The speed configuration for a port. The values are:
none(0)..........link down or no traffic.
sAutoSense(1)....Auto-sensing 10 or 100Mbits.
s10M(2)..........10Mbits per second.
s100M(3).........100Mbits per second.
s1G(4)...........1Gbits per second.
s45M(5)..........45Mbits per second (T3) (for expansion board only).
s155M(6).........155Mbits per second (ATM) (for expansion board only).
s10G(7)..........10Gbits per second.
The read-back hardware status are the following:
none(0)..........link down or no traffic.
s10M(2)..........10Mbits per second.
s100M(3).........100Mbits per second.
s1G(4)...........1Gbits per second.
s45M(5)..........45Mbits per second (T3) (for expansion board only).
s155M(6).........155Mbits per second (ATM) (for expansion board only).
s10G(7)..........10Gbits per second.
The port media type (expansion or regular)
and port link type (trunk or feeder) determine
whether this object can be written and the valid
values.
It is not allowed to change speed for trunks ports.
For expansion ports, all of the above speed
can be set.
However, the value of this parameter may be
automatically set whenever the expansion port
is connected (e.g. cascade connecting device).
