Nexus 5595 7.0(5)N1(1) - Config Sync / CFS Issue

Hello,
Posting this fix as it may help anyone facing the same issue.
We recently installed 2 x Nexus 5596 into our DC with the management connections running across 6500 VSS switches.  We have the same setup in another DC and all worked fine.  However, with the new installation we upgraded to 7.0(5)N1(1) and hit a problem with the config-sync not working across the mgmt0 interfaces.  However, the Peer was reachable over mgmt0 as VPc was up and we could ping / SSH no problem.
We also have the necessary ‘cfs ipv4 distribute’ enabled.  Output of issue below:
switch-profile  : Tcprofile
Peer-IP-address            : 192.168.1.28
Peer-sync-status           : Not yet merged
Merge Flags: pending_merge:1 rcv_merge:0 pending_validate:0
Peer-status                : Peer not reachable
We tried various things such as removing the ‘cfs ipv4 distribute’ and re-enabling but this didn't fix the problem.  So spoke to a Cisco engineer who suggested the 6500 could be blocking multicast and therefore stoppping CFS traffic across our management Vlan.  Apparently there have been some changes to CFS in the latest NXOS.
So the fix was simple in the end.  We just enabled PIM on our 6500 SVI and Config Sync sprang into life.  See below:

Hope this helps

Hi, I have upgraded from 5.2.1.N1.4 to 7.1.0.N1.1b.
There were many bugs.
I found we can't upgraded to 7.1.0 from NX-OS prior to 7.0 in Cisco official.
So, I have upgraded to 7.0.5N1.1 then to 7.1.0N1.1b.
In result, some part of startup-config such as logging server  is lost.
I'm going to try to upgrade in same process a few times.

  • Config-sync on Nexus 7k?

    I'm using configuration synchronization on my Nexus 5k pair.  But I've got a couple of Nexus 7k switches on the horizon.
    But I can't seem to find anything about config-sync being supported on the 7k platform.  Is anyone using config-sync on the Nexus 7k platform??
    Thanks.

    I don't think this is a supported feature on the Nexus 7000's.

  • Nexus 5K Config-Sync : Things to look out for

    I've looked through the Cisco config guides for setting up Config sync and have successfully used it to configure dual-homed FEX's ports.
    Is there anything I should be aware of that can cause issues?
    I enabled config sync on an existing pair of 5Ks.  In other words, the 5Ks already have existing configurations on them before I enabled config sync.

    Hi,
    According to the this link, you still have to configure the single port in switch profile. Config sync is used when your devices are connected to both 5ks, so you don't have configure the same thing twice.  If your device is going to be singly attached, there is no need for config sync.
    Guidelines and Limitations
    The guidelines for configuration synchronization are as follows:
    •You must configure the following interfaces in a switch profile:
    –Port-channel interfaces
    –Ports that are not channel-group members
    •You must configure all port-channel members outside the switch profile in configuration terminal mode.
    •You must follow configurations in a specified order.
    •Depending on the type of vPC topology (active/active or straight-through) and the type of configuration that is needed (port channel, nonport channel, FEX, QoS, and so on), you must use the switch profile mode or the configuration terminal mode. See the "At-A-Glance Configuration Modes" section to identify what mode is used for different types of configurations.
    Configuration synchronization has the following configuration limitations:
    •FCoE in vPC Topologies—FCoE configurations are not supported in switch profiles because configurations are typically different on peer switches. If you enable FCoE on a vPC peer switch, you must not configure the port channel in the switch profile.
    • Feature Commands—The feature feature name commands that enable a conditional feature are not supported in switch profiles. You should independently configure these commands on each peer switch in configuration terminal mode.
    •Configuration Rollback and Conditional Features—With configuration synchronization, when a conditional feature is present in a checkpoint and not in the running configuration, a configuration rollback to that checkpoint fails. The workaround is to reconfigure the conditional feature ("feature xyz") before the configuration rollback is executed. This workaround also applies to the vpc domain command and the peer-keepalive command in vpc-domain mode.

  • Nexus 5548 acl in config sync

    Hello,  I have a following problem. When configuring ip acl in config-sync mode I get following message: "Error: Cannot configure acl rule without seq no."  Is this a bug or a feature? I'm running  5.1(3)N1(1)

    sounds more like a bug. i see a bug being filed on it internally (not customer viewable yet). CSCtz27923. I will make it customer viewable shortly.

  • Config-sync issue in Nexus5K

    Hello
    I am trying to add a vlan to my pair of Nexus 5K with the confi-sync, but I recieve a really strange error comming from the peer switch
    switch-profile  : S1-S2
    Peer-IP-address            : x.x.x.2
    Peer-sync-status           : In sync
    Peer-status                : Commit Failure

    Does anybody know what does it mean ?
    Thank you in advance

    My guess is that on the other Nexus switch the username/password/privilege information is different. Check out this document that has a lot of details on config-sync and the ways it can go wrong...

  • Is anyone else having Config error 16 issue when trying to start PSE 12 or Premier Elements after Mac upgrade to Yosemite 10.10 on iMac

    Is anyone else having Config error 16 issue when trying to start PSE 12 or Premier Elements 12 after the Mac upgrade to OS X Yosemite 10.10 on iMac. I have had a number of issues with software and things after upgrading to OS X Yosemite 10.10 and even 10.10.1.  I have uninstalled and reinstalled both PSE 12 and Premier Elements 12 a number of times and everything goes fine until its ready to launch and then you get an error message. Numerous uninstalled and reinstalls don't removing the problem.  Strangely enough  PSE 11 still appears to boot up and I never owned Premier Elements 11 so I don't know if it will start. I thought with Apple dropping its Apeture software and greater integration of iPhoto and Apeture files into Lightroom 5.7 all would be harmonious between these two players. Im not sure where Adobe wants us to go it recently removed the plugin to allow you to update files from LR to Adobe Revel, whats up with that. I now own two version of Adobe software that no longer work with my Mac and now way of uploading pictures from Lightroom to Revel. Needless to say I am pretty reluctant to sign on to a subscription of Creative Cloud with long term financial obligations when I can't even get my current Adobe software to work independently much less integrate with Lightroom. Frustrated with it all!

    Get rid of 'put disks to sleep when possible' and you may see a dramatic improvement (not necessarily a cure).
    That specific problem is a multiple-Processor (including graphics processor) problem, where one of the processors lost track of whether it should be responding to interrupts. You may have a Hardware problem.

  • ACE Switchover and Config Sync

    Hi
    I'm new to the ACE modul and trying to set up some szenarios and i run already into some troubles.
    Question 1)
    I configured redundancy to another module - virtulised mode. Config sync between the context worked fine. If i change s'thing in the activ context it was copied to the standby context. But if i changed something in the active Admin context it was not copied to the standby Admin context.
    Question 2)
    FT Switchover in the Admin context is not possible returns the following fault:
    ACE_Switch08/Admin# ft switchover
    This command will cause card to switchover (yes/no)? [no] yes
    Invalid FT group. FT switchover command will be ignored.
    ACE_Switch08/Admin#
    If I switch a single FT group it works. But how is it possible to switch all FT groups a the same time? Do i have to switch each context by itself?
    Question 3)
    After i have switched the active context to the standby context, the ft group x command shows both peers as active. After i take the standby ft group no inservice and back inservice it shows correctly Active and standby_HOT.
    The configuration:
    hostname ACE_Switch08

    Hi Pat,
    1)
    for my config i just put the "user" or "backend" contexts into ft groups. I don't sync the admin contexts on both aces. I am not even sure if that makes sense or is "best practicse".
    So if you don't put the admin context into an extra ft group it won't be synced. you have to configure the admin contexts on each physical ace separately.
    Putting the contexts sf0-2200 & sf0-2220 into an ft group and not having an ft group for admin is the way to go IMHO.
    2)
    If you do a switchover you always have to specify which context you want to switchover. I don't think that you can actually switchover a whole bunch of contexts with this command. If you want to do that a reload is the only way AFAIK.
    Try:
    ft switchover 1
    ft switchover 2
    3)
    This could be because you have not configured the other ACE's admin context to participate in the ft properly.
    My configs looke like this.

  • Problem with config sync between two CSM-S modules

    Hi everybody,
    I have a problem with config sync between two CSM-S modules.
    I am using CSM-S software version 2.1(8).
    The acitve module is used in a 6509 with WS-SUP720-BASE supervisor running software version 12.2(18)SXF12a.
    The standby module is used in a 6509-V with VS-S720-10G supervisor (no VSS setup) running software version 12.2(33)SXI3.
    Failover seems to work fine:
    switch-active#sh modu csm 2 ft                                      
    FT group 1, vlan 398
    This box is active
    Configuration is out-of-sync
    priority 150, heartbeat 3, failover 40, preemption is on
    switch-standby# sh modu csm 2 ft
    FT group 1, vlan 398
    This box is in standby state
    Configuration is out-of-sync

    Hi Christoph,
    I am running into the exact same issue. Upon further investigation I've discovered that this is a known bug, CSCtd09117.  You can read more about it here: http://tools.cisco.com/Support/BugToolKit/search/getBugDetails.do?method=fetchBugDetails&bugId=CSCtd09117 .   Apparently this is fixed in ver 12.2(32.8.11)SX323 .
    I haven't had a chance to upgrade yet, so I can't verify the fix, but if it works for you please let me know.
    Regards,

  • CSM config-sync in bridge mode?

    We are planning to upgrade our CSM from 4.1.6 to 4.2.6 and wanted to be able to utilize the config-sync capabilites in the new code. First, is config-sync supported in bridge mode and has anyone had much success or problems? We weren't able to find documentation on this? Please help!

    config-sync works with bridge mode and routing mode.
    You might want to go to 4.2.7 due to this ddts :

  • CSM-S SSL daughtercard config sync

    Hi there,
    First Question
    Is it possible to do a config sync for the CMS-S SSL daughtercard ?? On the SSL daughtercard of the standby CSM is no config _
    Second Question
    How can we built up an redundent configuration (FT) with the CSM-S SSL daughtercard ??
    In our actual configuration the CSM works in active - standby mode.
    Thanks a lot
    Dirk Barnekow

    No, you cannot config sync for the CMS-S SSL daughtercard

  • 5548 Config Sync issue - Suspended by vPC

    I have 2 UCS 6120 fabric interconnects which both have VPCs to 2 x 5548s.  First fabric interconnect uses Po260 & vPC 260 and second fabric interconnect uses Po261 & vPC 261.  I used config sync to add "spanning-tree port type edge trunk" to int po 260 & 261.  The commit worked properly, peers are in sync, etc.  The problem is when I committed the command, int po 260 & 261 on the secondary 5548 went into "suspended by vPC".  I can't figure out why they did this, the configurations are the same and all vPC consistency checks pass.  To fix the issue, all I had to do was bounce the port-channel on the secondary 5548 (shut/no shut) after which it came back online.  I only did this to Po260 so Po261 is still down so that I can troubleshoot further.  Please see below:

  • CSS11501 Hangs during Config Sync

    We have CSS11501 boxes in redundancy mode. Until now, the config sync process happened without any issues. For the last two occassions, the CSS hangs completely during manually initiated config sync thereby bringing down all active connections..After the sync is completed, the box returns back to normal.
    The only changes made in recent time is the Redundancy config (failover from master to backup forcefully)..
    Any know issues on the following bundle:-
    Version: sg0810002 (08.10.0.02)
    Flash (Locked): 07.40.0.04
    Flash (Operational): 08.10.0.02
    Type: PRIMARY
    Licensed Cmd Set(s): Standard Feature Set

    Hi, I will check to see if your are hitting any know issue but let me tell you that 8.10.002 is the first release of 8.10 code and we have 8.10.301 already which would be the best way to go at this point.
    I will update you with any know issue. It would be useful to see the showtechs when the issue is showing u.
    Also when you say that hangs completely:
    would no respond to ping to the VLAN IP?
    is it accesible via telnet or ssh?
    is it accesible via console?
    What kind of redundancy are you using? do you see any failover at the time of the problem?
    Can you show me the syntax you are using to sync the config?.

  • 7940 Config and flash issues

    Hi, i'm hoping somebody can please help me.
    I have been using VOIP via a softphone for a couple of years now, I decided that I wanted to have a go at setting up a Cisco phone. So I have got a 7940G second hand which works fine. I am a home user trying to learn so I am using a BT Homehub with dynamic IP and SIP on voip-talk.org
    The phone was still configured form the previous owner with subnet, DNS, FTP, VLAN etc. I couldn't find a how to edit these settings, so I thought if I set it back to factory defaults, told it to delete network cfg. I thought on restarting it might ask me to input the detail? but it showing "configuring VLAN" and then constantly stays on "configuring IP"
    although it stills picks up an IP via DHCP and I can ping it ok, I can also browse on to the web interface which show the following info

    Basically I need to know first all how to at least change the settings, as I don't have access via the phone itself or the web interface. And I will probibly also need to reflash the firmware with something that will do SIP.
    Thanks for looking and your help

    Hi
    I think the main issue you have with this phone is that its not picking up a TFTP server IP address and therefore cannot download any configuration details.
    As a start i'd check that the IP address range that it has got via DHCP has an option 150 setup to your CUCM TFTP server.
    Once its got this, if you have auto registration setup if should at least boot up
    Hope this helps
