Novel tools and techniques that enable remote network monitoring, and in particular cases, remote monitoring of traffic on a L2VPN. In a particular aspect, tools enable a vendor-independent remote monitoring capability by allowing a port on to be spanned (mirrored) to a virtual local area network attachment circuit at two different provider edge devices. Such embodiments can allow test equipment located at one provider edge device to perform monitoring at another provider edge device without regard to conflicting monitoring protocols, interfaces, and/or the like. |

1. A method of monitoring Layer 2 traffic on a virtual private network (“L2VPN”), the method comprising:
providing a subscriber pseudo wire over a first packet switched network tunnel between a first subscriber attachment circuit at a first provider edge device and a second subscriber attachment circuit at a second provider edge device, the subscriber pseudo wire traversing a L2VPN between the first provider edge device and the second provider edge device and providing communication to transmit subscriber traffic between the first subscriber attachment circuit and the second subscriber attachment circuit; creating a monitoring pseudo wire, over a second packet switched network tunnel, between a first monitoring attachment circuit at the first provider edge device and a second monitoring attachment circuit at the second provider edge device, the monitoring pseudo wire being separate from the subscriber pseudo wire; providing communication, over the monitoring pseudo wire, between the first provider edge device and test equipment coupled, via the second monitoring attachment circuit, with a monitoring port of the second provider edge device; and monitoring, with the test equipment coupled with the monitoring port of the second provider edge device, traffic ingressing and egressing the first subscriber attachment circuit. |
