Configure VLANS and Display the PVRST+ Information for VLANs

You can use the show command to display the configuration details of a particular VLAN or for all of the configured VLANs. This section contains a sequence of commands to disable GVRP, configure STP mode, configure a port as a trunk port, enable VLANs, and display the STP information about the VLANs. These commands assume that no prior configuration commands have been used.

1. Disable GVRP.

   TOR-1 SEFOS# configure terminal
   TOR-1 SEFOS(config)# set gvrp disable
   TOR-1 SEFOS(config)#

2. Configure the STP mode.

   TOR-1 SEFOS(config)# spanning-tree mode pvrst
    
   PVRST is started.
   PVRST Module status is changed
    
   TOR-1 SEFOS(config)#

3. Enter the configuration mode for the interface.

   TOR-1 SEFOS(config)# interface extreme-ethernet 0/1
   TOR-1 SEFOS(config-if)#

4. Configure the port as a trunk port.

   TOR-1 SEFOS(config-if)# switchport mode trunk
   TOR-1 SEFOS(config-if)#

5. Bring up the interface.

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

6. Enable VLAN 10.

   TOR-1 SEFOS(config)# vlan 10
   TOR-1 SEFOS(config-vlan)# vlan active
   TOR-1 SEFOS(config-vlan)# exit
   TOR-1 SEFOS(config)#

7. Enable VLAN 20.

   TOR-1 SEFOS(config)# vlan 20
   TOR-1 SEFOS(config-vlan)# vlan active
   TOR-1 SEFOS(config-vlan)# end
   TOR-1 SEFOS#

8. Display the VLAN related parameters specific for port 0/1.

   TOR-1 SEFOS# show vlan port config port extreme-ethernet 0/1
    
   Vlan Port configuration table
   -------------------------------
   Port Ex0/1
    Port Vlan ID                        : 1
    Port Acceptable Frame Type          : Admit All
    Port Ingress Filtering              : Disabled
    Port Mode                           : Trunk
    Port Gvrp Status                    : Disabled
    Port Gmrp Status                    : Enabled
    Port Gvrp Failed Registrations      : 0
    Gvrp last pdu origin                : 00:00:00:00:00:00
    Port Restricted Vlan Registration   : Disabled
    Port Restricted Group Registration  : Disabled
    Mac Based Support                   : Disabled
    Subnet Based Support                : Disabled
    Port-and-Protocol Based Support     : Enabled
    Default Priority                    : 0
    Filtering Utility Criteria          : Default
    Port Protected Status               : Disabled
    -------------------------------------------------------

   After you configure the port as trunk, the port acceptable frame type must be Admin All. If the frame type is not Admin All, use the switchport acceptable-frame-type all command in port interface mode to accept all types of packets.

9. Review the STP information.
