bridge 1x1 slot/port priority
Configures the Spanning Tree priority value for a port or an aggregate of ports for the specified 1x1 mode 
VLAN instance. The Spanning Tree algorithm uses the port priority value to determine the most favor-
able port when a bridge has multiple ports with the same path cost to the root bridge. 
bridge 1x1 vid {slot/port | logical_port} priority priority
Syntax Definitions
vid
An existing VLAN ID number (1–4094).
slot/port
Enter the slot number for the module and the physical port number on 
that module (e.g., 3/1 specifies port 1 on slot 3).
logical_port
Link aggregate ID number (0–31).
priority
Port priority value (0–15). The lower the number, the higher the 
priority.
Defaults
By default, the bridge port priority value is set to 7.
Platforms Supported
OmniSwitch 6400, 6850, 6855, 9000, 9000E
Usage Guidelines
• The port priority specifies the value of the priority field contained in the first byte of the Port ID. The 
second byte contains the physical switch port number.
• This command is an explicit Spanning Tree command that only applies to the specified VLAN instance 
regardless of which operating mode (flat or 1x1) or protocol is active on the switch.
• If the switch is running in the flat mode when this command is used, the specified priority value for the 
port 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.
