Dell Converged Enhanced Ethernet Administrator’s Guide 3753-1002116-01VLAN configuration and management 5Configuring an interface port as a trunk interfaceEach CEE interface port supports admission policies based on whether the frames are untagged ortagged. Trunk mode admits only VLAN-tagged frames.To configure the interface as a trunk interface, perform the following steps from Privileged EXECmode.1. Enter the configure terminal command to access global configuration mode.2. Enter the interface command to specify the CEE interface type and slot/port number.switch(config)#interface intengigabitethernet 0/193. Enter the no shutdown command to enable the CEE interface.4. Enter the switchport command to place the CEE interface into trunk mode.switch(conf-if-te-0/19)#switchport mode trunk5. Specify whether all, one, or none of the VLAN interfaces are allowed to transmit and receivethrough the CEE interface. Enter the following command that is appropriate for your needs.• This example allows the VLAN numbered as 30 to transmit/receive through the CEEinterface:switch(conf-if-te-0/19)#switchport trunk allowed vlan add 30• To allow all VLANs to transmit/receive through the CEE interface:switch(conf-if-te-0/19)#switchport trunk allowed vlan all• This example allows all except VLAN 11 to transmit/receive through the CEE interface:switch(conf-if-te-0/19)#switchport trunk allowed vlan except 11• To allow none of the VLANs to transmit/receive through the CEE interface:switch(conf-if-te-0/19)#switchport trunk allowed vlan noneDisabling a VLAN on a trunk interfaceTo disable a VLAN on a trunk interface, perform the following steps from Privileged EXEC mode.1. Enter the configure terminal command to access global configuration mode.2. Enter the interface command to specify the CEE interface type and slot/port number.switch(config)#interface intengigabitethernet 0/103. Enter the no shutdown command to enable the CEE interface.4. Enter the switchport command to place the CEE interface into trunk mode.switch(conf-if-te-0/10)#switchport mode trunk noneConfiguring an interface port as a converged interfaceEach CEE interface port supports admission policies based on whether the frames are untagged ortagged. Converged mode admits both tagged and untagged frames. Any tagged frames comingwith a VLAN tag equal to the configured native VLAN are dropped.
