3Com also uses the Internet defined protocol, ARP (Address Resolution
Protocol). This protocol is used in a similar fashion to the tag resolution
protocol, except that it is used to resolve an IP address to a network
address.
RCP, or the 3Com remote character protocol is used to support the re mote
login session. The protocol defines a master/slave relationship between the
device initiating the login session an d the device supporting the session.
Terminal characters are separately sent between the master and slave.
Upon command completion, the slave sends t he output of the executed
command.
RCP also maintains an underlying protocol to determine if the login session
is still active. Basically, the master pings the slave once a minute. After the
timeout period passes without a successful ping, the remote session is
aborted.
