I have an extreme x440-24t-10G that is connected to an x670 both running EXOS 18.104.22.168. The x670 is, in turn connected to a Cisco ASR 9010 that implements an MPLS circuit to a customer on the other side of the network. The end customer has requested a hard loop test and I am unsure is the x440 will take issue with a hard fiber loop being placed on the same port. Is there a method to allow the customer to conduct throughput testing with a soft-loop on the x440 to avoid dealing with STP issues? Or is there a better option available?
Rough design of the network layout in question.
the vlan for the customer is setup as a VMAN using tag 2716 on the x440, once the trunk hits the ASR9K, it is MPLS switched to the destination router and handed off to the customer.
Any insight on a method to conduct this testing would be most appreciated.
