Maintenance End Points; Implementation Information - Dell S4048–ON Configuration Manual

Figure 4. 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.

Implementation Information

The S-Series has a single MAC address for all physical/LAG interfaces and hence only one MEP is allowed per MA (per VLAN or per
MD level).
