任务 4：创建、修改、删除 vlan
步骤 1：进入交换机 SW1 的全局配置模式
Switch>enable Switch#configure terminal Enter configuration commands, one per line. End with CNTL/Z. Switch(config)#
步骤 2：使用 hostname 命令指定主机名为 SW1
Switch(config)#hostname SW1 SW1(config)#
步骤 3：创建一个 vlan，vlan 号为 100， 名字为“SALES”
SW1(config)#vlan 100 SW1(config-vlan)#name SALES SW1(config-vlan)#exit SW1(config)#
步骤 4：回到特权模式
SW1(config)#exit SW1#
步骤 5：使用 show vlan brief 命令，检查 vlan 数据库，并确认 vlan100
SW1#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4 Fa0/5, Fa0/6, 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, Fa0/24 Gig0/1, Gig0/2 100 SALES active 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active
步骤 6：进入全局配置模式，将 vlan100 的名称改为“SUPPORTS”
SW1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. SW1(config)#vlan 100 SW1(config-vlan)#name SUPPORTS SW1(config-vlan)#exit SW1(config)#exit
步骤 7：再次检查 vlan 数据库，确认 vlan100 的名称已被更改
SW1#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4 Fa0/5, Fa0/6, 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, Fa0/24 Gig0/1, Gig0/2 100 SUPPORTS active 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active
步骤 8：进入全局配置模式，将 vlan100 删除
SW1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. SW1(config)#no vlan 100 SW1(config)#exit SW1#
步骤 9：检查 vlan 数据库，确认 vlan100 已被删除
SW1#show vlan brief VLAN Name Status Ports ---- -------------------------------- --------- ------------------------------- 1 default active Fa0/1, Fa0/2, Fa0/3, Fa0/4 Fa0/5, Fa0/6, 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, Fa0/24 Gig0/1, Gig0/2 1002 fddi-default active 1003 token-ring-default active 1004 fddinet-default active 1005 trnet-default active
