Syntax
broadcast-suppression { ratio | pps pps }
undo broadcast-suppression
View
VLAN view
Parameter
ratio: Specifies the bandwidth ratio for the maximum broadcast traffic in specific VLAN.
Its value ranges from 1 to 100 and defaults to 100. The smaller the ratio is, the less the
allowed broadcast traffic can pass.
pps pps: Specifies the maximum number of broadcast packets that can pass through a
specific VLAN per second. Its value ranges from 1 to 148800.
Description
Use the broadcast-suppression command to suppress broadcast traffic through a
VLAN. hUse the undo broadcast-suppression command to reset the allowed
broadcast traffic through a VLAN to the default value.
By default, the switch does not suppress broadcast traffic.
When the actual broadcast traffic exceeds the specified value, the system will discard
the extra packets so that the bandwidth occupied by broadcast traffic can be kept within
a specific ratio to ensure normal network operation.
A VLAN only supports one broadcast storm suppression mode at one time. If you
configure broadcast storm suppression modes multiple times for a VLAN, the latest
configuration will overwrite the previous configuration.
Example
# Allow broadcast traffic to occupy 20% bandwidth in VLAN2.
