Dell S4820T - Maintenance End Points

Figure 3. Maintenance Points
Maintenance End Points
A maintenance end point (MEP) is a logical entity that marks the end point of a domain.
There are two types of MEPs defined in 802.1ag for an 802.1 bridge:
• 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.
