Setting The Media Type For An Ethernet Interface; Configuring Interface Alarm Functions - H3C S6850 Series Configuration Manual

Setting the media type for an Ethernet interface

Restrictions and guidelines
For 25-GE interfaces on an LSWM124TG2H interface module, you must set the media type. Set the
media type to fiber for an interface that uses a transceiver module or fiber cable. Set the media
type to copper for an interface that uses a copper cable. The media type of interfaces in the same
group is the same. When you set the media type for any interface in a group, the setting is
synchronized to the other interfaces in the group.
This configuration fails when an interface group has any service loopback interface or reflector port
for mirroring.
When you configure this feature for an interface through the preprovisioning feature, the
configuration on the interface is not automatically synchronized to the other interfaces in the same
group. For more information about preprovisioning, see preprovisioning configuration in
Fundamentals Configuration Guide.
Procedure
1. Enter system view.
system-view
2. Enter Ethernet interface view.
interface interface-type interface-number
3. Set the media type for the Ethernet interface.
port media-type { copper | fiber }
By default, the media type of an Ethernet interface is fiber.

Configuring interface alarm functions

About interface alarm functions
With the interface alarm functions enabled, when the number of error packets on an interface in
normal state within the specified interval exceeds the upper threshold, the interface generates an
upper threshold exceeding alarm and enters the alarm state. When the number of error packets on
an interface in the alarm state within the specified interval drops below the lower threshold, the
interface generates a recovery alarm and restores to the normal state.
Restrictions and guidelines
An interface that is shut down because of error packet alarms cannot automatically recover. To bring
up the interface, execute the undo shutdown command on the interface.
Enabling interface alarm functions
1. Enter system view.
system-view
2. Enable alarm functions for the interface monitoring module.
snmp-agent trap enable ifmonitor { crc-error | input-error |
output-error } *
By default, all alarm functions are enabled for interfaces.
Configuring CRC error packet parameters
1. Enter system view.
system-view
2. Enter Ethernet interface view.
