H3C S7500 Series Ethernet Switches Chapter 4 Integrated IS-IS Configuration Commands
4-33
The silent-interface command just suppresses IS-IS packet sending on this interface.
However, these IS-IS packets can still be sent on other interfaces.
Examples
# Prohibit IS-IS packet sending on VLAN-interface 3.
<H3C>system-view
System View: return to User View with Ctrl+Z.

4.1.38 spf-delay-interval
Syntax
spf-delay-interval number
undo spf-delay-interval
View
IS-IS view
Parameters
number: Interval of releasing CPU during route calculation, in the range of 1,000 routes
to 50,000 routes. It is 5,000 routes by default.
Description
Use the spf-delay-interval command to set the interval of releasing CPU during SPF
calculation.
Use the undo spf-delay-interval command to restore the default value.
When there are too many routes in the routing table, you can use this command to
release CPU automatically after a certain number of routes are processed in order to
prevent the SPF calculation from occupying the system resources for a long time, thus
affecting the response of the console. The unprocessed routes are to be processed in
one second.
You can adjust the number argument according to the size of the routing table. If the
spf-slice-size command is configured at the same time, the SPF calculation will be
paused if the SPF calculation matches any of the setting.
By default, CPU is released when every 5,000 routes are processed.
Related commands: spf-slice-size.
Examples
# Set IS-IS to release CPU when every 3,000 routes are processed.
