This object provides the ability to enable or
disable early token release for a particular port.
Early token release only applies to ports
operating at 16 Mbps. If ifSpeed reflects 4 Mbps
for a particular port, then the corresponding
instance of this object will have a value of
disabled(2) regardless of attempts to set the
object to enabled(1).
Whenever a port is opened with a ring speed of
16 Mbps, by default, early token release will be
enabled.
