Usage Guidelines
•
Lowering the Hello Time interval improves the robustness of the Spanning Tree Algorithm. Increasing
the Hello Time interval lowers the overhead of the Spanning Tree Algorithm.
•
This command is an explicit Spanning Tree command that only applies to the specified VLAN instance
regardless of which operating mode (flat or 1x1) is active on the switch.
•
If the switch is running in the flat mode when this command is used, the specified hello time value is
not active for the specified VLAN instance until the operating mode for the switch is changed to the
1x1 mode.
•
Note that when a configuration snapshot is taken of the switch, all Spanning Tree commands are saved
in their explicit format.
Examples
-> bridge mode flat
-> bridge 1x1 2 hello time 5
-> bridge 1x1 10 hello time 10
-> bridge mode 1x1
-> bridge 1x1 255 hello time 5
-> bridge 1x1 455 hello time 10
