In certain interoperability situations, it is necessary to turn autonegotiation off on a
Gigabit Ethernet port. Even though a Gigabit Ethernet port runs only at full duplex and
gigabit speeds, the command that turns off autonegotiation must still include the
duplex setting.
The following example turns autonegotiation off for port 4 (a Gigabit Ethernet port):
config ports 4 auto off duplex full

Tab le 5-1 describes the Summit switch port commands.
Table 5- 1: Summit Switch Port Commands
Command Description
config jumbo-frame size <jumbo_frame_mtu> Configures the jumbo frame size. The range is
between 1523 and 9216. The default setting is
9216.
config ports <portlist> auto off {speed [10 |
100 | 1000]} duplex [half | full]
Changes the configuration of a group of ports.
Specify the following:
■
auto off — The port will not autonegotiate
the settings.
■
speed — The speed of the port (for 10/100
Mbps or 100/1000 Mbps ports only).
■
duplex — The duplex setting (half- or
full-duplex).
config ports <portlist> auto on Enables autonegotiation for the particular port
type; 802.3u for 10/100 Mbps ports or 802.3z for
Gigabit Ethernet ports.
config ports <portlist> display-string <string> Configures a user-defined string for a port. The
string is displayed in certain show commands (for
example, show port all info). The string
can be up to 16 characters.
config ports <portlist> qosprofile <qosname> Configures one or more ports to use a particular
QoS profile.
disable jumbo-frame ports [<portlist> | all] Disables jumbo frame support on a port.
