Setting point-to-point link

You can set a point-to-point link between ports to increase the speed of convergence. To create a
point-to-point link between ports, use a command such as the following at the Global Configuration
level.
BigIron RX(config)# mstp admin-pt2pt-mac ethernet 2/5 ethernet 4/5
Syntax: [no] mstp admin-pt2pt-mac ethernet <slot/port>
The <slot/port> parameter specifies a port or range of ports to be configured for point-to-point
links to increase the speed of convergence.

Disabling MSTP on a port

To disable MSTP on a specific port, use a command such as the following at the Global
Configuration level.
BigIron RX(config)# mstp disable 2/1
Syntax: [no] mstp disable <slot/port>
The <slot/port> variable specifies the location of the port that you want to disable MSTP for.

Forcing ports to transmit an MSTP BPDU

To force a port to transmit an MSTP BPDU, use a command such as the following at the Global
Configuration level.
BigIron RX(config)# mstp force-migration-check ethernet 3/1
Syntax: [no] mstp force-migration-check ethernet <slot/port>
The <slot/port> variable specifies the port or ports that you want to transmit an MSTP BPDU from.

Enabling MSTP on a switch

To enable MSTP on your switch, use a command such as the following at the Global Configuration
level.
BigIron RX(config)#mstp start
Syntax: [no] start
