keepalive periods and shuts down the link. To prevent the situation, set the interval for sending keepalive
packets relatively longer.
Examples
# Set the interval for sending keepalive packets to 20 seconds on interface Virtual-Template 10.

Default level
2: System level
Parameters
number: Maximum number of links that can be used for transmitting multicast or broadcast packets, in
the range 0 to 128. The value 0 indicates that the transmission of multicast or broadcast packets is not
supported.
Description
Use broadcast-limit link to set the maximum number of links that can be used for transmitting multicast
packets or broadcast packets for the VT interface.
Use undo broadcast-limit link to restore the default.
By default, the maximum number of links that can be used for transmitting multicast or broadcast packets
is 30 for a VT interface.
For a VT interface containing multiple links, the system performance might degrade if all the links of the
VT interface are engaged in multicast or broadcast packet transmission. You can use the broadcast-limit
link command to limit the number of links that are capable of multicast or broadcast packet transmission.
Examples
# Set the maximum number of links that are capable of multicast or broadcast packets transmission to
100 for interface Virtual-Template 1.
<Sysname> system-view
[Sysname] interface virtual-template 1
[Sysname-Virtual-Template1] broadcast-limit link 100
