R3303-HP HSR6800 Routers Interface Configuration Guide

10
To avoid congestion on GigabitEthernet 1/0/4, set 100 Mbps as the only option available for speed
negotiation on port GigabitEthernet 1/0/1, GigabitEthernet 1/0/2, and GigabitEthernet 1/0/3. As a
result, the transmission rate on each port connected to a server is limited to 100 Mbps.
To set speed options for auto negotiation on an Ethernet interface:
Step Command
1. Enter system view.
system-view
2. Enter Ethernet interface view.
interface interface-type interface-number
3. Set speed options for auto negotiation.
speed auto { 10 | 100 | 1000 } *
This function is available only for 100-Mbps or 1000-Mbps Layer 2 Ethernet interfaces that support
speed auto negotiation. Only the copper combo ports support this function.
The speed and speed auto commands supersede each other, and whichever is configured last takes
effect.
Configuring storm suppression
You can use the storm suppression function to limit the size of a particular type of traffic (broadcast,
multicast, or unknown unicast traffic) that can be received on a per-interface basis in Ethernet interface
view.
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 might 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."
• For an Ethernet interface that belongs to a port group, if you set a traffic suppression threshold for
the interface in both Ethernet interface view and port group view, the threshold configured last 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
Use one of the commands.
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.
