bridge 1x1 hello time
Configures the bridge hello time value for an individual VLAN instance. This value is the amount of time,
in seconds, between each transmission of a BPDU on any port that is the Spanning Tree root or is attempt-
ing to become the Spanning Tree root.
bridge 1x1 vid hello time seconds
Syntax Definitions
vid An existing VLAN ID number (1–4094).
seconds Hello time value in seconds (1–10).
Defaults
By default, the bridge Hello Time value is set to 2 seconds.
Platforms Supported
OmniSwitch 6250
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
