• RV042 load balancing problem

  We have two network connections coming into the office. One is a private Wan, and the other is a WAN on the internet. We have a RV042 router configured for load balancing. We have our private WAN which includes Exchange and 6 VPN Wan1. On WAN2, we have a public IP address and home workers. Both connections are 5 Mg T1s and both have the ability to access the internet but only wan2 has a public IP (76.x.x.x) were as WAN1 has a private IP address. (10.x.x.x).

  Were now the problem lies is our new website based on payroll, system does not support load balancing. We have on one hand stop when we do pay (Tower load balancing off.)

  Now is it possible to use our computers to pay only one side? change the host file maybe? Or force a certain MAC address of use only the WAN1 or is there a better router to achieve?

  Any help would be appreciated

  I don't have a RV042 and have had reference to the Administrator's guide:

  http://www.Cisco.com/en/us/docs/routers/CSBR/RV042/Admin/Guide/RV042_V10_UG_C-Web.PDF

  I hope these comments are useful. Perhaps you can comment and let me know if it works for you. Check balancing load and the binding protocol section.  These changes are disruptive... Please assume a failure during the change.  Not a long interruption, but the sessions at the same distance could be lowered.

  Out, you can use the protocol binding. This could cause some problems with the VPN client... you can try this after hours?

  For entrants, how customers and remote computers know the accounting software?  You are advertising this IP address via a link or another?

  If you are, then you can have a preference through one of the links.  If you advertise this IP address then you will not be able to provide a preference to a supplier of services on the other.

  Do please see the Administrator's guide and let me know your thoughts.  Sincere greetings and HTH,

• With view 5.1 load balancer

  Hey all,.

  I have a question about to lift our load balancing program and perform in our view environment 5.1.  I followed the article KB 2020913 to get our servers view running with SSL certificates.  I'm doing our load balancer in place and I keep getting errors in SSL certificate.  Here is a brief summary of our facility.  I have two servers to view (VCS1 and VCS2) connection with our internal certificate authority SSL certificates.  There is our program of load balancing.  When you use VMware View Client and go to the view.company.com address of the load balancer, I get "pipe in the certificate name is invalid or does not match.  I click on 'See the certificate' and it is to show the certificate of one of the connection view servers.  A I mess up something with the installation program, or have I missed an obvious solution?  Any help would be appreciated.

  Thank you

  -Kyle

  Hello

  It is the expected behavior. With SSL, the certificate name is checked by report specified by the client host name.

  There are two ways to deal with this. If you are using certificates with another subject of your load-balanced alias name, it all will work.

  for example if you have some certs on each connection to the server (or the Security Server) with the names cs1.myco.com and cs2.myco.com but customers do you think users will connect using a load-balanced alias view.myco.com, then by ensuring that each cert has another name of subject of view.myco.com then the hostname match control work.

  See KB. VMware.com/kb/2006751 for more information.

• Load balanced OAM servers

  I have 2 instances OAM, set up on 2 different machines, working with them through in a cluster. When I created a webgate 11g to protect the oamhost1.mycompany.com:7777/index.html and two oam servers are on, I'm redirected correctly to authenticate on oamhost1 and it works perfectly. When I take the oamserver1, the redirect fails, I get an error page, and it redirects me to (stop now) oamhost1. But when I manually replace oamhost1.mycompany.com by oamhost2.mycompany.com in the address bar, authentication works properly.
  
  So the problem I have is not as long as the system will not work, but rather that there is no failover of the URL redirection. That is to say the webgate will always redirect to oamhost1 for authentication even when turned off, even when a redirect to oamhost2 for authentication works.
  
  Anyone where I can fix this minor but annoying?

  You will need to install a load balancer (using SST or any Web server or a load balancer), and balance the load 2 servers OAM on 14100. Example: MatchExpression /oam * WebLogicCluster = node1.oam.com:14100, node2.oam.com:14100

  After that you will need to change the value of "OAM host server" through "Configuration system-> common settings" and change the value to the URL of your server that does the load balancing.

  Once the above changes, when you hit your protected site, you will be redirected to the url of the load balancer for oam who, in the case of a failure in node OAM are failed over to the other node.

• Network of twinning with Port trunks to support the host ESX VShere 4 with several NIC for load balancing across a HP ProCurve 2810 - 24 G

  We are trying to increase production of our ESX host.

  ESX4 with 6 NIC connected to HP Procurve 2810 - 24G 2 ports; 4; 6; 8; 10 and 12.

  The

  grouping of parameters on ESX is rather easy to activate, however, we do not know

  How to configure the HP switch to support above connections.

  Pourrait

  someone please help with a few examples on how to seup the HP switch.

  Help will be greatly appreciated as we continue to lose tru RDP sessions

  disconnects.

  Best regards, Hendrik

  Disabling protocols spanning-tree on the Procurve ports connected to the ESX host is going to promote a recovery more rapid port. Similarly, running global spanning tree is not recommended if you mix some VLAN iSCSI and data in the same fabric (i.. e. you do not want a STP process to hang storage IO). Spanning tree on your switches, look PVST (or Procurve BPMH) to isolate the STP VLANs unique events.

  In regard to the load balancing is, by default (route based port ID) value algorithm requires less overhead on the ESX hosts.  You may not use LACP on the Provurve the lack of facilities LACP ESX. You must use "route based on the IP hash" sideways ESX and 'static trunks' on the side of Procurve. Unless you have specific reasons why your network need loads this configuration, I'd caution against it for the following reasons:

  (1) IP hash requires thorough inspection of packages by the ESX host, increasing CPU load as load package increases;

  (2) the static configuration puts switch physics rigid and critical ESX host port mapping. Similarly, groups of ports all will fail as the Procurve batteries for management only and won't be on switches 802.3ad circuits Group (i.e. all ports of a group of circuits must be linked to a single switch) - this isn't a limitation of the port ID routing;

  (3) K.I.S.S. love port ID mix of port ID, beacon probe and failover on the port assignments you will get segregation of the raw traffic without sacrificing redundancy - even through switches.

  I hope this helps!

• Http-plugin supports metric base load balancing? like Mod_OC4J!

  He supports balancing the metric-based in Oracle 10 g AS OC4J.
  
  It's a good way to spread the query load among OC4Js based on a metric which was reported by OC4Js.
  
  When load balancing based on the metric system is enabled, requests are routed between based OC4Js on the report of a defined metric, as the ratio of round robin, automatic relaxing... etc.
  
  
  WebLogic server HTTP-Plugin has similar features? Could experts suggest simiilar workaround (s) or solution (s) Please?

  I think you should connect with Oracle Sales. Let them to clarify.

  It is a good idea.

  Since now, WLS have no metric based load balancing.
  For load balancing, you must configure the proxy servers.

  http://e-docs.BEA.com/WLS/docs103/cluster/setup.html
  http://e-docs.BEA.com/WLS/docs103/cluster/load_balancing.html

  Give them some pressure to release new features.

  My concern, metric according to load balancing is explicitly vital for most of the users using OC4J. Y at - it no alternative to measure loading WLS? As I can build module
  or plugin Web levels... of course raise this request to my sys development team exactly.

  WLS do support 3 types:-Round Robin load balancing, load balancing based on the weight & Random load balancing.
  In the near future, I guess they do not provide as metric base load balancing MOD_OC4J.

  If you like to take some tasks to measure, I sugget contact you your sales local oracle for assistance. They have probably you persuade enjoying service professinal anyway.

• Load Balancing does not not on 2911

  Hello people,

  I have some difficulty to operate the Load Balance on my 2911.

  I have followed the editing on this site:

  http://www.Cisco.com/en/us/Tech/tk648/tk361/technologies_configuration_example09186a0080950834.shtml

  and APARENTLY it works, but not in reality, because I see packets using a NAT IPS bot thru, but when I check on the interfaces I see we're not receive / send anything.

  Background:

  G0/0, I have one ISP, other 1/G0, G0/2 my network.

  Hello

  Yes here you only have a single default route installed (one from the DHCP server) so it can't NAT on the other interface as it can route on this one.

  Change your configuration like this:

  no ip route 0.0.0.0 0.0.0.0 track GigabitEthernet0/0 123

  no ip route 0.0.0.0 0.0.0.0 200.122.102.1 254

  IP route 0.0.0.0 0.0.0.0 dhcp

  IP route 0.0.0.0 0.0.0.0 200.122.102.1 254

  Now if you want to follow the first route look at this document:

• Active ADF data service does not work when the load balancer compresses

  Hello
  
  I have Active Data service table in a page.
  After you enable the setting cache and turned on compression on the hardware load balancer, Active data service table refresh no more in the application.
  
  We use F5 for balancing load and data compression.
  
  Pointers?

  You can check if your F5 loadbalancer has enabled text compression.
  Disable compression of text.

• What load balancing algorithm using the LRT224?

  I was wondering if anyone knew what algorithm of load balancing the LRT224 use since I can't find it anywhere and the telephone support line does not.  It is very similar to the RV320 of Cisco that uses Weighted Round Robin, but I don't think that the Linksys uses this algorithm because it includes speeds of bandwidth unlike the cisco that does not work.  and if anyone can also check that this unit doesn't package base rather than load balanced session load balancing.  as much information as possible would be appreciated!

  The standard of the LRT load balancing is alternated:

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN1

  4 TCP connection to website1.com-online WAN2

  If you enable the feature (recommended) sticky load balancing load balancing is done on a base per session instead of the base of the connection.

  Example:

  1 TCP connection to website-online WAN1

  2 TCP connection to website2.com-online WAN2

  3 TCP connection to website2.com-online WAN2

  4 TCP connection to website1.com-online WAN1

• Hi ALL, did any attempt on the virtual computer NETWORK load balancing using HYPERV on UCS blades

  I try to configure the CASE server cluster by using the Unicast NLB on the virtual machine on different blades on the UCS, it works for awhile, then he abandoned packages.

  I heard that this screenplay of unicast is not supported in the UCS when she used END-host mode in the fabric interconnet...? any attempted before.

  Would it, I use the multicast mode is that something needs to be done on the FBI62020 or the LAN switch upstream. ??

  Header note I found on the implementation of UCS for mulitcast NLBL:

  Microsoft NLB can be deployed in 3 modes:

  Unicast

  Multicast

  IGMP multicast

  For series B UCS deployments, we have seen that the multicast and IGMP multicast work.

  IGMP multicast mode seems to be the more reliable deployment mode.

  To do this, the monitoring settings:

  All NLB Microsoft value "Multicast IGMP" nodes.  Important!  Check ths by logging into EACH node independently.  Do not rely on the MMC of NLB snap.

  An IGMP applicant must be present on the VLAN of NLB.  If PIM is enabled on the VIRTUAL LAN that is your interrogator.  UCS cannot function as applicant IGMP.  If an interrogator of functioning is not present, NLB IGMP mode will not work.

  You must have a static ARP entry on cheating it upstream pointing IP address Unicast NLB on the multicast MAC address NETWORK load balancing.  This need will set up, of course, on the VLAN of the NLB VIP. The key is that the routing for the NLB VLAN interface must use this ARP entry as a unicast IP ARP response may not contain a multicast mac address. (Violation of the RFC 1812)  Hosts on the NLB VLAN must also use the static entry.  You may have several entries ARP.  IOS can use a function of 'alias' of ARP. (Google it.)

  How Microsoft NLB works. -The truncated for brevity Mac addresses.

  TOPOLOGY OF NLB MS

  NETWORK VLAN 10 = subnet 10.1.1.0/24 IP load balancing

  VIP = 10.1.1.10 NETWORK LOAD BALANCING

  Arp entry static switch advanced IP 10.1.1.10 upstream to MAC 01

  NLB VIP (MAC 01, IP 10.1.1.10)

  NODE-A (AA, MAC IP:10.1.1.88)

  NŒUD-B (MAC BB, IP:10.1.1.99)

  Using the IGMP snooping and interrogator VLAN snooping table is filled with the mac NLB address and groups pointing to the appropriate L2 ports.

  MS NLB nodes will send the responses of IGMP queries.

  This snooping table could take 30 to 60 seconds to complete.

  Host on VLAN 200 (10.200.1.35) sends traffic to NETWORK VIP (10.1.1.10) load balancing

  It goes of course to VLAN 10 interface that uses the static ARP entry to resolve to address MAC 01 VIP NETWORK load balancing.

  Since it is a multicast frame destination it will be forward by the IGMP snooping table.

  The framework will arrive at ALL NLB nodes. (NŒUD-A & NŒUD-B)

  NLB nodes will use its load balancing algorithm to determine which node will manage the TCP session.

  Only one NLB node will respond to this host with TCP ACK to start the session.

  NOTES

  This works in a VMware with N1k, standard vSwtich and vDS environment. Where surveillance IGMP is not enabled, the framing for VIP MAC NETWORK load balancing will be flooded.

  NLB can only work with TCP-based services.

  As stated previously mapping an IP unicast to a multicast mac address is a violation implied by RFC 1812.

  TROUBLESHOOTING

  Make sure your interrogator is working. Just to clarify that this does not mean that it is actually at work.

  Wireshark lets check that IGMP queries are received by the NLB nodes.

  Make sure that the ARP response works as expected.  Once Wireshark again is your friend.

  Look at the paintings IGMP snooping. Validate the L2 ports appearing as expected.

  Solution: Change the NLB mode of operation of "Multicast" to "multicast IGMP', which modifies balancing load NETWORK VIP MAC at 0100.5exx.xxx Beach, allows to transfer occur as expected.

  Q: and if I switch to switch mode, which means all of the profile and the settings on the servers are completely exhausted and I need to recreate them. ???

  -There is no impact on the configuration, you have done service profiles.  they will continue to work as expected.  Mode selector has the FI behave more like a conventional switch.  Most notable is that Spanning tree will be activated and if you have several uplinks yew, tree covering weight will begin to block redundant paths.

  You need to review your topology and what impact tree covering weight.  Generally, we at the switch port upstream defined as "edge master", you want to delete this line.

• Network [vSphere 4.1] load balancing and failover vMotion

  GoodMorning everyone.

  I have some doubts about the configuration of the network for vMotion in vSphere 4.1

  I know that I can activate a single portgroup VMkernel for vMotion on the single host, but can I have this portgroup in a vSwitch with two or more physical NIC attached.

  Currently, I managed to have a vSwtich with vMotion and management of trade wth two NICs (see attachment).

  Both NICs works very well with the recovery for both exchanges.

  I would switch to a vSwitch with multiple network cards and I have some doubts.

  It seems that I could configure it... but the load balancer for vMotion supported on vSphere 4.1?

  And also, have the protgroup of vMotion in a switch with several network cards, is there a way to check what physical nic is currently used by vMotion?

  I am currently under a license from the company.

  Thank you all for your help.

  vMotion for vSphere pre 5 does not support Multi-NIC, in vSphere 5, you can configure several VMKernel enable vMotion and select different Nic Active and load balance between the two vmnic, but unfortunately not in vSphere 4.x

  For the management of ESXi, if you set active on both network adapters, you not to cross any active advantage / standby because it will only use on vmNIC, unless there is still a failure... but 1 vmNIC just because bandwidth is usually not a problem for the ESXi management only.

  So the answer: upgrade to vSphere 5 for multi-nic vMotion and don't worry ESXi management as an active NETWORK card is more than enough bandwidth,.

  Here's a YouTube on the Multi-NIC vMotion http://www.youtube.com/watch?v=7njBRF2N0Z8 configuration

• IP hash load balancing

  Hello

  I tried to set up IP hash load balancing across our server of vmware.

  I configured added 4 nic to a switch virtual and added the ip routing of hash for all groups of port on the vSwitch.

  (it is noted that one of the port was the management vmkernel port group)

  I then found the physical ports on the switch that the nic 4 plug and adds in a port channel.

  I used the following commands to create the Group of channels

  config

  interface port-channel (number)

  to add ports in the channel of the port:

  config interface ethernet (port number)

  channel-group 1

  I did it for all 4 ports to which the 4 server nic was connected.

  Once I had done this connectivity network completely abandoned. Workstations were more able to talk to the whole server vm (domain controller, Server database etc.)

  I took the ports except the port channel group - and the restored network connectivity.

  Can someone tell what I'm doing wrong here?

  VMware does not support LACP, you must set up the Group of channels in 'market '. Please check your configuration of the KB below phyiscal switch port:

• Performance / load balancing

  Hello

  I am currently trying to load balance my guests / VM. I have 4 DELL R610 with 48GB of RAM. I then 20 VM. I have the license "Advanced" without DRS.

  What would be the best way to ensure that I use my hosts to their full potential? and second, what is a good rule of how many resources you use on a host? 70% + 70% RAM CPU?

  Thanks for all your help constant. I really appreciate it.

  -allthebest1976

  I don't think that there is really no "rules" as to what your environment should be to in terms of memory and CPU usage.  It varies a lot depending on each environment and workloads that you are running.  Instead of getting hung up on a set of numbers for the CPU and memory, I would do just that your environment is designed for the following:

  (1) can high availability - withstand the loss of one (or more) host without overloading the remaining hosts?  You really need determine what that your SLA is in terms of guests how much you can afford to lose, and if you need all the virtual machines to run in the event of a loss of the host.  Ensuring that you have enough available resources to support the loss of a host is a very important point and can easily get overlooked because it is so easy to continue to deploy new virtual machines.  Striving to get the CPU and memory, using the order of 60-70% may limit your ability to lose hosts without serious performance degradation.

  (2) growth - you have the ability to increase your environment with the needs of your business change?  You can add new virtual machines if there is a merger of the company, a new application in the House, or if you need to increase their testing, etc.?  Growth is often overlooked but planning so that it advances can save money down the road.

  (3) performance - how guests are performing in your environment, and how do you make them?  As you start to add more virtual machines and use resources increases, you can start to experience performance problems in the guests.  Same question as above - it is so easy to deploy new virtual machines that you can quickly get to the point where you have too many virtual machines per host and no easy way to balance the load with vMotion.  If you still meet the needs of application performance, and the two points above have been satisfied according to the requirements of your organization, then you're doing something good!

  I know that looking for probably a response that resembles something more like "all hosts should be 50% CPU and 60% usage of memory" but it is not really an easy way to give that answer.  I'm trying to make sure the 3 criteria above are met and worry less what the real numbers are like.

• NETWORK load balancing issues

  Hi all

  It is a strange and I can't really find anything when searching. I just wanted to know if other people have seen this? and if there is a work around?

  OK, the virtual environment that I administer is quiet large and the love windows NLB developers where I prefer f5 or hardware NLB. So it is quiet assign windows NETWORK load balancing clusters in the virtual environment, the issue I encountered is if the critical path for an application passes a cluster nlb to another (so they talk to each other). If a node of each of these clusters is on the same physical host NLB rocking.

  Why?

  well windows NLB when a request is sent to the VIP address all nodes in the cluster must meet before it is executed by one of the nodes, tests that I've found is that if a node of each group is on the same host demand seams to stay internal to the ESX host, as it goes, I know where that IP address is and goes to a single node until that node is waiting for the other nodes of the cluster in order to recognize the request but they never get it the whole thing stopped and happens to expire and the performed by the team of network packet capture won't let even the host he sews.

  OK, a few rules affinity could solve this but I'm talking about 8 knots, talking to a node 4 cluster which then in turn talk to another cluster of 4 knots and im talking about another 50 like that until the point where DRS. can not move whatever it is as well that the rules are a nightmare administrave especially since only 2 machines can be in a rule.

  All hosts running ESX 4 Update 1 and running on HP blades, unfortunately we run on unicast mode, due to the size of the environment networks don't want to or can't add all switches/routers arp entries. It is configured as recommended by using unicast.

  I can reproduce this problem every time still in test. would it be because of the unicast? I don't see how.

  I would add also that it should not be 2 nlb cluster, if a server client attempts to hit the VIP of a windows NETWORK load balancing cluster and it is on the same host as one of the nodes it will expire as a single node gets applications. F5 NLB works perfectly, and when they are on hosts separate windows THAT NLB works very well also.

  Just came across this because the jobs would come about the application does not, by trying to hit the vip on the correct port for the requesting server, it wouldn't connect and the support guys would vmotion a knot and it would usually fix the issue, and if it does not pass all the nodes on the same esx host and it would work every time (I know (, but until the full time vmware resources came on board as me not doubtful we had the time to really watch)

  any ideas or comments would be great hope I have explianed the question clearly enough

  See you soon

  See: http://www.vmware.com/files/pdf/implmenting_ms_network_load_balancing.pdf

  You must use the multicast.
