Etherchannel sequence

Hi Experts,
I would like to know the Etherchannel sequence.
If I have 2 ports in EtherChannel, for example, port 1 and port 2.  Source and destination mac is my load balance method.  I would like to know when the first packet goes to the Etherchannel, which port that the 1st packet will go, port 1 or port 2.
I am sure it would only go by one port for each session, and I wonder which port it would take when the first packer arrives. 
Thank you,
Aries

Hi Aries,
Nice question.
I just now did three experiments on this and at the three times... the first frame has passed throught the port with the lowest number.
For ex:
My first port-channel has Fa0/1 and Fa0/2 ,,, the first frame passed through Fa0/2.
My second port channel ex: There were two ports already in channel they were Fa0/14,Fa0/15... fa0/15 was first added to the channel... but the frame chose Fa0/14 for the first time.
My third ex: There were Fa0/15 and Fa0/14 channels... then after i added Fa0/1... the first frame chose Fa0/1.

Chandu

  • Switch ports did an up/down sequence after being placed in etherchannel with no cables connected, wierd.

    Hi Everyone
    I created an etherchannel on two ports (2960 switch) and placed them into an etherchannel.  Did the same on the other switch Cisco 3020 blade chassis switch.  Without connecting any cables the 2960 had done an up/down sequence as though a cable had been connected and yet this had not been done.  Can someone try and help with what could be the technical explanation of this interesting phenomena.  the etherchannel was a trunk and the ports were sitting in vlan 200 and this vlan was also configured as the native vlan for the trunk.
    Please,  please help - any comment is appreciated.

    Hi Sydney,
    It can be possible that speed and duplex setting between the switches are not in sync. Configure all interfaces in an EtherChannel to operate at the same speeds and duplex modes.Enable all interfaces in an EtherChannel. If you shut down an interface in an EtherChannel, it is treated as a link failure, and its traffic is transferred to one of the remaining interfaces in the EtherChannel.
    For EtherChannels:
    –Assign all interfaces in the EtherChannel to the same VLAN, or configure them as trunks.
    –If you configure an EtherChannel from trunk interfaces, verify that the trunking mode (802.1Q) is the same on all the trunks. Inconsistent trunk modes on EtherChannel interfaces can have unexpected results.
    –An EtherChannel supports the same allowed range of VLANs on all the interfaces in a trunking Layer 2

  • EtherChannel between cisco devices need help

    Hello,
    At our company we use 2 asa 5525 firewalls in active/standby mode.
    Both of them are connected to a single cisco router.
    The goal is to have the cisco router to automatically send traffic to the active firewall (regardless which firewall is active at that point).
    To solve this would it be possible to create an EtherChannel with 2 ports on the cisco router and then have 1 link going to the active firewall and 1 link to the standby firewall.
    If the active firewall fails and the standby firewall takes over, will the standby firewall receive all the traffic that normally would go to the active firewall without any downtime?
    Will this work or does another solution exists for this? Its important for us that the hosts on the network suffer small to none downtime at all.
    The topology can be found in the following image.

    Hello
    "You could possibly use bridging on the router which would allow you to  have two interfaces on the same router in the same IP subnet and connect  one interface to the active firewall and one to the standby. But i  cannot say for sure this would work as i have never done it with ASAs"

  • Etherchannel issue between 3750 stack and WS-CBS3012 for IBM blade centre

    Hi,
    We are trying to configure Etherchannel between four ports of cisco 3750 stack(2ports from one switch of stack and two ports from another switch of same stack). We are facing issues with this setup. The ports in WS-CBS3012 are going to err disable mode.
    Is  there any limitations associated with such a cross-stack etherchannel configuration. Please suggest if there is any particular sequence of configuration involved.
    Switch1 in stack

  • Why self-defined access sequences of free goods can not work?

    Hi gurus,
    I have maintained access sequences of free goods self-defined.but when i creat the SO it does not work!
    when i used the standard access sequences ,it is OK .
    Can anybody tell me why?
    thanks in advance

    Dear Sandy,
    Go to V/N1 transaction select your self defined access sequence then go in to the accesses and fields and check all fields are activated.
    Make sure that these fields are flowing in your sales order.
    I hope this will help you,

  • Is there a way to create a renaming preset where the sequence starts at the number "0" zero?

    What I am trying to achieve is the following:
    Fro example, I am photographing a handbag and I need to rename the file using a barcode and a barcode scanner.
    My sequence of images goes like this:
    Image 1: Tag shot
    Image 2: Front
    Image 3: Back
    Image 4: Inside bag
    Let's say the barcode once scanned produces a code such as TRE8801AZT16-Z
    Right now my current preset is "Custom Text_Image # (1)"
    This results with the images being renamed as:
    TagShot: TRE8801AST16-Z_1
    Front: TRE8801AST16-Z_2
    Back: TRE8801AST16-Z_3
    Inside bag: TRE8801AST16-Z_4
    What I need is the sequence to start at zero so the tag shot is _0 and my images are named like this:
    TagShot: TRE8801AST16-Z_0
    Front: TRE8801AST16-Z_1
    Back: TRE8801AST16-Z_2
    Inside bag: TRE8801AST16-Z_3
    Is this possible? If yes, how?
    Thanks for the help

    About as close as you can get is to right-click on a single clip and Make Multiclip Sequence. Hit OK to make an sequence out of the single clip. Open the sequence made and delete the multiclip and edit the clip you want back into the sequence.

  • All of a sudden I can no longer toggle or clip angles in multiclip sequence

    Hi,
    I've got a project with a number of sequences, videos, angles, etc and all of a sudden I can no longer toggle between angles in the sequence timeline. It was working last night and then stopped and it's still unresponsive. Every time I click to switch an angle or cut to an angle I get the alert beep.
    I am not out of disk space and haven't changed any settings as far as I am aware of.
    Thanks

    Not sure what the deal is...have you added any new software or upgraded/updated anything since this started?
    Have you tried opening an autosave version, to see if it works there?
    Trashed prefs, run disk utility?
    I'm not sure I've ever heard an 'alert beep', so would wonder if the drive is failing.
    Can you be a little more explicit about exactly how it 'stopped working'...were you right in the middle of working on it, or had you stepped away for a bit?
    Have you tried shutting down, then rebooting after 15-20 minutes?

  • New Access Sequence for Free Goods Determination

    Hi Guru's,
    I Have  a scenario wherein i have to maintain the free Goods Condition records in VBN1 with a new access sequence namely Customer/Distribution Channel/Plant/material.
    I have maintained all the necessary settings such as Free Goods Activation for Item Category, Assignment of free goods pricing procedure to my sales area,Positioning of R100 condition type in my pricing procedure with relevenat routines.
    At my Sale order level after maintaining the free goods condition record in VBN1 in new access sequence, my free goods determination is not happening and at the sme time if i maintain it in the standard access sequence i.e. in Sales Org/Dist.Channel/Customer/material the free goods are getting determined.
    Can anybody help me out in this..
    Regards
    Bhushan

    Hi
    There arew 2 things to be done or checked
    1. Position your access sequence before the standard one by giving step nos accordingly
    2.In the existing sequence check for the exclusive indicator in the standard sequence and i think that is ticked in your case
    Hence after getting the condition record in the standard sequence the system stops searching for the new records in your new access sequence
    If that is the casethen remove exclusive indicator from the standard one and tick the same in your new access sequence
    By this you can get the condition records of your new access sequence without positioning
    Pls reply whether mu suggestion has helped you

  • How to keep messages in sequence of different interfaces (using queues?)

    Dear experts,
    I'm running a scenario in which a job in one system creates and deletes orders in another system via XI (using idocs). I'm sending 100 times more creations than deletions.
    These are two different interfaces. Therefore they use different queues.
    My problem now is that sometimes a deletion enters the target system before the the creation of this order has taken place. Because the queue is much shorter for deletion, these are processed earlier.
    How can I make sure that message from two different interfaces enter and then exit xi in the same sequence? Is it possible to assign them to the same outbound queue?
    Please advice.
    Thanks in advance.

  • How to? Populate sequence in 2 Entities comprising 1-1 View Object

    Hello all,
    In my DB model, I have modeled sub types of an entity by having a main table with the common fields and then separate tables (with 1-1 relationship) to the main table with the fields that are specific to each type. Each of these tables has an ID column as the PK. I have created a trigger on the main table to auto-populate the ID from a sequence. If I have a VO based upon 2 of the entities (in a 1-1 relationship), how can I get the sequence # from the main table in order to populate the specialized table?

    The TreeViewAdaptor is responsible for mapping your custom data to the tree view itself.  I almost always start by making it return some fixed number of objects with names "item 1" etc. That way you get the tree view working first.
    Then, after you get it laid out and displaying properly, you can worry about using real data.  At that point, you have your adaptor return the actual number of items in your list and each individual item.  Then you can populate your list when you push your button and then invalidate the IControlView of the tree view widget to cause it to redraw.  At that point your adaptor will get called and your data should appear.

    We have sequences which create values used for Primary Key. We are on the process of creating replication between Oracle Databases.

    My question is do I need to follow those steps for online change synchronization also? Or we can skip ?

  • Media Encoder CC won't import a JPEG sequence to the queue

    I am running Media Encoder CC 7.2.2.29 (64-bit) on OSX 10.9.4.
    I have a JPEG sequence GoPro timelapse image sequence that I want to encode into a video clip. All files have a .jpg extension. They are 4000x3000 and have an RGB color space. The Color profile is SRGB IEC61966-21. All images are 3.9MB.
    According to the ME help I should do the following.
    To add an image sequence, choose File > Add Source. In the Open dialog box, choose the first file of the image sequence. Enable the  Sequence Import checkbox for your file type, and then click the Open button.
    I follow the instructions and select the first image in the sequence. The "JPEG File Sequence" checkbox is active and I check it and click the Open button. The dialog disappears and nothing happens. There are no warnings.
    How does one get JPEG sequences to import to the queue?
    Please advise.
    -Travis

    Yes, import into premiere work fine. The nice part about using AME directly is you don't have to have to create a project or use an old one every time you want to crunch a timelapse. Also, AME has this nice feature where it will autoname the output file IMG[FirstStill]-[LastStill] (ie IMG[GP001234-GP001297]). This was helpful because GoPros change the first number in the sequence every time you stop and start time lapse.

  • Media Encoder CC 2014 using cached versions of Precomps in AE and Nested Sequences in Premiere?

    I'm seeing this weird thing where Media Encoder is using older versions of certain assets when exporting a Premiere Pro CC 2014 sequence.  I'm seeing issues with nested sequences...Media Encoder uses an old version of a linked AE comp or it doesn't render a certain video track. With linked AE comps...I'm seeing Media Encoder use an earlier version of a precomp within the main comp.
    When I look at the video in the Export Settings dialogue in Media Encoder, the old version of the AE comp shows .
    If I look at the Export Settings dialogue in Premiere, it's up to date and looks right.
    Anyone dealing with this or found a workaround?  Thanks!
    Calvin

    I don't think I'd call this issue expected behavior...at best it's anticipated behavior that's going wrong.  The only reason I wouldn't call it expected behavior is because what I'm seeing is AME reverting to a cached state on a FRESH LOAD of a sequence to render directly from Premiere.  Basically, AME isn't open...sequence looks fine in PPro...load into AME via PPro export...look at export settings dialog in AME and note that the sequence is the old/cached version.  So, it's not like the export was already in AME and THEN I made changes in PPro.  It appears AME might be incorrectly identifying the newly imported sequence for export as an older, cached version.
    However, I didn't get a chance to test your original solution so I'll try that the next time I see it happen.  I also fixed the issue by clearing out the media cache and databases.  NOT an elegant solution at all and TOTAL overkill...but it did work.
    Thanks for the links!
