NOTE
When MSTP Fast Ring is used, all of the user ports must be configured as MSTP
edge ports. Use the
mstp edge port
command in the Interface Configuration mode.
The MSTP Fast Ring mode is disabled by default. To set the MSTP Fast Ring mode, use the
mstp
fast-ring ring-ports
command
in Protocol Configuration mode. To set the Interoperability Fast
Ring mode, use the
mstp fast-ring border-bridge
command
in Protocol Configuration mode.
NOTE
Border bridges have to be configured differently from the other ring bridges. In
order to configure the border bridges, use the following command in Protocol
Configuration mode:
mstp fast-ring 0 border-bridge ports preferred-link {
UU/SS/PP
| AG
N
}
