Update!

I updated a switch to IOS XE 3.7.0E. Now the VLANs are set correctly in the config file. So this appears to have been a Cisco bug.

However, the description still never gets set. The following error shows up in the apache2 log:

[Thu Dec 18 11:07:01 2014] [error] [Thu Dec 18 11:07:01 2014] [INFO] [pid=16607 nav.web.portadmin] ktobias: wladc-acc-sw-03:Gi2/0/30 - ifalias set to "NAV Test"

[Thu Dec 18 11:07:05 2014] [error] [Thu Dec 18 11:07:05 2014] [ERROR] [pid=16607 nav.web.portadmin] Error doing write mem on wladc-acc-sw-03: Timed out waiting for SNMP response: Timeout

Another question. Is the "enable" behavior by design? As long as I have been using NAV (~1yr), any change to a port config VLAN or description results in the port being "shutdown". Even if the "enable" checkbox is selected. I have to then refresh the page to query the new status, check the "enable" box with is now not selected and save.

Below are some excerpts from one of the switches in question. Using the NAV "Configure Ports" button from the device page to get the entire list of ports, I set the name of g1/0/30 to "NAV Test" and the VLAN to 501. The same result is seen while using the "Configure Port" button from the specific port page.

"Before" shows that g1/0/30 is not in VLAN 501 and has no description using "show vlan id", "sh run int" and "sh int desc".

"After" shows that "sh vlan id" has g1/0/30 in vlan 501 and that "sh int desc" has the correct description while a "show run int" does not reflect these changes.

#sh ver

Hope this helps. Please let me know if you would like additional output or diagnostics.

BTW, has anyone tried this on any other platform (not just 3850) using IOS XE 3.6.1E or something close?

I'd like to point out that we only heard this about NX-OS software (Cisco
Nexus products). We don't know yet that they have the same plans for IOS.

What would be interesting, Ken Tobias, is to know the two software
versions of your working and your not-entirely-working 3850's.

Also, one of our network engineers was interested in seeing an example
difference in output between `show vlan` and `show running` which
demonstrates the "ephemeral" setting of VLANs you mentioned. He'd never
heard of such a thing :-)
