Virtual-Cable-Test - HP 3100 v2 Series Command Reference Manual

If you execute this command in Ethernet interface view, the configurations take effect only on the
interface. If you execute this command in port group view, the configurations take effect on all ports
in the port group.
When you configure the suppression threshold in kbps, the actual suppression threshold might be
different from the configured one as follows:
•
If the configured value is smaller than 64, the value of 64 takes effect.
•
If the configured value is greater than 64 but not a multiple of 64, the multiple of 64 that is
greater than and closest to the configured value takes effect.
When unknown unicast traffic exceeds the threshold you configure, the system discards unknown
unicast packets until the unknown unicast traffic drops below the threshold.
NOTE:
• 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.
Examples
# Set the unknown unicast threshold to 20% on Ethernet 1/0/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] unicast-suppression 20
# Set the unknown unicast threshold to 20% on all ports of port group group1.
<Sysname> system-view
[Sysname] port-group manual group1
[Sysname-port-group-manual-group1] group-member ethernet 1/0/1
[Sysname-port-group-manual-group1] group-member ethernet 1/0/2
[Sysname-port-group-manual-group1] unicast-suppression 20
# Set the unicast suppression threshold to 10000 kbps on Ethernet 1/0/1.
<Sysname> system-view
[Sysname] interface ethernet 1/0/1
[Sysname-Ethernet1/0/1] unicast-suppression kbps 10000
Info: The actual value is 10048 on this port currently.
