Dynamic port channel and load distribution across the interfaces on th trunk.

WS-C3750G-48TS
NOS-12.2(25)SEE2
I have a dynamic port channenl setup on Cisco+NetApp environemt where i have 6 interfaces(1Gbps) on that trunk for load balancing and reduntancy reason.
But i see the interfaces are not balanced on receives or inbound. I mean most of them are going to only 2 interfaces and other four are almost doing nothing.
I am assuming netapp ports serves the way how Cisco instructs. How i can remediate this situation? What am i missing here?

I have alerady mentioned "lacp" in my my last post. Also my understanding  LB is set at switch side , not at filer side. Becase i dont have config at filer side. Also loooking the link there also  dont see a config which says use a particular LB.But the article clearly says to use "ip load balace", no clue though where it is set.  hence my question what is the default LB used/set at switch side. http://now.netapp.com/NOW/knowledge/docs/ontap/rel727/html/ontap/nag/7vifs3.htm https://communities.netapp.com/community/netapp-blogs/sanbytes/blog/2011/12/13/what-value-does-the-leading-fc-switch-vendor-bring-to-ethernet-guest-post-by-brocade http://blog.ioshints.info/2011/04/brocade-vcs-fabric-has-almost-perfect.html may be a good reads i guess.

  • How does failover and load distribution work in Operations Manager resource pools?

    Hello everyone,
    I have a couple of questions in regard to failover and load distribution in resource pools.
    What is the criteria for an x-plat or network device to initiate a failover?
    How is load distributed in a resource pool - Is it round-robin, performance based or something completely different?
    In case more than two management servers are in the same pool, and a management server becomes unavailable, how is load distributed among the remaining resource pool members?
    Any help is appreciated.
    Thx,
    Claus

    Hi,
    Resource Pools are a collection of Health Services working together to manage instances assigned to the pool. 
    Workflows targeted to the instances are loaded by the Health Service in the Resource Pool that ends up managing that instance. 
    If one of the Health Services in the Resource pool were to fail, the other Health Services in the pool will pick up the work that the failed member was running. 
    And I would like to share this article with you. Hope it helps.

  • SGE2010 port-channel and trunking config question

    I have port-channels configured and working for the native VLAN on multiple SGE2010s. I now want to add multiple VLANs and enable trunking for the port-channel. I am not clear on the appropriate way to enable trunking as it can be enabled on the port and on the port-channel. The ports and port-channel are currently in access mode. If anyone can provide the correct configuration, I would appreciate the guidance. I also need to get the port-channels and trunking working with 3Com 4500 & 4200s. If you know of any configuration issues, again any guidance would be appreciated

    Hi Jacqueline,
    Sorry Juans answer needs some correction, but I am grateful for Juans participation.
    The SGE2010 does not support a CLI.
    There is a unsupported CLI,  that someone plastered somehwere on this community, but i must admit i still like to use the GUI.
    The software on the SGE2XXX was recently updated so you can find that on the cisco.com website.
    I have created a link below  to a recording i just made,  regarding Link aggregation on the SGE2XXXX, i thnk if you see the 11 minute recording a couple of times, maybe pause it, play with your switch, it  will start to make sense.
    you can't breat the switch by configuring it
    click here to see a recording of me creating a Link aggregation between two switches

  • Difference between Port Channel and VPc

    Hi Friends,
    Could you please provide the difference between Port Channel and VPC.

    Virtual PortChannel Technology
    Virtual PortChannels (vPCs) allow links that are physically connected to two different Cisco® switches to appear to a third downstream device to be coming from a single device and as part of a single PortChannel. The third device can be a switch, a server, or any other networking device that supports IEEE 802.3ad PortChannels.
    Cisco NX-OS Software vPCs and Cisco Catalyst® Virtual Switching Systems (VSS) are similar technologies. For Cisco EtherChannel technology, the term “multichassis EtherChannel” (MCEC) refers to either technology interchangeably.
    vPC allows the creation of Layer 2 PortChannels that span two switches. At the time of this writing, vPC is implemented on the Cisco Nexus® 7000 and 5000 Series platforms (with or without Cisco Nexus 2000 Series Fabric Extenders).

  • Port Channel Downtime/Convergence time when adding interfaces

    I am looking to add a 3rd and maybe a 4th physical port to an existing port channel as we are running out of capacity, at peak we are pushing around 1.3Gb over the 2Gb channel and we are expanding services out of this location. My question is this, what will the downtime and convergence time be on the port channel when i add in the extra interfaces. Will i drop packets, will my customers notice any service disruption ?
    Currently configured as follows:
    interface Port-channel2

  • Port Channel and VLAN trunking

    When configuring trunking of VLANS accross a Port Channel, do we need to configure vlan pruning on both the port-Channel port and the physical ports ???
    E.g. do I need to apply the "switchport trunk allowed vlan add " command under each physical port and the port channel port ? Or only under the port channel port ?
    Thanks

    In short, yes. Configure the port channel interface exactly as you do the physical interfaces and both ends should be an exact match. otherwise you will have problems getting the channel to come up or stay up.

  • Lines and title flashing across the program monitor and in final export

    I'm seeing very thin lines flashing across the program monitor when playing a complex sequence with 7 video tracks. They draw at various angles and span the entire screen. There can be one or more showing at any time. They are colored and each line appears to be only one color, but different lines can be different colors. Some lines are solid, others are dashed. There is also a ghosty-white representation of one of my titles flashing around the screen for only a frame or two, then it flashes somewhere else.
    Sequences and Tracks:
    Base Sequence: AVCHD with disolves and color correction
    Next Sequence Layer: Base Sequence placed on tracks 1 and 2. Motion is applied to both tracks. LInearWipe and Opacity are applied to Track 2.
    (This creates an image in the center of the screen with a reflection.)
    Next Sequence Layer (1st track of the final 7): Animates Basic3D and Motion (position, scaling)
    2nd, 3rd and 4th of the seven are just like the1st. So there are 4 video screens flying around with reflections and perspective. Kind of like the iTunes album art widget - screen flies in, goes center stage, then flies back.
    Layers 5 to 7 are titles. They are also nested sequences having reflections and Basic3D, but their positions are not animated.
    My system:
    Phenom II x6 1055T
    8 Gb DDR3 1333
    3 Drives 7200 rpm (one program, one preview/conforming, one video)
    nVidia GeForce GTX 260 (3 fans attached)
    3 Case fans plus the side is open - running very cool
    MSI 890GXM-G65 Mobo
    My Project:
    Originated as a CS4 project, opened with CS5 and converted (did not import). Fixed all the title screwups, missing fonts, graphics, hooked up the off-line media etc etc. There are a couple of 1.5 hour nested AVCHD multi-camera sequences which look and play great. Then there are 2 of these monster sequences which are actually used as DVD menus and are about 44 seconds each. When I render these 7 layer menu sequences and play them back, these lines start flashing across the screen.
    Of course the GTX 260 has the GPU unlocked and that works great for the 1.5 hour programs. But if I attempt to render the 44 second monsters Premier stops responding and I have to EndTask it (all CPUs drop to idle while not responding). These monster sequences might test the power of the Quadro CX. So when I work with the menu sequences, I set Premiere to use software GPU and not MPE. Then I can render (2 hours render time to preview 44 seconds with six cores at near 100%). So it does render, slowly.
    I'm exporting an mpeg2 file now and will let you know if the lines show up in the final rendering. I can see the lines showing up on the MediaEncoder's small preview screen as it renders. Doesn't give me comfort.
    OK worst case scenario. The lines ARE in the final mpeg2 file. Makes the file unusable garbage...
    Is anyone else seeing flashing lines and titles?
    Here's a link to a still from the export to illustrate the artifacts.(face and name were blanked out by me)
    http://img23.imageshack.us/img23/5051/premierecs5lineandtitle.jpg
    Thanks

    The crop workaround was successful for removing the lines - worked great. There was the issue of the ghost text which you can see in the screenshot link provided above. This was not removed by crop. Crop removed the lines, but not the ghost. Thankfully, the 4 point garbage mask did work on the ghost and I was able to eliminate it. I had to apply the garbage mask on the sequence where Basic3D was applied not its parent sequence where VerticalFlip was used. The most important thing is that I've successfully migrated this CS4 project to CS5 and can now take advantage of 64bit processing (more RAM) to tame the beast. I'm using this sequence as a menu for a series of DVDs so my time expended will pay me back again and again.
    The asset generating the ghost was built like this...
    In the titler: Text was placed over a logo (.tiff file for logo and it was scaled and moved)
    Base Sequence: Title was brought to two, stacked tracks. VerticalFlip, and LinearWipe were applied to one which was then moved to look like a reflection of the other
    Next Sequence: Layed the Base Sequence down. Applied Basic 3D and moved it's XY position. (This is where I applied the GarbageMask to remove the ghost)
    I tried separating the logo from the text thinking that the logo feature of the titler might be the problem. So I used a separate video track and pulled in the .tiff file directly. It didn't eliminate the ghost. Applying the GarbageMask to the base sequence also didn't help. It was only after Basic3D was applied that the ghost would appear. And since I have Basic3D applied to other reflected text-only layers which do not exhibit the ghost artifact, the bug has something to do with the text/graphic combination with VerticalFlip and Basic3D.
    To top it all off, I can no longer recreate the problem. I've turned off the garbage mask and it's not showing up. While I was testing, the ghost was easy to recreate, but now I can't do it. So I don't appear to be able to drill down deeper. Perhaps it will come back at some point and I can test it further and update this thread.

  • Dynamically generating workflow and relationship images to the Web

    Is there a good toolkit (open source maybe) out there that will allow me to dynamically draw images containing a workflow or show relationships? I only see packages that are geared for charts, I want to dynamically draw the dependency between 2 or more objects on the fly. To be able to do that I need to be able to draw rectangles (2 or 3d), lines with ends (as in Visio or something) and draw text in the box representing the entity name. I don't want to have to code all this myself using BufferedImage etc. Looking for a nice little toolkit.
    Thanks
