loopback on vlan interfaces

[sie.xarxa.edu]

Hi there,

do anyone know about the utility of the "loopback set" flag under the Vlan interface command. Could it help to keep a vlan in up/up state for example?

Thanx.

A vlan interface is indeed "virtual". Setting the loopback will have little effect.

A vlan interface will be up/up when there is at least one member port for the vlan with an active link. A single active trunk port will suffice as well to get the interface active.

Hi Leo,

Thank you for your feedback.

I understand that, but what loopback (under vlan interface) does then? i mean what is the difference/utlity to get "loopback set" mention?
