Step Command
1. Enter system view. system-view
2. Enter Ethernet interface view. interface interface-type interface-number
3. Set speed options for autonegotiation. speed auto { 10 | 100 | 1000 } *
This function is available only for GE Layer 2 interfaces that support speed autonegotiation.
The speed and speed auto commands supersede each other. The last command that you configure takes
effect.
Configuring storm suppression
In interface or port group view, you set the maximum size of broadcast, multicast or unknown unicast
traffic allowed to be received on an interface or each interface in a port group. When the broadcast,
multicast, or unknown unicast traffic received on the interface exceeds this threshold, the system discards
packets until the traffic drops below this threshold.
Configuration restrictions and guidelines
• The storm suppression thresholds configured for an Ethernet interface may become invalid if you
enable the storm control function for the interface. For information about the storm control function,
see " Configuring storm control on an Ethernet interface ."
• To configure two or all of broadcast, multicast, and unknown unicast suppression thresholds on the
same port, do not use pps together with kbps or ratio.
• If you set a traffic suppression threshold for an Ethernet interface that belongs to a port group in both
Ethernet interface view and port group view, the most recent configuration takes effect.
Configuration procedure
To set storm suppression thresholds on one or multiple Ethernet interfaces:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter Ethernet interface view
or port group view.
• Enter Ethernet interface view:
interface interface-type
interface-number
• Enter port group view:
port-group manual
port-group-name
To configure storm suppression on
an Ethernet interface, enter
Ethernet interface view.
To configure storm suppression on
a group of Ethernet interfaces,
enter port group view.
3. Set the broadcast suppression
threshold ratio. broadcast-suppression { ratio |
pps max-pps | kbps max-kbps }
Optional.
By default, broadcast traffic is
allowed to pass through an
interface.
4. Set the multicast suppression
threshold ratio. multicast-suppression { ratio | pps
max-pps | kbps max-kbps }
Optional.
By default, multicast traffic is
allowed to pass through an
interface.
