Description
Use this command to configure the spanning-tree bridge hello time, which determines how often
the device broadcasts hello messages to other devices. Use the no hello-time command to return
to the default settings.
Usage
Guidelines
When configuring the hello-time, the max-age setting must be greater than the hello-time setting.
The following relationship should be kept:
2*(forward-delay - 1)>=max-age>=2*(hello-time + 1)
Examples
To configure spanning-tree bridge hello time to 5 seconds:
switch(conf-stp)#hello-time 5
