load balancing mechanism (source-mac). I see a mac-beating on the switches uplink to servers in the VCenter. If source-mac has been used should not the mac address of a virtual machine be persistent on a specific switch, assuming he is not moved to an another ESXi?

  We intend to change our port to link rising-profiles mac - pinning or vPC - HM. The documentation states that, in this case, the virtual machines are associated with an uplink of alternating. So, what is the use of the load balancing in this case? Load Balancing have effect only if good LACP is trained (stackable switches etc.)?

  One last question:

  If mac - pinning is used and a link fails, then all vm traffic will be sent to the second link. If the first link is displayed again, while traffic for virtual machines that have been associated with the first link, be moved to the first or the traffic will continue to flow on the second?

  Thank you in advance,

  Katerina

  Hi Katerina,

  I have configured my lab for "auto channel-group" and the two links are in a port channel.

  MEC considered the two uplinks as the same interface.

  Module # 4 N1K vem run vemcmd see the port
  The State of the link Admin LTL VSM Port PC - LTL SGID Vem Port Type
  19 Eth4/3 UP UP F / 1039 B * 0 vmnic2
  20 Eth4/4 UP UP F / 1039 B * 0 vmnic3
  49 UP UP FWD 0 0 vmk1 Veth9

  * SGID designates sup group ID

  After the release, Vmk1 traffic can take vmnic2 or vmnic3. N1k sees this as an outgoing interface port-channel. In order to avoid the beating of mac, we need to configure the two switchports upstream in a logical interface.

  Now, MAC pinning configured, run us the same command

  Module # 4 N1K vem run vemcmd see the port
  The State of the link Admin LTL VSM Port PC - LTL SGID Vem Port Type
  19 Eth4/3 UP UP F / 1040 B * 2 vmnic2
  20 Eth4/4 UP UP F / 1040 B * 3 vmnic3
  49 UP UP FWD 0 2 vmk1 Veth9

  vmnic2 and vmnic3 are considered two different outgoing interfaces. There is no switchport upstream requirements.

  HTH,

  Joe
