This section introduces basic configurations about logical interfaces. For the 
configurations about the data link layer, the network layer and some special 
features, refer to the relevant sections in Chapter 1 through Chapter 37 and 
Chapter 46 through Chapter 70.

broadcast-limit link number

Virtual template (VT) view

number: Maximum number of links that can send multicast or broadcast packets 
in a VT. This argument ranges from 0 to 128 and defaults to 30. The value 0 
indicates that multicast packets or broadcast packets cannot be sent.

Use the broadcast-limit link command to set the maximum number of links 
that can send multicast or broadcast packets in a VT. Use the undo 
broadcast-limit link command to restore the default setting.

When a VT has plenty of links, the system performance will be decreased if all the 
links send multicast or broadcast packets. In this case, you can use the 
broadcast-limit link command to limit the maximum number of links that can 
send multicast packets or broadcast packets.

# Set the maximum number of links that can send multicast or broadcast packets 
in VT 1 to 100.
