Configure Switch ToR72p-1 for L2 PVRST - Oracle Ethernet Switches

Configure Switch `ToR72p-1` for L2 PVRST

Start the configuration with all ports and the default VLAN shutdown.

Tip - It is a best practice to start the configuration with all the ports and default VLAN shutdown. Disable GVRP and GMRP because dynamic VLAN learning is not suggested.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# set gvrp disable
ToR72p-1 SEFOS(config)# set gmrp disable
ToR72p-1 SEFOS(config)# set port-channel enable
ToR72p-1 SEFOS(config)# interface vlan 1
ToR72p-1 SEFOS(config-if)# shutdown
ToR72p-1 SEFOS(config-if)# no ip address
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface range extreme-ethernet 0/1-72
ToR72p-1 SEFOS(config-if-range)# shutdown
ToR72p-1 SEFOS(config-if-range)# end

Create and enable port-channels between switches per the topology.

See L2 and L3 Topology.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# interface port-channel 10
ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface port-channel 12
ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface port-channel 14
ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# end

Configure VLANs manually.

You must add at least one port to the VLAN before you can assign the VLAN a name.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# vlan 300
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name external-vlan-1
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 301
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name external-vlan-2
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 302
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name external-vlan-3
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 303
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name external-vlan-4
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 200
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name internal-vlan-1
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 201
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name internal-vlan-2
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 202
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name internal-vlan-3
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# vlan 203
ToR72p-1 SEFOS(config-vlan)# ports add extreme-ethernet 0/66 name internal-vlan-4
ToR72p-1 SEFOS(config-vlan)# vlan active
ToR72p-1 SEFOS(config-vlan)# exit
ToR72p-1 SEFOS(config)# end

Configure the port-channels to allow all VLANs.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# interface port-channel 10
ToR72p-1 SEFOS(config-if)# switchport mode trunk
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface port-channel 12
ToR72p-1 SEFOS(config-if)# switchport mode trunk
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface port-channel 14
ToR72p-1 SEFOS(config-if)# switchport mode trunk
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# end

Enable the ports and add them to the appropriate port-channels.

Configure the host port to allow all VLANs.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# interface extreme-ethernet 0/66
ToR72p-1 SEFOS(config-if)# description "connected to nxge1 Host-2"

ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit

Enable the uplink interfaces to the core switch and add them to port-channel.

ToR72p-1 SEFOS(config)# interface extreme-ethernet 0/69
ToR72p-1 SEFOS(config-if)# description "connected to Core switch on g1/1"
ToR72p-1 SEFOS(config-if)# speed 1000
ToR72p-1 SEFOS(config-if)# channel-group 10 mode active
ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# interface extreme-ethernet 0/70
ToR72p-1 SEFOS(config-if)# description "connected to Core switch on g1/4"
ToR72p-1 SEFOS(config-if)# speed 1000
ToR72p-1 SEFOS(config-if)# channel-group 10 mode active
ToR72p-1 SEFOS(config-if)# no shutdown
ToR72p-1 SEFOS(config-if)# exit
ToR72p-1 SEFOS(config)# end

Change the spanning-tree mode to PVRST and configure the bridge priority such that ToR72p-1 is root for all internal VLANs.

Tip - It is a best practice to configure the default VLAN and external VLAN priority to a higher value than the default priority 32768. Doing so makes the core switch become the root even if the default and external VLANs are configured with default priority in the core switch. Thus, only required and not all core traffic reaches ES1-24p-n.

ToR72p-1 SEFOS# configure terminal
ToR72p-1 SEFOS(config)# spanning-tree mode pvrst
Spanning Tree enabled protocol is MSTP, now MSTP is being shutdown PVRST is started.
