• Reference Dell PowerConnect 8024 - 802.3ad (dynamic LACP) through 2 switches?

  We evaluate the use of switches Dell PC8024 to upgrade our backbone to 10GbE.  We use currently HP ProLiant servers with multiple network cards are associated.  The servers support 802.3ad HP dynamic aggregation of links (LACP).

  The switch PC8024 does support the aggregation of dynamic links through 2 different switches, or should it be on the same switch?

  In comparison, the HP2910 switches can support aggregation (LACP) dynamic links across multiple switches, while the HP2920 switches can.  If some can, some can't.  Need to understand the ability of the switch to PC8024.

  Thank you!

  Hello Terry,

  The 8024 does not support a SHIFT of two different switches, the only way it would work, if the switches are stacked and effectively a single switch. If you have used the new series N4000 they take over MLAG, allowing for the OFFSET will be in both switches and they communicate via a peer.

• The GS324 supports 802.3ad Dynamics?

  I am looking to buy a Nighthawk R8500, and a switch of 24 ports of GS324 for my home network. However, I have found no information to indicate whether or not the GS324 supports double AD ports on the router R8500. It would really cinch the purchase for me, otherwise I'm on the fence.

  Does anyone know if the switch supports? If not, what switch would be recommended to get that extra bandwidth?

  Hello DasMainframe,

  Welcome to the community!

  The GS324 switch is only a (silent) switch passthrough and I do not think that it supports the LACP Protocol. It is not configurable, since she does not have any user interface or management software. If you want a switch with LACP (802.3ad) you have to go with our Smart Switch (PROSAFE series) models.

  Let us know if you have any other questions.

  Thank you

• 802.3ad on switches

  We have bought just 6224 2 switches but neglected to buy the parts stacking. Can I do 802.3ad (aggregation of links) through the switches without stacking connectors? (Plug 1 cable into each switch and have a trunk between the two)

  And if it does not, it will be if I use the stacking connectors?

  Thanks in advance,

• 802.3ad link Aggregation - 4 NETWORK cards

  I'm working on a project that requires four physical NIC be connected to two separate Cisco switches for redundancy.  I need access to a minimum of six networks through these four physical NETWORK card ports using ESX 3.5.

  Our plan is to use the Routing and aggregation (Etherchannel) on Cisco switches.  What we want to do is basically aggregate two NIC physical port trunks to each of the two switches Cisco Etherchannel.  We would allow routing based on IP hash on the unique vSwitch with four network adapters are associated.  We would use a separate vSwitch for vSwif0 and vmkernel port not part of the trunks.

  Seems this configuration good to you?  Looking for networking people comment on the above configuration.  Thank you.

  This is a discussion that asked the same question.

  This is an insertion of the blog of Kevin Cline.

  http://kensvirtualreality.WordPress.com/2009/04/05/the-great-vswitch-debate%E2%80%93part-3/

  A technical requirement for the use of hash of the IP, it's that your physical switch must support 802.3ad static aggregation of links. Often, this means that you have to connect all the natachasery in the vSwitch to the same pSwitch. Some switches high-end support links grouped in pSwitches, but many do not. Contact your switch vendor to find out. If you do not have to put an end to all the natachasery in a single pSwitch, you introduced a single point of failure in your architecture.

  If your provider supports the links grouped in all of pSwitches, great.  Otherwise, you may need to consider another approach.  You can have redundancy between switches without etherchannel and just routing based on originating port ID.  So you could create a vSwitch with 4 NICs (two on each pSwitch) without a trunk and let ESX base for outbound traffic load balancing.  From my experience, you are much more likely to be CPU or memory bound as bound network.

• DVS does support LACP 802.3ad?

  Hello

  Could someone let me know if DVS supports LACP (dynamic negotiation) 802.3ad. I know that vSwitch he has not supported.

  Thank you

  According to this document, only the Nexus 1000V supports LACP

  http://VMware.com/files/PDF/technology/cisco_vmware_virtualizing_the_datacenter.PDF

  There is a table that shows which features are available on each type of switch.

  The only thing to look at will be the VLANs that you got set up on the vSwitch. You have defined VLAN native example, the VLAN untagged on the switch to be 4094, any traffic sent on the aura tags trunk VLAN, which will be removed by the vSwitch.

  In my setup, I have established groups of ports using VLANS and VLAN 2 10. Traffic to the virtual machines on these VLANs are .1Q marked by the physical switch, which is then stripped by the vSwitch.

  Take a look at the section "VLAN in VMware Infrastructure" on page 7 the concepts of virtual networking André already mentioned, but also the other interesting reading material is http://www.vmware.com/pdf/esx3_vlan_wp.pdf.

  Finally, for the side of the switch of things, look at the examples on Scott Lowe's blog at http://blog.scottlowe.org/2006/12/04/esx-server-nic-teaming-and-vlan-trunking/.

  Concerning

• NIC teaming on ESX4.1 with Dell PowerConnect 2816

  I'm stuck trying to get partnering work... I hope someone can help!  I'm under ESXi 4.1 (vSphere), on a server with 2 GB for a Dell PowerCOnnect 2816 cards, supporting 802.3ad

  Here's what I'm doing and the result:

  1. I added a second NETWORK adapter under vswitch0 properties (in ESXi 4.1)

  2. I went to vswitch0 |  Port properties then the consolidation of NETWORK cards and set the active adapters and as road based on IP Hash load balancing

  3 apply/close my way and ESXi now shows 2 map NETWORK interface connected to the vswitch (and everything still works fine).

  Question 1: Shouldn't I lose connection to ESXi at this point?

  4. I go to the page OpenManage and have setup a group LAG (1) with load balancing the value "Layer 3" (which should be the IP Hash I think)

  5. I add 2 ports to the LAG group

  6. I lose my connection to the server.  If I remove the ports in the Group LAG then the connection comes back.

  ABOVE 2: why the connection disappear?  Expected the cluster NIC sync/speak to the LAG on my switch?

  1: you can always access ESXi through TSM (Tech Support Mode) of the local console. This article explains how to:

  http://KB.VMware.com/kb/1017910

  If something goes wrong and you need to reset the network configuration, you need the command-line tools esxcfg-vswitch and esxcfg-vmknic. See the help pages for these commands for more details how to use (there also many guides online as http://www.2vcps.com/2009/11/22/esx-commands-esxcfg-vswitch/)

  Also, there esxcfg-cfgbackup who should be able to create a backup and restore it later if necessary, but I have never used this before ordering. Seems simple.

  2: I do not think that it is replaced by default, it should inherit the policy level superior vSwitch.

• Airport Extreme Gigabit Ethernet and Jumbo frames

  Hi all.

  Can anyone support me kindly about Gigabit Ethernet & Jumbo Frames with Airport Express?

  I currently have and use a 5th generation Airport Express and you want to buy the QNAP TS - 453 Pro NAS. In any implementation of storage NAS, Gigabit Ethernet, the frames extended as matching Ethernet card well, are all very important to achieve broadband performance, so my questions are:

  5th generation Airport Express

  
  

  • Are the NETWORK Gigabit NIC Ethernet card?
  • It also works with extended frames (QNAP NAS supports 4074, 9000 and 7418 bytes for MTU)?
  • QNAP can trunk NIC (if more then one) with the following options:
    • IEEE 802.3ad (dynamic link aggregation)
    • Balance-tlb (Adaptive Transmit Load Balancing)
    • Balance-alb (Adaptive Load Balancing)
    • others (mainly for failover)

  Is 5th generation Airport Express enough or should I think about moving to the 6th generation?

  Thank you.

  You mix up the terminology... Express and Extreme are totally different.

  The title is correct... Extreme... your question text replaces by Express... they are only 10/100... and gen only 2 of them.

  Any airport extreme Gen2 - Gen6

  Use the Gigabit ports.

  Do not support jumbo frames

  Do not support pairing.

• 2808 LAG for use with VMware ESXi and Linux collage

  I posted the month last about setting up my work with groups LAG http://en.community.dell.com/support-forums/network-switches/f/866/t/19537080.aspx servers (I'll effectively implementing implement this Saturday)

  I decided to buy a 2808 for my ESXi server get more aggregated connections to my staff iSCSI Linux server but now I'm worried I might have made a mistake to buy the 2808.

  After looking in the manual before I realized I could have been mistakenly assuming that the 2808 had STP and LACP, as I can't find LACP anywhere in the PDF file. I guess that the configuration of my Linux machine for 802.3ad is out (a hope to make mode 4), so now for the configuration of my house, I wonder (* 1 *) that I have to configure my VMware NIC team like and what mode of binding should I use on my Linux host? As for the section at the top (my working configuration) (* 2 *) I don't know what to do about the road other than the leave as 'route based on originating virtual port ID "? (This is how our other data centers are configured, but I'm waiting for my admin network as agglomerates ESXi hosts are configured with the channels of port on our cisco switches)

  For the House, I want to try to increase the bandwidth by using three NICs in each server, I was hoping that it works:
  VMware: Route of IP hash function?
  w/Linux: balance-alb?

  -VMware:
  Before you begin:

  • The default load balancing strategy is route based on the port virtual origin ID. If the physical switch uses the aggregation of links, route based on the IP hash load balancing should be used. For more information, see host requirements for the aggregation of links for ESX and ESXi (1001938) and the guide of VMware Virtual Networking Concepts .
  • LACP support was introduced in vSphere 5.1 on distributed vSwitches and requires additional configuration. For more information, see activation or deactivation of LACP on a group of ports Uplink using the vSphere Client Web (2034277).
  • Ensure that the Protocol of aggregation VLAN and link (if any) are correctly configured on the physical switch ports.

  -Linux:
  * Descriptions of bonding modes *.
  + Mode 0 balance-rr: Round-robin policy: transmit packets in the sequential order of the first available through the last high school. This mode provides load balancing and fault tolerance.

  + 1 active-backup mode: Active-backup policy: only one slave in the link is active. A different slave becomes active if and only if, the active slave fails. MAC address of the binding is visible from the outside on a single port (NIC) to avoid confusion between the switch. This mode provides fault tolerance. The first option affects the behavior of this mode.

  + 2 balance-xor mode: XOR policy: transmit based [(adresse MAC XOR avec destination MAC traiterait de source) modulo County slave]. This selects the slave even for each destination MAC address. This mode provides load balancing and fault tolerance.

  + 3 broadcast mode: broadcasting policy: transmits everything on all slave interfaces. This mode provides fault tolerance.

  + Mode 4 802.3ad: IEEE 802.3ad dynamic aggregation of links. Creates aggregation groups who share the same speed and duplex settings. Use all the slaves in the active aggregator according to the 802.3ad specification.

  -Prerequisite:
  -1.Ethtool support in the base drivers to retrieve the speed and duplex of each slave.
  -Switch 2.A which takes care of IEEE 802.3ad dynamic aggregation of links. Most of the switches will require some type of configuration to activate 802.3ad mode.

  + Mode 5 balance-tlb: Adaptive load balancing transmission: Channel link that doesn't require any special switch support. Outgoing traffic is distributed according to the intensity of the current (relative speed) on each slave. Inbound traffic is received by the current slave. If the receiving slave fails, another slave takes over the MAC address of the failed receiving slave.

  -Prerequisite:
  -1.Ethtool support in the base drivers to retrieve the speed of each slave.

  + 6 balance-alb mode: Adaptive load balancing: includes balance-tlb plus receive balancing (rlb) for IPV4 traffic and doesn't require any special switch support. Receive load balancing is achieved by ARP negotiation. Link driver intercepts the ARP replies sent by the local system on their way and replaces the hardware address of source with the unique hardware address of one of the slaves in the bond as different counterparts use different physical addresses for the server.

  The topic dell nearest you, I have found a useful was: http://en.community.dell.com/techcenter/networking/f/4454/t/19415629.aspx

  my previous post was more concerned with VLAN tagging and spanning tree issues, but now I see I should have feared groups LAG it as well.

  Any help would be appreciated, thanks in advance all :)

  -

  PS. http://i.dell.com/sites/doccontent/shared-content/data-sheets/en/Documents/dell-powerconnect-2800-series-spec_sheet.pdf said that the 2800 series supports LACP, so if I'm worried about anything on my iSCSI side slap me please in the face, but I guess even in this case, I'm still not sure how to configure the ESXi host because it does not support LACP without vSphere and my original configuration is a free version , so I have no web vSphere management needed to make the LACP allow the change.

  Not sure if it is of no use: example configuration of EtherChannel / switches control protocol LACP (Link Aggregation) with ESXi/ESX and Cisco/HP (1004048), but that's where I was to base the choice on IP hash from.

  It must have the support of layer 3 to achieve IP hash, IP addressing is a 3-layer technology, so a 6200 series or higher or the soon to be released N3000 series.

• Server 5.0.4: Too many users connect to file sharing

  Hello

  First of all, here are my current profile:

  Mini Mac server (end of 2012)

  OS X 10.10.5

  Server 5.0.4

  Lately when I am looking at the list of users connected to the server via the tab sharing files I noticed more and more users who connect to Time Machine to back up at the same time. When there are so many users doing this that it slows everybody back down.

  Is there a way I can strangle the number of users connected at the same time?

  I don't believe it.

  Perhaps you should consider setting up more than one time server Machine and distributing users between them. It would be probably exaggerated, but in theory, you could have two or Mac connected to a San to share a storage pool and each being then a time server Machine. I'd probably use independent storage for everyone in this case well unless you already have a SAN system.

  You might also consider bonding of two or more network interfaces on the Mac mini to give it a faster network connection or more money there today Thunderbolt 10 Gbit/s Ethernet adapters.

  2 x 1 Gbit/s = 2 Gbit/s, or 1 x 10 Gbps is clearly going to be able to support more network traffic and so more users than just the single integrated to 1 Gbit/s Ethernet port. You need a network switch that also supports Ethernet 10 Gbps, or LACP aka. 802.3ad as the standard of channel binding depending on the approach you have chosen.

• Support for the 'grouping' Dual LAN

  I bought a router of WRT600N, which was far & away the router wireless dual band to use more expensive (& only) available at the time + 2 compatible Ultra Range Plus USB receivers.  Apparently Linsys/Cisco decided to abandon this model & more support - still firmware version 1.0 (from 2008).  OK, then repeat ceMarketing not high on their priorities.

  I recently upgraded my hardware in a platform Intel 1156 running Win 7 Ultimate 64-bit completely.  The new motherboard, a Gigabyte GA-P55-UD5, has a 'dual LAN' support that allows "bundling" - potentially 2 GB support & self-switching if a port is not functional.  Apparently, it requires a router that has 'IEEE 802.3ad' capabilities.  As far as I can tell, this potentially interesting feature only is not supported, & the firmware upgrade failure suggests it will be never. - bought their "Network Magic" software Pro to add another $50.

  So the question is this: I believe - no double support LAN is built in & never will be--or is there a way to use this feature?  Suffice to say, if I paid about $420 for the router & USB receivers where if other router support him on the level of consumption, I will never consider a Linksys/Cisco product in this life.

  Thanks for some clarity - that someone has to offer.

  I would say the associations are no consumer router function. If you really need a connection of 2 Gbps to a single device to your network, I wonder what other device to communicate with this speed. It is not only another device because it would have only 1 GB/s unless you team two remaining ports as well. (Do not forget that desktop computers more level of consumption are not yet fast enough to offer or receive data at a rate even if they have a Gigabit ethernet port).

  If you have a set of other features which, in combination, require 2 Gb/s access server, then you will have again the same problem: it must connect somewhere which means you need a switch that must be connected to the two remaining LAN ports. But then, you might as well get a switch that supports reunification and enough ports and connect everything what he. Of course, an ethernet switch that supports the grouping is usually some 'smart' managed switch that cost easily more then your WRT600N.

  So I think that grouping will be never supported on any Linksys consumer device. If you then you must watch the Cisco Small Business series or better. They have some devices supporting 802. 1 q VLAN and therefore potentially also 802.3ad. Although even in this case I doubt because given the number of ports available on these devices is not really a lot of sense to support at least on a router 4 ports. Devices consumer and SOHO are not for internet connections of 1 Gbit/s or more. So you can only use the speed inside the LAN, but with 4 ports that would be difficult... So I would say that by their design these routers don't support grouping. If you need grouping within your LAN, get a managed switch...

  Currently I see many MAC beat in the log of the switch.  From my understanding, I expect the MAC address out all ports, because that's what'd ESXi when you use 'route based on the hash of the IP.  I'm worried about the impact this might have on the CPU / switch.

• LACP SG200 - 08 double speed ethernet when two aggregation of links Mac it

  Hi guys, I use a mac mini and imac with 2 Thunderbolt ethernet adapter to make the aggregation of links on a SG200-08.

  To copy the files of drivers from the mac mini raid0 stroke, the speed of the network can reach 225 MB/S, but the actual speed of the disk drive is only 107 MB/S

  I mean that the two ports in each mac carry only the same data over time. Can he do a given separate two and carry on two ports?

  I can find use VLAN or else combine two IPs for one?

  Don't know how yo SG200-08 GUI web definition (this is my first time using the smart switch)

  Hi Yang, your computer supports a load such as link aggregation/LACP 802.3ad balance method? You can effectively double the data rates without a nic-team aggregation technology or link any.
