Parameters
ratio: Maximum bandwidth ratio of broadcast traffic allowed in the specified VLAN. Its
value ranges from 1 to 100 and defaults to 100. The smaller the ratio is, the less the
broadcast traffic can pass through the VLAN.
pps pps: Specifies the maximum number of broadcast packets that can pass through a
specific VLAN per second. Its value ranges from 1 to 148,800.
Description
Use the broadcast-suppression command to suppress broadcast traffic through a
VLAN.
Use 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.
The cards of S7500 series switches support different broadcast storm suppression
modes, as listed in
Table 1-1.
