Default Vlan (Vlan 1) is down

[liulianqing]

I create Vlan 1, but see Vlan 1 is down.

#sh int vlan 1

Vlan1 is down, line protocol is down.

can someone explain the reason.

Thanks.

In order for your VLAN1 to show up/up one of the following two conditions should hold:

1) There should be one active (physically up) access port in VLAN 1.

2) VLAN1 should be carried in an active trunk on the switch (normally it is).

This is because of a feature called autostate which brings up the logical interface (vlan interface) up only when there is a physical device on that VLAN.

Hi. You need to connect atleast one port from switch to other device.

After that , you will get Vlan 1 ( Default) is up and operational.

click on the switch

click on the CLI tab

type in :

enable

configure terminal

int vlan 1

no shutdown

(enter)

,then it'll be all right
