F3726, F3211, F3174, R5135, R3816-HP Firewalls and UTM Devices Network Management Command Reference-6PW100

26
Default command level
2: System level
Parameters
ratio: Sets the multicast suppression threshold as a percentage of the maximum interface rate, ranging
from 1 to 100. The smaller the percentage, the less multicast traffic is allowed to be received.
Usage guidelines
In Ethernet interface or subinterface view, the configurations take effect only on the interface or
subinterface.
When the received multicast traffic exceeds the threshold, the system discards multicast packets until
multicast traffic drops below the threshold.
If you set different multicast suppression thresholds in Ethernet interface view multiple times, the most
recent configuration last takes effect.
Examples
# Set the multicast threshold to 20% on GigabitEthernet 0/1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1
[Sysname-GigabitEthernet0/1] multicast-suppression 20
# Set the multicast threshold to 20% on Ethernet subinterface GigabitEthernet 0/1.1.
<Sysname> system-view
[Sysname] interface gigabitethernet 0/1.1
[Sysname-GigabitEthernet0/1.1] multicast-suppression 20
unicast-suppression
Use unicast-suppression to set the unknown unicast suppression threshold on an Ethernet interface or
subinterface.
Use undo unicast-suppression to restore the default.
Syntax
unicast-suppression ratio
undo unicast-suppression
Default
Ethernet interfaces do not suppress unknown unicast traffic.
Views
Layer 2 Ethernet interface view, Layer 2 Ethernet subinterface view
Default command level
2: System level
Parameters
ratio: Sets the unknown unicast suppression threshold as a percentage of the maximum interface rate,
ranging from 1 to 100. The smaller the percentage, the less unknown unicast traffic is allowed to be
received.
