12K Port-channel Problem

Hello Everyong,
I'm trying to create a port-channel on my cisco 12K router and getting this error message.
Could some explain to me why this isn't working?
12Kconfig)#interface  GigabitEthernet5/1/0
12K(config-if)#channel-group  2
Error: not supported on  GigabitEthernet5/1/0.
Please and Thank you

Hi,
i found one previous issue with the same error and it was found that LinkBundling on Engine 5
interfaces is supported from 33S release only.
More info:-
http://www.cisco.com/en/US/docs/ios/12_0s/feature/guide/lnkbndl.html#wp1279546
So this feature is supported in 33S.
thanks,
Vinay

  • Port-channel Problem between Fabric Interconnect and N7K vPC

    Dear all,
    I have a problem with Port-channel Uplink between Fabric Interconnect with N7K using vPC
    This is my network topology for UCS Deployment
    In N7K I has configured vPC for red link and green link, at Fabric Interconnect A I has configured Port-Channel with member is Port 1 and Port 2, uplink is red link. At Fabric Interconnect B, I has configured Port-Channel with member is Port 1 and Port 2, uplink is green link.
    The show interface port-channel on N7K is good, every port-channel is up and have all member. But At Fabric Interconnnect, when I see on UCS Manager, the status of Port-Channel on Fabic A and Fabric B is fault with Additional Info: No operational member. Although all link is link up and I has status of Port-Channel is enable on UCS Manager. When I see the Properties of Port 1, Port 2 on Port-channel, I see the membership status is : individual. This mean port-channel is not up and no membership in this configuration. I want to using port-channel for load balance and plus more bandwidth for uplink to 20Gig. I don't understand why ?
    Please help me resolve this problem, I has send the capture screen of UCS Manager when I show status of Port-channel and Port-member in port-channel in attach items.
    Anyone can help me to resolve this, thanks you very much. Please reference attach items for more detail about fault.
    Thanks,
    Trung.

    Thanks Matthew very much,
    I has resolved this problem. The reason of problem is miss match protocol of port-channel between N7K and Fabric Interconnect. The Fabric Interconnect always use LACP protocol, but N7K using Port-channel mode on, that why the port-channel failed. I has configured LACP for port-channel in N7K, it has resolved the problems.
    Thanks,
    Trung.

  • MDS9513 Add ISL to Port Channel problem.

    Hi Experts,
    I have a problem when add a new ISL to an existing Port Channel config.
    The ISL port is up state and correctly configured like another ports in port channel.
    Looks bellow the error:

    Anyone seen this?

    That did the trick - specifically setting the port channel to rate-mode shared.  Certainly solved the problem as far as getting all the deisred ports up in the channel, but where I still have a knowledge gap is the operational difference between dedicated and shared.  Are there any Cisco docs (beyond the command reference guide to toggle the feature) that explains why you'd choose one versus the other, and what it means from a design perspective?
    On a different note, while I'm no expert, here's some background to consider for others who may encounter the same issue (whether on UCS or a Nexus 5K).  I  (and our network team) come from an IOS background, so while the IOS "parts" of NX-OS are pretty familiar, the SAN "parts" of NX-OS are a little new.  We're also more CLI oriented, and while not impossible to configure via CLI, in our environment, the GUI for UCS seems to be more popular across the board - and we're still learning that piece as well.
    Our storage team is very familiar with SAN-OS, so they're very comfortable with the SAN "parts" of NX-OS.  But, they're very used to configuring the MDS switches via the GUI, which is what got us off track a bit.  In our scenario, creating a SAN port channel on the MDS via the GUI didn't give us the option for setting "switchport rate-mode shared"  Not saying it's not there in the GUI, but we certainly couldn't find it.
    Long story short, if the configuration of the SAN port channel on the MDS is in question, check it via the CLI and make any necessary changes there as a quick workaroud.

  • Port-channel problem with WiSM

    Has anybody met following similar problem:
    I put WiSM into slot 3(also tried slot 6) of 6506(sup720-3B, s72033-adventerprisek9_wan-mz.122-33.SXH.bin), using following command to setup the port-channel:
    interface Port-channel1
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk native vlan 5
    switchport trunk allowed vlan 1-1000
    switchport mode trunk
    int range g3/1-4
    switchport
    switchport trunk encapsulation dot1q
    switchport trunk native vlan 5
    switchport trunk allowed vlan 1-1000
    switchport mode trunk
    channel-group 1 mode on
    I can use "session slot 3 pro 1" to login to the WiSM, but can't ping WiSM's management IP address from 6506, then I find the port-channel has problem, only G3/1 is up and included in the channel, G3/2-4 are up but line protocol is down, then I found from the log that: "AESUT: %EC-SP-5-CANNOT_BUNDLE2: Gi3/2 is not compatible with Gi3/1 and will be suspended (qos-card type unavailable for Gi3/2 or Gi3/1)". It says those GE port are not compatible for qos-card type, but I checked the configuration, all GE using the same configuration. Don't know why, maybe a bug? Appreciate for any feedback

    I have the same problem, but it has something to do with QoS. When you disable "mls qos" on the switch, the port-channel will function normal again.
    It doesn't help when you configure "mls qos trust dscp" on the port-channel!!!!!

  • FI 6248 Nexus 5548 Port-channel problem

                       Hi all
    I have a strange behavior between 2 FI and 2 nexus 5k configured as VPC , From a remote location and from my desktop I can ping odd ip and not even , from an other desktop in the same LAN the reverse, for both the tracert are good.
    The only solution is to shutdown  ports 1/1-2 on nexus A or FI A and in that case both desktops can ping both IP.
    All seems OK, no log error , no error on interface , I give below some commands
    What thing to know is that the nexus b has a L3 card , not the Nexus A , In fact I am waiting for a spare L3 daughter card.
    On both NexusI have such configuration and status

    In fact in the probem I described the path is Esx -> FAB A - > N5K-A (for layer 2) -> N5K-B (for L3) -> routing to the LAN
    And what you told me is that such configuration is not supported with VPC configuration , so I need to wait to receive the L3 card for the N5k-A. and check later if I have the same problem.

  • Port-channel L2 problem with Fabric Interconnect and Nexus 7010

    Hi,
    i using port-channel from both fabric interconnect to N7k with 3 cables per Fabric Interconnect.
    but, my problem is when i creating port-channel, Fabric Interconnect don't support mode ON dan rate-mode share in Interface 10G Nexus 7010.
    I was trying :
    1. I using non dedicated port in Nexus 7010.
          - rate-mode share
          - channel-group 1 mode active
          - switchport mode trunk
    when i using this option, the port-channel in Nexus 7010 was suspended
    2. I using non dedicated port in Nexus 7010
         - rate-mode share
         - channel group 1 mode on
         - switchport mode trunk
    when i using this option, the port-channel in Nexus 7010 was came up, but in Fabric interconnect was failed.
    3. I using dedicated port in Nexus 7010
         - rate-mode share
         - channel group 1 mode active
         - switchport mode trunk
    when i using this option, the port-channel in Nexus 7010 was suspended
    4. I using dedicated port in Nexus 7010
         - rate-mode dedicated
         - channel group 1 mode active
         - switchport mode trunk
    when i using this option, the port-channel in Nexus 7010 was came up and running well.
    but, the problem is my costumer do not want using a dedicated rate-mode. if i using dedicated mode the only available port is 8 interfaces instead of 32 ports. i want to using rate-mode share in nexus 7010.
    is there any way to configuring port-channel using mode on in fabric interconnect ? i was trying using CLI to create port-channel in Fabric interconect but i cannot configure the channel group protocol.
    i attach the topology of N7K with Fabric interconnect.
    regards,

    Hi Manish,
    the issue was solved, i was fix it last week.
    the solution is:
    i enable the license grace-priode (since my license is Enterprise so cannot create VDC) then i create a VDC (ex: VDC 2)  so i allocate the interface on all module
    /* Style Definitions */
    table.MsoNormalTable

    N7K-M132XP-12 to VDC 2. after that i delete VDC 2 then all interface back to VDC 1 (default vdc). then i enable the rate-mode share in dedicated port and bundle into port-channel and its working.
    i dont know why it must move to VDC first then it will working, maybe cisco can explain the reasons.
    So here the result of my port-channel :

  • How to configure a port channel with VLAN trunking (and make it work..)

    We're trying to configure a port channel group with trunked ports to connect a NetApp HA pair. We want to create two data LIFs and connect them to the switch stack.  We are trying to create 2 data lifs, one for cifs and one for nfs that are on different vlans.
    We want the same ports to be able to allow multiple vlans to communicate. (trunked)
    These data lifs should be able to fail over to different nodes in the HA pair and still be able to communicate on the network.
    What this means is that we have to connect 4 ports each for each node in the NetApp HA Pair to the switches and create a port channel of some type that allows for trunked vlans. When we configure the ports, the configuration is as follows (below):
    We are only able to configure an IP on one of the vlans.
    When we configure an IP from another vlan for the data lif, it does not respond to a ping.
    Does anyone have any idea what I'm doing wrong on the Cisco switch?

  • Dlsw using port channel

    I have 2 dlsw router at head quater office, named dlswA and dlswB.
    From branches router, dlswA is a primary peer and dlswB is a backup peer.
    Both dlswA and B have 2 fast ethernet interfaces.
    The current configuration of dlswA and dlswB are 1 port as IP port and other port as sna/bridge port.
    With this configuration the problem is when SNA port at dlswA problem, then dlsw circuit will have the problem, because dlsw peer from branches still connected to dlswA.
    if I configure 2 fast ethernet port become a port channel. And configure IP and bridge group at port channel interface (IP and SNA at the same interfaces), so when the port channel is down, then branches will connect to dlswB as a backup peer
    Are the port channel configuration will solve the problem ? How about the stability of this configuration?

    Thank Matthias for your reply.
    Both of head end routers are on the same vlan and the host is using same mac address.
    As far as i know if from branch have 2 active peer with cost setup, there will loops posibility because both head end routers are using ethernet with same vlan and same host mac address.
    I test the port channel within my LAB using netbios, seem works as expected. when single port at port channel down, branch circuit still remain at dlswA router, when all port channel member down, the branch peering move to dlswB.
    Here are the config:

  • Design help related to ACE to Switch connectivity using Port-Channel

    Hi,
    I have a Cisco ACE 4710 configured in One-Arm mode. This ACE is getting connected with 2 3750 switches. These 2 3750 switches connected in trunk mode.

    The problem is that 3750 switches are not stacked.
    Application is working fine. But i am getting a lot of MAC flapping messages..
    kindly suggest whether this design is OK or something needs to be done to rectify it...
    Attached a small diagram..

    Hello acharyr123,
    I don't think this design is ok, and it would cause mac flapping since the two indepedendent 3750 switches will learn the ace mac addresses off of two different interfaces.  The 3750s would have to be stacked so that they would act as one switch then this should work correctly.
    Thanks

  • Interfaces in port-channel keep err-disabling because of keepalives

    Below is the current portchannel that I am having problems with.  The interfaces on Switch A keep going into an error disabled state because they receive their own loopback.  Cisco says to disable keepalives and that it will fix the problem, but I do not like the idea of disabling keepalives.  Has anyone found a solution other than disabling keepalives?  Notice that ios's are different, but am not convinced that this is the issue.  Also one is PoE and the other isn't.  Lastly, i found this article "Keepalives are sent on all interfaces by default in Cisco IOS Software Release 12.1EA-based software. In Cisco IOS Software Release 12.2SE-based software and later, keepalives are not sent by default on fiber and uplink interfaces".  I would think trunked interfaces in a port-channel would be uplink interfaces and if this is true, it should be sending out keepalives anyway since i am running the 12.2SE based ios.  Thanks for whatever input you may have.

    PER CISCO
    Symptom:
    An interface on a Catalyst switch is errordisabled after detecting a loopback.
    Mar 7 03:20:40: %ETHCNTR-3-LOOP_BACK_DETECTED: Loop-back detected on
    GigabitEthernet0/2. The port is forced to linkdown.
    Mar 7 03:20:42: %LINK-5-CHANGED: Interface GigabitEthernet0/2, changed state
    to administratively down
    Mar 7 03:20:43: %LINEPROTO-5-UPDOWN: Line protocol on Interface
    GigabitEthernet0/2, changed state to down
    Conditions:
    This might be seen on a Catalyst 2940, 2950, 2950-LRE, 2955, 2970, 3550, 3560
    or 3750 switch running 12.1EA or 12.2SE based code.
    Workaround:
    Disable keepalives by using the no keepalive interface command. This
    will prevent the port from being errdisabled, but it does not resolve the root
    cause of the problem. Please see section below for more information.
    Additional Information:
    The problem occurs because the keepalive packet is looped back to the port that
    sent the keepalive. There is a loop in the network. Although disabling the
    keepalive will prevent the interface from being errdisabled, it will not remove
    the loop.
    The problem is aggravated if there are a large number of Topology Change
    Notifications on the network. When a switch receives a BPDU with the Topology
    Change bit set, the switch will fast age the MAC Address table. When this
    happens, the number of flooded packets increases because the MAC Address table
    is empty.

  • Nexus 1000v - port-channel "refresh"

    Hi All,
    My question is, does anyone have any information on this 1000v command:
    Nexus-1000v(config)# port-channel internal device-id table refresh
    I am looking for a way for the port-channel interface to be automatically removed from the 1000v once the VEM has been deleted, currently the port-channel interface does not disappear when the VEM has been removed. This seems to be causing problems once the same VEM is re-added later on. Ports are getting sent into quarantine states and ending up in invalid states (eg. NoPortProfile state when there is actually a port-profile attached).
    Anyway, if anyone can explain the above command or tell me how to find out more, it would be great, I can't find it documented anywhere and the context-sensitive help in the NXOS is vague at best.

    Brendan,
    I don't have much information on that command, but I do know it wont remove any unused port channels.  They have to be manually deleted if they're no longer needed.
    The port Channel ID will remain even after a VEM is removed in case the assigned VEM comes back.  When a VEM is decommisioned permanently, I'll do a "no vem x" to also remove the Host entry for that VEM from the VSM.  This way the module slot # can be re-assigned to the next new VEM inserted.  After adding/removing VEMs just do a "show port-channel summary" to see any unused Port Channel IDs, and delete them.  It's a quick & painless task.
    I would hope this wouldn't be a common issue - how often are you deleting/removing VEMs?
    Regards,
    Robert

  • Create port channel between UCS-FI and MDS 9124 (F Mode)

    Dear Team,
    We were trying to create  port channel between UCS FI and MDS 9124
    But the port channel not getting active in F mode on MDS 9124
    FI is in FC End Host Mode
    We have enabled FC uplink trunking on FI
    We have enabled NPIV on MDS
    We have enabled trunk on MDS
    FI and MDS in default VSAN
    To check we changed the FI mode to FC Switching mode and port channels became active but in E mode
    when we enabled FC uplink trunking on FI and FC Switching mode port channels became active in TE mode
    but in both the above cases showflogi database shows WWPN of SAN alone not showing any from FI.
    How to achive this?
    Have read that no need to change the swicthing mode to FC Switching mode and keep as FC Endhost mode
    SO how to achieve Port channel with F mode in MDS and FI ( Mode showing as NProxy)
    Does it has to do anything with MDS NX-OS version? (https://supportforums.cisco.com/thread/2179129)
    If yes how to upgrade as license for ports came along with Device and we do not have any PAC/PAK or license file as it came
    with license
    Also we have seen 2 files availabe for download (m9100-s2ek9-kickstart-mz.5.2.8b.bin and m9100-s2ek9-mz.5.2.8b.bin) which to use
    Thanks and Regards

    Hi Jo Bo,
    what version of software if your MDS running?
    On your UCS do connect nxos and show inteface brieft and look at the mac address.
    it is possible that you might be hitting the bug below. if this is the case you might need to upgrade the firmware on your MDS.
    Add MAC OUI "002a6a", "8c604f", "00defb" for 5k/UCS-FI

  • ACE - Port-channel High Availability

    We have configured two ACEs with high Availability. ACEs link with our cores, switches cat6500, through a port-channel, ACE’s ports G1/1 and G1/2. High availability works fine if some vlan down but it doesn’t work if an interface down, only if both interfaces get down because then, all vlans of the channel port get down two.
    If possible get an interface port-channel high availability?
    Thanks for your help in advance.

    Thanks for your answer. I have two Cat6500, no VSS possibility. I have two ACEs so each one has configured a port-channel with one Cat6500 (two ports). It works fine. Any problem with that. My issue is when one port-channel of both port is down, failover doesn’t works then, only if both ports are down or vlans are down. I think high availability is only possible in vlan interfaces, not in physical interfaces.
    Regards my friend.

    does it mean that looping has occured yesterday?
    i use command below do not have yesterday record
    show spanning-tree internal event-history tree 1 brief | in "2015:03:15 10"
    first core is root switch
    now port channel shutdown in first core and use port channel in second core. How can i see which problem has occurred in port channel ?
    how to know which port has problem ?
    how to know which vlan caused the problem ?
    we notice one of access switch has lost config, will it affect the distribution layer switch?
    i remember that yesterday i just get log with filezilla after configure notebook same vlan and same network with the testing access switch

    Not sure if youre after the portchannel bandwidth or port-channel speed... If you really want to get an insight on the bandwidth usage, get SNMP on both sides, actively monitor the port channel and interfaces (real time by frequent polling)
    And you could get two endpoints @ 10 gb nics that are bundled, then 'thrash' the link, end to end. I use iperf, you could use big ftp transfers to test and see what performance is. You'll get the rate / speed in which the links are operating 'end to end'
    It may mean that the ports are @10gb full duplex, but the overall bandwidth is 20gb
