Option
Subnegotiation
The
VMWARE-TELNET-EXT
telnet option
requires various suboptions to support remote serial port access. The virtual
machine and proxy use subnegotiation to indicate the command sets that they can
support. Subnegotiation identifies all commands for negotiation as well as
commands for proxy support, vMotion notification, and virtual machine
identification. Table 2-2 lists the commands for option subnegotiation.

KNOWN-SUBOPTIONS-1
suboptions
A virtual machine notification that
indicates the
VMWARE-TELNET-EXT
suboptions that it can generate and accept.
suboptions is a sequence
of one or more codes, each of which corresponds to a VMware telnet extension
command.
If the virtual machine sends this
message more than once during a session, the list of suboptions is always the
same. The presence of a command in the list does not imply that the virtual
machine will use the command during the session.
