start

Start a software process.

Syntax: start shell

telnet

Start a telnet session to another host.

Syntax: telnet host <8bit> <bypass-routing> <inet | inet6> <noresolve> <port port > <interface interface-name> <routing-instance routing-instance-name > <source address > <vpn-interface vpn-interface>

test

Run various diagnostic debugging commands.

Syntax: test (configuration | interface | msdp | policy)

traceroute

Trace the route to a remote host.

Syntax: traceroute host <as-number-lookup> <bypass-routing> <gateway address > <inet | inet6> <noresolve> <routing-instance routing-instance-name><source address > <tos value > <ttl value > <vpn-interface vpn-interface > <wait seconds>
