Trying to get rid of a trunk's member port config

  • 1.  Trying to get rid of a trunk's member port config

    Posted Feb 10, 2021 10:50 AM
    trunk 47-48 trk1 lacp
    interface 47
    rate-limit icmp ipv4 percent 10
    rate-limit bcast in percent 30
    exit
    interface 48
    rate-limit icmp ipv4 percent 10
    rate-limit bcast in percent 30
    exit

    I wanted to get rid of the rate-limit on interfaces 47 and 48 but can't undo them as they're member of a trunk.

    ARSWKAL173(eth-48)# no rate-limit bcast in
    48: Operation is not allowed for a trunked port.

    As the trunk is my uplink...  difficult to trash the trunk config.

    So i thought of trying to download the config file, edit it (remove rate-limit), and upload again.  Set as startup-config and reboot.
    I can upload a new config using http or tftp.  But whenever i look at the contents of that new config, the rate-limit is again configured on those trunk's interfaces. 

    ARSWKAL173(eth-48)# show version

    Anyone having an idea to fix this, besides attaching a serial connection, remove the trunk etc...

    Hi Peter, 

    I did a quick validation in my lab on this:

    First configured the two ports with your rate limit values and added them to a trunk.


    Then, I copied off the config and hand edited it, removing the interface configuration from the config, saved it, and reuploaded to switch, which it then rebooted.

    After rebooting, the trunk was still configured without the rate limit configuration.

    I will work with engineering to get this fixed, as it should be able to be removed from the trunk config, or to not be able to configure the trunk with the rate limit setting existing on the interface.

    Have you taken a look at this? Replace the config without a reboot. Might want a connection to the device in case you lose connectivity via SSH :)

    See the attached guide.

    @Dustin, 

    the command cfg-backup does not exist on my switch.

    I found out that there is a difference in showing the contents of a config file using the http gui and using the 'show config' cli.  The cli output is actually correct.  While the output using http is not.

    I can continue by cli and reboot the switch.

    @Justin : thx!​​

    Hi,

    Dumb question but, have you considered simply removing the port from the trunk, fixing whatever you want from that port and then readd it to the trunk?

    Since it's a LACP trunk you will still be able to access the switch through the second link at the first one will become LACP blocked. If you want to not lose any traffic just shutdown the port before doing it, that way there will be no traffic disruption whatsoever.


    Best regards,

    Aarón

    Hi Aarón, that's an excellent suggestion and i'm not sure why i did not think of that :-)  I'm pretty sure this would have worked...  Meantime, i fixed it by creating a new config file and rebooting...
