Group of channels on 2 switches

I have 2 24-port Catalyst 3560 switches (call them, one switch and switch-b).  They are connected together by a cable connection and not stacked (the c3750 is stackable but not the c3560). Is it possible to have a group of ports-channels with 2 ports, where a port is A switch and the other is the B switch?  If not, is it possible if 2 switches are stackable as c3750 switches?  Thanks in advance.  -Sam

Hey Sam:

Stacking, in the sense used by the 3750 switches and channel groups really have nothing to do with each other. Of course the 3560 cannot stack in this sense, but groups of channels are certainly achievable on these switches.

However, if you want to split the Group of channels so that half is on a switch and half is on the other, requiring correct stacking. This works on a set of 3750 switches stacked certainly, but will be not feasible on two 3560 units.

  • Added properties (Group and channel) are not a numeric data type.

    I use a use to add two groups and channel custom properties. The properties are text and digital, double and whole.

    You don't have to delete the files.  Choose the NAVIGATOR menu "settings > My DataFinder > reset... '. "can clilck on the UPPER part of the two buttons, one called"reset the index.  Which will remove all records in database and re-index all of your data files.  If you one of these properties have already optimized, set their State not optimized before resetting the index, otherwise the optimized property data types will persist.

    If this does not help, then the problem could be in the use that you use.

  • Remove the port from the channel-group

    I met a strange problem with port aggregation, where I decided to remove a port of a port channel and put it in another, but in my SNMP tool, it still belongs to the old channel of port and the new at the same time.

    Port channel was created using:

    (config) #interface gigabitEthernet 0/1/22

    (config-if) trunk mode #switchport

    (config-if) active in mode #channel-group 1

    Then passes through

    (config) #interface gigabitEthernet 0/1/22

    (config-if) #no active mode channel-group 1
    (config-if) active in mode #channel-group 2

    I have also that when I pull up some information on configuring etherchannel.

    This could be a problem with my (observium) snmp tool or are there additional measures to eliminate a port of a group of channels? Reboot of the switch?

    System image file is "flash: c2960s-universalk9 - mz.150 - 2.SE4.bin.

    Hello

    I would say that it is related to the snmp tool, once you remove the port of the chain earlier and added to the new, which will be to the one, it is impossible that an interface will be less than 2 different port channels.

    Also there is no need to restart the switch or something like that, you can use the following commands to verify that the interface is now part of the new channel group:

    Show etherchannel summary

    Show interface execution item in gi1/0/22

    With these commands, you will see that the interface belongs to the Group channel 2, and the order that you set above shows that the interface belongs to po2.

    Hope this helps

  • Series quick reading of the channel group properties

    Hi, can someone please advice what is the fastest way to extract about 400,000 files channel group properties? Currently I use DataFileLoadRed with only the Group of channels that interests me and channels stripped down to a single value by setting the no. intervals of 1 and SectionBegin / end of 1/2. Suggestions for improvements? PHEX

    An alternative would be to open all files with the following code.

    Option Explicit
    
    dim groupindex : groupIndex = 1 ' you can also use a groupname instead
    dim groupProperty : groupProperty = "description"
    
    ' include this in a loop over all your files
    dim filePath : filePath = "C:\temp\example.tdm"
    dim store : set store = navigator.ConnectDataStoreByParameter("TDM", ""& replace(filePath, "&", "&") & "")
    dim propVal : propVal = store.RootElements(1).Children(groupindex).Properties(groupProperty).Value
    MsgBox propVal
    

    The files are open and your properties are extracted. Potentailly datafinder approach should be more fast but if you don't get that market this may be a way out.

  • Lacp 3560 switch circuits

    I'm trying to run a trunk on a four port Lacp group to a form of switch netgear a 3560 but am stuck. Everything works fine if I place a chest with a single autonomous port, and that everything works when I use a group of Lacp 'switchport access' mode, but as soon as I activate "switchport trunk" each gi status goes to "suspended" and no traffic flows.

    Does anyone have any suggestions?

    Thank you.

    Andrew,

    Thank you for the additional information. The configuration of the ports seems to be ok now.

    After the Show etherchannel , physical ports are individual-State. This would mean that the switches did not negotiate the creation of the Association using the LACP Protocol and ports still work as four individual switchports.

    The neighboring switch talking LACP? If he is put in LACP active mode? At least one device must be in LACP active state, and both must talk to LACP. Maybe you could try to replace orders 1 channel-group passive mode 1 mode channel-group active in your configuration.

  • Several groups Etherchannel summary

    I have a strange problem with a port-channel configuration on my 6509 (IOS 12.2 (33) SXI4a) with redundant Sup720s.  Before going much further to try to remedy through experimentation I wanted to receive feedback from others, in case anyone has seen this behavior.  I think I know why it happened, but I would have preferred to better understand the reasons and also the best way to solve it.

    We have a lot of servers in our environment configured with double copper 1 GB interfaces running in a configuration of Etherchannel delivered to our core 6509 switch.  We use LACP (assets) to support reunification between switch and servers

    We started with some WS-X6148A-GE-TX-line cards installed in order to support the lower flow of our servers at the same time and save money.  These line cards are oversubscribed on a ratio of 8: 1 as far as bandwidth goes, and we received with this for quite a while.  It emerged last year that we had heavy - hitting a few servers that receive many a fallen executives as contactors interfaces were not able to follow, if we bought a WS - X 6748-GE-TX line card that is almost full-speed capable line by port.

    Because we wanted to migrate these servers to the new card online with minimal downtime I thought the easy way to do the following:

    (1) put two interfaces on the line-new map in the same group of port-channel ports currently in use for this server.

    (2) move a cable in one of the new ports and wait to get online in the bundle of this port.

    (3) move the rest of the cable in the port of other new and confirm that it delivered.

    (4) remove the two old ports on the map in slow-line of the config of the channel port.

    Using this method with two servers to work pretty smoothly without breakdown in communication to servers.  However, I seem to have some odd leftover information in my config bothering me.  Here is an example:

    den-sw35aa #sh etherchan 36 short

    Flags: - Low P - D bundled in port-channel

    I have - autonomous s - suspended

    H Eve (LACP only)

    R - Layer 3 S - Layer2

    U - N running - is not in service, no aggregation

    f cannot allocate an aggregator

    M not in use, no aggregation due to minimum links has not met

    m don't use, port do not associate due to not meeting minimum links

    u - unfit to tied selling

    d default port

    w waiting to be aggregated

    Number of channels: 35

    Number of aggregators: 37

    Protocol for the Port-Channel port group

    ------+-------------+-----------+-----------------------------------------------

    36 Po36 (SD) LACP

    Po36A 36 LACP Gi2/9 (P) (SU) Gi2/19 (P)

    Last applied Hash Algorithm of Distribution: fixed

    As you can see, I have now two groups under this configuration of etherchannel port-channel.  No ports are assigned to the original Po36, and the new Po36A contains the two new ports.

    It also shows that I have 37 aggregators and only 35 groups of channels actually in use.  I wonder if this is going to happen with all the servers that I have to do and, ultimately, reduce the port channel groups total I can configure and I used.

    My idea of why this could have happened back to fundamental differences in the line cards themselves.  Going enabled card of tissue non-tissu a permit probably was a little too wait for a package of four way occur when I put all four ports in the group.

    As much as to get rid of him, I think to close the interface port-channel itself, then physical, then all ports put up in reverse order.  I hope that it would not come down to close the ports and left-hand config port all channel and reconfigure.  At worst a switch reboot, but it's absolutely a last resort, and if I were to conclude that it was to have some sort of negative performance impact.

    No previous experience or input would be appreciated.  I was unable to find anyone in the forum regarding documentation and a similar story has not received me any where.

    Best regards

    And for you to remove the aggregation switch reload or flapping interface would not help. I'm afraid you will have to reconfigure the portchannel again. It's the only way you can get rid of it.

    I hope this helps.

  • Grouping of NETWORK cards causing the ESXi to retransmit ethernet frames received.

    I had an HP Proliant DL380 G5 ESXi 5.1.0 connected to a Cisco 3750 Switch stack.

    All by performing a tcpdump on a host without a report, I discovered that he was under the bombardment with ethernet frames for the MAC address of a computer virtual located on a host across the data center. After a few brief troubleshooting, I discovered that I was able to stop those erroneous frames by disabling NETWORK adapters on my VMWare host group.

    I believe that in my situation when ESXi is configured to use two network cards to all frames received on vmnic0 and retransmits them on vmnic1 and vice-vesa. I experienced these symptoms when ESXi is configured for failover with an active adapter and adapter mode standby and I also experienced the same symptoms in the following load balancing configuration.


    Symptoms: some time after activating the load balancing, all frames Ethernet for the MAC address of a virtual computer on the affected host are broadcast on each switch port in the entire data center.

    Steps to reproduce:
    (1) implementation below configuration.
    (2) unplug the ethernet cable connecting vmnic1 and switch1 port gi2/0/4
    (3) run the host 1.1.1.1 EI - n - q tcpdump on any machine physics linux in the data center (don't even have to be connected directly to 1).
    Confirm there is no packet seen with the IP address of 1.1.1.1 destination
    (4) plug the cable between vmnic1 and switch1 gi2/0/4 port ethernet
    (5) wait 60 to 120 seconds
    (6) watch a burst of frames ethernet with the destination MAC address of the VM (which owns 1.1.1.1) in the output of tcpdump

    Unplug physically 2 cable NETWORK card on the host and configuration mirrored port on the switchport to 1 NETWORK adapter of the host, I have been able to confirm that the host VMWare issues guides on NIC1 with a destination MAC address of one of its own VM.

    After carefully reviewing the captured data, I noticed that the destination frames wrong "02:bf:cb:50:a2:76" MAC address actually belonged to "Local Area Connection 1' one of my Windows 2003 Server WHAT VM installed on the suspected host.

    Dig a little deeper, I discovered that this virtual NETWORK card is presented to the operating system as
    Name: Local 1 network connection
    "Type: VMware Accelerated AMD PCNet adapt."
    MAC: 02-BF-CB-50-A2-76

    But the configuration of the virtual machine in vCentre is
    Name: Network adapter 1
    Type: Flexible
    MAC: 00: 0C: 29:fa:e8:83

    Note the different MAC addresses.

    Digging a little further I discovered that Windows 2003 server has configured on "Local 1 network connection" network load balancing and NLB is the cause of the altered MAC address.

    Rather than to investigate further I have just placed a load balancer linux before the server windows 2003 cluster and that you turn off NLB.

    But I suspect that there is still a fundamental problem in the Virtual Switch VMware with how he learns the MAC addresses of the virtual machine is using flexible vNIC. In particular, with a virtual machine that uses a form to override the MAC address such as that used by NLB.

    I would be grateful the help, thanks again.

    Although each ESX Server will require its own port-channel group independently. So you will have at least the same number of channel groups of port you have esx servers.

    There isn't any problem with not not using circuits.  If you are ending in expansion and maybe a different subnet for your virtual machine to access the creation, then channels will be required to spend more than one vlan to the port-channel group.

    Hope that helps!

  • record channel times of order data NI_DataType

    I'm trying to replicate some features of selection of the control Data Logging property in the VeriStand workspace in a Labview application (I wish I could get just the VI for control of the workspace).  In the control of the registration of the properties-> channel category data the time channel can be selected.  When I select absolute time he records the system path = 'targets, controller, channels, Absolute System Time. "  But I have one property TDMS NI_DataType = 68.  If I manually select the channel (add channels) we obtain a = 10 NI_DataType.  The difference seems to be that the NI_DataType = 68 has the well formatted time (m/d/Y/min) while the NI_DataType = 10 at a time in a large number that represents the number of seconds.  The NI_DataType is read-only.  How can I get the formatting nice NI_DataType = 68 to be registered like that?  This post is treated?  If so how to do that?

  • Continuous sampling PlotStripChart DAQmx and multiple channels

    I modified the sample code sychAI DAQmx - AO.cws slightly to provide more output wavforms. I can read at the same time on a single channel without problem.
