VLAN configuration and management

4

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. 

Example  of selecting the Ten Gigabit Ethernet port number 0/1.

switch(config)#interface tengigabitethernet 0/1

3. Enter the no shutdown command to enable the CEE interface.

4. Enter the switchport command to configure the CEE interface as a Layer 2 switch port. 

switch(conf-if-te-0/1)#switchport access vlan 20

Configuring an interface port as a trunk interface

Each CEE interface port supports admission policies based on whether the frames are untagged or 
tagged. Trunk mode admits only VLAN-tagged frames.

To configure the interface as 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. 

Example  of selecting the Ten Gigabit Ethernet port number 0/19.

switch(config)#interface tengigabitethernet 0/19

3. 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 trunk

5. Specify whether all, one, or none of the VLAN interfaces are allowed to transmit and receive 

through 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 CEE 
interface:

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 none

Disabling a VLAN on a trunk interface

To 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. 

Example  of selecting the Ten Gigabit Ethernet port number 0/10.

switch(config)#interface tengigabitethernet 0/10

3. Enter the no shutdown command to enable the CEE interface.
