Service Manual

• Up-MEP — monitors the forwarding path internal to a bridge on the customer or provider edge. On
Dell Networking systems, the internal forwarding path is effectively the switch fabric and forwarding
engine.
• Down-MEP — monitors the forwarding path external another bridge.
Configure Up- MEPs on ingress ports, ports that send traffic towards the bridge relay. Configure Down-
MEPs on egress ports, ports that send traffic away from the bridge relay.
1. Create an MEP.

Creating a Maintenance Intermediate Point
Maintenance intermediate point (MIP) is a logical entity configured at a port of a switch that constitutes
intermediate points of a maintenance entity (ME).
An ME is a point-to-point relationship between two MEPs within a single domain. An MIP is not
associated with any MA or service instance, and it belongs to the entire MD.
