Configuring the Hello Time

The hello time is the time interval between configuration messages generated and sent by the root switch.
This procedure is optional.
Beginning in privileged EXEC mode, follow these steps to configure the hello time for all MST instances.
Before You Begin
A multiple spanning tree (MST) must be specified and enabled on the switch. For instructions, see Related

Purpose
Enters the global configuration mode.
Configures the switch priority.
• For instance-id, you can specify a single instance, a range of instances
separated by a hyphen, or a series of instances separated by a comma.
The range is 0 to 4094.
• For priority, the range is 0 to 61440 in increments of 4096; the default
is 32768. The lower the number, the more likely the switch will be
chosen as the root switch.
Priority values are 0, 4096, 8192, 12288, 16384, 20480, 24576, 28672,
32768, 36864, 40960, 45056, 49152, 53248, 57344, and 61440. These
are the only acceptable values.
Returns to privileged EXEC mode.
