• 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

• Load balancing across the NETWORK interface card

  Hello

  Our ESX Server's NIC six, two for SAN, one to the dedicated Service Console and three for the virtual computer LAN traffic. I noticed one thing look in the performance tab in VC, is that all LAN traffic seems to go on one of the three the NIC and the other two are practically inactive.

  If I look at the network configuration for the vSwitch those with three cards network, grouping of NETWORK cards is set for 'road based on the original virtual port code '.

  Can anyone advise how to get a more 'democratic' usage of the three NETWORK adapter?

  
  
  As seen on http://www.eqlforums.com !

  How many virtual machines you host? With the load balancing algorithm you have selected (default), traffic is balanced to the vNIC level (i.e. all traffic from a given vNIC always through the same bear). This is the case for all, but the IP hash algorithm, which requires you to 802.3ad static port aggregation on your pSwitch. In most cases, there is no need to worry about the use of bear - if it's a GbE NETWORK card, you're probably not close to push the limits.

• 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.

  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.

• VPN 3030 load balancing

  Hi all

  Asked me to configure the load balancing between two hub Cisco VPN (Cisco VPN 3030).

  I set up two such boxes mentioned in the cisco Web site

  [url] https://www.Cisco.com/en/us/products/HW/vpndevc/ps2284/products_tech_note09186a0080094b4a.shtml [url]

  After you enable VPN load balancing, I get the error described for 30 seconds.

  Quote:

  One of my friends said me that try with encryption active but not different.

  I searched in google but did not get any solution. I am now hlepless. If any of you guys have met this kind of problem before could you please help to solve this problem...

  Thank you

  Please set each device to have different priorities and then charge two devices.

  If this does not work then you can confirm your settings of the VCA have been properly configured and applied to the public interface? The following links provide more details on how to configure filters VCA:

• Where to configure clustering: on the web server or a load balancer?

  Hi all

  a few installation questions. I read on clusters and where to set up the pool. My main goal is to reach stickness session, session failover. but I'll ask them later when I clarify below.

  If my installation is

  -> Cluster WebLogic Web server, I need to install the cluster weblogic web server plugin.

  If my installation is

  Balancer load-> cluster WebLogic, I need to configure the LB, cos the LB must meet certain criteria.

  My planned Setup is

  Webserver-> LB-> cluster WebLogic. the weblogic balancing is done at LB. I'll have to set up the LB to balance to the cluster.

  I think I'm NOT configure the weblogic on the correct Web server plugin?

  Configuring the web server is obviously a proxy directly through the lb.

  So my next qn: the configuration to the LB is to balance the weblogic cluster OR a list of all the backend .jsf page server? Assuming that my application launch page is a jsf page. Enjoy your advisor.

  (a) you have little sticky on LB. On the Web server, Weblogic Plugin will take care of permanent sessions.

  (b) Yes, you need to add to your weblogic.xml in the application. There will be no conflict. However, your heap memory usage will increase as you could store session information on two servers.

  "Circumstances and considerations should I need a LoadBalancer in front of my weblogic cluster? --

  The main reason you would use a load balancer is to keep the VIP for your application. He would charge the balance between the weservers. Also usually SSL is stopped at the level of load balancer. It helps you reach cross clutser replication etc... You can read this document... Failover and replication in a Cluster

• Hyperic HA does support load balancing?

  Hello
  
  We try to implement architecture Hyperic high availability based on JBoss HA and distributed cache EHCache. Our version is 3.2.3 EE.
  The cluster configuration is quite simple with the HQ High Availability Guide.
  Thanks for this guide and the esayness of the configuration of the feature!
  
  My first question was, the agent, what server IP should I use? I put with node 1 and other agents with node 2
  = > the synchronization between nodes works very well.
  
  Therefore, I have some additional questions.
  
  1 / can I have a single point of entry for agents with some load balancing and failover capability?
  For example, if an agent is sending information with the Node1 and this node breaks down or the server is restarted for maintenance purposes, the agent information will be lost.
  
  2 / same question for the application, can I have a single point of entry URL with some load balancing and failover capability?
  
  Thanks for your help.
  
  Nicolas.

  HQ Enterprise HA for failover, but do not support for load balancing.  You will need before your HQ multiple servers with a load (software/hardware) balancer which will relay agent to a live server.  The load balancer must be staged all agents in a single node of 'master '.  If this server is unavailable, another server will automatically become the master node and agents should be redirected to this node.

• NIC Teaming: ID v-port-based load balancing

  Hey all,.

  According to VMWare ESXi does not support physical host interfaces LACP trunks.  I was told that the NIC teaming feature will allow you to specify which physical interface traffic is pushed through the source IP/VM database.  I was able to locate the NIC teaming settings in load balancing vSwitch properties, but I cannot determine how to set up a specific virtual machine, vNIC or source/destination IP address to use a specific physical NIC

  Can someone tell me how to proceed?  The setting of balancing says "Route based on originating virtual port ID"...  This isn't not always tell me how to assign a virtual interface to a specific physical interface.  Ideally, I would like to specify a destination IP address and a physical interface to use when accessing this IP address.  Simply being able to map a group of virtual machines to use a physical interface (without going through the VM groups on different vSwitches) would do well.

  Any suggestion is appreciated.

  Thank you!

  Intellectual property of hash based mode, 1Gbit/s physics 2 network cards can be effectively combined in 1 2 Gbps link?  Meaning regardless of VM, source/destinaltion IP/network, traffic etc will be shared between the two network cards until they are both is completely saturated?

  No, certainly not. It's like Weinstein explained. The NETWORK card used is based on the source and destination IP.

  You can take a look at VMware Virtual Networking Concepts that explains the different modes in detail.

  Route based on the hash of the IP ... Regularity of the distribution of traffic depends on the number of TCP/IP sessions for unique destinations. There is no advantage for the bulk transfer between a single pair of hosts.

  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!

• Difference between the Port ID of the load balancer and MAC?

  There are three strategies for load balancing in 4.0 (one more now in 4.1):

  Function hash IP route

  Route based on the originating Virtual Port ID

  Route in function interference source to the MAC

  I think that I understand perfectly the "IP hash" and how it relates to switches, but what really is the difference between 'source MAC' and 'Port ID'?

  They seems both to do something very similar, which is attached a VM to a physical network card. Why someone should choose the CBC MAC and why the Port-ID? Is there a difference in the way that traffic will extend that could be interesting, when you do a design?

  Hello.

  To simplify, to really all boils down to the formula used to distribute traffic natachasery.

• Double connection ISP and load balancing

  Hi all

  I have the Cisco 2911 router k 9/s with 3 GB ports. I have also two different ISP connections, all have two different available bandwidth (one is asymmetrical, else a symmetrical).

  What I want to achieve is to ensure the balance of Nice load between two ISPS for all PCs behind the NAT device.

  What I know so far, it's that I can use CEF or PfR/REL. For both of this technology, I have some doubts.

  CEF: distributes the network load between the two connections based on sessions (which is good, because I strongly to use tools like Skype or Lync for audio/video conversations). However, what is happening, when I get on one of the ISP connections broadband bandwidth max? He's going to choke for 50% of the connections? Or it will detect the use of bandwidth and to force using second ISP?

  PfR/REL: as far as I understood it resolves my concern regarding the use of the connection, but what happens to the session? Should it also be based on this mechanism? As you know that it is very important for audio/video connections.

  Are there other tools that can provide these load balancing? I know DAB, but I don't want to decide manually, where each service (e.g. http or ssh) will have to go. I'm looking for something more automated.

  Thanks in advance for any help.

  Hello

  I assume that you have a static route for the subnet 213.192.65.0/24 on top of the output and with the combination of order

  network default IP 213.192.65.105 213.192.65.105 IP address is installed as a default gateway. What is the #2 ISP?

  If so, it explains why he always goes on ISP2 only.

  http://www.Cisco.com/en/us/Tech/tk365/technologies_tech_note09186a0080094374.shtml#flagging

  Just remove the config:

  Noneip default-network 213.192.65.105

  Noneip default-gateway 213.192.65.105

  Then again check the routing table:

  SH ip route

  Hope it helps.

• DSwitch load balancing

  I have DSwitch 5.5 in vsphere 6.0

  Two 5.5 esxi hosts to connect to these virtual switch of two network cards.

  NICs works in IP HASH (the real switch side cisco 3570 I did port channel). Everything works fine, but I have question.

  Can I do a load balancing for a single host examle: IP hash, on the other - on the virtual port original? If say, how? I can see only one setting for all VDswitch

  

  

  Can I do a load balancing for a single host examle: IP hash, on the other - on the virtual port original? If say, how? I can see only one setting for all VDswitch

  As you can see on your screenshots, settings are for port group and not overall overall dvSwitch. You can have different settings for each physical ESXi host though, all guests must use the same algorithm as specified by the port or load balancing groups. If you want different settings by physical ESXi hist, then you will need to use the local standard and undistributed vSwitches, but we can ask the question of whether such a potentially unpredictable and inconsistent configuration is desirable.

  On a side note, you can set up several groups of ports with different parameters on a vSwitch (d). However, mixture etherchannel/LAG/LACP IP - hash based load balancing with any other balancing as virtual port ID in the same uplink / vSwitch (d) is not supported.

  In addition, it is not sensible, your acts only physical switch as a single channel for all traffic and will not be able to differentiate as several ports on an ESXi host groups could do.

• Windows 2008 network load balancing

  I hope someone can help.

  I'm looking to start to test the Windows 2008 network load balancing. This will serve a webfarm. I went through various whitepapers, and forum messages but who have a few more questions:

  1. I get VMWare recommends multicast. Windows 2008 gives you two options, multicast and IGMP multicast. Seeing that I'm not an expert in network management, I'm a little nervous about the switched. Apparently to enable IGMP Snooping on your Cisco switches eliminate this? Is this true, if so you need install your cluster as IGMP Mulicast?

  2 do you need to have dedicated NICs for the NLB cluster, separate vSwitch etc.? If this is not the case, there will be interference with the existing production network?

  3 is a necessary static arp entry on your switch? All switches or just the farm goes where the ESX hosts are connected to?

  Some info would be appreciated.

  1 have not tested, but IGMP snooping is what caused problems before because the switch ports would not join the group correctly, so it is suitable to test whether the OS is ready to send packets.

  2. it is better to use separate vNIC to the virtual IP address of the NLB cluster

  3 static arp would be necessary if the IGMP snooping does not work for the switch ports that will be the virtual machine hosts that are part of the NLB cluster.
