Create Acceptable Frame Types

To work with acceptable frame types, you must ensure that the follow prerequisites are met:

See Default Settings for the topology for this procedure.

  1. Configure the VLAN in switch 1.
    SEFOS# configure terminal
    SEFOS(config)# vlan 15
    SEFOS(config-vlan)# ports extreme-ethernet 0/15,0/19 untagged extreme-ethernet 0/15,0/19
    SEFOS(config-vlan)# exit
    SEFOS(config)# interface extreme-ethernet 0/15
    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# switchport pvid 5
    SEFOS(config-if)# exit
    SEFOS(config)# interface extreme-ethernet 0/19
    SEFOS(config-if)# no shutdown
    SEFOS(config-if)# switchport pvid 5
    SEFOS(config-if)# end
  2. Wait for at least 30 seconds for the topology to settle, then ping host B from host A.

    The ping must be successful.

  3. On switch 1, configure the acceptable frame type for port P15.
    SEFOS# configure terminal
    SEFOS(config)# interface extreme-ethernet 0/15
    SEFOS(config-if)# switchport acceptable-frame-type tagged
    SEFOS(config-vlan)# end
  4. Review the VLAN-related configurations.
    SEFOS# show vlan id 5
    Vlan database
    Vlan ID             : 5
    Member Ports        : Ex0/15, Ex0/19
    Untagged Ports      : Ex0/15, Ex0/19
    Forbidden Ports     : None
    Name                :
    Status              : Permanent
  5. Review the VLAN port configuration table.
    SEFOS# show vlan port config port extreme-ethernet 0/15
    Vlan Port configuration table
    Port Ex0/15
    Port Vlan ID                       : 5
    Port Acceptable Frame Type         : Admit Only Vlan Tagged
    Port Ingress Filtering             : Disabled
    Port Mode                          : Hybrid
    Port Gvrp Status                   : Enabled
    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
    Tunnel Status                      : Disabled
    Dot1x Protocol Tunnel Status       : Peer
    LACP Protocol Tunnel Status        : Peer
    Spanning Tree Tunnel Status        : Peer
    GVRP Protocol Tunnel Status        : Peer
    GMRP Protocol Tunnel Status        : Peer
    IGMP Protocol Tunnel Status        : Peer
    Filtering Utility Criteria         : Default
    Port Protected Status              : Disabled

    After you configure the acceptable frame type as Admit OnlyVLAN Tagged, the ping from host A to host B should fail because ping(1M) packets are untagged.
