Hi Leo,


I haven't tried upgrading the IOS yet.

I already downloaded the IOS in case an upgrade is needed.


If I could create extended VLAN in transparent mode. Then my problem is solve.


Thanks for the reply.

Hi,


Could you please try to change the VTP operation mode to Transparent. Then create an extended VLAN. If it doesn't work then I have no choice but to change the switch.


Thanks and regards,


Gil

Hi Gil,


Apologize for wasting your time. The 2900/3500 switches are very "simple" models. I have a nagging suspicion it doesn't support extended VLANs but I can't confirm because I couldn't find any documentations nor do I have a sample to test it out.

Hi Leo,


If this is not doable then I have no choice but to change the switch.
