184 CHAPTER 5: USING ROUTING PROTOCOL COMMANDS
Parameter
silent_interface_type: Specifies the interface type.
silent_interface_number: Specifies the interface number.
Description
■ Use the silent-interface command to disable a specified interface to
transmit IS-IS packet.
■ Use the undo silent-interface command to enable the interface to transmit
IS-IS packet.
By default, all the interface are allowed to transmit/receive IS-IS packets.
The silent-interface command is only used to suppress the packets to be
transmitted on the interface, but the routes of this interface will still be
transmitted from other interfaces.
Example
Prohibit the IS-IS packets to be transmitted via Interface Vlan-interface 3.

spf-delay-interval Syntax
spf-delay-interval number
undo spf-delay-interval
View
IS-IS view
Parameter
number: Interval for actively releasing CPU in route calculation. It is in unit of piece
with the range from 1000 to 50000. By default, the value is 5000 pieces.
Description
■ Use the spf-delay-interval command to configure the interval for actively
releasing CPU in the SPF calculation.
■ Use the undo spf-delay-interval command to restore the default setting.
When there are a large number of routes in the routing table, this command can
be used to set that CPU resources are released automatically after a certain
number of routes are processed. The unprocessed routes will be processed in one
second. In this way, SPF calculation will not occupy the system resources for a long
time, which has impact on the responding speed of the console.
The value of the parameter number can be adjusted according to the capacity of
the routing table. If the spf-slice-size command is also configured, the SPF
calculation will be paused when any setting item is met.
By default, CPU is released once when every 5000 pieces of routes are processed.
Related command: spf-slice-size.
