Configuring the Layer 2 Tunnel Daemon

To configure the Layer 2 tunnel daemon, do the following:
IMPORTANT!
Make sure there are no traffic loops possible between the substation LAN and other LANs that could
forward GOOSE frames to the LAN. Do not employ a GOOSE gateway between substations that are
already connected. The GOOSE daemon issues packets to the network with a built in Time-To-Live
(TTL) count that is decremented with each transmission. This prevents an infinite loop of packets, but
will not prevent excessive network utilization.
1. Make sure the CLI is in Configuration mode.
