Spantree Cist Mode - Alcatel-Lucent 060321-10, Rev. B Cli Reference Manual

Distributed Spanning Tree Commands

spantree cist mode

Configures manual mode (forwarding or blocking) or dynamic mode to manage the state of a port or a link
aggregate of ports for the flat mode Common and Internal Spanning Tree (CIST) instance. Dynamic mode
defers the management of the port state to the Spanning Tree algorithm.
spantree cist {port slot/port[-port2] | linkagg linkagg_id[-linkagg_id2]} mode {forwarding |
dynamic | blocking}
Syntax Definitions
slot/port[-port2]
linkagg_id[-linkagg_id2]
forwarding
dynamic
blocking
Defaults
By default, the port Spanning Tree mode is set to dynamic.
Platforms Supported
OmniSwitch 10K
Usage Guidelines
•
This command only applies to the port Spanning Tree mode for the CIST instance regardless of which
operating mode (flat or per-VLAN) is active for the switch.
•
If the switch is running in per-VLAN mode when this command is used, the specified port mode is not
active for the CIST instance until the operating mode for the switch is changed to the flat mode.
•
Ports manually configured to operate in a forwarding or blocking state do not participate in the
Spanning Tree algorithm.
•
When port state is manually set to forwarding or blocking, the port remains in that state until it is
changed using this command.
Examples
-> spantree cist port 4/1 mode forwarding
-> spantree cist port 4/2-5 mode forwarding
-> spantree cist linkagg 10 mode blocking
-> spantree cist linkagg 15-20 mode forwarding
