Version Description
9.11(0.0) Introduced the msec keyword.
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
Setting the delay and holdtime parameters to a low number enables the switch to an alternate path
quickly but requires more CPU usage.

timers throttle lsa all
Configure LSA transmit intervals.
Syntax
timers throttle lsa all {start-interval | hold-interval | max-interval}
To return to the default, use the no timers throttle lsa command.
Parameters
start-interval Set the minimum interval between initial sending and resending the same LSA. The
range is from 0 to 600,000 milliseconds.
hold-interval Set the next interval to send the same LSA. This interval is the time between
sending the same LSA after the start-interval has been attempted. The range is
from 1 to 600,000 milliseconds.
max-interval Set the maximum amount of time the system waits before sending the LSA. The
range is from 1 to 600,000 milliseconds.
Defaults
● start-interval: 0 msec
● hold-interval: 5000 msec
● max-interval: 5000 msec
Command Modes ROUTER OSPF
Supported Modes Full–Switch

Version Description
9.9(0.0) Introduced on the FN IOM.
8.3.16.1 Introduced on the MXL 10/40GbE Switch IO Module.
Usage
Information
LSAs are sent after the start-interval and then after hold-interval until the maximum interval is reached. In
throttling, exponential backoff is used when sending same LSA, so that the interval is multiplied until the
maximum time is reached. For example, if the start-interval 5000 and hold-interval 1000 and max-interval
100,000, the LSA is sent at 5000 msec, then 1000 msec, then 2000 msec, them 4000 until 100,000 msec
is reached.
