IOS Using Global Commands Adding VLANs in IOS is relatively straightforward when all of the defaults are accept- able, which is usually the case. Here I'll revert to a 3750, since you're likely to encounter modern switches using this method. 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): 3750-IOS#conf t Enter configuration commands, one per line. End with CNTL/Z. 3750-I0S(config)# vlan 10 3750-I0S(config-vlan)# name Lab-VLAN Exit configuration mode and then issue the show vlan command to see the VLANs present: 3750-IOS#sho vlan VLAN Name Status Ports default active Gi1/0/1, Gi1/0/2, Gi1/0/3 Gi1/0/4, Gi1/0/5, Gi1/0/6 Gi1/0/7, Gi1/0/8, Gi1/0/9 Gi1/0/10, Gi1/0/11, Gi1/0/12 Gi1/0/13, Gi1/0/14, Gi1/0/15 Gi1/0/16, Gi1/0/17, Gi1/0/18 Gi1/0/21, Gi1/0/22, Gi1/0/23 Gi1/0/24, Gi1/0/25, Gi1/0/26 Gi1/0/27, Gi1/0/28, Gi1/0/29 Gi1/0/30, Gi1/0/31, Gi1/0/32 Gi1/0/33, Gi1/0/34, Gi1/0/35 Gi1/0/36, Gi1/0/37, Gi1/0/38 Gi1/0/39, Gi1/0/40, Gi1/0/41 Gi1/0/42, Gi1/0/43, Gi1/0/44 Gi1/0/46, Gi1/0/49, Gi1/0/50 Gi1/0/51, Gi1/0/52 10 Lab-VLAN active 100 VLAN0100 active 200 VLAN0200 active 300 VLAN0300 active VLAN Name Status Ports 1002 fddi-default act/unsup 1003 token-ring-default act/unsup Configuring VLANs 1004 fddinet-default act/unsup 1005 trnet-default act/unsup VLAN Type SAID Parent RingNo BridgeNo Stp BrdgMode Trans1 Trans2 1 enet 100001 10 enet 100010 10
