%Jun 6 11:48:44:860 2010 Sysname CMD/4/REBOOT: vty0(192.168.1.54): Set schedule reboot parameters at 11:48:44 06/06/2010, and system will reboot at 13:16 06/06/2010. shutdown-interval Syntax shutdown-interval time View undo shutdown-interval System view Default level 2: System level Parameters time: Specifies the port status detection timer in seconds, which ranges from 0 to 300. Description Use shutdown-interval to set the port status detection timer. Use undo shutdown-interval to restore the default. By default, the timer is 30 seconds. Some protocols might shut down ports under specific circumstances. For example, MSTP shuts down a BPDU guard enabled port when the port receives a BPDU. Then, the device starts the detection timer. If the port is still down when the detection timer expires, the port quits the shutdown status and resume its actual physical status. • If you change the detection timer to T1 during port detection, the timer from when you change the timer to the time when the protocol module shuts down the port is T. If T=T1, the port resume its actual physical status immediately. For example, if the detection timer is set to 30 seconds and you change it to 10 seconds (T1=10) two seconds after the port is shut down (T=2), this port resume its actual physical status 8 seconds later. If the detection timer is set to 30 seconds and you change it to 2 seconds ten seconds after the port is shut down, this port resume its actual physical status immediately. • If the detection timer is set to 0, the protocol module will never automatically recover the port. You need to manually bring up the port by using the undo shutdown command or change the detection timer to a non-zero value.

Default level
2: System level
Parameters
time
: Specifies the port status detection timer in seconds, which ranges from 0 to 300.
Description
Use
shutdown-interval
to set the port status detection timer.
Use
undo
shutdown-interval
to restore the default.
By default, the timer is 30 seconds.
Some protocols might shut down ports under specific circumstances. For example, MSTP shuts down a
BPDU guard enabled port when the port receives a BPDU. Then, the device starts the detection timer. If
the port is still down when the detection timer expires, the port quits the shutdown status and resume its
actual physical status.
•
If you change the detection timer to T1 during port detection, the timer from when you change the
timer to the time when the protocol module shuts down the port is T. If T<T1, the port resume its
actual physical status after T1-T time. If T>=T1, the port resume its actual physical status immediately.
For example, if the detection timer is set to 30 seconds and you change it to 10 seconds (T1=10)
two seconds after the port is shut down (T=2), this port resume its actual physical status 8 seconds
later. If the detection timer is set to 30 seconds and you change it to 2 seconds ten seconds after the
port is shut down, this port resume its actual physical status immediately.
•
If the detection timer is set to 0, the protocol module will never automatically recover the port. You
need to manually bring up the port by using the
undo shutdown
command or change the detection
timer to a non-zero value.

# Set the port status detection timer to 100 seconds.
