We have VLAN 1 disabled on our standard Cisco Catalyst switches and use VLAN 11 as our default. We have recently added VLAN 221 for voice while implementing a new Cisco UC system. I can't seem to disable VLAN1, however, I have made the default VLAN 11 and Voice VLAN 221. In VLAN Management, I can untag VLAN 11 (PVID) on all ports but the Gigabit port connecting to the Cisco 6506. That port always tags VLAN 11 & 221 and untag (PVID) VLAN 1.
I have tried making changes to the switch while connected to the switch and when I make the setting, the switch loses connection to the 6506. If I make the appropriate changes to GI(1) while connected to GI(2), that change takes effect, however, when I move the patch cable to GI(1), the port configuration changes and VLAN 11 becomes tagged and VLAN1 becomes untagged.
What is needed to stop this from happening?
The smartport roles negotiated the links and seem to have resolved manually setting the port configurations.
Additionally, SX300 series do not support Remote SPAN, therfore the silent monitoring will not work between the UCCX and the phones while connecting to the switch(es).
