Trunk port changes assigned VLANs spontaneously

[igorlazo99]

Hello,

I have problem with GE2 port VLAN membership in trunk mode.

When I set GE2 port as a trunk for VLAN 11 tagged, VLAN 48 tagged

and VLAN 666 untagged+PVID, it stays so only untill reboot.

After reboot there are 11, 48 and 666 tagged, while VLAN 1

untagged+PVID. Everything works somehow, but there are warnings.

Default VLAN 11. The other side is 2960G with no vtp on port

and vtp is globally off.

Thank you

Igor,

Might need to call Cisco Small Business Support Center @ 1-866-606-1866 and open a support case for your issue.

Hi Igor

Just out of interest, I see no mention that you saved the configuration in your problem description.

As the administrators guide says on page 30,  Configurations will be lost if not saved.

Just in case you didn't save your configuration, here is a 6 minute video that shows,  in the last minute,  how to save the configuration of a 300 series switch, but it should be identical for a 200 series product..

https://cisco.webex.com/ciscosales/lsr.php?AT=pb&SP=MC&rID=56220782&rKey=5fc47a1c7b566b8c

or try from the GUI

Click Administration > File Management > Copy/Save Configuration

Copy the running configuration to the startup configuration.

If you have saved your configuration but still lose VLAN assignment, yes please follow the advice in the previous posting.

regards Dave
