combo enable
Use combo enable to activate the copper or fiber combo port.
Syntax
combo enable { copper | fiber }
Default
The copper combo port is activated.
Views
Ethernet interface view
Predefined user roles
network-admin
Parameters
copper: Activates the copper combo port. In this case, use twisted pairs to connect the port.
fiber: Activates the fiber combo port. In this case, use optical fibers to connect the port.
Usage guidelines
A combo interface is a logical interface that physically comprises one fiber port and one copper port on
the device panel. The two ports share one forwarding interface, so they cannot work simultaneously.
When you enable either port, the other port is automatically disabled. You can select to activate the
copper port or fiber port as needed.
Determine the combo interfaces on your device and identify the two physical interfaces that compose
each combo interface according to the marks on the device panel.
Examples
# Activate the copper combo port of combo interface GigabitEthernet 2/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] combo enable copper
# Activate the fiber combo port of combo interface GigabitEthernet 2/0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 2/0/1
[Sysname-GigabitEthernet2/0/1] combo enable fiber
dampening
Use dampening to enable the device to dampen an interface when the interface is flapping.
Use undo dampening to restore the default.
Syntax
dampening [ half-life reuse suppress max-suppress-time ]
undo dampening
Default
Interface dampening is disabled on Ethernet interfaces.
