RSTP Configuration Commands 337
Use the undo stp timer forward-delay command to restore the default
forward delay time.
The value of forward delay is related to the “diameter” of the switching network.
The more extensive the switching network is, the longer the forward delay should
be set. You can use this command to modify the value of forward delay. The
default value, 1500, is recommended.
Related commands: stp timer hello, stp timer max-age.
Example
To set the forward delay of the device to 2000 centiseconds, enter the following:
<SW5500>system-view
System View: return to User View with Ctrl+Z.

Parameter
centiseconds
: Specifies the value of hello time in centisecond, ranging from 100
to 1000. By default, the value is 200 centiseconds.
Description
Use the stp timer hello command to configure hello time of the Switch.
Use the undo stp timer hello command to restore the default hello time.
The Ethernet Switch transmits RSTP packets every hello time seconds. A longer
hello time can ease the CPU load of the Switch, but it will also affect the
performances of RSTP in how rapidly it responds to changes. The
stp timer
hello
command can be used to modify the value of hello time. The default value
is recommended.
Related commands: stp timer forward-delay, stp timer max-age, stp
transmit-limit

<SW5500>system-view
System View: return to User View with Ctrl+Z.
