Virtual-Cable-Test - H3C S7500E Series Command Reference Manual

For a Gigabit port, the value range is 1 to 1000000.
For a 10-Gigabit port, the value range is 1 to 10000000.
Description
Use the unicast-suppression command to set the unknown unicast suppression threshold on an
Ethernet interface view or a group of Ethernet interfaces in port group view.
Use the undo unicast-suppression command to restore the default.
By default, Ethernet interfaces do not suppress unknown unicast traffic.
If you execute this command in Ethernet interface view, the configurations take effect only on the
current interface. If you execute this command in port-group view, the configurations take effect on all
ports in the port group
When unknown unicast traffic exceeds the threshold you configure, the system discards unknown
unicast packets until the unknown unicast traffic drops below the threshold.
If you set different unknown unicast suppression thresholds in Ethernet interface view or
port-group view multiple times, the one configured last takes effect.
For a particular type of traffic, configure either storm suppression or storm control, but not both. If
both of them are configured, you may fail to achieve the expected storm control effect.
