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.
Different modules of Switch 7750s support different broadcast storm suppression
modes, as listed in Table 49.

Operation

enter VLAN interface view
Specify the description string
for the current VLAN interface
Disable the VLAN interface
Enable the VLAN Interface
Note that the operation of enabling/disabling a VLAN interface does not influence
the enabling/disabling states of the Ethernet ports belonging to this VLAN.
By default, a VLAN interface is enabled. In this scenario, the VLAN interface's
status is determined by the status of its ports, that is, if all the ports of the VLAN
interface are down, the VLAN interface is down (disabled); if one or more ports of
the VLAN interface are up, the VLAN interface is up (enabled).
