The info menu items INFO=> SHOW MCPPP LINKS and INFO=> SHOW MCPPP NEIGHBORS provide information
about the PPP connections and the other RASs forming the circuit. The tool DEBUG=> MESSAGE TRACE=>
MCPPP may be useful in discovering MCPPP problems. Another tool exists which must be used in the RAS
containing the primary link for a given PPP connection. The menu option ADMIN=> KILL VIRTUAL SESSION will
show all active secondary links. Selecting one of them will cause the master RAS to send a message to the slave
RAS holding that secondary link, ordering it to drop its connection.
