The NEM provides flexibility in managing ingress VLAN traffic. For example, you can set port ingress filtering to enabled and can also specify the acceptable frame type to implement fine-grained control on the ingress traffic. Refer to the Sun Ethernet Fabric Operating System CLI Base Reference Manual for details.
For example:
SEFOS# show vlan port config port extreme-ethernet 0/3 Vlan Port configuration table ------------------------------- Port Ex0/3 Port Vlan ID : 1 Port Acceptable Frame Type : Admit All 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 Filtering Utility Criteria : Default Port Protected Status : Disabled -------------------------------------------------------
For example, to reconfigure the 10GbE port Ex0/3 as a tagged port in vlan 3 and allowing only tagged frames.
SEFOS# config terminal SEFOS(config)# vlan 3 SEFOS(config-vlan)# port extreme-ethernet 0/3 SEFOS(config-vlan)# exit SEFOS(config)# interface extreme-ethernet 0/3 SEFOS(config-if)# switchport ingress-filter SEFOS(config-if)# switchport acceptable-frame-type tagged SEFOS(config-if)# end SEFOS# show vlan port config port extreme-ethernet 0/3 Vlan Port configuration table ------------------------------- Port Ex0/3 Port Vlan ID : 1 Port Acceptable Frame Type : Admit Only Vlan Tagged Port Ingress Filtering : Enabled 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 Filtering Utility Criteria : Default Port Protected Status : Disabled
