Usage guidelines Before collecting traffic statistics for a specific period of time on an interface, clear the old statistics first. If no interface type is specified, this command clears statistics for all interfaces. If only the interface type is specified, this command clears statistics for all interfaces of that type. If both the interface type and the interface number are specified, this command clears statistics for the specified interface.
Page 34: Speed
Syntax shutdown undo shutdown Default Ethernet interfaces are in up state. Views Ethernet interface view Predefined user roles network-admin Usage guidelines You might need to shut down and then bring up an Ethernet interface to make some interface configurations take effect. Examples # Shut down and then bring up Ten-GigabitEthernet 1/0/1.
Page 35: Storm-Constrain
Usage guidelines 10-GE interfaces support only 1000, 10000, and auto keywords of the command. 40-GE interfaces support only the 40000 and auto keywords of the command. For a fiber port, use the speed command to set its speed to match the rate of a transceiver module. Examples # Configure Ten-GigabitEthernet 1/0/1 to autonegotiate the speed.
Page 36: Storm-Constrain Control
Either of the storm-constrain, broadcast-suppression, multicast-suppression, and unicast-suppression commands can suppress storm on a port. The storm-constrain command uses software to suppress traffic, affects device performance certain extent. broadcast-suppression, multicast-suppression, and unicast-suppression commands use the chip to physically suppress traffic, and have less influence on the device performance compared with the storm-constrain command.
Page 37: Storm-Constrain Enable Log
Predefined user roles network-admin Parameters block: Blocks this type of traffic, while forwarding other types of traffic. Even though the interface does not forward the blocked traffic, it still counts the traffic. When the blocked traffic is detected dropping below the lower threshold, the port begins to forward the traffic. shutdown: Shuts down automatically.
Page 38: Storm-Constrain Enable Trap
storm-constrain enable trap Use storm-constrain enable trap to enable an Ethernet interface to send storm control threshold event traps. Use undo storm-constrain enable trap to disable trap sending. Syntax storm-constrain enable trap undo storm-constrain enable trap Default An interface sends out traps when monitored traffic exceeds the upper threshold or falls below the lower threshold.
Page 39: Unicast-Suppression
Usage guidelines The interval set by the storm-constrain interval command is specific to storm control. To set the statistics polling interval of an interface, use the flow-interval command. For network stability, use the default or a higher polling interval. Examples # Set the traffic statistics polling interval of the storm control module to 60 seconds.
Page 40: Using Fortygige
Both the storm-constrain and unicast-suppression can suppress unicast storm on a port. The storm-constrain command uses software to suppress unicast traffic, and it affects the device performance to a certain extent. The unicast-suppression command use the chip to physically suppress unicast traffic, and it has less influence on the device performance than the storm-constrain command.

Bulk interface configuration commands interface range Use interface range to create an interface range and enter the interface range view. Syntax interface range interface-list Views System view Predefined user roles network-admin Parameters interface-list: Specifies an interface list in the format of interface-list = { interface-type interface-number [ to interface-type interface-number ] }&<1-5>.

Use interface range name name without the interface keyword to enter the view of an interface range with the specified name.
Page 54 The maximum number of interface range names is only limited by the system resources. To • guarantee bulk interface configuration performance, HP recommends configuring fewer than 1000 interface range names. Examples # Add Ten-GigabitEthernet 1/0/1 through Ten-GigabitEthernet 1/0/12 to interface range named myEthPort, and enter the interface range view.

Usage guidelines A VLAN interface that was shut down with the shutdown command remains in DOWN (Administratively) state until you bring it up, regardless of how the state of the ports in the VLAN changes. Before you configure parameters for a VLAN interface, shut down the VLAN interface with the shutdown command to prevent the configurations from affecting the network.
Page 157: Port-Based Vlan Commands
You cannot create or remove VLANs that are reserved for specific functions. You cannot use the undo vlan command to delete a dynamic VLAN, a VLAN with a QoS policy applied, or a VLAN locked by an application. To delete such a VLAN, first remove the configuration from the VLAN.
