Configuring RRSTP
This section describes how to use Alcatel-Lucent’s Command Line Interface (CLI) commands to config-
ure Ring Rapid Spanning Tree Protocol (RRSTP) on a switch.
When configuring RRSTP parameters, you must perform the following steps:
1 Enable RRSTP on your switch. To enable RRSTP globally on a switch, use the bridge rrstp
command, which is described in “Enabling and Disabling RRSTP” on page 7-40.
2 Create RRSTP ring comprising of two ports. To create an RRSTP ring comprising of two ports, use
the bridge rrstp ring command, which is described in “Creating and Removing RRSTP Rings” on
page 7-40.
Enabling and Disabling RRSTP
To enable RRSTP switch-wide, use the bridge rrstp command by entering:
-> bridge rrstp
To disable RRSTP switch-wide, use the no form of the command by entering:
-> no bridge rrstp
You can display the current RRSTP status at a global level using the show bridge rrstp configuration
command.
-> show bridge rrstp configuration
RRSTP Global state is Enabled
Creating and Removing RRSTP Rings
By default, an RRSTP ring is disabled on the switch. To create an RRSTP ring comprising of two ports,
use the bridge rrstp ring command by entering:
-> bridge rrstp ring 1 port1 1/1 port2 1/3 vlan-tag 10 status enable
To modify the vlan-tag associated with the ring, use the bridge rrstp ring vlan-tag command by entering:
-> bridge rrstp ring 1 vlan-tag 20
To remove an RRSTP ring comprising of two ports, use the no form of the command by entering:
-> no bridge rrstp ring 1
You can display the information of a specific ring or all the rings on the switch using the show bridge
rrstp ring command, as shown:
-> show bridge rrstp ring
RingId Vlan-Tag Ring-Port1 Ring-Port2 Ring Status
