RackSwitch G8000 Application Guide

Configuring Multiple Spanning Tree Groups

This configuration shows how to configure MSTP Groups on the switch, as shown in Figure 5-3.

1.Configure port membership and define the Spanning Tree groups for VLAN 1.

Enable tagging on uplink ports that share VLANs. Port 51 and port 52 connect to the Enter- prise Routing switches.

RS G8000 (config)# interface port 51

RS G8000 (config-if)# tagging

RS G8000 (config-if)# exit

RS G8000 (config)# interface port 52

RS G8000 (config-if)# tagging

RS G8000 (config-if)# exit

Add server ports 1 and 2 to VLAN 1. Add uplink ports 51 and 52 to VLAN 1.

RS G8000 (config)# vlan

RS G8000 (config-vlan)#

enable

RS G8000 (config-vlan)#

RS G8000 (config-vlan)#

member 4

RS G8000 (config-vlan)#

member 5

RS G8000

RS G8000

(config-vlan)#

member 52

RS G8000

(config-vlan)#

stg 1

RS G8000

(config-vlan)#

exit

2.Configure Multiple Spanning Tree Protocol.

Configure the MSTP region name, set the Spanning-tree mode to mst, and configure the version.

RS G8000 (config)# spanning-tree mstp name MyRegion

RS G8000 (config)# spanning-tree mode mst

RS G8000 (config)# spanning-tree mstp version 100
