Configuring A Port Group; Configuring Storm Suppression - HP 4800G Series Configuration Manual

To do...
Enable loopback testing
As for the internal loopback test and external loopback test, if an interface is down, only the former
is available on it; if the interface is shut down, both are unavailable.
The speed, duplex, mdi, and shutdown commands are not applicable during loopback testing.
With the loopback testing enabled, the Ethernet interface operates in full duplex mode. With the
loopback testing disabled, the original configurations will be restored.

Configuring a Port Group

The devices allow you to configure some functions on multiple interfaces at a time by assigning the
interfaces to a port group in addition to configuring them on a per-interface basis. This is helpful when
you have to configure a feature in the same way on multiple interfaces.
A port group is created manually and the settings you made on it apply to all group member interfaces.
Note that even though the settings are made on the port group, they are saved on an interface basis
rather than on a port group basis. Thus, you can only view the settings in the view of each interface with
the display current-configuration command or the display this command.
Follow these steps to configure a manual port group:
Enter system view
Create a manual port group and enter
manual port group view
Add Ethernet interfaces to the manual
port group

Configuring Storm Suppression

You can use the following commands to suppress the broadcast, multicast, and unknown unicast traffic.
In interface configuration mode, the suppression ratio indicates the maximum broadcast, multicast or
unknown unicast traffic that is allowed to pass through an interface. When the broadcast, multicast, or
unknown unicast traffic over the interface exceeds the threshold, the system will discard the extra
packets so that the broadcast, multicast or unknown unicast traffic ratio can drop below the limit to
ensure that the network functions properly.
