SPANNING-TREE HELLO-TIME
Syntax
spanning-tree hello-time <1-10>
no spanning-tree hello-time
Parameters
none
Description
Use the SPANNING-TREE HELLO-TIME command to set the hello-time,
the time in seconds after which (if this bridge is the root bridge) all the
bridges in a bridged LAN exchange Bridge Protocol Data Units (BPDUs).
A very low value of this command leads to excessive traffic on the
network, while a higher value delays the detection of topology change.
This value is used by all instances.
To restore the default value of the hello time, use the no form of this
command.
Command Mode
Configuration Terminal mode
Example
The following commands set the hello delay time to 9 seconds:
switch#configure terminal
switch(config)#spanning-tree hello-time 9
