sublayer of the datalink layer and upper layers. If the bandwidth limit for a combo port

is 1Mbps, then this 1Mbps applies to the active port of this combo port, regardless of

the port type being copper or fiber.

 If a combo port connects to another combo port, it is recommended for both parties to

use the forced copper or the forced fiber mode.

 Run show interface under Admin Mode to check for the active port of a combo port

.The following result indicates if the active port for a combo port is the fiber (or copper)

cable port: Hardware is Gigabit-combo, active is fiber (or copper)

 Example: Setting ports 1/0/21-24 to the forced fiber mode.

 Switch(config)#interface ethernet 1/0/21-24

 Switch(Config-Port-Range)#media-type fiber

1.1.8 negotiation

 Command: negotiation {on | off}

 Function: Enables/Disables the auto-negotiation function of a 1000Base-FX port.

 Parameters: on: enables the auto-negotiation; off: disable the auto-negotiation.

 Command mode: Port configuration Mode.

 Default: Auto-negotiation is enabled by default.

 Usage Guide: This command applies to 1000Base-FX interface only. The negotiation

command is not available for 1000Base-TX or 100Base-TX interface. For combo port,

this command applies to the 1000Base-FX port only but has no effect on the 1000Base-

TX port. To change the negotiation mode, speed and duplex mode of 1000Base-TX port,

use speed-duplex command instead.

 Example: Port 1 of Switch1 is connected to port 1 of Switch2, the following will disable

the negotiation for both ports.

 Switch1(config)#interface ethernet1/0/1

 Switch1(Config-If-Ethernet1/0/1)#negotiation off

 Switch2(config)#interface ethernet1/0/1

 Switch2(Config-If-Ethernet1/0/1)#negotiation off

1.1.9 port-rate-statistics interval

 Command: port-rate-statistics interval <interval-value>

 Function: Set the interval of port-rate-statistics, ranging from 5 to 600.

 Parameter: interval-value: The interval of port-rate-statistics, unit is second, ranging

from 5 to 600 with the configuration step of 5.

 Default: Only port-rate-statistics of 5 seconds and 5 minutes are displayed.

 Command Mode: Global Mode

 Usage Guide: None.

 Example: Count the interval of port-rate-statistics as 20 seconds.

 Switch(config)#port-rate-statistics interval 20
