Hi, all!

Have log in stack of X670V
10/28/2015
11:24:07.40 Slot-2: exvlan: setVpifState:3075: KERNEL_EXVLAN_ERROR: failed to find VPIF 0 [slot 256 port 32] on VLAN 1000020

10/28/2015 11:24:07.40 Slot-2: exvlan: setVpifState:3075: KERNEL_EXVLAN_ERROR: failed to find VPIF 0 [slot 256 port 31] on VLAN 1000020

After that vlan 2935 is automatically disabled.
After enable this vlan - enable vlan "VLAN_2935_SIP" this logs appear again

Any ideas?

Thank you!

Does this error pop up immediately after enabling the VLAN? Or is there a delay between the VLAN being enabled and the logs appearing?

Also, was this working previously, or is this a new implementation? If it was working, were there any changes recently made?

First time - almost at once with login to switch:

10/28/2015 11:23:56.73 [i] Slot-1: Msg from Master : Did password authentication for user duzhvenko (10.10.200.24)

10/28/2015 11:23:56.73 [i] Slot-1: Login passed for user duzhvenko through ssh (10.10.200.24)

Second time after enable vlan.

New configuration - it's create 4 new vlans with tags and ports.

Thank you!

After a quick search, I don't see any known issues that seem to match this, but it does seem like it may be a bug.

It may be best to open up a case with GTAC so we can look into this deeper. I'd suggest attaching the .cfg file to the case, in addition to a show tech.

Hi, Brandon!

Case is opened.
Isn't "show tech-sup all" contain "sh conf" section?

Thank you!

Hi Alexandr,

'show tech all' does include 'show conf', but the .cfg is actually an XML file, which is the actual config file that the switch reads on boot. I'm thinking that there may be something strange in the config, so having the actual XML file that the switch loads the config from would be helpful. You can see the config file that was booted in the output of 'show switch', and you can TFTP this file off to a TFTP server.

If you do 'upload debug', this will also get the current .cfg file.

Hello, Brandon!

What exactly information I can give you for investigate this problem?
We investigate that this log-message appear 2 times after disable and after enable VLAN.
As this stack in the Customers core he is worry about it.
Where I can give you .cfg file for parallel investigate? Or have you a time to watch this?

Thank you!

I have not seen the case or documents but may I ask how many VLANs are on the switch and are all ports added to all of these VLANs?? Any VPIF errors are related to VLAN and port mappings. There is a fixed number of ports and VLAN combinations within XOS that was set some time ago when XOS was first off the ground. I had some discussion regarding this when a customer of mine wanted to create 4000 VLANs and add all ports from a loaded X8 to all VLANs, which in this case exceeded VPIF allocations within XOS.
