Remove Port From Native Vlan / PC 5224
I'm having a hard time assigning VLANs on my PowerConnect 5224. I can't seem to remove ports from Vlan1 to save my life. I want specifically to place et 1/1 and 1/22 in vlan 20. I want et 1/22 to be a .1q trunk-port to aggrigate multiple vlan's yet to be configured.
I've tried "no switchport native vlan 1" and "switchport allowed vlan remove 1" and any other combination I can think of to remove this port from vlan 1 but I can't seem to make it work. I get something similar to Failed to remove from egress list on ethernet 1/22.
Typing conf -> int eth 1/22 -> switchport native vlan 20 gives me
Vty-0(config-if)#switchport native vlan 20
Failed to set pvid on ethernet 1/22
Attached is my config. How can I remove 1/22 and 1/1 from vlan 1? Any help would be greatly appreciated.

building running-config, please wait.....

OK. Thanks. I made the suggested changes, but if I read the config right, eth 1/22 still sends frames on Vlan1 as untagged. How do I make all VLANs tagged going out 1/22?

Failed to remove from egress list on ethernet 1/22I must misunderstand native vlans. 1/22 should be tagging all vlans. 1,20 and any other I decide to create. How do I make the port above belong to vlan 1 and 20 and tag all frames?

If ethernet 1/1 will be an untagged port on VLAN 20, the configuration you would use would be:
(config-if)# switchport allowed vlan add 20
(config-if)# switchport native vlan 20
(config-if)# switchport allowed vlan remove 1
For ethernet 1/22, you usually would not want to remove VLAN 1 on an 802.1q trunk. If you do, you will not be able to manage the switch across the trunk. The native VLAN for a trunk port must be the same on both switches. Unless you have modified it on the other switch, the native VLAN for a trunk is usually VLAN 1 (the typical management VLAN for the switch). The configuration I would suggest on interface 1/22, would be:
(config-if)# switchport allowed vlan rem 20
(config-if)# switchport allowed vlan add 20 tagged
All other VLANs that will be trunked would be added as tagged on this port as well.
FYI... A port cannot be tagged on its native VLAN. On a trunk port, the native VLAN is understood to be tagged. Therefore, you want to configure the native VLAN as untagged and all other VLANs tagged.
