Configuring Jumbo Frame Support; Configuring Physical State Change Suppression On An Ethernet Interface - H3C SR6602-X Configuration Manual

•
Ethernet interfaces can operate as Layer 2 Ethernet interfaces (in bridge mode).
•
Ethernet interfaces can operate as Layer 3 Ethernet interfaces (in route mode).
To configure the link mode of an Ethernet interface:
Step
1. Enter system view.
2. Enter Ethernet interface
view.
3. Configure the link mode of
the Ethernet interface.

Configuring jumbo frame support

An Ethernet interface might receive frames larger than the standard Ethernet frame size during
high-throughput data exchanges, such as file transfers. These frames are called jumbo frames.
The Ethernet interface processes jumbo frames in the following ways:
•
When the Ethernet interface is configured to deny jumbo frames, the Ethernet interface
discards jumbo frames.
•
When the Ethernet interface is configured with jumbo frame support, the Ethernet interface
performs the following operations:
Processes jumbo frames within the specified length.
Discards jumbo frames that exceed the specified length.
To configure jumbo frame support in interface view:
Step
1. Enter system view.
2. Enter Ethernet interface
view.
3. Configure jumbo frame
support.
Configuring physical state change suppression on an
Ethernet interface
IMPORTANT:
Do not enable this feature on an interface that has spanning tree protocols enabled.
The physical link state of an Ethernet interface is either up or down. Each time the physical link of an
interface comes up or goes down, the interface immediately reports the change to the CPU. The
CPU then performs the following operations:
•
Notifies the upper-layer protocol modules (such as routing and forwarding modules) of the
change for guiding packet forwarding.
•
Automatically generates traps and logs to inform users to take the correct actions.
