Message_Ver Message version. Because each client application contains one or
more versions of its messages, ISSU needs to discover these versions
and negotiate between the new and old system software which version
to use in its preparatory communications.
Message_Mtu Maximum size (in bytes) of the transmitted message.
A value of 0 means there is no restriction on size; fragmentation and
re
assembly are therefore being handled in a manner transparent to the
ISSU infrastructure.
