Note:
1. Combo port is a conception involving the physical layer and the LLC sublayer of the
datalink layer. The status of a combo port will not affect any operation in the MAC 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.
2. If a combo port connects to another combo port, it is recommended for both parties to
use copper-forced or fiber-forced mode.
3. 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 cable port:
Hardware is Gigabit-combo, active is fiber.
Example: Setting ports 1/21-24 to fiber-forced.
Switch(config)#interface ethernet 1/21-24
Switch(Config-Port-Range)#combo-forced-mode sfp-forced
3.1.3 clear counters interface
Command: clear counters interface [{ethernet <interface-list> | vlan <vlan-id> |
port-channel <port-channel-number> | <interface-name> }]
Function: Clears the statistics of the specified port.
Parameters: <interface-list> stands for the Ethernet port number; <vlan-id> stands for
the VLAN interface number; <port-channel-number> for trunk interface number;
<interface-name> for interface name, such as port-channel 1.
Command mode: Admin Mode.
Default: Port statistics are not cleared by default.
Usage Guide: If no port is specified, then statistics of all ports will be cleared.
Example: Clearing the statistics for Ethernet port1/1.
Switch#clear counters interface ethernet 1/1
3.1.4 flow control
Command: flow control
