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

Distributed Spanning Tree Commands

spantree cist restricted-role

Configures the restricted role status for a port or a link aggregate of ports. Enabling this parameter blocks
the port from becoming the Root Port, even if it is the most likely candidate for root. Once a root port is
selected, the restricted port is selected as an Alternate Port.

Usage Guidelines
•
When running in flat mode, this is a per-port setting and is applicable to any CIST or MSTI instances
configured on that port.
•
Enabling the restricted role status is used by network administrators to prevent bridges external to the
core region of the network from influencing the Spanning Tree topology.
•
Note that enabling the restricted role status for a port may impact connectivity within the network.
