    Hi,

     

    We had a loop in our network by our furniture contractor loop the cable between two sockets which are in two vlans, how we can mitigate such a condition.

     

    thanks

    Generally storm control can protect against this or else turn on STP on access user ports and use BPDU guard.

    Don't have your furniture contractor perform network maintenance? Smiley Happy

    Thank you for the message, we have MSTP enabled on the switch, Is this enough with BPDU guard ?

    Should be as long as MSTP (or any form of STP) is enabled at the user ports along with BPDU Guard.  For info go here:
