简单排除VLAN无线上网交换机故障[3]

  Enter configuration commands, one per line. End with CNTL/Z.

  6509（config）#interface gigabitEthernet 5/2

  6509（config-if）#switchport trunk ?

  allowed Set allowed VLAN characteristics when interface is in trunking mode

  encapsulation Set trunking encapsulation when interface is in trunking mode

  native Set trunking native characteristics when interface is in t runking mode

  pruning Set pruning VLAN characteristics when interface is in trunking mode
