VLAN not saving in Catalyst 3850

[brocfriend]

Hello,

I am trying to configure VLANs in my catalyst 3850 switch. I add my vlans, apply and click ok and refresh. My VLAN's are deleted and only the default VLAN is available.

Hi,

Are you using the cli to add the vlans?

If you are on the cli, issue "sh run" and look for the vlans you created.

Also, "show vlan" will show you all vlans.

Hello,

according to the documentation, you have to also specify the media type:

3850#conf t

3850(config)#vlan 20

3850(config-vlan)#media ethernet

The last step doesn't seem to be optional, but required...

Hello

is this switch in production and if so is it in an vtp domain? 

What vtp version is running - It could be possible vtp 3 if running and as a result of that - Then only a primary vtp server can change the vtp database.

Another reason could inconsistencies with the startup config and the vtp database being read from the vlan.dat file in NVRAM (this is the file from where vlan information is saved and read from)

Sonif inconsistencies are apparent then default vlan config could be applied to the switch on reload

Lastly if this vlan.dat file cannot be read for some reason or is missing completely - This also would not save your vlan changes

can you post:

sh vtp status 

dir flash:
