Command Description:

Use the set spantree hello command to set the bridge hello time for a VLAN or an instance.


Example:

This example shows how to set the spantree hello time for VLAN 100 to 3 seconds:

Console> (enable) set spantree hello 3 100
Spantree 100 hello time set to 3 seconds.
Console> (enable)
 

This example shows how to set the spantree hello time for an instance to 3 seconds:

Console> (enable) set spantree hello 3 mistp-instance 1

Spantree 1 hello time set to 3 seconds.
Console> (enable)

 


Misconceptions:

If you do not specify a VLAN number or an instance number, 1 is assumed.

This command is not supported by the NAM.

If you enable MISTP, you cannot set the VLAN hello time.

If you enable PVST+, you cannot set the instance hello time.

If you enter the set spantree hello interval mst command, you set the hello time for the IST instance and all MST instances. You do not need to set the hello time for each MST instance.
