You can also use the xconnect logging redundancy global configuration command to track the status
of the xconnect redundancy group. The command generates messages during switchover events.
This example shows pseudowire redundancy.

Support for H-VPLS

The Metro 3800X and Metro 3600X switches support hierarchical VPLS (H-VPLS).
Note This feature requires the ME 3800X Metro Aggregation Access or ME 3800S Scaled Metro Aggregation
Access software license.
H-VPLS uses spoke connections, usually between Layer 2 switches acting as the CE and PE devices at
the service provider's point-of presence (POP). The spoke connections can be either an IEEE 802.1Q
tagged connection or an MPLS LSP.

and PE2) configured as neighbors on different sides of an MPLS network. Each switch has multiple
customer Ethernet switches connected to it and is connected to a PE device at the service-provider POP.
With no direct connections, H-VPLS allows the customer switches from PE1 to connect to customer
switches connected to PE2.
