You can display the OSPF passive information for a particular VLAN, as shown in Example 92
(page 165).

Configuring the calculation interval
Syntax:
[no] spf-throttle start-interval [1-600] wait interval [1-600]
max-wait-time [1-600]
Enables and configures SPF scheduling (throttling.) This delays SPF calculations
during periods of network topology changes.
SPF calculations occur at the interval set by the spf-throttle command. This
command is executed in ospf context.
Default: 5 seconds
start-interval [1–600] Specifies the initial SPF schedule delay in
seconds.
wait-interval [1–600] specifies the amount of time to wait until the
next SPF calculation occurs, in seconds.
max-wait-time [1–600] Specifies the maximum time between two
consecutive SPF calculations, in seconds.
The current SPF interval is calculated; it will be twice as long as the previous interval
until this value reaches the maximum-wait-time specified.
