In transparent mode load balancer

• 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.

• How do RV082 access secure web sites load balanced mode

  I just bought a gateway/router RV082 Dual WAN because I have both cable and DSL feeds in my office. Everything works fine until I try to access a secure web site or have a conversation through my Vonage internet phone. In failover mode all works. As soon as I select Load Balancing, I have outages. I do not see this listed anywhere as a 'problem' so there must be some kind of workaround if this isn't a bug. Has anyone else seen this and how did you resolve teas?

  Thank you

  Poul

  ^.. ^

  The problem you are having is your doing load balancing and traffic to the secure Web site is to get out the two wan.  The secure site is waiting for a response from the original wan ip, which has established the connection, and then it receives the response from the other wan ip address.  It is a common problem.  You can do protocol binding tab management system and have everything that your https traffic out a single IP wan, this will fix this issue.

• A load balancer armed mode

  We install a load balancer of arm to load web servers scale 2 and it will be attached to the web logical switch.

  in arm mode single vnic is used to receive and send the traffic.

  My question is this type of vnic will be configured as internal or uplink.

  For a LB armed, it is recommended that actually use an interface type of uplink for the on-board service gateway.

  If after the initial deployment, you want to change the configuration of the default gateway, this is supported only if the default gateway is on the same network as the interface of uplink.

• Load balancing mode

  NSX LB operate in one of the 2 Modes: an arm and Inline Mode.

  But in NSX ICM course lab workbook is another mentioned mode: 2 in armed mode. Also in this transparent mode check box is not selected.

  What is this mode of arm 2.

  NSX Edge has no concept of 2 arms or deployment 1 arm.

  The NSX know Edge is in the pool:

  . Transparent enabled-online SNAT is configured

  . Transparencies with disabilities-online SNAT is not configured

  For example, when you deploy an edge in arm mode 2:

  "Customer - edge - servers_load_balanced" (with servers by default gw = border)

  If you have active Transparent, it will works and the server will see the real client IP address @, so that the server will respond to Client IP @ (via the default gw = border)

  If you have disabled transparent, it works and the server will see the IP edge @, so that the server will respond to the IP edge @ (which will be NAT to answer the customer)

• 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.

• 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

• 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.

• ACS 5.3 - GANYMEDE + NAS IP address load balancing

  Hi all

  I am currently evaluate a scenario where application AAA are load balanced on several instances of GBA 5.3. Application delivery controller is running in mode of L3, which naturally causes address of the original packet source IP be replaced by a random proxy address.

  As far as RADIUS is concerned, I can fully determine the introductory NAS for instance using a "Device Filter" condition. ACS seems, unfortunately, do not have the opportunity to do the same thing for GANYMEDE. According to the manual, only the real IP from the received packet is taken into account. Also I came across the "NAS-address" attribute in the dictionary of Protocol, but it cannot be used in a custom either condition.

  Someone happens to know how recover a GANYMEDE request initial IP address + in order to use it for other police services?

  See you soon,.

• TMS 14.5 and redundancy with F5 load balancing

  Hello

  I'm looking in the installation guide for TMS 14.5 to design redundancy TMS with the F5 for one of my clients. I wonder if there is any requirement of specific network for the TMS1, TMS2 and F5 must be in the same VLAN or not. My client have a TMS with TMSPE and deploy the TMS Server 2nd in different data center and will use existing F5 load balancing. They cannot have the same VLAN as a current TMS server in the new data where 2nd MSDS server will be Center. Existing F5 load balancing is also, in the VLAN different already.

  y at - there no specific review we need to take care of the redundancy?

  Thank you

  Chris

  As the TMS 14.4, TMS no longer an active/active load-balanced mode and now works as active/passive.

  You can find the details in the "Configure a redundant deployment" section of the Installation of TMS and Upgrade Guide (latest version 14.6 related).

  As long as both devices are accessible (and your F5 can route traffic to each of them according to the needs), it does not matter what VLAN, subnet or a location that each MSDS server resides on.  Information of VLAN in the guide are just one example of how it can be configured in a simple load balancing scenario.

• vRA 7 load balancing with embedded active / standby vRO

  I have a vRA environment 7 with vRA HA devices that have integrated the vRO. I want vRO to an Active/Passive configuration, but when I do the load balancer declares the node with the vRO vRA Eve out of service.

  It seems that between 6.2 and 7 that VMware has changed the vRA health check to watch/vcac/service/api/health instead of/vcac/services/api/status. This new target now fail because it shows a service as in offline mode. While it is fairly clean and is probably better than the old health check, it kills the idea of an active configuration / standby vRO.

  Any ideas on how I can get around this? Thank you!!

  The problem that you are facing is that devices of internal load balancing is managed by HAProxy. I don't have * think * that it promotes health checks, this is why active/active approach for vRO. I suspect that if you want to use Active/passive, you will need to switch to external devices.

• Network Load Balancing

  Hello

  I have some difficulty of implementation, network load balancing in VMware - I'm not sure what mode of load balancing that I use.

  I have an ESXi 5.5 - host connected to a HP Procurve switch I have configured for 2 VLANS (40,41).

  On the switch, I created 2 trunks (Trk10, Trk20) I scored on two VLANs:

  trunk Trk10 trunk 23,47

  24,48 trunk Trk20 trunk

  VLAN 40

  name of "trial".

  untagged 1-22

  Tagged 50, Trk10, Trk20

  no ip address

  output

  VLAN 41

  name "PLC".

  tagless 25-46

  Tagged Trk10, Trk20

  no ip address

  output

  Port 23 and 47 will ESXi-host1 and port 24.48 will ESXi-host2.

  40 of VLAN is to have the network 192.168.40.0/24.

  41 of VLAN is to have the network 192.168.41.0/24.

  I created a virtual switch that has 2 NICs in it, but how do I set the load balancing mode?

  The virtual machine is slow on the internet right now, and I suspect the packets going to the VLAN evil.

  (Time of balancing mode is set to 'Route based on the original virtual port code').

  Kind regards

  Soren

  Let me know if you need more information.

  Could you do a 'show interface memory' and 'show interface' on the HP switch and paste it here?

  I would remove the trunks as I don't see why this is necessary in your configuration...

  Make sure the road based on virtual port ID what origin is selected on vSwitch1 and both exchanges configured (PLC and trial).

  Remove the trunks on the HP switch and tag/UNTAG required VLANS on individual ports that were previously used in these trunks...

  Quick config necessary for HP...

• Network load balancing ibm hs22 esxi 5

  Hello everyone, I have a HS22 blade connected to a bladecenter H with ethernet 2 e/s switching modules. So my HS22 has 2 nic and each blade is connected to the switch diferent on the center of the blade. I want to configure nic teaming on me HS22 Server ESXi 5. the load balancing mode I configured the default option on the ESXi. I would like to ask if I need to connect two ethernet io modules switching to a single external switch, or it's better to connect them to 2 diferent switches and maybe configure the VLAN same on ports of all swithces?

  It depends on the level of redundancy you want for your network. There should be no problem with 2 switches if they are properly configured.
