• How do I see the IP Source address of a customer using ACE One-armed-mode of loading balance HTTP proxy request

  I use a device of 4710 Ace deployed in armed mode, use Source TAR to balancing HTTP request to a couple of Proxy servers.

  Everything works well, but the thing is that I do not see the client IP addresses on the Proxy logs, so I can't keep track of them.

• 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.

  "Discover Ken Cline" [the great vSwitch debate - part 3 | http://kensvirtualreality.wordpress.com/2009/04/05/The-Great-vswitch-Debate%E2%80%93part-3/] "for many more details on each option works.

  Good luck!

• 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.

• 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!

• SRW2008 load balancing

  Hi, what is the best way to balance the two connectrions with SRW2008 internet? Is possible to also "switch"?

  Thank you in advace

  Nino

  Aggregation of links (sometimes called "Bundling") combines two or more physical ports into a single logical port. After that, you have only one logical port. This allows you to increase the bandwidth on a link. To use it, you must connect the ports combined in another switch/device that supports the same and has the same configuration.

  So, Yes to use the aggregation of links, you'll need another switch like the SRW2008.

  However, the aggregation of links isn't load balancing. The logical port is still a single connection, even if it's running on multiple threads. It must connect to the same physical device.

• How to configure das MD3200i load balancing

  I would like to connect a MD3200i (with two raid controllers) to one of our Windows 2003 R2 servers without the aid of a switch.

  After most of the documentation, some things remain pretty obscure to me. I'm new to MPIO/balancing and cannot figure how to set up.

  Is it possible to connect 1 nic host to RAID 0 and another host nic to RAID 1 and then combine the bandwidth? Thus having 2Gbs instead of 1Gbs? Or is it only a redundant path sollution, happening the other controller in case of failure of the first line. How can I configure this regarding the IP addresses, subnets. And where is the configuered to load balancing. This is explained in the documentation? I can't find it. I found a few examples that include the use of a switch, but none with das sollutions.

  What I have is 4 the MD3200i UTP cables to connect to the host. 2 the high raid controller and 2 on the lower raid controller. And use that I have 4x1Gbs, resulting a connection 4Gbs to a single partition on the MD3200i of load balancing.

  Thanks for any help.

  Multiple paths and in windows 2003 load balancing is managed by the driver MPIO is installed when you install the 'host' or 'full' version install MD Storage Manager. There is no need to separately aggregated network adapters to get the aggregate bandwidth. The pilot, by default, uses repetition alternated on all ports connected to a single controller.

  Also, for a single virtual disk, all i/o through a single controller and the second controller acts as a redundant path. So, if you have 2 x 1 Gbps connections to each controller, you will have, at most, 2 Gbps for each partition. Now, each controller can have virtual disks, so the second controller may have a second partition that will also have a separate between 2 x 1 Gbps connection.

  You can set IP addresses and subnets that are similar to the way that you would with a switch as long as you can test the connection port. It would be wise for each NETWORK card on the host on a different subnet and each port on the MD3200i on the corresponding subnet. This will make it easier when you set up your iSCSI.

  You can use the configuration utility to MD in place your iSCSI sessions too

• 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.

  CSCtx27555 [Bug-preview for CSCtx27555] Unknown multicast with destination outside the range MAC 01:xx: are deleted. (6200 FI fixed in 2.0.2m)

  http://Tools.Cisco.com/support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtx27555

  fixed in 2.0(2m)

  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.

  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:

• 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

• 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.

  Best regards

• Client based in 12 G load balancing

  We have a JDBC configuration against an address scan with client load balancing enabled.

  Example:

  JDBC:Oracle:Thin:@(Description=(LOAD_BALANCE=on)(Address=(Protocol=TCP)(Host=xxxxxxxxxxxx.de)(port=xxxx))(CONNECT_DATA=(service_name=XXXXXX)))

  What I understand of Diference between Client-side and Server Load Balancing If you do not use the server load balancing, you can bypass by connecting the service that identifies a particular node of RAC name.

  
  

  My question is, if you have a connection pool object this configuration and if the name service maps node to goes down, what happens to the connection connection pool?

  
  

  Issue 1) Don't scan address switches to the available according to the name of the service node, then the JDBC driver on the client must file all embusked connections and reconnect the available node? or is all the agnostic client failure of node on and all the old connections available in the pool are available for use?

  
  

  
  

  The client side or server balancing side basically works for the same purpose. The difference is that you do not have all the customers to reconfigure then change something in the environment, such as adding or removing a node such as the side server.

  Answer your question...

  If you mean the shared server architecture by connection pool, the shared server session connected to node 1 will die and everyone shares this session should log. Failover is not automatic, you must specify the failover clause in the JDBC or TNS connect string:

  TEST_TAF =

  (DESCRIPTION =

  (ADDRESS = (PROTOCOL = TCP)

  (HOST = rac - scan.example.com) (PORT = 1525))

  (CONNECT_DATA =

  (SERVICE_NAME = test)

  (FAILOVER_MODE = (TYPE = SESSION) (METHOD = Basic))

  ) )

  Or if you use failover and load balancing services you set failover described below:

  for 12 c: srvctl $ add orcl db-test - oel6vm1 favorite-available oel6vm2 - tafpolicy BASE - failovermethod SESSION service service - failoverretry 5 - failoverdelay 60

  for 11g: $ srvctl add service d orcl if test - r oel6vm1 - oel6vm2 BASIC EI SESSION m - z 5 AW 60

  Was what you mean?

• 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.

• Horizon 6.0 HTML Blast connection through an A10 load balancer?

  Hey all.

  After a recent update to 6.0.0 of 5.1, we seek to get HTML Blast connections operation.  We are routing our PCoIP connections through an A10 load balancer.  Now, I'm not the person of networking which set up but from my understanding, we have a VIP configuration for port 443 for our two servers for connection.  With the help of the A10, we set up a second VIP with two connection for port 8443 servers.  Load balanced connections to https://myfriendlyname.domain.com half of the working time.  The time, they do not work you can access the destination page, connection, choose the pool, and then page cannot be displayed or couldn't resolve proxy in Chrome.  If you go to the #2 server directly by going to https://server_name , it works fine.  If you go to the #1 server by going to https://server_name/ it does not work.  Both in the Horizon view Admin > servers > server connection > edit > Blast external URLS are https://myfriendlyname.domain.com/: 8443.  If you change this to the individual server, server #1 will always work.  Just like the #2 server.  So I tell myself, is not a thing of VMware, but something of the A10.  I know that a connection initiated on port 443 must be the same server, generating the connection on port 8443, otherwise it will go down.  I checked with our team of networking and check that the permanent sessions are enabled.  We went over a few rounds with A10 and they encountered no HTLM Blast before.  I saw a few workarounds for F5, but nothing for the A10.

  Does anyone have experience with getting this work with A10?

  Thank you.

  Another updated.  We have allowed the persistence of server on the VIP and that solved the problem.

• Help setting up MIrage with load balancer

  I'm trying to configure Mirage to use a F5 load balancer. We simply indicated the Mirage server and received an alias DNS and VIP of the N/W team. I not configure Mirage specifically on an F5 before, should it work without the guard dog service settings configured (at least up to a point where the client can connect)? Or the watchdog service must be configured?

  For setting up F5, we recommend enabling SSL and using SSL session ID persistence, also increase value of persistence for a few hours delay Mirage can be long connected and you don't want them to bounce around. A checkup at the service of Mirage generally configure TCP/half opened on the F5 that verifies that the service of the Mirage port is open. Also enable connections unless the method of balance load.
