VoIP phone causing Loop - Disable port with Duplicate MAC Address

[Bill_Handler]

Customer has VoIP Phones. Users will plug both ports into wall jacks causing a loop. Looking for solution

[Paul_Russo]

Hello Bill

Can you please tell me what switch you are using? If it is one that runs XOS as the operating system then you can use a feature called ELRP. It works similar to STP but it is not as configuration detailed. It is essentially two commands.

If it is EOS based or if there is a mixture then STP is a better fit.

Let us know
Thanks

Configure STP on the edge ports with BPDUSafeguard enabled.
