interface vlan does not up!

[huydien3384]

Hi all,

I create a vlan follows an interface vlan, but the interface vlan does not up.

I'm using RSP7600 Adv IP Service with ES20 line card. Please help.

Thanks million!

Certainly I've created vlan on router and shutdown, no shutdown interface vlan, but it still down :( Any suggestion?

Hello,

A SVI interface for a VLAN X will be up/up if there is an access port alive in the VLAN X on the switch, or if there is a trunk port alive on the switch on which the VLAN X is allowed. Are these requirements met in your particular case?

Best regards,

Peter
