owed by the VLAN number and name: 2950-IOS(vlan)# vlan 10 name Lab-VLAN VLAN 10 added: Name: Lab-VLAN You can show the VLANs configured from within VLAN database mode with the command show. You have the option of displaying the current database (show current), the differences between the current and proposed database (show changes), or the proposed database as it will look after you apply the changes using the apply command or exit VLAN database configuration mode. The default behavior of the show command is show proposed: 2950-IOS(vlan)# show VLAN ISL Id: 1 Name: default Media Type: Ethernet VLAN 802.10 Id: 100001 State: Operational MTU: 1500 Backup CRF Mode: Disabled Remote SPAN VLAN: No VLAN ISL Id: 10 Name: Lab-VLAN Media Type Ethernet VLAN 802.10 Id: 100010 State: Operational MTU: 1500 Backup CRF Mode: Disabled Remote SPAN VLAN: No Nothing else is required to create a simple VLAN. The database will be saved upon exit: 2950-IOS(vlan)# exit APPLY completed. Exiting Chapter 4: VLANs Now, when you execute the show vlan command in IOS, you'll see the VLAN you've created: 2950-IOS# sho vlan VLAN Name Status Ports default active Fa0/1, Fa0/2, Fa0/3, Fao/4 Fa0/5, Fao/6, Fa0/7, Fa0/8 Fa0/9, Fa0/10, Fa0/11, Fa0/12 Fa0/13, Fa0/14, Fa0/15, Fa0/16 Fa0/17, Fa0/18, Fa0/19, Fa0/20 Fa0/21, Fa0/22, Fa0/23, Fao/24 Gi0/1, Gio/2 Lab-VLAN active 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active Adding ports to the VLAN is accomplished in IOS interface configuration mode, and is covered in the next section. IOS Using Global Commands Adding VLANs in IOS is relatively straightforward when all of the defaults are acceptable, which is usually the case. First, enter configuration mode. From there, issue the vlan command with the identifier for the VLAN you're adding or changing. Next, specify a name for the VLAN with the name subcommand (as with CatOS, a default name of VLANxxxx is used if you do not supply one): 2950-IOS# conf t Enter configuration commands, one per line.
