Spf-Delay-Interval; Spf-Slice-Size - 3Com 8807 Command Reference Manual

Integrated IS-IS Configuration Commands 491
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.

Parameter
number: Specifies number of routes to process before releasing CPU. It is in unit of
piece with the range from 1000 to 50000. By default, the value is 2500 pieces.
Description
Use the spf-delay-interval command to configure the number of routes to
process before 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 number argument 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 2500 pieces of routes are processed.
Related command: spf-slice-size.
Example
# Set IS-IS to release CPU once after processing every 3000 pieces of routes.
