Keeping VLAN interface UP

Hi, all!


This post enquires about keeping VLAN interface UP. Please have a look below to find out more.


ISSUE DESCRIPTION


Is there an equivalent to Cisco's no autostate? I have some remote AR169's and when a single onsite PC gets shut down, the router will have no physical interfaces up, so the VLAN int drops, causing monitoring issues.


Any ideas? I have found delay timers, but not a no autostate equivalent.


Thanks for assisting me in keeping VLAN interface UP.

I'm also looking for the "no autostate" equivalent in Huawei.
Can we associate a virtual interface to the vlan?

Thanks.

After 6 months I revive this topic since I've not been able to find a solution for the same problem.

I have an S5720 switch and I need to monitor an IP bound to a vlan interface, but there isn't any port in the up state associated with that vlan.
I found a way to delay the down state of the vlanif interface (damping time 20), but not an equivalent of Cisco's "no autostate".
Do someone know a solution (the configuration of a trunk is not a solution).
Thanks :)

I'm happy that you decide to resurrect this thread.

What do you think about the following idea:

You can find an unused interface, that doesn't have anything connected on it, configure vlan X on the interface as trunk or access, then set the interface to stay "up" using "loopback internal" command.
For example:
<HUAWEI> system-view
[HUAWEI] interface gigabitethernet 0/0/1
[HUAWEI-GigabitEthernet0/0/1] loopback internal

This should help to achieve your goal and keep vlanif up all the time.
