Configuring The Cable Type For An Ethernet Port; Configuring The Storm Constrain Function On An Ethernet Port - H3C S7500E Series Operation Manual

Operation Manual – Port Correlation Configuration
H3C S7500E Series Ethernet Switches
Caution:
Loopback detection on a given port is enabled only after the loopback-detection
enable command has been issued in both system view and the port view of the port.
Loopback detection on all ports will be disabled after the issuing of the undo
loopback-detection enable command in system view.
The aggregation port can not support loopback detection.

1.1.10 Configuring the Cable Type for an Ethernet Port

Two types of Ethernet cables can be used to connect Ethernet devices: crossover
cable and straight-through cable. To accommodate these two types of cables, an
Ethernet interface on a device can operate in one of the following three Medium
Dependent Interface (MDI) modes:
Across mode, where the Ethernet interface only accepts crossover cables.
Normal mode, where the Ethernet interface only accepts straight-through cables.
Auto mode, where the Ethernet interface accepts both straight-through cables and
crossover cables.
Normally, the auto mode is recommended. The other two modes are useful only when
the device cannot determine the cable type.
Follow these steps to configure the cable type for an Ethernet Port:

1.1.11 Configuring the Storm Constrain Function on an Ethernet Port

The storm constrain function suppresses packet storm in an Ethernet. With this function
enabled on a port, the system detects the unicast traffic, multicast traffic, or broadcast
traffic passing through the port periodically and takes corresponding actions (that is,
blocking or shutting down the port and sending trap messages and logs) if the traffic
detected exceeds the threshold.
To do... Use the command...
