Enables restricted role on the specified port inside the core network.
| stpd_name | Specifies an STPD name on the switch. |
| port_list | Specifies one or more ports or slots and ports. |
N/A.
Enabling restricted role causes the port not to be selected as a root port even if it has the best spanning tree priority vector. Such a port is selected as an alternate port after the root port has been selected.
The restricted role is disabled by default. If set, it can cause a lack of spanning tree connectivity. A network administrator enables the restricted role to prevent bridges external to a core region of the network from influencing the spanning tree active topology, possibly because those bridges are not under the full control of the administrator.
Note
Restricted role should not be enabled with edge mode.
Enabling Restricted Role at CIST is inherited by all MSTI.
The following command enables restricted role on port 6:3:
configure stpd s1 ports restricted-role enable 6:3
